+# API Changelog
+
+This changelog is intended to list all updates to the [public API methods](https://xrpl.org/public-api-methods.html).
+
+For info about how [API versioning](https://xrpl.org/request-formatting.html#api-versioning) works, including examples, please view the [XLS-22d spec](https://github.com/XRPLF/XRPL-Standards/discussions/54). For details about the implementation of API versioning, view the [implementation PR](https://github.com/XRPLF/rippled/pull/3155). API versioning ensures existing integrations and users continue to receive existing behavior, while those that request a higher API version will experience new behavior.
+
+The API version controls the API behavior you see. This includes what properties you see in responses, what parameters you're permitted to send in requests, and so on. You specify the API version in each of your requests. When a breaking change is introduced to the `rippled` API, a new version is released. To avoid breaking your code, you should set (or increase) your version when you're ready to upgrade.
+
+For a log of breaking changes, see the **API Version [number]** headings. In general, breaking changes are associated with a particular API Version number. For non-breaking changes, scroll to the **XRP Ledger version [x.y.z]** headings. Non-breaking changes are associated with a particular XRP Ledger (`rippled`) release.
+
+## API Version 2
+
+API version 2 is available in `rippled` version 2.0.0 and later. To use this API, clients specify `"api_version" : 2` in each request.
+
+#### Removed methods
+
+In API version 2, the following deprecated methods are no longer available: (https://github.com/XRPLF/rippled/pull/4759)
+
+- `tx_history` - Instead, use other methods such as `account_tx` or `ledger` with the `transactions` field set to `true`.
+- `ledger_header` - Instead, use the `ledger` method.
+
+#### Modifications to JSON transaction element in V2
+
+In API version 2, JSON elements for transaction output have been changed and made consistent for all methods which output transactions. (https://github.com/XRPLF/rippled/pull/4775)
+This helps to unify the JSON serialization format of transactions. (https://github.com/XRPLF/clio/issues/722, https://github.com/XRPLF/rippled/issues/4727)
+
+- JSON transaction element is named `tx_json`
+- Binary transaction element is named `tx_blob`
+- JSON transaction metadata element is named `meta`
+- Binary transaction metadata element is named `meta_blob`
+
+Additionally, these elements are now consistently available next to `tx_json` (i.e. sibling elements), where possible:
+
+- `hash` - Transaction ID. This data was stored inside transaction output in API version 1, but in API version 2 is a sibling element.
+- `ledger_index` - Ledger index (only set on validated ledgers)
+- `ledger_hash` - Ledger hash (only set on closed or validated ledgers)
+- `close_time_iso` - Ledger close time expressed in ISO 8601 time format (only set on validated ledgers)
+- `validated` - Bool element set to `true` if the transaction is in a validated ledger, otherwise `false`
+
+This change affects the following methods:
+
+- `tx` - Transaction data moved into element `tx_json` (was inline inside `result`) or, if binary output was requested, moved from `tx` to `tx_blob`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
+- `account_tx` - Renamed transaction element from `tx` to `tx_json`. Renamed binary transaction metadata element (if it was requested) from `meta` to `meta_blob`. Changed location of `hash` and added new elements
+- `transaction_entry` - Renamed transaction metadata element from `metadata` to `meta`. Changed location of `hash` and added new elements
+- `subscribe` - Renamed transaction element from `transaction` to `tx_json`. Changed location of `hash` and added new elements
+- `sign`, `sign_for`, `submit` and `submit_multisigned` - Changed location of `hash` element.
+
+#### Modification to `Payment` transaction JSON schema
+
+When reading Payments, the `Amount` field should generally **not** be used. Instead, use [delivered_amount](https://xrpl.org/partial-payments.html#the-delivered_amount-field) to see the amount that the Payment delivered. To clarify its meaning, the `Amount` field is being renamed to `DeliverMax`. (https://github.com/XRPLF/rippled/pull/4733)
+
+- In `Payment` transaction type, JSON RPC field `Amount` is renamed to `DeliverMax`. To enable smooth client transition, `Amount` is still handled, as described below: (https://github.com/XRPLF/rippled/pull/4733)
+  - On JSON RPC input (e.g. `submit_multisigned` etc. methods), `Amount` is recognized as an alias to `DeliverMax` for both API version 1 and version 2 clients.
+  - On JSON RPC input, submitting both `Amount` and `DeliverMax` fields is allowed _only_ if they are identical; otherwise such input is rejected with `rpcINVALID_PARAMS` error.
+  - On JSON RPC output (e.g. `subscribe`, `account_tx` etc. methods), `DeliverMax` is present in both API version 1 and version 2.
+  - On JSON RPC output, `Amount` is only present in API version 1 and _not_ in version 2.
+
+#### Modifications to account_info response
+
+- `signer_lists` is returned in the root of the response. (In API version 1, it was nested under `account_data`.) (https://github.com/XRPLF/rippled/pull/3770)
+- When using an invalid `signer_lists` value, the API now returns an "invalidParams" error. (https://github.com/XRPLF/rippled/pull/4585)
+  - (`signer_lists` must be a boolean. In API version 1, strings were accepted and may return a normal response - i.e. as if `signer_lists` were `true`.)
+
+#### Modifications to [account_tx](https://xrpl.org/account_tx.html#account_tx) response
+
+- Using `ledger_index_min`, `ledger_index_max`, and `ledger_index` returns `invalidParams` because if you use `ledger_index_min` or `ledger_index_max`, then it does not make sense to also specify `ledger_index`. In API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4571)
+  - The same applies for `ledger_index_min`, `ledger_index_max`, and `ledger_hash`. (https://github.com/XRPLF/rippled/issues/4545#issuecomment-1565065579)
+- Using a `ledger_index_min` or `ledger_index_max` beyond the range of ledgers that the server has:
+  - returns `lgrIdxMalformed` in API version 2. Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/issues/4288)
+- Attempting to use a non-boolean value (such as a string) for the `binary` or `forward` parameters returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
+
+#### Modifications to [noripple_check](https://xrpl.org/noripple_check.html#noripple_check) response
+
+- Attempting to use a non-boolean value (such as a string) for the `transactions` parameter returns `invalidParams` (`rpcINVALID_PARAMS`). Previously, in API version 1, no error was returned. (https://github.com/XRPLF/rippled/pull/4620)
+
+## API Version 1
+
+This version is supported by all `rippled` versions. For WebSocket and HTTP JSON-RPC requests, it is currently the default API version used when no `api_version` is specified.
+
+The [commandline](https://xrpl.org/docs/references/http-websocket-apis/api-conventions/request-formatting/#commandline-format) always uses the latest API version. The command line is intended for ad-hoc usage by humans, not programs or automated scripts. The command line is not meant for use in production code.
+
+### Inconsistency: server_info - network_id
+
+The `network_id` field was added in the `server_info` response in version 1.5.0 (2019), but it is not returned in [reporting mode](https://xrpl.org/rippled-server-modes.html#reporting-mode). However, use of reporting mode is now discouraged, in favor of using [Clio](https://github.com/XRPLF/clio) instead.
+
+## XRP Ledger server version 2.5.0
+
+As of 2025-04-04, version 2.5.0 is in development. You can use a pre-release version by building from source or [using the `nightly` package](https://xrpl.org/docs/infrastructure/installation/install-rippled-on-ubuntu).
+
+### Additions and bugfixes in 2.5.0
+
+- `channel_authorize`: If `signing_support` is not enabled in the config, the RPC is disabled.
+
+## XRP Ledger server version 2.4.0
+
+[Version 2.4.0](https://github.com/XRPLF/rippled/releases/tag/2.4.0) was released on March 4, 2025.
+
+### Additions and bugfixes in 2.4.0
+
+- `ledger_entry`: `state` is added an alias for `ripple_state`.
+- `ledger_entry`: Enables case-insensitive filtering by canonical name in addition to case-sensitive filtering by RPC name.
+- `validators`: Added new field `validator_list_threshold` in response.
+- `simulate`: A new RPC that executes a [dry run of a transaction submission](https://github.com/XRPLF/XRPL-Standards/tree/master/XLS-0069d-simulate#2-rpc-simulate)
+- Signing methods autofill fees better and properly handle transactions that don't have a base fee, and will also autofill the `NetworkID` field.
+
+## XRP Ledger server version 2.3.0
+
+[Version 2.3.0](https://github.com/XRPLF/rippled/releases/tag/2.3.0) was released on Nov 25, 2024.
+
+### Breaking changes in 2.3.0
+
+- `book_changes`: If the requested ledger version is not available on this node, a `ledgerNotFound` error is returned and the node does not attempt to acquire the ledger from the p2p network (as with other non-admin RPCs).
+
+Admins can still attempt to retrieve old ledgers with the `ledger_request` RPC.
+
+### Additions and bugfixes in 2.3.0
+
+- `book_changes`: Returns a `validated` field in its response, which was missing in prior versions.
+
+## XRP Ledger server version 2.2.0
+
+[Version 2.2.0](https://github.com/XRPLF/rippled/releases/tag/2.2.0) was released on Jun 5, 2024. The following additions are non-breaking (because they are purely additive):
