Multisig

Short for multi-signature — any scheme that requires more than one cryptographic signature to authorize a transaction. Multisig can be implemented at the script level (Bitcoin P2SH/P2WSH), via threshold signature protocols (MuSig2, FROST), or through smart contracts (Safe Multisig on Ethereum). SSP's 2-of-2 multisig uses Bitcoin's native P2WSH script for its default Bitcoin wallet.
