-## Renaming ripple(d) to xrpl(d)
-
-In the initial phases of development of the XRPL, the open source codebase was
-called "rippled" and it remains with that name even today. Today, over 1000
-nodes run the application, and code contributions have been submitted by
-developers located around the world. The XRPL community is larger than ever.
-In light of the decentralized and diversified nature of XRPL, we will rename any
-references to `ripple` and `rippled` to `xrpl` and `xrpld`, when appropriate.
-
-See [here](https://xls.xrpl.org/xls/XLS-0095-rename-rippled-to-xrpld.html) for
-more information.
-
-### Scripts
-
-To facilitate this transition, there will be multiple scripts that developers
-can run on their own PRs and forks to minimize conflicts. Each script should be
-run from the repository root.
-
-1. `.github/scripts/rename/definitions.sh`: This script will rename all
-   definitions, such as include guards, from `RIPPLE_XXX` and `RIPPLED_XXX` to
-   `XRPL_XXX`.
-2. `.github/scripts/rename/copyright.sh`: This script will remove superflous
-   copyright notices.
-3. `.github/scripts/rename/cmake.sh`: This script will rename all CMake files
-   from `RippleXXX.cmake` or `RippledXXX.cmake` to `XrplXXX.cmake`, and any
-   references to `ripple` and `rippled` (with or without capital letters) to
-   `xrpl` and `xrpld`, respectively. The name of the binary will remain as-is,
-   and will only be renamed to `xrpld` by a later script.
-4. `.github/scripts/rename/binary.sh`: This script will rename the binary from
-   `rippled` to `xrpld`, and create a symlink named `rippled` that points to the
-   `xrpld` binary.
-
-You can run all these scripts from the repository root as follows:
-
-```shell
-./.github/scripts/rename/definitions.sh .
-./.github/scripts/rename/copyright.sh .
-./.github/scripts/rename/cmake.sh .
-./.github/scripts/rename/binary.sh .

 ## Steps
 
 ### Set Up Conan
 
-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.

-unfamiliar with Conan, then please read [this crash course](./docs/build/conan.md) or the official
-[Getting Started][3] walkthrough.
+These instructions assume a basic familiarity with Conan and CMake.
 
-#### Default profile
+If you are unfamiliar with Conan, then please read [this crash course](./docs/build/conan.md) or the official [Getting Started][3] walkthrough.
 
-We recommend that you import the provided `conan/profiles/default` profile:
+You'll need at least one Conan profile:
 
-```bash
-conan config install conan/profiles/ -tf $(conan config home)/profiles/
+   ```
+   conan profile new default --detect
+   ```
+
+Update the compiler settings:
+
+   ```
+   conan profile update settings.compiler.cppstd=20 default
+   ```
+
+Configure Conan (1.x only) to use recipe revisions:
+
+   ```
+   conan config set general.revisions_enabled=1
+   ```
+
+**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:
+
+   ```
+   conan profile update settings.compiler.libcxx=libstdc++11 default
+   ```
+
+
+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
 ```
 
-You can check your Conan profile by running:
-
-```bash
-conan profile show
+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
 ```
 
-#### Custom profile
 
-If the default profile does not work for you and you do not yet have a Conan
-profile, you can create one by running:
+**Windows** developers may need to 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.
 
