 Levelization is the term used to describe efforts to prevent rippled from

+- **libxrpl** (`src/libxrpl`, `include/xrpl`): Reusable library modules with public interfaces
+- **xrpld** (`src/xrpld`): Application-specific implementation code

 Unfortunately, over time, enforcement of levelization has been
 inconsistent, so the current state of the code doesn't necessarily
 reflect these rules. Whenever possible, developers should refactor any
 levelization violations they find (by moving files or individual
 classes). At the very least, don't make things worse.

-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 lockfile
+
+To achieve reproducible dependencies, we use a [Conan lockfile](https://docs.conan.io/2/tutorial/versioning/lockfiles.html).
+
+The `conan.lock` file in the repository contains a "snapshot" of the current
+dependencies. It is implicitly used when running `conan` commands, so 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.
+
+To update a lockfile, run from the repository root: `./conan/lockfile/regenerate.sh`

+
+## Building with Sanitizers
+
+### Summary
+
+Follow the same instructions as mentioned in [BUILD.md](../../BUILD.md) but with the following changes:
+
+1. Make sure you have a clean build directory.
+2. Set the `SANITIZERS` environment variable before calling conan install and cmake. Only set it once. Make sure both conan and cmake read the same values.
+   Example: `export SANITIZERS=Address,UndefinedBehavior`
+3. Optionally use `--profile:all sanitizers` with Conan to build dependencies with sanitizer instrumentation.
+4. Set `ASAN_OPTIONS`, `LSAN_OPTIONS`, `UBSAN_OPTIONS` and `TSAN_OPTIONS` environment variables to configure sanitizer behavior when running executables.
+
+---
+
+### Build steps:
+
+```bash
+cd /path/to/rippled
+rm -rf .build
+mkdir .build
+cd .build
+```
+
+#### Install dependencies
+
+The `SANITIZERS` environment variable is used by both Conan and CMake.
+
+```bash
+export SANITIZERS=Address,UndefinedBehavior
+# Standard build (without instrumenting dependencies)
+conan install .. --output-folder . --build missing --settings build_type=Debug
+
+# Or with sanitizer-instrumented dependencies (takes longer but fewer false positives)
+conan install .. --output-folder . --profile:all sanitizers --build missing --settings build_type=Debug
+```
+
+**Note:** Do not mix Address and Thread sanitizers - they are incompatible.
+
+Since you already set the `SANITIZERS` environment variable when running Conan, same values will be read for the next part.
+
+#### Call CMake
+
+```bash
+cmake .. -G Ninja \
+    -DCMAKE_TOOLCHAIN_FILE:FILEPATH=build/generators/conan_toolchain.cmake \
+    -DCMAKE_BUILD_TYPE=Debug \
+    -Dtests=ON -Dxrpld=ON
+```
+
+#### Build
+
+```bash
+cmake --build . --parallel 4
+```
+
+## Running Tests with Sanitizers
+
+### AddressSanitizer (ASan)
+
+**IMPORTANT**: ASan with Boost produces many false positives. Use these options:
+
+```bash
+export ASAN_OPTIONS="detect_container_overflow=0 suppressions=path/to/asan.supp halt_on_error=0 log_path=asan.log"
+export UBSAN_OPTIONS="suppressions=path/to/ubsan.supp print_stacktrace=1 halt_on_error=0 log_path=ubsan.log"
+export LSAN_OPTIONS="suppressions=path/to/lsan.supp halt_on_error=0 log_path=lsan.log"
+
+# Run tests
+./rippled --unittest --unittest-jobs=5
+```
+
+**Why `detect_container_overflow=0`?**
+
+- Boost intrusive containers (used in `aged_unordered_container`) trigger false positives
+- Boost context switching (used in `Workers.cpp`) confuses ASan's stack tracking
+- Since we usually don't build boost(because we don't want to instrument boost and detect issues in boost code) with asan but use boost containers in ASAN instrumented rippled code, it generates false positives.
+- See: https://github.com/google/sanitizers/wiki/AddressSanitizerContainerOverflow
+
+### ThreadSanitizer (TSan) + UndefinedBehaviorSanitizer (UBSan)
+
+```bash
+export TSAN_OPTIONS="suppressions=path/to/tsan.supp halt_on_error=0 log_path=tsan.log"
+
+# Run tests
+./rippled --unittest --unittest-jobs=5
+```
+
+### LeakSanitizer (LSan)
+
+LSan is automatically enabled with ASan. To disable it:
+
+```bash
+export ASAN_OPTIONS="detect_leaks=0"
+```
+
+## Suppression Files
+
+### `asan.supp`
+
+- **Purpose**: Suppress AddressSanitizer (ASan) errors only
+- **Format**: `interceptor_name:<pattern>` where pattern matches file names. Supported suppression types are:
+  - interceptor_name
+  - interceptor_via_fun
+  - interceptor_via_lib
+  - odr_violation
+- **More info**: [AddressSanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizer)
+- **Note**: Cannot suppress stack-buffer-overflow, container-overflow, etc.