+
+- The `feature` method now has a non-admin mode for users. (It was previously only available to admin connections.) The method returns an updated list of amendments, including their names and other information. ([#4781](https://github.com/XRPLF/rippled/pull/4781))
+
+## XRP Ledger server version 2.0.0
+
+[Version 2.0.0](https://github.com/XRPLF/rippled/releases/tag/2.0.0) was released on Jan 9, 2024. The following additions are non-breaking (because they are purely additive):
+
+- `server_definitions`: A new RPC that generates a `definitions.json`-like output that can be used in XRPL libraries.
+- In `Payment` transactions, `DeliverMax` has been added. This is a replacement for the `Amount` field, which should not be used. Typically, the `delivered_amount` (in transaction metadata) should be used. To ease the transition, `DeliverMax` is present regardless of API version, since adding a field is non-breaking.
+- API version 2 has been moved from beta to supported, meaning that it is generally available (regardless of the `beta_rpc_api` setting).
+
+## XRP Ledger server version 2.2.0
+
+The following is a non-breaking addition to the API.
+
+- The `feature` method now has a non-admin mode for users. (It was previously only available to admin connections.) The method returns an updated list of amendments, including their names and other information. ([#4781](https://github.com/XRPLF/rippled/pull/4781))
+
+## XRP Ledger server version 1.12.0
+
+[Version 1.12.0](https://github.com/XRPLF/rippled/releases/tag/1.12.0) was released on Sep 6, 2023. The following additions are non-breaking (because they are purely additive).
+
+- `server_info`: Added `ports`, an array which advertises the RPC and WebSocket ports. This information is also included in the `/crawl` endpoint (which calls `server_info` internally). `grpc` and `peer` ports are also included. (https://github.com/XRPLF/rippled/pull/4427)
+  - `ports` contains objects, each containing a `port` for the listening port (a number string), and a `protocol` array listing the supported protocols on that port.
+  - This allows crawlers to build a more detailed topology without needing to port-scan nodes.
+  - (For peers and other non-admin clients, the info about admin ports is excluded.)
+- Clawback: The following additions are gated by the Clawback amendment (`featureClawback`). (https://github.com/XRPLF/rippled/pull/4553)
+  - Adds an [AccountRoot flag](https://xrpl.org/accountroot.html#accountroot-flags) called `lsfAllowTrustLineClawback` (https://github.com/XRPLF/rippled/pull/4617)
+    - Adds the corresponding `asfAllowTrustLineClawback` [AccountSet Flag](https://xrpl.org/accountset.html#accountset-flags) as well.
+    - Clawback is disabled by default, so if an issuer desires the ability to claw back funds, they must use an `AccountSet` transaction to set the AllowTrustLineClawback flag. They must do this before creating any trust lines, offers, escrows, payment channels, or checks.
+  - Adds the [Clawback transaction type](https://github.com/XRPLF/XRPL-Standards/blob/master/XLS-39d-clawback/README.md#331-clawback-transaction), containing these fields:
+    - `Account`: The issuer of the asset being clawed back. Must also be the sender of the transaction.
+    - `Amount`: The amount being clawed back, with the `Amount.issuer` being the token holder's address.
+- Adds [AMM](https://github.com/XRPLF/XRPL-Standards/discussions/78) ([#4294](https://github.com/XRPLF/rippled/pull/4294), [#4626](https://github.com/XRPLF/rippled/pull/4626)) feature:
+  - Adds `amm_info` API to retrieve AMM information for a given tokens pair.
+  - Adds `AMMCreate` transaction type to create `AMM` instance.
+  - Adds `AMMDeposit` transaction type to deposit funds into `AMM` instance.
+  - Adds `AMMWithdraw` transaction type to withdraw funds from `AMM` instance.
+  - Adds `AMMVote` transaction type to vote for the trading fee of `AMM` instance.
+  - Adds `AMMBid` transaction type to bid for the Auction Slot of `AMM` instance.
+  - Adds `AMMDelete` transaction type to delete `AMM` instance.
+  - Adds `sfAMMID` to `AccountRoot` to indicate that the account is `AMM`'s account. `AMMID` is used to fetch `ltAMM`.
+  - Adds `lsfAMMNode` `TrustLine` flag to indicate that one side of the `TrustLine` is `AMM` account.
+  - Adds `tfLPToken`, `tfSingleAsset`, `tfTwoAsset`, `tfOneAssetLPToken`, `tfLimitLPToken`, `tfTwoAssetIfEmpty`,
+    `tfWithdrawAll`, `tfOneAssetWithdrawAll` which allow a trader to specify different fields combination
+    for `AMMDeposit` and `AMMWithdraw` transactions.
+  - Adds new transaction result codes:
+    - tecUNFUNDED_AMM: insufficient balance to fund AMM. The account does not have funds for liquidity provision.
+    - tecAMM_BALANCE: AMM has invalid balance. Calculated balances greater than the current pool balances.
+    - tecAMM_FAILED: AMM transaction failed. Fails due to a processing failure.
+    - tecAMM_INVALID_TOKENS: AMM invalid LP tokens. Invalid input values, format, or calculated values.
+    - tecAMM_EMPTY: AMM is in empty state. Transaction requires AMM in non-empty state (LP tokens > 0).
+    - tecAMM_NOT_EMPTY: AMM is not in empty state. Transaction requires AMM in empty state (LP tokens == 0).
+    - tecAMM_ACCOUNT: AMM account. Clawback of AMM account.
+    - tecINCOMPLETE: Some work was completed, but more submissions required to finish. AMMDelete partially deletes the trustlines.
+
+## XRP Ledger server version 1.11.0
+
+[Version 1.11.0](https://github.com/XRPLF/rippled/releases/tag/1.11.0) was released on Jun 20, 2023.
+
+### Breaking changes in 1.11
+
+- Added the ability to mark amendments as obsolete. For the `feature` admin API, there is a new possible value for the `vetoed` field. (https://github.com/XRPLF/rippled/pull/4291)
+  - The value of `vetoed` can now be `true`, `false`, or `"Obsolete"`.
+- Removed the acceptance of seeds or public keys in place of account addresses. (https://github.com/XRPLF/rippled/pull/4404)
+  - This simplifies the API and encourages better security practices (i.e. seeds should never be sent over the network).
+- For the `ledger_data` method, when all entries are filtered out, the `state` field of the response is now an empty list (in other words, an empty array, `[]`). (Previously, it would return `null`.) While this is technically a breaking change, the new behavior is consistent with the documentation, so this is considered only a bug fix. (https://github.com/XRPLF/rippled/pull/4398)
+- If and when the `fixNFTokenRemint` amendment activates, there will be a new AccountRoot field, `FirstNFTSequence`. This field is set to the current account sequence when the account issues their first NFT. If an account has not issued any NFTs, then the field is not set. ([#4406](https://github.com/XRPLF/rippled/pull/4406))
+  - There is a new account deletion restriction: an account can only be deleted if `FirstNFTSequence` + `MintedNFTokens` + `256` is less than the current ledger sequence.
+  - This is potentially a breaking change if clients have logic for determining whether an account can be deleted.
+- NetworkID
+  - For sidechains and networks with a network ID greater than 1024, there is a new [transaction common field](https://xrpl.org/transaction-common-fields.html), `NetworkID`. (https://github.com/XRPLF/rippled/pull/4370)
+    - This field helps to prevent replay attacks and is now required for chains whose network ID is 1025 or higher.
+    - The field must be omitted for Mainnet, so there is no change for Mainnet users.
+  - There are three new local error codes:
+    - `telNETWORK_ID_MAKES_TX_NON_CANONICAL`: a `NetworkID` is present but the chain's network ID is less than 1025. Remove the field from the transaction, and try again.
+    - `telREQUIRES_NETWORK_ID`: a `NetworkID` is required, but is not present. Add the field to the transaction, and try again.
+    - `telWRONG_NETWORK`: a `NetworkID` is specified, but it is for a different network. Submit the transaction to a different server which is connected to the correct network.
+
+### Additions and bug fixes in 1.11
+
+- Added `nftoken_id`, `nftoken_ids` and `offer_id` meta fields into NFT `tx` and `account_tx` responses. (https://github.com/XRPLF/rippled/pull/4447)
+- Added an `account_flags` object to the `account_info` method response. (https://github.com/XRPLF/rippled/pull/4459)
+- Added `NFTokenPages` to the `account_objects` RPC. (https://github.com/XRPLF/rippled/pull/4352)
+- Fixed: `marker` returned from the `account_lines` command would not work on subsequent commands. (https://github.com/XRPLF/rippled/pull/4361)
+
+## XRP Ledger server version 1.10.0
+
+[Version 1.10.0](https://github.com/XRPLF/rippled/releases/tag/1.10.0)
+was released on Mar 14, 2023.
+
+### Breaking changes in 1.10
+
+- If the `XRPFees` feature is enabled, the `fee_ref` field will be
+  removed from the [ledger subscription stream](https://xrpl.org/subscribe.html#ledger-stream), because it will no longer
+  have any meaning.
+
+# Unit tests for API changes
+
+The following information is useful to developers contributing to this project:
+
+The purpose of unit tests is to catch bugs and prevent regressions. In general, it often makes sense to create a test function when there is a breaking change to the API. For APIs that have changed in a new API version, the tests should be modified so that both the prior version and the new version are properly tested.
+
+To take one example: for `account_info` version 1, WebSocket and JSON-RPC behavior should be tested. The latest API version, i.e. API version 2, should be tested over WebSocket, JSON-RPC, and command line.

