Multisig Wallet
Web3 Infrastructure • Tools • Interfaces
Multisig Wallet (short for multi-signature wallet) is a type of cryptocurrency wallet that requires multiple private keys to authorize a transaction, rather than a single signature. This adds an extra layer of security and is commonly used by organizations, DAOs, and individuals who want shared control over funds. For example, a 2-of-3 multisig setup requires any two of three key holders to approve a transaction.
Use Case: A DAO treasury stores its reserves in a 3-of-5 multisig wallet to ensure no single member can unilaterally move its gold-backed tokens.
