Blocky saysMultisig wallets require several keys to approve a transaction — m-of-n security.
A multisignature wallet (e.g. Gnosis Safe) needs m of n keys to sign before funds move — say 2-of-3. This removes the single point of failure: losing one key (or one signer being compromised) doesn't lose the funds or let an attacker act alone. It's standard for treasuries, DAOs, and shared/business custody where no one person should have unilateral control.
