A production-ready Multi-Party Computation (MPC) wallet implementing FROST (Flexible Round-Optimized Schnorr Threshold) signatures for secure distributed key management across multiple platforms.
MPC Wallet enables threshold signatures where private keys are split across multiple parties, requiring a minimum threshold to sign transactions. No single party ever has access to the complete private key, providing superior security for digital asset management.
- Real FROST DKG: Cryptographically secure distributed key generation using proper FROST protocol
- Threshold Signatures: Configurable t-of-n threshold signing
- Multi-Platform: Browser extension, desktop GUI, and terminal UI
- Multi-Chain Support: Ethereum (secp256k1) and Solana (ed25519)
- Peer-to-Peer: Direct WebRTC connections between participants
- Offline Mode: Air-gapped operations for maximum security
- Production Ready: Comprehensive testing and security audits
