Safe wallets have signers who are authorized individuals or entities responsible for approving transactions and are typically designated as wallet owners. The number of required signatures and the specific identities of signers are determined during the wallet setup and can be changed. Transactions are only executed when the predetermined threshold of signers provides their approval, preventing a single point of failure and ensuring collaborative control over digital assets.
