frost-taproot

Rust implementation of BIP-340 FROST (Flexible Round-Optimized Schnorr Threshold) signatures for Bitcoin Taproot.

Features

• FROST signing - Threshold signatures compatible with BIP-340 Schnorr
• Trusted dealer - Centralized key generation and share distribution
• DKG (Distributed Key Generation) - Decentralized key generation without a trusted dealer
• Share refresh - Refresh shares without changing the group public key
• Share recovery - Recover shares using VSS (Verifiable Secret Sharing)
• Compatible - Compatible with the @cmdruid/frost TypeScript implementation

Usage

Add to your Cargo.toml:

[dependencies]
frost-taproot = { path = "../frost-taproot-rust" }
