Understanding Frostsnap's security model, design philosophy, and the FROST protocol.
Having your keys in a single location makes you an inviting target to criminals. Sophisticated physical and digital thefts against bitcoin owners are becoming more prevalent. Frostsnap protects you by providing accessible threshold multisignature: with a 2-of-3 setup, any two devices must sign to access your bitcoin.
Bitcoin's Taproot upgrade has enabled elegant and secure Schnorr threshold signatures — a single public key that pays the same fees as single signature wallets, has hidden multisig for privacy, and straightforward recovery requirements.