+
+### `lsan.supp`
+
+- **Purpose**: Suppress LeakSanitizer (LSan) errors only
+- **Format**: `leak:<pattern>` where pattern matches function/file names
+- **More info**: [LeakSanitizer](https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer)
+
+### `ubsan.supp`
+
+- **Purpose**: Suppress UndefinedBehaviorSanitizer errors
+- **Format**: `<error_type>:<pattern>` (e.g., `unsigned-integer-overflow:protobuf`)
+- **Covers**: Intentional overflows in sanitizers/suppressions libraries (protobuf, gRPC, stdlib)
+
+### `tsan.supp`
+
+- **Purpose**: Suppress ThreadSanitizer data race warnings
+- **Format**: `race:<pattern>` where pattern matches function/file names
+- **More info**: [ThreadSanitizerSuppressions](https://github.com/google/sanitizers/wiki/ThreadSanitizerSuppressions)
+
+### `sanitizer-ignorelist.txt`
+
+- **Purpose**: Compile-time ignorelist for all sanitizers
+- **Usage**: Passed via `-fsanitize-ignorelist=absolute/path/to/sanitizer-ignorelist.txt`
+- **Format**: `<level>:<pattern>` (e.g., `src:Workers.cpp`)
+
+## Troubleshooting
+
+### "ASan is ignoring requested \_\_asan_handle_no_return" warnings
+
+These warnings appear when using Boost context switching and are harmless. They indicate potential false positives.
+
+### Sanitizer Mismatch Errors
+
+If you see undefined symbols like `___tsan_atomic_load` when building with ASan:
+
+**Problem**: Dependencies were built with a different sanitizer than the main project.
+
+**Solution**: Rebuild everything with the same sanitizer:
+
+```bash
+rm -rf .build
+# Then follow the build instructions above
+```
+
+Then review the log files: `asan.log.*`, `ubsan.log.*`, `tsan.log.*`

-This project provides performant, portable 32-bit & 64-bit implementations. All implementations are 
-of course constant time in regard to secret data.
-
-#### Performance
-
-SSE2 code and benches have not been updated yet. I will do those next.
-
-Compilers versions are gcc 4.6.3, icc 13.1.1, clang 3.4-1~exp1.
-
-Batch verification time (in parentheses) is the average time per 1 verification in a batch of 64 signatures. Counts are in thousands of cycles.
-
-Note that SSE2 performance may be less impressive on AMD & older CPUs with slower SSE ops!
-
-Visual Studio performance for `ge25519_scalarmult_base_niels` will lag behind a bit until optimized assembler versions of `ge25519_scalarmult_base_choose_niels`
-are made.

-
-#### Compilation
-
-No configuration is needed **if you are compiling against OpenSSL**. 
-
-##### Hash Options
-
-If you are not compiling aginst OpenSSL, you will need a hash function.
-
-To use a simple/**slow** implementation of SHA-512, use `-DED25519_REFHASH` when compiling `ed25519.c`. 
-This should never be used except to verify the code works when OpenSSL is not available.
-
-To use a custom hash function, use `-DED25519_CUSTOMHASH` when compiling `ed25519.c` and put your 
-custom hash implementation in ed25519-hash-custom.h. The hash must have a 512bit digest and implement
-
-	struct ed25519_hash_context;
-
-	void ed25519_hash_init(ed25519_hash_context *ctx);
-	void ed25519_hash_update(ed25519_hash_context *ctx, const uint8_t *in, size_t inlen);
-	void ed25519_hash_final(ed25519_hash_context *ctx, uint8_t *hash);
-	void ed25519_hash(uint8_t *hash, const uint8_t *in, size_t inlen);
-
-##### Random Options
-
-If you are not compiling aginst OpenSSL, you will need a random function for batch verification.
-
-To use a custom random function, use `-DED25519_CUSTOMRANDOM` when compiling `ed25519.c` and put your 
-custom hash implementation in ed25519-randombytes-custom.h. The random function must implement:
-
-	void ED25519_FN(ed25519_randombytes_unsafe) (void *p, size_t len);
-
-Use `-DED25519_TEST` when compiling `ed25519.c` to use a deterministically seeded, non-thread safe CSPRNG 
-variant of Bob Jenkins [ISAAC](http://en.wikipedia.org/wiki/ISAAC_%28cipher%29)
-
-##### Minor options
-
-Use `-DED25519_INLINE_ASM` to disable the use of custom assembler routines and instead rely on portable C.
-
-Use `-DED25519_FORCE_32BIT` to force the use of 32 bit routines even when compiling for 64 bit.