-```bash
-conan profile detect
+   Windows developers must also build `rippled` and its dependencies for the x64
+   architecture:
+
+   ```
+   conan profile update settings.arch=x86_64 default
+   ```
+
+### Multiple compilers
+
+When `/usr/bin/g++` exists on a platform, it is the default cpp compiler. This
+default works for some users.
+
+However, if this compiler cannot build rippled or its dependencies, then you can
+install another compiler and set Conan and CMake to use it.
+Update the `conf.tools.build:compiler_executables` setting in order to set the correct variables (`CMAKE_<LANG>_COMPILER`) in the
+generated CMake toolchain file.
+For example, on Ubuntu 20, you may have gcc at `/usr/bin/gcc` and g++ at `/usr/bin/g++`; if that is the case, you can select those compilers with:
+```
+conan profile update 'conf.tools.build:compiler_executables={"c": "/usr/bin/gcc", "cpp": "/usr/bin/g++"}' default
 ```
 
-You may need to make changes to the profile to suit your environment. You can
-refer to the provided `conan/profiles/default` profile for inspiration, and you
-may also need to apply the required [tweaks](#conan-profile-tweaks) to this
-default profile.
+Replace `/usr/bin/gcc` and `/usr/bin/g++` with paths to the desired compilers.
 
-### Patched recipes
+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.
+Replace `<path>` with paths to the desired compilers:
 
-The recipes in Conan Center occasionally need to be patched for compatibility
-with the latest version of `rippled`. We maintain a fork of the Conan Center
-[here](https://github.com/XRPLF/conan-center-index/) containing the patches.
+- `conan profile update env.CC=<path> default`
+- `conan profile update env.CXX=<path> default`
 
-To ensure our patched recipes are used, you must add our Conan remote at a
-higher index than the default Conan Center remote, so it is consulted first. You
-can do this by running:
+Export our [Conan recipe for Snappy](./external/snappy).
+It does not explicitly link the C++ standard library,
+which allows you to statically link it with GCC, if you want.
 
-```bash
-conan remote add --index 0 xrplf https://conan.ripplex.io
-```
+   ```
+   # Conan 1.x
+   conan export external/snappy snappy/1.1.10@
+   # Conan 2.x
+   conan export --version 1.1.10 external/snappy
+   ```
 
-Alternatively, you can pull the patched recipes into the repository and use them
-locally:
+Export our [Conan recipe for RocksDB](./external/rocksdb).
+It does not override paths to dependencies when building with Visual Studio.
 
-```bash
-cd external
-git init
-git remote add origin git@github.com:XRPLF/conan-center-index.git
-git sparse-checkout init
-git sparse-checkout set recipes/snappy
-git sparse-checkout add recipes/soci
-git fetch origin master
-git checkout master
-conan export --version 1.1.10 recipes/snappy/all
-conan export --version 4.0.3 recipes/soci/all
-rm -rf .git
-```
+   ```
+   # Conan 1.x
+   conan export external/rocksdb rocksdb/9.7.3@
+   # Conan 2.x
+   conan export --version 9.7.3 external/rocksdb
+   ```
 
-In the case we switch to a newer version of a dependency that still requires a
-patch, it will be necessary for you to pull in the changes and re-export the
-updated dependencies with the newer version. However, if we switch to a newer
-version that no longer requires a patch, no action is required on your part, as
-the new recipe will be automatically pulled from the official Conan Center.
+Export our [Conan recipe for SOCI](./external/soci).
+It patches their CMake to correctly import its dependencies.
 
-> [!NOTE]
-> You might need to add `--lockfile=""` to your `conan install` command
-> to avoid automatic use of the existing `conan.lock` file when you run `conan export` manually on your machine
+   ```
+   # Conan 1.x
+   conan export external/soci soci/4.0.3@
+   # Conan 2.x
+   conan export --version 4.0.3 external/soci
+   ```
 
-### Conan profile tweaks
+Export our [Conan recipe for NuDB](./external/nudb).
+It fixes some source files to add missing `#include`s.
 
-#### Missing compiler version
 
-If you see an error similar to the following after running `conan profile show`:
-
-```bash
-ERROR: Invalid setting '17' is not a valid 'settings.compiler.version' value.
-Possible values are ['5.0', '5.1', '6.0', '6.1', '7.0', '7.3', '8.0', '8.1',
-'9.0', '9.1', '10.0', '11.0', '12.0', '13', '13.0', '13.1', '14', '14.0', '15',
-'15.0', '16', '16.0']
-Read "http://docs.conan.io/2/knowledge/faq.html#error-invalid-setting"
-```
-
-you need to amend the list of compiler versions in
-`$(conan config home)/settings.yml`, by appending the required version number(s)
-to the `version` array specific for your compiler. For example:
-
-```yaml
-apple-clang:
-  version:
-    [
-      "5.0",
-      "5.1",
-      "6.0",
-      "6.1",
-      "7.0",
-      "7.3",
-      "8.0",
-      "8.1",
-      "9.0",
-      "9.1",
-      "10.0",
-      "11.0",
-      "12.0",
-      "13",
-      "13.0",
-      "13.1",
-      "14",
-      "14.0",
-      "15",
-      "15.0",
-      "16",
-      "16.0",
-      "17",
-      "17.0",
-    ]
-```
-
-#### Multiple compilers
-
-If you have multiple compilers installed, make sure to select the one to use in
-your default Conan configuration **before** running `conan profile detect`, by
-setting the `CC` and `CXX` environment variables.
