Problem Statement

Z0Wallet Is a privacy focused multi sig wallet powered by the risc0 stack. the signers of the wallet are never revealed and the multi sig round is verified offchain and converted into proofs to be verified later. this results in a cheaper smart contract wallet as compared to existing solutions which handle this logic onchain

Solution

The wallet provides an off-chain guest code that computes the state root of the wallet, which encapsulates the current signers and threshold and then takes in the intended call to be made via the z0 wallet and verifies the signatures until the threshold is met. once signatures are validated and enough. a proof is generated with a journal which is validated on the wallet on chain
