 - 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.

+#### Default profile
 
-You'll need at least one Conan profile:
+We recommend that you import the provided `conan/profiles/default` profile:
 
-   ```
-   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
+```bash
+conan config install conan/profiles/ -tf $(conan config home)/profiles/
 ```
 
-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
+You can check your Conan profile by running:
+
+```bash
+conan profile show
 ```
 
+#### Custom profile
 
-**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.
+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 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
+```bash
+conan profile detect
 ```
 
-Replace `/usr/bin/gcc` and `/usr/bin/g++` with paths to the desired compilers.
+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.
 
-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:
+### Patched recipes
 
-- `conan profile update env.CC=<path> default`
-- `conan profile update env.CXX=<path> default`
+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.
 
-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.
+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:
 
-   ```
-   # Conan 1.x
-   conan export external/snappy snappy/1.1.10@
-   # Conan 2.x
-   conan export --version 1.1.10 external/snappy
-   ```
+```bash
+conan remote add --index 0 xrplf https://conan.ripplex.io
+```
 
-Export our [Conan recipe for RocksDB](./external/rocksdb).
-It does not override paths to dependencies when building with Visual Studio.
+Alternatively, you can pull the patched recipes into the repository and use them
+locally:
 
-   ```
-   # Conan 1.x
-   conan export external/rocksdb rocksdb/6.29.5@
-   # Conan 2.x
-   conan export --version 6.29.5 external/rocksdb
-   ```
+```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
+```
 
-Export our [Conan recipe for SOCI](./external/soci).
-It patches their CMake to correctly import its dependencies.
+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.
 
-   ```
-   # Conan 1.x
-   conan export external/soci soci/4.0.3@
-   # Conan 2.x
-   conan export --version 4.0.3 external/soci
-   ```
+> [!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
 
-Export our [Conan recipe for NuDB](./external/nudb).
-It fixes some source files to add missing `#include`s.
+### Conan profile tweaks
 
+#### Missing compiler version
 
-   ```
-   # Conan 1.x
-   conan export external/nudb nudb/2.0.8@
-   # Conan 2.x
-   conan export --version 2.0.8 external/nudb
-   ```
+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'
+```
+

-```
-
-Conan most likely downloaded a bad binary distribution of the dependency.

 # The XRP Ledger
 
 The [XRP Ledger](https://xrpl.org/) is a decentralized cryptographic ledger powered by a network of peer-to-peer nodes. The XRP Ledger uses a novel Byzantine Fault Tolerant consensus algorithm to settle and record transactions in a secure distributed database without a central operator.
 
 ## XRP
-[XRP](https://xrpl.org/xrp.html) is a public, counterparty-free asset native to the XRP Ledger, and is designed to bridge the many different currencies in use worldwide. XRP is traded on the open-market and is available for anyone to access. The XRP Ledger was created in 2012 with a finite supply of 100 billion units of XRP.

XRP is traded on the open-market and is available for anyone to access. The XRP Ledger was created in 2012 with a finite supply of 100 billion units of XRP.
 
 ## rippled
+
 The server software that powers the XRP Ledger is called `rippled` and is available in this repository under the permissive [ISC open-source license](LICENSE.md). The `rippled` server software is written primarily in C++ and runs on a variety of platforms. The `rippled` server software can run in several modes depending on its [configuration](https://xrpl.org/rippled-server-modes.html).
 
 If you are interested in running an **API Server** (including a **Full History Server**), take a look at [Clio](https://github.com/XRPLF/clio). (rippled Reporting Mode has been replaced by Clio.)

 ## 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 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.

+- **[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.
 - **[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 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.
+- **[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.
 - **[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](.github/scripts/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.

+#                           Must be a power of 2 between 4096 and 32768. Default is 4096.
+#
+#                           This parameter controls the fundamental storage unit

+#                           depending on your storage hardware and filesystem:
+#
+#                           - 4096 bytes: Optimal for most standard SSDs and
+#                             traditional filesystems (ext4, NTFS, HFS+).
+#                             Provides good balance of performance and storage
+#                             efficiency. Recommended for most deployments.
+#                             Minimizes memory footprint and provides consistent
+#                             low-latency access patterns across diverse hardware.
+#
+#                           - 8192-16384 bytes: May improve performance on
+#                             high-end NVMe SSDs and copy-on-write filesystems
+#                             like ZFS or Btrfs that benefit from larger block
+#                             alignment. Can reduce metadata overhead for large
+#                             databases. Offers better sequential throughput and
+#                             reduced I/O operations at the cost of higher memory
+#                             usage per operation.
+#
+#                           - 32768 bytes (32K): Maximum supported block size
+#                             for high-performance scenarios with very fast
+#                             storage. May increase memory usage and reduce
+#                             efficiency for smaller databases. Best suited for
+#                             enterprise environments with abundant RAM.
+#
+#                           Performance testing is recommended before deploying