-
-For example, if you are running MacOS and have [homebrew
-LLVM@18](https://formulae.brew.sh/formula/llvm@18), and want to use it as a
-compiler in the new Conan profile:
-
-```bash
-export CC=$(brew --prefix llvm@18)/bin/clang
-export CXX=$(brew --prefix llvm@18)/bin/clang++
-conan profile detect
-```
-
-You should also explicitly set the path to the compiler in the profile file,
-which helps to avoid errors when `CC` and/or `CXX` are set and disagree with the
-selected Conan profile. For example:
-
-```text
-[conf]
-tools.build:compiler_executables={'c':'/usr/bin/gcc','cpp':'/usr/bin/g++'}
-```
-
-#### Multiple profiles
-
-You can manage multiple Conan profiles in the directory
-`$(conan config home)/profiles`, for example renaming `default` to a different
-name and then creating a new `default` profile for a different compiler.
-
-#### Select language
-
-The default profile created by Conan will typically select different C++ dialect
-than C++20 used by this project. You should set `20` in the profile line
-starting with `compiler.cppstd=`. For example:
-
-```bash
-sed -i.bak -e 's|^compiler\.cppstd=.*$|compiler.cppstd=20|' $(conan config home)/profiles/default
-```
-
-#### Select standard library in Linux
-
-**Linux** developers will commonly have a default Conan [profile][] that
-compiles with GCC and links with libstdc++. If you are linking with libstdc++
-(see profile setting `compiler.libcxx`), then you will need to choose the
-`libstdc++11` ABI:
-
-```bash
-sed -i.bak -e 's|^compiler\.libcxx=.*$|compiler.libcxx=libstdc++11|' $(conan config home)/profiles/default
-```
-
-#### Select architecture and runtime in Windows
-
-**Windows** developers may need to use the x64 native build tools. An easy way
-to do that is to run the shortcut "x64 Native Tools Command Prompt" for the
-version of Visual Studio that you have installed.
-
-Windows developers must also build `rippled` and its dependencies for the x64
-architecture:
-
-```bash
-sed -i.bak -e 's|^arch=.*$|arch=x86_64|' $(conan config home)/profiles/default
-```
-
-**Windows** developers also must select static runtime:
-
-```bash
-sed -i.bak -e 's|^compiler\.runtime=.*$|compiler.runtime=static|' $(conan config home)/profiles/default
-```
-
-#### Clang workaround for grpc
-
-If your compiler is clang, version 19 or later, or apple-clang, version 17 or
-later, you may encounter a compilation error while building the `grpc`
-dependency:
-
-```text
-In file included from .../lib/promise/try_seq.h:26:
-.../lib/promise/detail/basic_seq.h:499:38: error: a template argument list is expected after a name prefixed by the template keyword [-Wmissing-template-arg-list-after-template-kw]

-
-The workaround for this error is to add two lines to profile:
-
-```text
-[conf]
-tools.build:cxxflags=['-Wno-missing-template-arg-list-after-template-kw']
-```
-
-#### Workaround for gcc 12
-
-If your compiler is gcc, version 12, and you have enabled `werr` option, you may
-encounter a compilation error such as:
-
-```text

-The `conan.lock` file in the repository contains a "snapshot" of the current dependencies.
-It is implicitly used when running `conan` commands, you don't need to specify it.
-
-You have to update this file every time you add a new dependency or change a revision or version of an existing dependency.
-
-> [!NOTE]
-> Conan uses local cache by default when creating a lockfile.
->
-> To ensure, that lockfile creation works the same way on all developer machines, you should clear the local cache before creating a new lockfile.
-
-To create a new lockfile, run the following commands in the repository root:
-
-```bash
-conan remove '*' --confirm
-rm conan.lock
-# This ensure that xrplf remote is the first to be consulted
-conan remote add --force --index 0 xrplf https://conan.ripplex.io
-conan lock create . -o '&:jemalloc=True' -o '&:rocksdb=True'

 [Unity builds][5] may be faster for the first build
 (at the cost of much more memory) since they concatenate sources into fewer
 translation units. Non-unity builds may be faster for incremental builds,
 and can be helpful for detecting `#include` omissions.

 ## Troubleshooting

 ### Conan
 
 After any updates or changes to dependencies, you may need to do the following:
 
 1. Remove your build directory.
-2. Remove individual libraries from the Conan cache, e.g.
-
-   ```bash
-   conan remove 'grpc/*'
+2. Remove the Conan cache:
    ```
-
-   **or**
-
-   Remove all libraries from Conan cache:
-
-   ```bash
-   conan remove '*'
+   rm -rf ~/.conan/data
    ```
+4. Re-run [conan install](#build-and-test).
 
-3. Re-run [conan export](#patched-recipes) if needed.
-4. [Regenerate lockfile](#conan-lockfile).
-5. Re-run [conan install](#build-and-test).

+### no std::result_of
+
+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.
+
+```

+
+
+### call to 'async_teardown' is ambiguous
+
+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][7]. You can workaround it by adding this preprocessor definition:
+
+```
+conan profile update 'env.CXXFLAGS="-DBOOST_ASIO_DISABLE_CONCEPTS"' default

+### recompile with -fPIC
+
+If you get a linker error suggesting that you recompile Boost with
+position-independent code, such as:
+
+```
+/usr/bin/ld.gold: error: /home/username/.conan/data/boost/1.77.0/_/_/package/.../lib/libboost_container.a(alloc_lib.o):