 ## Steps
 
-
 ### Set Up Conan
 
-1. (Optional) If you've never used Conan, use autodetect to set up a default profile.
+After you have a [C++ development environment](./docs/build/environment.md) ready with Git, Python, Conan, CMake, and a C++ compiler, you may need to set up your Conan profile.
+
+These instructions assume a basic familiarity with Conan and CMake.
+
+If you are unfamiliar with Conan, then please read [this crash course](./docs/build/conan.md) or the official [Getting Started][3] walkthrough.
+
+You'll need at least one Conan profile:
+
+```
+conan profile detect --force
+```
+
+Update the compiler settings:
+
+   For Conan 2, you can edit the profile directly at `~/.conan2/profiles/default`,
+   or use the Conan CLI. Ensure C++20 is set:
 
    ```
-   conan profile new default --detect
+   conan profile show
    ```
 
-2. Update the compiler settings.
+   Look for `compiler.cppstd=20` in the output. If it's not set, edit the profile:
 
    ```
-   conan profile update settings.compiler.cppstd=20 default
+   # Edit ~/.conan2/profiles/default and ensure these settings exist:
+   [settings]
+   compiler.cppstd=20
    ```
 
-   Linux developers will commonly have a default Conan [profile][] that compiles
-   with GCC and links with libstdc++.
-   If you are linking with libstdc++ (see profile setting `compiler.libcxx`),
-   then you will need to choose the `libstdc++11` ABI.
+Configure Conan (1.x only) to use recipe revisions:
 
    ```
-   conan profile update settings.compiler.libcxx=libstdc++11 default
+   conan config set general.revisions_enabled=1
    ```
 
