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:

Zero Installation - Works out of the box on Linux AMD64
Consistent Version - Ensures all users have the same tested version
Full Module Support - Built with all optional modules enabled
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:

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

Other Platforms

For other platforms (macOS, Windows, or other architectures), install libsecp256k1 using your system package manager:

macOS:

brew install libsecp256k1