-
-##### 32-bit
-
-	gcc ed25519.c -m32 -O3 -c
-
-##### 64-bit
-
-	gcc ed25519.c -m64 -O3 -c
-
-##### SSE2
-
-	gcc ed25519.c -m32 -O3 -c -DED25519_SSE2 -msse2
-	gcc ed25519.c -m64 -O3 -c -DED25519_SSE2
-
-clang and icc are also supported
-
-
-#### Usage
-
-To use the code, link against `ed25519.o -mbits` and:
-
-	#include "ed25519.h"
-
-Add `-lssl -lcrypto` when using OpenSSL (Some systems don't need -lcrypto? It might be trial and error).
-
-To generate a private key, simply generate 32 bytes from a secure
-cryptographic source:
-
-	ed25519_secret_key sk;
-	randombytes(sk, sizeof(ed25519_secret_key));
-
-To generate a public key:
-
-	ed25519_public_key pk;
-	ed25519_publickey(sk, pk);
-
-To sign a message:
-
-	ed25519_signature sig;
-	ed25519_sign(message, message_len, sk, pk, signature);
-
-To verify a signature:
-
-	int valid = ed25519_sign_open(message, message_len, pk, signature) == 0;
-
-To batch verify signatures:
-
-	const unsigned char *mp[num] = {message1, message2..}
-	size_t ml[num] = {message_len1, message_len2..}
-	const unsigned char *pkp[num] = {pk1, pk2..}
-	const unsigned char *sigp[num] = {signature1, signature2..}
-	int valid[num]
-
-	/* valid[i] will be set to 1 if the individual signature was valid, 0 otherwise */
-	int all_valid = ed25519_sign_open_batch(mp, ml, pkp, sigp, num, valid) == 0;
-
-**Note**: Batch verification uses `ed25519_randombytes_unsafe`, implemented in 
-`ed25519-randombytes.h`, to generate random scalars for the verification code. 
-The default implementation now uses OpenSSLs `RAND_bytes`.
-
-Unlike the [SUPERCOP](http://bench.cr.yp.to/supercop.html) version, signatures are
-not appended to messages, and there is no need for padding in front of messages. 
-Additionally, the secret key does not contain a copy of the public key, so it is 
-32 bytes instead of 64 bytes, and the public key must be provided to the signing
-function.
-
-##### Curve25519
-
-Curve25519 public keys can be generated thanks to 
-[Adam Langley](http://www.imperialviolet.org/2013/05/10/fastercurve25519.html) 
-leveraging Ed25519's precomputed basepoint scalar multiplication.
-
-	curved25519_key sk, pk;
-	randombytes(sk, sizeof(curved25519_key));
-	curved25519_scalarmult_basepoint(pk, sk);
-
-Note the name is curved25519, a combination of curve and ed25519, to prevent 
-name clashes. Performance is slightly faster than short message ed25519
-signing due to both using the same code for the scalar multiply.
-
-#### Testing
-
-Fuzzing against reference implemenations is now available. See [fuzz/README](fuzz/README.md).
-
-Building `ed25519.c` with `-DED25519_TEST` and linking with `test.c` will run basic sanity tests
-and benchmark each function. `test-batch.c` has been incorporated in to `test.c`.
-
-`test-internals.c` is standalone and built the same way as `ed25519.c`. It tests the math primitives
-with extreme values to ensure they function correctly. SSE2 is now supported.

-This code fuzzes ed25519-donna (and optionally ed25519-donna-sse2) against the ref10 implementations of
-[curve25519](https://github.com/floodyberry/supercop/tree/master/crypto_scalarmult/curve25519/ref10) and 
-[ed25519](https://github.com/floodyberry/supercop/tree/master/crypto_sign/ed25519/ref10).

-# Building
-
-## *nix + PHP
-
-`php build-nix.php (required parameters) (optional parameters)`
-
-Required parameters:
-
-* `--function=[curve25519,ed25519]`
-* `--bits=[32,64]`
-
-Optional parameters:
-
-* `--with-sse2`
-
-    Also fuzz against ed25519-donna-sse2
-* `--with-openssl`
-
-    Build with OpenSSL's SHA-512.
-
-    Default: Reference SHA-512 implementation (slow!)
-
-* `--compiler=[gcc,clang,icc]`
-
-    Default: gcc
-
-* `--no-asm`
-
-    Do not use platform specific assembler
-
-
-example:
-    
-    php build-nix.php --bits=64 --function=ed25519 --with-sse2 --compiler=icc 
-
-## Windows
-
-Create a project with access to the ed25519 files.
-
-If you are not using OpenSSL, add the `ED25519_REFHASH` define to the projects 
-"Properties/Preprocessor/Preprocessor Definitions" option
-
-Add the following files to the project:
-
-* `fuzz/curve25519-ref10.c`
-* `fuzz/ed25519-ref10.c`
-* `fuzz/ed25519-donna.c`
-* `fuzz/ed25519-donna-sse2.c` (optional)
-* `fuzz-[curve25519/ed25519].c` (depending on which you want to fuzz)
-
-If you are also fuzzing against ed25519-donna-sse2, add the `ED25519_SSE2` define for `fuzz-[curve25519/ed25519].c` under 
-its "Properties/Preprocessor/Preprocessor Definitions" option.