+  requires unsupported dynamic reloc 11; recompile with -fPIC
+```
+
+Conan most likely downloaded a bad binary distribution of the dependency.
+This seems to be a [bug][1] in Conan just for Boost 1.77.0 compiled with GCC
+for Linux. The solution is to build the dependency locally by passing
+`--build boost` when calling `conan install`.
+
+```
+conan install --build boost ...
+```
+
+
 ## Add a Dependency
 
 If you want to experiment with a new package, follow these steps:
 
 1. Search for the package on [Conan Center](https://conan.io/center/).
 2. Modify [`conanfile.py`](./conanfile.py):
-   - Add a version of the package to the `requires` property.
-   - Change any default options for the package by adding them to the
-     `default_options` property (with syntax `'$package:$option': $value`).
+    - Add a version of the package to the `requires` property.
+    - Change any default options for the package by adding them to the
+    `default_options` property (with syntax `'$package:$option': $value`).
 3. Modify [`CMakeLists.txt`](./CMakeLists.txt):
-   - Add a call to `find_package($package REQUIRED)`.
-   - Link a library from the package to the target `ripple_libs`
-     (search for the existing call to `target_link_libraries(ripple_libs INTERFACE ...)`).
+    - Add a call to `find_package($package REQUIRED)`.
+    - Link a library from the package to the target `ripple_libs`
+    (search for the existing call to `target_link_libraries(ripple_libs INTERFACE ...)`).
 4. Start coding! Don't forget to include whatever headers you need from the package.

 ## Key Features of the XRP Ledger
 
 - **[Censorship-Resistant Transaction Processing][]:** No single party decides which transactions succeed or fail, and no one can "roll back" a transaction after it completes. As long as those who choose to participate in the network keep it healthy, they can settle transactions in seconds.
 - **[Fast, Efficient Consensus Algorithm][]:** The XRP Ledger's consensus algorithm settles transactions in 4 to 5 seconds, processing at a throughput of up to 1500 transactions per second. These properties put XRP at least an order of magnitude ahead of other top digital assets.
-- **[Finite XRP Supply][]:** When the XRP Ledger began, 100 billion XRP were created, and no more XRP will ever be created. The available supply of XRP decreases slowly over time as small amounts are destroyed to pay transaction fees.
-- **[Responsible Software Governance][]:** A team of full-time developers at Ripple & other organizations maintain and continually improve the XRP Ledger's underlying software with contributions from the open-source community. Ripple acts as a steward for the technology and an advocate for its interests.
+- **[Finite XRP Supply][]:** When the XRP Ledger began, 100 billion XRP were created, and no more XRP will ever be created. The available supply of XRP decreases slowly over time as small amounts are destroyed to pay transaction costs.
+- **[Responsible Software Governance][]:** A team of full-time, world-class developers at Ripple maintain and continually improve the XRP Ledger's underlying software with contributions from the open-source community. Ripple acts as a steward for the technology and an advocate for its interests, and builds constructive relationships with governments and financial institutions worldwide.
 - **[Secure, Adaptable Cryptography][]:** The XRP Ledger relies on industry standard digital signature systems like ECDSA (the same scheme used by Bitcoin) but also supports modern, efficient algorithms like Ed25519. The extensible nature of the XRP Ledger's software makes it possible to add and disable algorithms as the state of the art in cryptography advances.
-- **[Modern Features][]:** Features like Escrow, Checks, and Payment Channels support financial applications atop of the XRP Ledger. This toolbox of advanced features comes with safety features like a process for amending the network and separate checks against invariant constraints.
+- **[Modern Features for Smart Contracts][]:** Features like Escrow, Checks, and Payment Channels support cutting-edge financial applications including the [Interledger Protocol](https://interledger.org/). This toolbox of advanced features comes with safety features like a process for amending the network and separate checks against invariant constraints.
 - **[On-Ledger Decentralized Exchange][]:** In addition to all the features that make XRP useful on its own, the XRP Ledger also has a fully-functional accounting system for tracking and trading obligations denominated in any way users want, and an exchange built into the protocol. The XRP Ledger can settle long, cross-currency payment paths and exchanges of multiple currencies in atomic transactions, bridging gaps of trust with XRP.

+- Read [the levelization document](./Builds/levelization) to get an idea of the internal dependency graph.
 - In the big picture, the `main` function constructs an `ApplicationImp` object, which implements the `Application` virtual interface. Almost every component in the application takes an `Application&` parameter in its constructor, typically named `app` and stored as a member variable `app_`. This allows most components to depend on any other component.
