Bundled Library for Linux AMD64

This directory contains a bundled copy of libsecp256k1 for Linux AMD64 systems.

Library Information

• File: libsecp256k1.so
• Version: 5.0.0
• Size: 1.8 MB
• Built: November 4, 2025
• Architecture: Linux AMD64
• Modules: Schnorr, ECDH, Recovery, Extrakeys

Why Bundled?

The bundled library provides several benefits:

1. Zero Installation - Works out of the box on Linux AMD64
2. Consistent Version - Ensures all users have the same tested version
3. Full Module Support - Built with all optional modules enabled
4. Performance - Optimized build with latest features

Usage

The library loader automatically tries the bundled library first on Linux AMD64:

ctx, err := secp.NewContext(secp.ContextSign | secp.ContextVerify)
// Uses bundled ./libsecp256k1.so on Linux AMD64

Build Information

The bundled library was built from the Bitcoin Core secp256k1 repository with:

./autogen.sh
./configure --enable-module-recovery \
            --enable-module-schnorrsig \
            --enable-module-ecdh \
            --enable-module-extrakeys \
            --enable-benchmark=no \
            --enable-tests=no
make

Fallback

If the bundled library doesn't work for your system, the loader will automatically fall back to system-installed versions:

1. libsecp256k1.so.5 (system)
2. libsecp256k1.so.2 (system)
3. /usr/lib/libsecp256k1.so
4. /usr/local/lib/libsecp256k1.so
5. /usr/lib/x86_64-linux-gnu/libsecp256k1.so