-   On Windows, you should use the x64 native build tools.
-   An easy way to do that is to run the shortcut "x64 Native Tools Command
-   Prompt" for the version of Visual Studio that you have installed.
+**Linux** developers will commonly have a default Conan [profile][] that compiles

+If you are linking with libstdc++ (see profile setting `compiler.libcxx`),
+then you will need to choose the `libstdc++11` ABI:
 
-   Windows developers must also build `rippled` and its dependencies for the x64
+   ```
+   # In ~/.conan2/profiles/default, ensure:
+   [settings]
+   compiler.libcxx=libstdc++11
+   ```
+
+
+Ensure inter-operability between `boost::string_view` and `std::string_view` types:
+
+```
+conan profile update 'conf.tools.build:cxxflags+=["-DBOOST_BEAST_USE_STD_STRING_VIEW"]' default
+conan profile update 'env.CXXFLAGS="-DBOOST_BEAST_USE_STD_STRING_VIEW"' default
+```
+
+If you have other flags in the `conf.tools.build` or `env.CXXFLAGS` sections, make sure to retain the existing flags and append the new ones. You can check them with:
+```
+conan profile show default
+```
+
+

+   Windows developers must also build `xahaud` and its dependencies for the x64
    architecture.
 
    ```
-   conan profile update settings.arch=x86_64 default
+   # In ~/.conan2/profiles/default, ensure:
+   [settings]
+   arch=x86_64
    ```
 
-3. (Optional) If you have multiple compilers installed on your platform,
-   make sure that Conan and CMake select the one you want to use.
-   This setting will set the correct variables (`CMAKE_<LANG>_COMPILER`)
-   in the generated CMake toolchain file.
+### Multiple compilers
 
    ```
-   conan profile update 'conf.tools.build:compiler_executables={"c": "<path>", "cpp": "<path>"}' default
+   # In ~/.conan2/profiles/default, add under [conf] section:
+   [conf]
+   tools.build:compiler_executables={"c": "<path>", "cpp": "<path>"}
    ```
 
-   It should choose the compiler for dependencies as well,
-   but not all of them have a Conan recipe that respects this setting (yet).
-   For the rest, you can set these environment variables:
+   For setting environment variables for dependencies:

-   conan profile update env.CC=<path> default
-   conan profile update env.CXX=<path> default
+   # In ~/.conan2/profiles/default, add under [buildenv] section:
+   [buildenv]
+   CC=<path>
+   CXX=<path>
    ```

+## Coverage report
+
+The coverage report is intended for developers using compilers GCC
+or Clang (including Apple Clang). It is generated by the build target `coverage`,
+which is only enabled when the `coverage` option is set, e.g. with
+`--options coverage=True` in `conan` or `-Dcoverage=ON` variable in `cmake`
+
+Prerequisites for the coverage report:
+
+- [gcovr tool][gcovr] (can be installed e.g. with [pip][python-pip])
+- `gcov` for GCC (installed with the compiler by default) or
+- `llvm-cov` for Clang (installed with the compiler by default)
+- `Debug` build type
+
+A coverage report is created when the following steps are completed, in order:
+
+1. `rippled` binary built with instrumentation data, enabled by the `coverage`
+   option mentioned above
+2. completed run of unit tests, which populates coverage capture data
+3. completed run of the `gcovr` tool (which internally invokes either `gcov` or `llvm-cov`)
+   to assemble both instrumentation data and the coverage capture data into a coverage report
+
+The above steps are automated into a single target `coverage`. The instrumented
+`rippled` binary can also be used for regular development or testing work, at
+the cost of extra disk space utilization and a small performance hit
+(to store coverage capture). In case of a spurious failure of unit tests, it is
+possible to re-run the `coverage` target without rebuilding the `rippled` binary
+(since it is simply a dependency of the coverage report target). It is also possible
+to select only specific tests for the purpose of the coverage report, by setting
+the `coverage_test` variable in `cmake`
+
+The default coverage report format is `html-details`, but the user
+can override it to any of the formats listed in `cmake/CodeCoverage.cmake`
+by setting the `coverage_format` variable in `cmake`. It is also possible
+to generate more than one format at a time by setting the `coverage_extra_args`
+variable in `cmake`. The specific command line used to run the `gcovr` tool will be
+displayed if the `CODE_COVERAGE_VERBOSE` variable is set.
+
+By default, the code coverage tool runs parallel unit tests with `--unittest-jobs`
+set to the number of available CPU cores. This may cause spurious test
+errors on Apple. Developers can override the number of unit test jobs with
+the `coverage_test_parallelism` variable in `cmake`.
+
+Example use with some cmake variables set:
+
+```
+cd .build
+conan install .. --output-folder . --build missing --settings build_type=Debug
+cmake -DCMAKE_BUILD_TYPE=Debug -Dcoverage=ON -Dxrpld=ON -Dtests=ON -Dcoverage_test_parallelism=2 -Dcoverage_format=html-details -Dcoverage_extra_args="--json coverage.json" -DCMAKE_TOOLCHAIN_FILE:FILEPATH=build/generators/conan_toolchain.cmake ..
+cmake --build . --target coverage
+```
+
+After the `coverage` target is completed, the generated coverage report will be
+stored inside the build directory, as either of:
+
+- file named `coverage.`_extension_ , with a suitable extension for the report format, or
+- directory named `coverage`, with the `index.html` and other files inside, for the `html-details` or `html-nested` report formats.

