Nunchuk

Nunchuk is a privacy-first, open-source, non-custodial multisignature Bitcoin wallet that has helped secure over $1 billion in Bitcoin. It offers flexible multisig configurations (2-of-3, 3-of-5, 4-of-7, etc.) with open standards recovery. Unlike platforms that bundle service and keys, Nunchuk is a coordination layer where you choose who holds keys, how many, and unlock conditions. Features include zero KYC requirements, connect to your own node, Tor support via Orbot on mobile, and time-locked inheritance claims without KYC. The 2025 Taproot Multisig Wallet uses Schnorr signatures and MuSig2 for enhanced privacy and lower fees, making multisig transactions appear identical to single-sig. Works with Jade, Coldcard, and TAPSIGNER hardware wallets. End-to-end encrypted chat for coordination.