-
-# Running
-
-If everything agrees, the program will only output occasional status dots (every 0x1000 passes) 
-and a 64bit progress count (every 0x20000 passes):

-If any of the implementations do not agree with the ref10 implementation, the program will dump
-the random data that was used, the data generated by the ref10 implementation, and diffs of the

-# Changelog
-
-All notable changes to this project will be documented in this file.
-
-The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
-and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
-
-## [0.6.0] - 2024-11-04
-
-#### Added
- - New module `musig` implements the MuSig2 multisignature scheme according to the [BIP 327 specification](https://github.com/bitcoin/bips/blob/master/bip-0327.mediawiki). See:
-   - Header file `include/secp256k1_musig.h` which defines the new API.
-   - Document `doc/musig.md` for further notes on API usage.
-   - Usage example `examples/musig.c`.
- - New CMake variable `SECP256K1_APPEND_LDFLAGS` for appending linker flags to the build command.
-
-#### Changed
- - API functions now use a significantly more robust method to clear secrets from the stack before returning. However, secret clearing remains a best-effort security measure and cannot guarantee complete removal.
- - Any type `secp256k1_foo` can now be forward-declared using `typedef struct secp256k1_foo secp256k1_foo;` (or also `struct secp256k1_foo;` in C++).
- - Organized CMake build artifacts into dedicated directories (`bin/` for executables, `lib/` for libraries) to improve build output structure and Windows shared library compatibility.
-
-#### Removed
- - Removed the `secp256k1_scratch_space` struct and its associated functions `secp256k1_scratch_space_create` and `secp256k1_scratch_space_destroy` because the scratch space was unused in the API.
-
-#### ABI Compatibility
-The symbols `secp256k1_scratch_space_create` and `secp256k1_scratch_space_destroy` were removed.
-Otherwise, the library maintains backward compatibility with versions 0.3.x through 0.5.x.
-
-## [0.5.1] - 2024-08-01
-
-#### Added
- - Added usage example for an ElligatorSwift key exchange.
-
-#### Changed
- - The default size of the precomputed table for signing was changed from 22 KiB to 86 KiB. The size can be changed with the configure option `--ecmult-gen-kb` (`SECP256K1_ECMULT_GEN_KB` for CMake).
- - "auto" is no longer an accepted value for the `--with-ecmult-window` and `--with-ecmult-gen-kb` configure options (this also applies to  `SECP256K1_ECMULT_WINDOW_SIZE` and `SECP256K1_ECMULT_GEN_KB` in CMake). To achieve the same configuration as previously provided by the "auto" value, omit setting the configure option explicitly.
-
-#### Fixed
- - Fixed compilation when the extrakeys module is disabled.
-
-#### ABI Compatibility
-The ABI is backward compatible with versions 0.5.0, 0.4.x and 0.3.x.
-
-## [0.5.0] - 2024-05-06
-
-#### Added
- - New function `secp256k1_ec_pubkey_sort` that sorts public keys using lexicographic (of compressed serialization) order.
-
-#### Changed
- - The implementation of the point multiplication algorithm used for signing and public key generation was changed, resulting in improved performance for those operations.
-   - The related configure option `--ecmult-gen-precision` was replaced with `--ecmult-gen-kb` (`SECP256K1_ECMULT_GEN_KB` for CMake).
-   - This changes the supported precomputed table sizes for these operations. The new supported sizes are 2 KiB, 22 KiB, or 86 KiB (while the old supported sizes were 32 KiB, 64 KiB, or 512 KiB).
-
-#### ABI Compatibility
-The ABI is backward compatible with versions 0.4.x and 0.3.x.
-
-## [0.4.1] - 2023-12-21
-
-#### Changed
- - The point multiplication algorithm used for ECDH operations (module `ecdh`) was replaced with a slightly faster one.
- - Optional handwritten x86_64 assembly for field operations was removed because modern C compilers are able to output more efficient assembly. This change results in a significant speedup of some library functions when handwritten x86_64 assembly is enabled (`--with-asm=x86_64` in GNU Autotools, `-DSECP256K1_ASM=x86_64` in CMake), which is the default on x86_64. Benchmarks with GCC 10.5.0 show a 10% speedup for `secp256k1_ecdsa_verify` and `secp256k1_schnorrsig_verify`.
-
-#### ABI Compatibility
-The ABI is backward compatible with versions 0.4.0 and 0.3.x.
-
-## [0.4.0] - 2023-09-04
-
-#### Added
- - New module `ellswift` implements ElligatorSwift encoding for public keys and x-only Diffie-Hellman key exchange for them.
-   ElligatorSwift permits representing secp256k1 public keys as 64-byte arrays which cannot be distinguished from uniformly random. See:
-   - Header file `include/secp256k1_ellswift.h` which defines the new API.