-If your compiler version is recent enough to have removed `std::result_of` as
-part of C++20, e.g. Apple Clang 15.0, then you might need to add a preprocessor
-definition to your build.
+If you're on macOS with Apple Clang 17 or newer, you need to add a compiler flag to work around a compilation error in gRPC dependencies.
+
+Edit `~/.conan2/profiles/default` and add under the `[conf]` section:
 
 ```
-conan profile update 'options.boost:extra_b2_flags="define=BOOST_ASIO_HAS_STD_INVOKE_RESULT"' default

+
+If you are compiling with an early version of Clang 16, then you might hit
+a [regression][6] when compiling C++20 that manifests as an [error in a Boost

 Header includes must be [levelized](./Builds/levelization).
 
+Changes should be usually squashed down into a single commit.
+Some larger or more complicated change sets make more sense,
+and are easier to review if organized into multiple logical commits.
+Either way, all commits should fit the following criteria:
+
+- Changes should be presented in a single commit or a logical
+  sequence of commits.
+  Specifically, chronological commits that simply
+  reflect the history of how the author implemented
+  the change, "warts and all", are not useful to
+  reviewers.
+- Every commit should have a [good message](#good-commit-messages).
+  to explain a specific aspects of the change.
+- Every commit should be signed.
+- Every commit should be well-formed (builds successfully,
+  unit tests passing), as this helps to resolve merge
+  conflicts, and makes it easier to use `git bisect`
+  to find bugs.
+
+### Good commit messages
+
+Refer to
+["How to Write a Git Commit Message"](https://cbea.ms/git-commit/)
+for general rules on writing a good commit message.
+
+tl;dr
+
+> 1. Separate subject from body with a blank line.
+> 2. Limit the subject line to 50 characters.
+>    - [...]shoot for 50 characters, but consider 72 the hard limit.
+> 3. Capitalize the subject line.
+> 4. Do not end the subject line with a period.
+> 5. Use the imperative mood in the subject line.
+>    - A properly formed Git commit subject line should always be able
+>      to complete the following sentence: "If applied, this commit will
+>      _your subject line here_".
+> 6. Wrap the body at 72 characters.
+> 7. Use the body to explain what and why vs. how.
+
+In addition to those guidelines, please add one of the following
+prefixes to the subject line if appropriate.
+
+- `fix:` - The primary purpose is to fix an existing bug.
+- `perf:` - The primary purpose is performance improvements.
+- `refactor:` - The changes refactor code without affecting
+  functionality.
+- `test:` - The changes _only_ affect unit tests.
+- `docs:` - The changes _only_ affect documentation. This can
+  include code comments in addition to `.md` files like this one.
+- `build:` - The changes _only_ affect the build process,
+  including CMake and/or Conan settings.
+- `chore:` - Other tasks that don't affect the binary, but don't fit
+  any of the other cases. e.g. formatting, git settings, updating
+  Github Actions jobs.
+
+Whenever possible, when updating commits after the PR is open, please
+add the PR number to the end of the subject line. e.g. `test: Add
+unit tests for Feature X (#1234)`.
 
 ## Pull requests
 
 In general, pull requests use `develop` as the base branch.
-
 (Hotfixes are an exception.)
 
-Changes to pull requests must be added as new commits.
-Once code reviewers have started looking at your code, please avoid
-force-pushing a branch in a pull request.
+If your changes are not quite ready, but you want to make it easily available
+for preliminary examination or review, you can create a "Draft" pull request.
+While a pull request is marked as a "Draft", you can rebase or reorganize the
+commits in the pull request as desired.

+Github pull requests are created as "Ready" by default, or you can mark
+a "Draft" pull request as "Ready".
+Once a pull request is marked as "Ready",
+any changes must be added as new commits. Do not
+force-push to a branch in a pull request under review.
+(This includes rebasing your branch onto the updated base branch.
+Use a merge operation, instead or hit the "Update branch" button
+at the bottom of the Github PR page.)
 This preserves the ability for reviewers to filter changes since their last
 review.

-can be considered for merge by a Maintainer.
+A pull request must obtain **approvals from at least two reviewers**
+before it can be considered for merge by a Maintainer.
 Maintainers retain discretion to require more approvals if they feel the
 credibility of the existing approvals is insufficient.
 
 Pull requests must be merged by [squash-and-merge][2]
 to preserve a linear history for the `develop` branch.
 
+### When and how to merge pull requests
+
+#### "Passed"
+
+A pull request should only have the "Passed" label added when it
+meets a few criteria:
+
+1. It must have two approving reviews [as described
+   above](#pull-requests). (Exception: PRs that are deemed "trivial"
+   only need one approval.)
+2. All CI checks must be complete and passed. (One-off failures may
+   be acceptable if they are related to a known issue.)
+3. The PR must have a [good commit message](#good-commit-messages).
+   - If the PR started with a good commit message, and it doesn't
+     need to be updated, the author can indicate that in a comment.
+   - Any contributor, preferably the author, can leave a comment
+     suggesting a commit message.
+   - If the author squashes and rebases the code in preparation for
+     merge, they should also ensure the commit message(s) are updated
+     as well.
+4. The PR branch must be up to date with the base branch (usually
+   `develop`). This is usually accomplised by merging the base branch
+   into the feature branch, but if the other criteria are met, the
+   changes can be squashed and rebased on top of the base branch.
+5. Finally, and most importantly, the author of the PR must
+   positively indicate that the PR is ready to merge. That can be
+   accomplished by adding the "Passed" label if their role allows,
+   or by leaving a comment to the effect that the PR is ready to
+   merge.
+
+Once the "Passed" label is added, a maintainer may merge the PR at
+any time, so don't use it lightly.
+
+#### Instructions for maintainers
+
+The maintainer should double-check that the PR has met all the
+necessary criteria, and can request additional information from the
+owner, or additional reviews, and can always feel free to remove the
+"Passed" label if appropriate. The maintainer has final say on
+whether a PR gets merged, and are encouraged to communicate and
+issues or concerns to other maintainers.
+
+##### Most pull requests: "Squash and merge"
+
+Most pull requests don't need special handling, and can simply be
+merged using the "Squash and merge" button on the Github UI. Update
+the suggested commit message if necessary.
+
+##### Slightly more complicated pull requests
+
+Some pull requests need to be pushed to `develop` as more than one
+commit. There are multiple ways to accomplish this. If the author
+describes a process, and it is reasonable, follow it. Otherwise, do
+a fast forward only merge (`--ff-only`) on the command line and push.
+
+Either way, check that:
+* The commits are based on the current tip of `develop`.
+* The commits are clean: No merge commits (except when reverse
+  merging), no "[FOLD]" or "fixup!" messages.
+* All commits are signed. If the commits are not signed by the author, use
+  `git commit --amend -S` to sign them yourself.
+* At least one (but preferably all) of the commits has the PR number
+  in the commit message.
+
+**Never use the "Create a merge commit" or "Rebase and merge"
+ functions!**
+
+##### Releases, release candidates, and betas
+
+All releases, including release candidates and betas, are handled
+differently from typical PRs. Most importantly, never use
+the Github UI to merge a release.
+
+1. There are two possible conditions that the `develop` branch will
+   be in when preparing a release.
+   1. Ready or almost ready to go: There may be one or two PRs that
+      need to be merged, but otherwise, the only change needed is to
+      update the version number in `BuildInfo.cpp`. In this case,
+      merge those PRs as appropriate, updating the second one, and
+      waiting for CI to finish in between. Then update
+      `BuildInfo.cpp`.
+   2. Several pending PRs: In this case, do not use the Github UI,
+      because the delays waiting for CI in between each merge will be
+      unnecessarily onerous. Instead, create a working branch (e.g.
+      `develop-next`) based off of `develop`. Squash the changes
+      from each PR onto the branch, one commit each (unless
+      more are needed), being sure to sign each commit and update
+      the commit message to include the PR number. You may be able
+      to use a fast-forward merge for the first PR. The workflow may
+      look something like:
+```
+git fetch upstream
+git checkout upstream/develop
+git checkout -b develop-next
+# Use -S on the ff-only merge if prbranch1 isn't signed.
+# Or do another branch first.
+git merge --ff-only user1/prbranch1
+git merge --squash user2/prbranch2
+git commit -S
+git merge --squash user3/prbranch3
+git commit -S
+[...]
+git push --set-upstream origin develop-next
+</pre>
+```
+2. Create the Pull Request with `release` as the base branch. If any
+   of the included PRs are still open,
+   [use closing keywords](https://docs.github.com/articles/closing-issues-using-keywords)
+   in the description to ensure they are closed when the code is
+   released. e.g. "Closes #1234"
+3. Instead of the default template, reuse and update the message from
+   the previous release. Include the following verbiage somewhere in
+   the description:
+```
+The base branch is release. All releases (including betas) go in
+release. This PR will be merged with --ff-only (not squashed or
+rebased, and not using the GitHub UI) to both release and develop.
+```
+4. Sign-offs for the three platforms usually occur offline, but at
+   least one approval will be needed on the PR.
+5. Once everything is ready to go, open a terminal, and do the
+   fast-forward merges manually. Do not push any branches until you
+   verify that all of them update correctly.
+```
+git fetch upstream
+git checkout -b upstream--develop -t upstream/develop || git checkout upstream--develop
+git reset --hard upstream/develop
+# develop-next must be signed already!
+git merge --ff-only origin/develop-next
+git checkout -b upstream--release -t upstream/release || git checkout upstream--release
+git reset --hard upstream/release
+git merge --ff-only origin/develop-next
+# Only do these 3 steps if pushing a release. No betas or RCs
+git checkout -b upstream--master -t upstream/master || git checkout upstream--master
+git reset --hard upstream/master
+git merge --ff-only origin/develop-next
+# Check that all of the branches are updated
+git log -1 --oneline
+# The output should look like:
+# 02ec8b7962 (HEAD -> upstream--master, origin/develop-next, upstream--release, upstream--develop, develop-next) Set version to 2.2.0-rc1
+# Note that all of the upstream--develop/release/master are on this commit.
+# (Master will be missing for betas, etc.)
+# Just to be safe, do a dry run first:
+git push --dry-run upstream-push HEAD:develop
+git push --dry-run upstream-push HEAD:release
+# git push --dry-run upstream-push HEAD:master
+# Now push
+git push upstream-push HEAD:develop
+git push upstream-push HEAD:release
+# git push upstream-push HEAD:master
+# Don't forget to tag the release, too.
+git tag <version number>
+git push upstream-push <version number>
+```
+6. Finally
+[create a new release on Github](https://github.com/XRPLF/rippled/releases).

+## Contracts and instrumentation
+
+We are using [Antithesis](https://antithesis.com/) for continuous fuzzing,
+and keep a copy of [Antithesis C++ SDK](https://github.com/antithesishq/antithesis-sdk-cpp/)
+in `external/antithesis-sdk`. One of the aims of fuzzing is to identify bugs
+by finding external conditions which cause contracts violations inside `rippled`.
+The contracts are expressed as `XRPL_ASSERT` or `UNREACHABLE` (defined in
+`include/xrpl/beast/utility/instrumentation.h`), which are effectively (outside
+of Antithesis) wrappers for `assert(...)` with added name. The purpose of name
+is to provide contracts with stable identity which does not rely on line numbers.
+
+When `rippled` is built with the Antithesis instrumentation enabled
+(using `voidstar` CMake option) and ran on the Antithesis platform, the
+contracts become
+[test properties](https://antithesis.com/docs/using_antithesis/properties.html);
+otherwise they are just like a regular `assert`.
+To learn more about Antithesis, see
+[How Antithesis Works](https://antithesis.com/docs/introduction/how_antithesis_works.html)
+and [C++ SDK](https://antithesis.com/docs/using_antithesis/sdk/cpp/overview.html#)
+
+We continue to use the old style `assert` or `assert(false)` in certain
+locations, where the reporting of contract violations on the Antithesis
+platform is either not possible or not useful.
+
+For this reason:
+
+- The locations where `assert` or `assert(false)` contracts should continue to be used:
+  - `constexpr` functions
+  - unit tests i.e. files under `src/test`
+  - unit tests-related modules (files under `beast/test` and `beast/unit_test`)
+- Outside of the listed locations, do not use `assert`; use `XRPL_ASSERT` instead,
+  giving it unique name, with the short description of the contract.
+- Outside of the listed locations, do not use `assert(false)`; use
+  `UNREACHABLE` instead, giving it unique name, with the description of the
+  condition being violated
+- The contract name should start with a full name (including scope) of the
+  function, optionally a named lambda, followed by a colon `:` and a brief
+  (typically at most five words) description. `UNREACHABLE` contracts
+  can use slightly longer descriptions. If there are multiple overloads of the
+  function, use common sense to balance both brevity and unambiguity of the
+  function name. NOTE: the purpose of name is to provide stable means of
+  unique identification of every contract; for this reason try to avoid elements
+  which can change in some obvious refactors or when reinforcing the condition.
+- Contract description typically (except for `UNREACHABLE`) should describe the
+  _expected_ condition, as in "I assert that _expected_ is true".
+- Contract description for `UNREACHABLE` should describe the _unexpected_
+  situation which caused the line to have been reached.
+- Example good name for an
+  `UNREACHABLE` macro `"Json::operator==(Value, Value) : invalid type"`; example
+  good name for an `XRPL_ASSERT` macro `"Json::Value::asCString : valid type"`.
+- Example **bad** name
+  `"RFC1751::insert(char* s, int x, int start, int length) : length is greater than or equal zero"`
+  (missing namespace, unnecessary full function signature, description too verbose).
+  Good name: `"ripple::RFC1751::insert : minimum length"`.
+- In **few** well-justified cases a non-standard name can be used, in which case a
+  comment should be placed to explain the rationale (example in `contract.cpp`)
+- Do **not** rename a contract without a good reason (e.g. the name no longer
+  reflects the location or the condition being checked)
+- Do not use `std::unreachable`
+- Do not put contracts where they can be violated by an external condition
+  (e.g. timing, data payload before mandatory validation etc.) as this creates
+  bogus bug reports (and causes crashes of Debug builds)
+
+## Unit Tests
+
+To execute all unit tests:
+
+`rippled --unittest --unittest-jobs=<number of cores>`
+
+(Note: Using multiple cores on a Mac M1 can cause spurious test failures. The
+cause is still under investigation. If you observe this problem, try specifying fewer jobs.)
+
+To run a specific set of test suites:
+
+```
+rippled --unittest TestSuiteName
+```
+
+Note: In this example, all tests with prefix `TestSuiteName` will be run, so if
+`TestSuiteName1` and `TestSuiteName2` both exist, then both tests will run.
+Alternatively, if the unit test name finds an exact match, it will stop
+doing partial matches, i.e. if a unit test with a title of `TestSuiteName`
+exists, then no other unit test will be executed, apart from `TestSuiteName`.