-   - Document `doc/ellswift.md` which explains the mathematical background of the scheme.
-   - The [paper](https://eprint.iacr.org/2022/759) on which the scheme is based.
- - We now test the library with unreleased development snapshots of GCC and Clang. This gives us an early chance to catch miscompilations and constant-time issues introduced by the compiler (such as those that led to the previous two releases).
-
-#### Fixed
- - Fixed symbol visibility in Windows DLL builds, where three internal library symbols were wrongly exported.
-
-#### Changed
- - When consuming libsecp256k1 as a static library on Windows, the user must now define the `SECP256K1_STATIC` macro before including `secp256k1.h`.
-
-#### ABI Compatibility
-This release is backward compatible with the ABI of 0.3.0, 0.3.1, and 0.3.2. Symbol visibility is now believed to be handled properly on supported platforms and is now considered to be part of the ABI. Please report any improperly exported symbols as a bug.
-
-## [0.3.2] - 2023-05-13
-We strongly recommend updating to 0.3.2 if you use or plan to use GCC >=13 to compile libsecp256k1. When in doubt, check the GCC version using `gcc -v`.
-
-#### Security
- - Module `ecdh`: Fix "constant-timeness" issue with GCC 13.1 (and potentially future versions of GCC) that could leave applications using libsecp256k1's ECDH module vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow during ECDH computations when libsecp256k1 is compiled with GCC 13.1.
-
-#### Fixed
- - Fixed an old bug that permitted compilers to potentially output bad assembly code on x86_64. In theory, it could lead to a crash or a read of unrelated memory, but this has never been observed on any compilers so far.
-
-#### Changed
- - Various improvements and changes to CMake builds. CMake builds remain experimental.
-   - Made API versioning consistent with GNU Autotools builds.
-   - Switched to `BUILD_SHARED_LIBS` variable for controlling whether to build a static or a shared library.
-   - Added `SECP256K1_INSTALL` variable for the controlling whether to install the build artefacts.
- - Renamed asm build option `arm` to `arm32`. Use `--with-asm=arm32` instead of `--with-asm=arm` (GNU Autotools), and `-DSECP256K1_ASM=arm32` instead of `-DSECP256K1_ASM=arm` (CMake).
-
-#### ABI Compatibility
-The ABI is compatible with versions 0.3.0 and 0.3.1.
-
-## [0.3.1] - 2023-04-10
-We strongly recommend updating to 0.3.1 if you use or plan to use Clang >=14 to compile libsecp256k1, e.g., Xcode >=14 on macOS has Clang >=14. When in doubt, check the Clang version using `clang -v`.
-
-#### Security
- - Fix "constant-timeness" issue with Clang >=14 that could leave applications using libsecp256k1 vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow and secret-dependent memory accesses in conditional moves of memory objects when libsecp256k1 is compiled with Clang >=14.
-
-#### Added
-  - Added tests against [Project Wycheproof's](https://github.com/google/wycheproof/) set of ECDSA test vectors (Bitcoin "low-S" variant), a fixed set of test cases designed to trigger various edge cases.
-
-#### Changed
- - Increased minimum required CMake version to 3.13. CMake builds remain experimental.
-
-#### ABI Compatibility
-The ABI is compatible with version 0.3.0.
-
-## [0.3.0] - 2023-03-08
-
-#### Added
- - Added experimental support for CMake builds. Traditional GNU Autotools builds (`./configure` and `make`) remain fully supported.
- - Usage examples: Added a recommended method for securely clearing sensitive data, e.g., secret keys, from memory.
- - Tests: Added a new test binary `noverify_tests`. This binary runs the tests without some additional checks present in the ordinary `tests` binary and is thereby closer to production binaries. The `noverify_tests` binary is automatically run as part of the `make check` target.
-
-#### Fixed
- - Fixed declarations of API variables for MSVC (`__declspec(dllimport)`). This fixes MSVC builds of programs which link against a libsecp256k1 DLL dynamically and use API variables (and not only API functions). Unfortunately, the MSVC linker now will emit warning `LNK4217` when trying to link against libsecp256k1 statically. Pass `/ignore:4217` to the linker to suppress this warning.
-
-#### Changed
- - Forbade cloning or destroying `secp256k1_context_static`. Create a new context instead of cloning the static context. (If this change breaks your code, your code is probably wrong.)
- - Forbade randomizing (copies of) `secp256k1_context_static`. Randomizing a copy of `secp256k1_context_static` did not have any effect and did not provide defense-in-depth protection against side-channel attacks. Create a new context if you want to benefit from randomization.
-
-#### Removed
- - Removed the configuration header `src/libsecp256k1-config.h`. We recommend passing flags to `./configure` or `cmake` to set configuration options (see `./configure --help` or `cmake -LH`). If you cannot or do not want to use one of the supported build systems, pass configuration flags such as `-DSECP256K1_ENABLE_MODULE_SCHNORRSIG` manually to the compiler (see the file `configure.ac` for supported flags).
-
-#### ABI Compatibility
-Due to changes in the API regarding `secp256k1_context_static` described above, the ABI is *not* compatible with previous versions.
-
-## [0.2.0] - 2022-12-12
-
-#### Added
- - Added usage examples for common use cases in a new `examples/` directory.
- - Added `secp256k1_selftest`, to be used in conjunction with `secp256k1_context_static`.
- - Added support for 128-bit wide multiplication on MSVC for x86_64 and arm64, giving roughly a 20% speedup on those platforms.
-
-#### Changed
- - Enabled modules `schnorrsig`, `extrakeys` and `ecdh` by default in `./configure`.
- - The `secp256k1_nonce_function_rfc6979` nonce function, used by default by `secp256k1_ecdsa_sign`, now reduces the message hash modulo the group order to match the specification. This only affects improper use of ECDSA signing API.
-
-#### Deprecated
- - Deprecated context flags `SECP256K1_CONTEXT_VERIFY` and `SECP256K1_CONTEXT_SIGN`. Use `SECP256K1_CONTEXT_NONE` instead.
- - Renamed `secp256k1_context_no_precomp` to `secp256k1_context_static`.
- - Module `schnorrsig`: renamed `secp256k1_schnorrsig_sign` to `secp256k1_schnorrsig_sign32`.
-
-#### ABI Compatibility
-Since this is the first release, we do not compare application binary interfaces.
-However, there are earlier unreleased versions of libsecp256k1 that are *not* ABI compatible with this version.
-
-## [0.1.0] - 2013-03-05 to 2021-12-25
-
-This version was in fact never released.
-The number was given by the build system since the introduction of autotools in Jan 2014 (ea0fe5a5bf0c04f9cc955b2966b614f5f378c6f6).
-Therefore, this version number does not uniquely identify a set of source files.

-# Contributing to libsecp256k1
-
-## Scope
-
-libsecp256k1 is a library for elliptic curve cryptography on the curve secp256k1, not a general-purpose cryptography library.
-The library primarily serves the needs of the Bitcoin Core project but provides additional functionality for the benefit of the wider Bitcoin ecosystem.
-
-## Adding new functionality or modules
-
-The libsecp256k1 project welcomes contributions in the form of new functionality or modules, provided they are within the project's scope.
-
-It is the responsibility of the contributors to convince the maintainers that the proposed functionality is within the project's scope, high-quality and maintainable.
-Contributors are recommended to provide the following in addition to the new code:
-
-* **Specification:**
-    A specification can help significantly in reviewing the new code as it provides documentation and context.
-    It may justify various design decisions, give a motivation and outline security goals.
-    If the specification contains pseudocode, a reference implementation or test vectors, these can be used to compare with the proposed libsecp256k1 code.
-* **Security Arguments:**
-    In addition to a defining the security goals, it should be argued that the new functionality meets these goals.
-    Depending on the nature of the new functionality, a wide range of security arguments are acceptable, ranging from being "obviously secure" to rigorous proofs of security.
-* **Relevance Arguments:**
-    The relevance of the new functionality for the Bitcoin ecosystem should be argued by outlining clear use cases.
-
-These are not the only factors taken into account when considering to add new functionality.
-The proposed new libsecp256k1 code must be of high quality, including API documentation and tests, as well as featuring a misuse-resistant API design.
-
-We recommend reaching out to other contributors (see [Communication Channels](#communication-channels)) and get feedback before implementing new functionality.
-
-## Communication channels
-
-Most communication about libsecp256k1 occurs on the GitHub repository: in issues, pull request or on the discussion board.
-
-Additionally, there is an IRC channel dedicated to libsecp256k1, with biweekly meetings (see channel topic).
-The channel is `#secp256k1` on Libera Chat.
-The easiest way to participate on IRC is with the web client, [web.libera.chat](https://web.libera.chat/#secp256k1).
-Chat history logs can be found at https://gnusha.org/secp256k1/.
-
-## Contributor workflow & peer review
-
-The Contributor Workflow & Peer Review in libsecp256k1 are similar to Bitcoin Core's workflow and review processes described in its [CONTRIBUTING.md](https://github.com/bitcoin/bitcoin/blob/master/CONTRIBUTING.md).
-
-### Coding conventions
-
-In addition, libsecp256k1 tries to maintain the following coding conventions:
-
-* No runtime heap allocation (e.g., no `malloc`) unless explicitly requested by the caller (via `secp256k1_context_create` or `secp256k1_scratch_space_create`, for example). Moreover, it should be possible to use the library without any heap allocations.
-* The tests should cover all lines and branches of the library (see [Test coverage](#coverage)).
-* Operations involving secret data should be tested for being constant time with respect to the secrets (see [src/ctime_tests.c](src/ctime_tests.c)).