Transactions submitted to the Xahau network must supply an appropriate amount of XAH, to be burnt by the network as a fee, in order to be successfully included in a validated ledger. In addition, XAH also acts as a bridge currency within the Xahau DEX. XAH is traded on the open-market and is available for anyone to access. Xahau was created in 2023 with a supply of 600 million units of XAH.

+# CHANGES:
+#
+# 2012-01-31, Lars Bilke
+# - Enable Code Coverage
+#
+# 2013-09-17, Joakim Söderberg
+# - Added support for Clang.
+# - Some additional usage instructions.
+#
+# 2016-02-03, Lars Bilke
+# - Refactored functions to use named parameters
+#
+# 2017-06-02, Lars Bilke
+# - Merged with modified version from github.com/ufz/ogs
+#
+# 2019-05-06, Anatolii Kurotych
+# - Remove unnecessary --coverage flag
+#
+# 2019-12-13, FeRD (Frank Dana)
+# - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor
+#   of tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments.
+# - CMake 3.4+: All excludes can be specified relative to BASE_DIRECTORY
+# - All setup functions: accept BASE_DIRECTORY, EXCLUDE list
+# - Set lcov basedir with -b argument
+# - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be
+#   overridden with NO_DEMANGLE option in setup_target_for_coverage_lcovr().)
+# - Delete output dir, .info file on 'make clean'
+# - Remove Python detection, since version mismatches will break gcovr
+# - Minor cleanup (lowercase function names, update examples...)
+#
+# 2019-12-19, FeRD (Frank Dana)
+# - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
+#
+# 2020-01-19, Bob Apthorpe
+# - Added gfortran support
+#
+# 2020-02-17, FeRD (Frank Dana)
+# - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters
+#   in EXCLUDEs, and remove manual escaping from gcovr targets
+#
+# 2021-01-19, Robin Mueller
+# - Add CODE_COVERAGE_VERBOSE option which will allow to print out commands which are run
+# - Added the option for users to set the GCOVR_ADDITIONAL_ARGS variable to supply additional
+#   flags to the gcovr command
+#
+# 2020-05-04, Mihchael Davis
+#     - Add -fprofile-abs-path to make gcno files contain absolute paths
+#     - Fix BASE_DIRECTORY not working when defined
+#     - Change BYPRODUCT from folder to index.html to stop ninja from complaining about double defines
+#
+# 2021-05-10, Martin Stump
+#     - Check if the generator is multi-config before warning about non-Debug builds
+#
+# 2022-02-22, Marko Wehle
+#     - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output respectively.
+#       This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS, e.g. GCOVR_ADDITIONAL_ARGS "--txt".
+#
+# 2022-09-28, Sebastian Mueller
+#     - fix append_coverage_compiler_flags_to_target to correctly add flags
+#     - replace "-fprofile-arcs -ftest-coverage" with "--coverage" (equivalent)
+#
+# 2024-01-04, Bronek Kozicki
+#     - remove setup_target_for_coverage_lcov (slow) and setup_target_for_coverage_fastcov (no support for Clang)
+#     - fix Clang support by adding find_program( ... llvm-cov )
+#     - add Apple Clang support by adding execute_process( COMMAND xcrun -f llvm-cov ... )
+#     - add CODE_COVERAGE_GCOV_TOOL to explicitly select gcov tool and disable find_program
+#     - replace both functions setup_target_for_coverage_gcovr_* with a single setup_target_for_coverage_gcovr
+#     - add support for all gcovr output formats
+#
+# 2024-04-03, Bronek Kozicki
+#     - add support for output formats: jacoco, clover, lcov
+#
+# 2025-05-12, Jingchen Wu
+#     - add -fprofile-update=atomic to ensure atomic profile generation
+#
+# 2025-08-28, Bronek Kozicki
+#     - fix "At least one COMMAND must be given" CMake warning from policy CMP0175
+#
+# 2025-09-03, Jingchen Wu
+#     - remove the unused function append_coverage_compiler_flags and append_coverage_compiler_flags_to_target
+#     - add a new function add_code_coverage_to_target
+#     - remove some unused code
+#
+# USAGE:
+#
+# 1. Copy this file into your cmake modules path.
+#
+# 2. Add the following line to your CMakeLists.txt (best inside an if-condition
+#    using a CMake option() to enable it just optionally):
+#      include(CodeCoverage)
+#
+# 3. Append necessary compiler flags and linker flags for all supported source files:
+#      add_code_coverage_to_target(<target> <PRIVATE|PUBLIC|INTERFACE>)
+#
+# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
+#
+# 4. If you need to exclude additional directories from the report, specify them
+#    using full paths in the COVERAGE_EXCLUDES variable before calling
+#    setup_target_for_coverage_*().
+#    Example:
+#      set(COVERAGE_EXCLUDES
+#          '${PROJECT_SOURCE_DIR}/src/dir1/*'
+#          '/path/to/my/src/dir2/*')
+#    Or, use the EXCLUDE argument to setup_target_for_coverage_*().
+#    Example:
+#      setup_target_for_coverage_gcovr(
+#          NAME coverage
+#          EXECUTABLE testrunner
+#          EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*" "/path/to/my/src/dir2/*")
+#
+# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set
+#     relative to the BASE_DIRECTORY (default: PROJECT_SOURCE_DIR)
+#     Example:
+#       set(COVERAGE_EXCLUDES "dir1/*")
+#       setup_target_for_coverage_gcovr(
+#           NAME coverage
+#           EXECUTABLE testrunner
+#           FORMAT html-details
+#           BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src"
+#           EXCLUDE "dir2/*")
+#
+# 4.b If you need to pass specific options to gcovr, specify them in
+#     GCOVR_ADDITIONAL_ARGS variable.
+#     Example:
+#       set (GCOVR_ADDITIONAL_ARGS --exclude-throw-branches --exclude-noncode-lines -s)
+#       setup_target_for_coverage_gcovr(
+#           NAME coverage
+#           EXECUTABLE testrunner
+#           EXCLUDE "src/dir1" "src/dir2")
+#
+# 5. Use the functions described below to create a custom make target which
+#    runs your test executable and produces a code coverage report.
+#
+# 6. Build a Debug build:
+#      cmake -DCMAKE_BUILD_TYPE=Debug ..
+#      make
+#      make my_coverage_target

-This document contains instructions for installing rippled.
-The APT package manager is common on Debian-based Linux distributions like
-Ubuntu,
-while the YUM package manager is common on Red Hat-based Linux distributions
-like CentOS.
-Installing from source is an option for all platforms,
-and the only supported option for installing custom builds.
+Comprehensive instructions for installing and running xahaud are available on the [https://Xahau.Network](https://xahau.network/docs/infrastructure/installing-xahaud) documentation website.
 
+## Create the Runtime Environment
+xahaud can be [built from source](../../BUILD.md) or installed using the binary files available from [https://build.xahau.tech](https://build.xahau.tech/). After obtaining a working xahaud binary, users will need to provide a suitable runtime environment. The following setup can be used for Linux or Docker environments.
 
-## From source
-
-From a source build, you can install rippled and libxrpl using CMake's
-`--install` mode:
+1. Create or download two configuration files: the main xahaud.cfg configuration file and a second validators-xahau.txt file defining which validators or UNL list publishers are trusted. The default location for these files in this xahaud repository is `cfg/`.
+2. Provide a directory structure that is congruent with the contents of xahaud.cfg. This will include a location for logfiles, such as `/var/log/xahaud/`, as well as database files, `/opt/xahaud/db/`. Configuration files are, by default, sourced from `/etc/xahaud/`. It is possible to provide a symbolic link, if users wish to store configuration files elsewhere.
+3. If desired, created a xahaud user and group, and change ownership of the binary and directories. Servers used for validating nodes should use the most restrictive permissions possible for `xahaud.cfg`, as the validation token is stored therein.
+4. If desired, create a systemd service file: `/etc/systemd/system/xahaud.service`, enabling xahaud to run as a daemon. Alternately, run: `/path/to/binary/xahaud --conf=/path/to/xahaud.cfg`.
 
+## Example systemd Service File
 ```
-cmake --install . --prefix /opt/local
+[Unit]
+Description=Xahaud Daemon
+After=network-online.target
+Wants=network-online.target