-* Local variables containing secret data should be cleared explicitly to try to delete secrets from memory.
-* Use `secp256k1_memcmp_var` instead of `memcmp` (see [#823](https://github.com/bitcoin-core/secp256k1/issues/823)).
-* As a rule of thumb, the default values for configuration options should target standard desktop machines and align with Bitcoin Core's defaults, and the tests should mostly exercise the default configuration (see [#1549](https://github.com/bitcoin-core/secp256k1/issues/1549#issuecomment-2200559257)).
-
-#### Style conventions
-
-* Commits should be atomic and diffs should be easy to read. For this reason, do not mix any formatting fixes or code moves with actual code changes. Make sure each individual commit is hygienic: that it builds successfully on its own without warnings, errors, regressions, or test failures.
-* New code should adhere to the style of existing, in particular surrounding, code. Other than that, we do not enforce strict rules for code formatting.
-* The code conforms to C89. Most notably, that means that only `/* ... */` comments are allowed (no `//` line comments). Moreover, any declarations in a `{ ... }` block (e.g., a function) must appear at the beginning of the block before any statements. When you would like to declare a variable in the middle of a block, you can open a new block:
-    ```C
-    void secp256k_foo(void) {
-        unsigned int x;              /* declaration */
-        int y = 2*x;                 /* declaration */
-        x = 17;                      /* statement */
-        {
-            int a, b;                /* declaration */
-            a = x + y;               /* statement */
-            secp256k_bar(x, &b);     /* statement */
-        }
-    }
-    ```
-* Use `unsigned int` instead of just `unsigned`.
-* Use `void *ptr` instead of `void* ptr`.
-* Arguments of the publicly-facing API must have a specific order defined in [include/secp256k1.h](include/secp256k1.h).
-* User-facing comment lines in headers should be limited to 80 chars if possible.
-* All identifiers in file scope should start with `secp256k1_`.
-* Avoid trailing whitespace.
-
-### Tests
-
-#### Coverage
-
-This library aims to have full coverage of reachable lines and branches.
-
-To create a test coverage report, configure with `--enable-coverage` (use of GCC is necessary):
-
-    $ ./configure --enable-coverage
-
-Run the tests:
-
-    $ make check
-
-To create a report, `gcovr` is recommended, as it includes branch coverage reporting:
-
-    $ gcovr --exclude 'src/bench*' --print-summary
-
-To create a HTML report with coloured and annotated source code:
-
-    $ mkdir -p coverage
-    $ gcovr --exclude 'src/bench*' --html --html-details -o coverage/coverage.html
-
-#### Exhaustive tests
-
-There are tests of several functions in which a small group replaces secp256k1.
-These tests are *exhaustive* since they provide all elements and scalars of the small group as input arguments (see [src/tests_exhaustive.c](src/tests_exhaustive.c)).
-
-### Benchmarks
-
-See `src/bench*.c` for examples of benchmarks.

-
-High-performance high-assurance C library for digital signatures and other cryptographic primitives on the secp256k1 elliptic curve.
-
-This library is intended to be the highest quality publicly available library for cryptography on the secp256k1 curve. However, the primary focus of its development has been for usage in the Bitcoin system and usage unlike Bitcoin's may be less well tested, verified, or suffer from a less well thought out interface. Correct usage requires some care and consideration that the library is fit for your application's purpose.
-
-Features:
-* secp256k1 ECDSA signing/verification and key generation.
-* Additive and multiplicative tweaking of secret/public keys.
-* Serialization/parsing of secret keys, public keys, signatures.
-* Constant time, constant memory access signing and public key generation.
-* Derandomized ECDSA (via RFC6979 or with a caller provided function.)
-* Very efficient implementation.
-* Suitable for embedded systems.
-* No runtime dependencies.
-* Optional module for public key recovery.
-* Optional module for ECDH key exchange.
-* Optional module for Schnorr signatures according to [BIP-340](https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki).
-* Optional module for ElligatorSwift key exchange according to [BIP-324](https://github.com/bitcoin/bips/blob/master/bip-0324.mediawiki).
-* Optional module for MuSig2 Schnorr multi-signatures according to [BIP-327](https://github.com/bitcoin/bips/blob/master/bip-0327.mediawiki).

-Implementation details
-----------------------
-
-* General
-  * No runtime heap allocation.
-  * Extensive testing infrastructure.
-  * Structured to facilitate review and analysis.
-  * Intended to be portable to any system with a C89 compiler and uint64_t support.
-  * No use of floating types.
-  * Expose only higher level interfaces to minimize the API surface and improve application security. ("Be difficult to use insecurely.")
-* Field operations
-  * Optimized implementation of arithmetic modulo the curve's field size (2^256 - 0x1000003D1).
-    * Using 5 52-bit limbs
-    * Using 10 26-bit limbs (including hand-optimized assembly for 32-bit ARM, by Wladimir J. van der Laan).
-      * This is an experimental feature that has not received enough scrutiny to satisfy the standard of quality of this library but is made available for testing and review by the community.
-* Scalar operations
-  * Optimized implementation without data-dependent branches of arithmetic modulo the curve's order.
-    * Using 4 64-bit limbs (relying on __int128 support in the compiler).
-    * Using 8 32-bit limbs.
-* Modular inverses (both field elements and scalars) based on [safegcd](https://gcd.cr.yp.to/index.html) with some modifications, and a variable-time variant (by Peter Dettman).
-* Group operations
-  * Point addition formula specifically simplified for the curve equation (y^2 = x^3 + 7).
-  * Use addition between points in Jacobian and affine coordinates where possible.
-  * Use a unified addition/doubling formula where necessary to avoid data-dependent branches.
-  * Point/x comparison without a field inversion by comparison in the Jacobian coordinate space.
-* Point multiplication for verification (a*P + b*G).
-  * Use wNAF notation for point multiplicands.
-  * Use a much larger window for multiples of G, using precomputed multiples.
-  * Use Shamir's trick to do the multiplication with the public key and the generator simultaneously.
-  * Use secp256k1's efficiently-computable endomorphism to split the P multiplicand into 2 half-sized ones.
-* Point multiplication for signing
-  * Use a precomputed table of multiples of powers of 16 multiplied with the generator, so general multiplication becomes a series of additions.
-  * Intended to be completely free of timing sidechannels for secret-key operations (on reasonable hardware/toolchains)
-    * Access the table with branch-free conditional moves so memory access is uniform.
-    * No data-dependent branches
-  * Optional runtime blinding which attempts to frustrate differential power analysis.
-  * The precomputed tables add and eventually subtract points for which no known scalar (secret key) is known, preventing even an attacker with control over the secret key used to control the data internally.

-Building with Autotools
------------------------
-
-    $ ./autogen.sh
-    $ ./configure
-    $ make
-    $ make check  # run the test suite
-    $ sudo make install  # optional
-
-To compile optional modules (such as Schnorr signatures), you need to run `./configure` with additional flags (such as `--enable-module-schnorrsig`). Run `./configure --help` to see the full list of available flags.
-
-Building with CMake (experimental)
-----------------------------------
-
-To maintain a pristine source tree, CMake encourages to perform an out-of-source build by using a separate dedicated build tree.
-
-### Building on POSIX systems
-
-    $ mkdir build && cd build
-    $ cmake ..
-    $ cmake --build .
-    $ ctest  # run the test suite
-    $ sudo cmake --install .  # optional
-
-To compile optional modules (such as Schnorr signatures), you need to run `cmake` with additional flags (such as `-DSECP256K1_ENABLE_MODULE_SCHNORRSIG=ON`). Run `cmake .. -LH` to see the full list of available flags.
-
-### Cross compiling
-
-To alleviate issues with cross compiling, preconfigured toolchain files are available in the `cmake` directory.
-For example, to cross compile for Windows:
-
-    $ cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/x86_64-w64-mingw32.toolchain.cmake
-
-To cross compile for Android with [NDK](https://developer.android.com/ndk/guides/cmake) (using NDK's toolchain file, and assuming the `ANDROID_NDK_ROOT` environment variable has been set):
-
-    $ cmake .. -DCMAKE_TOOLCHAIN_FILE="${ANDROID_NDK_ROOT}/build/cmake/android.toolchain.cmake" -DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=28
-
-### Building on Windows
-
-To build on Windows with Visual Studio, a proper [generator](https://cmake.org/cmake/help/latest/manual/cmake-generators.7.html#visual-studio-generators) must be specified for a new build tree.
-
-The following example assumes using of Visual Studio 2022 and CMake v3.21+.
-
-In "Developer Command Prompt for VS 2022":
-
-    >cmake -G "Visual Studio 17 2022" -A x64 -S . -B build
-    >cmake --build build --config RelWithDebInfo
-
-Usage examples
------------
-Usage examples can be found in the [examples](examples) directory. To compile them you need to configure with `--enable-examples`.
-  * [ECDSA example](examples/ecdsa.c)
-  * [Schnorr signatures example](examples/schnorr.c)
-  * [Deriving a shared secret (ECDH) example](examples/ecdh.c)
-  * [ElligatorSwift key exchange example](examples/ellswift.c)
-
-To compile the Schnorr signature and ECDH examples, you also need to configure with `--enable-module-schnorrsig` and `--enable-module-ecdh`.
-
-Benchmark
-------------
-If configured with `--enable-benchmark` (which is the default), binaries for benchmarking the libsecp256k1 functions will be present in the root directory after the build.
-
-To print the benchmark result to the command line:
-
-    $ ./bench_name
-
-To create a CSV file for the benchmark result :
-
-    $ ./bench_name | sed '2d;s/ \{1,\}//g' > bench_name.csv