+[Install]
+WantedBy=multi-user.target

-The default [prefix][1] is typically `/usr/local` on Linux and macOS and
-`C:/Program Files/rippled` on Windows.

-## With the APT package manager
-
-1. Update repositories:
-
-        sudo apt update -y
-
-2. Install utilities:
-
-        sudo apt install -y apt-transport-https ca-certificates wget gnupg
-
-3. Add Ripple's package-signing GPG key to your list of trusted keys:
-
-        sudo mkdir /usr/local/share/keyrings/
-        wget -q -O - "https://repos.ripple.com/repos/api/gpg/key/public" | gpg --dearmor > ripple-key.gpg
-        sudo mv ripple-key.gpg /usr/local/share/keyrings
-
-
-4. Check the fingerprint of the newly-added key:
-
-        gpg /usr/local/share/keyrings/ripple-key.gpg
-
-    The output should include an entry for Ripple such as the following:
-
-        gpg: WARNING: no command supplied.  Trying to guess what you mean ...
-        pub   rsa3072 2019-02-14 [SC] [expires: 2026-02-17]
-            C0010EC205B35A3310DC90DE395F97FFCCAFD9A2
-        uid           TechOps Team at Ripple <techops+rippled@ripple.com>
-        sub   rsa3072 2019-02-14 [E] [expires: 2026-02-17]
-
-
-    In particular, make sure that the fingerprint matches. (In the above example, the fingerprint is on the third line, starting with `C001`.)
-
-4. Add the appropriate Ripple repository for your operating system version:
-
-        echo "deb [signed-by=/usr/local/share/keyrings/ripple-key.gpg] https://repos.ripple.com/repos/rippled-deb focal stable" | \
-            sudo tee -a /etc/apt/sources.list.d/ripple.list
-
-    The above example is appropriate for **Ubuntu 20.04 Focal Fossa**. For other operating systems, replace the word `focal` with one of the following:
-
-    - `jammy` for **Ubuntu 22.04 Jammy Jellyfish**
-    - `bionic` for **Ubuntu 18.04 Bionic Beaver**
-    - `bullseye` for **Debian 11 Bullseye**
-    - `buster` for **Debian 10 Buster**
-
-    If you want access to development or pre-release versions of `rippled`, use one of the following instead of `stable`:
-
-    - `unstable` - Pre-release builds ([`release` branch](https://github.com/ripple/rippled/tree/release))
-    - `nightly` - Experimental/development builds ([`develop` branch](https://github.com/ripple/rippled/tree/develop))
-
-    **Warning:** Unstable and nightly builds may be broken at any time. Do not use these builds for production servers.
-
-5. Fetch the Ripple repository.
-
-        sudo apt -y update
-
-6. Install the `rippled` software package:
-
-        sudo apt -y install rippled
-
-7. Check the status of the `rippled` service:
-
-        systemctl status rippled.service
-
-    The `rippled` service should start automatically. If not, you can start it manually:
-
-        sudo systemctl start rippled.service
-
-8. Optional: allow `rippled` to bind to privileged ports.
-
-    This allows you to serve incoming API requests on port 80 or 443. (If you want to do so, you must also update the config file's port settings.)
-
-        sudo setcap 'cap_net_bind_service=+ep' /opt/ripple/bin/rippled
-
-
-## With the YUM package manager
-
-1. Install the Ripple RPM repository:
-
-    Choose the appropriate RPM repository for the stability of releases you want:
-
-    - `stable` for the latest production release (`master` branch)
-    - `unstable` for pre-release builds (`release` branch)
-    - `nightly` for experimental/development builds (`develop` branch)
-
-    *Stable*
-
-        cat << REPOFILE | sudo tee /etc/yum.repos.d/ripple.repo
-        [ripple-stable]

-        gpgkey=https://repos.ripple.com/repos/rippled-rpm/unstable/repodata/repomd.xml.key
-        REPOFILE
-
-    *Nightly*
-

-        gpgkey=https://repos.ripple.com/repos/rippled-rpm/nightly/repodata/repomd.xml.key
-        REPOFILE
-
-2. Fetch the latest repo updates:
-
-        sudo yum -y update
-
-3. Install the new `rippled` package:
-
-        sudo yum install -y rippled
-
-4. Configure the `rippled` service to start on boot:
-
-        sudo systemctl enable rippled.service
-
-5. Start the `rippled` service:
-
-        sudo systemctl start rippled.service
+After the systemd service file is installed, it must be loaded with: `systemctl daemon-reload`. xahaud can then be enabled: `systemctl enable --now xahaud`.

+# Antithesis C++ SDK
+
+This library provides methods for C++ programs to configure the [Antithesis](https://antithesis.com) platform. It contains three kinds of functionality:
+
+- Assertion macros that allow you to define test properties about your software or workload.
+- Randomness functions for requesting both structured and unstructured randomness from the Antithesis platform.
+- Lifecycle functions that inform the Antithesis environment that particular test phases or milestones have been reached.
+
+For general usage guidance see the [Antithesis C++ SDK Documentation](https://antithesis.com/docs/using_antithesis/sdk/cpp/overview/)
