A wallet or contract that requires multiple private keys to authorize transactions for added security.
Multisig (multi-signature) is a security feature where multiple private keys are required to authorize a blockchain transaction. Multisig wallets reduce single-point-of-failure risks and are commonly used by teams, institutions, and treasuries.
How Multisig Works
A multisig wallet can require:
2-of-3 keys
3-of-5 keys
Or any custom combination
Only when the required number of signatures is provided will a transaction be approved.
Benefits of Multisig
Strong protection against key theft
Prevents unauthorized fund movement
Ideal for company treasuries, DAOs, and shared accounts
Enhances operational security
Multisig significantly reduces insider risk and external attacks.
Multisig in Practice
Often used for:
DAO treasury management
Custodial security
Cold wallet storage
Shared control of protocol upgrades
Institutional asset management
Platforms like Gnosis Safe and Fireblocks popularize multisig workflows.
Summary
A multisig wallet requires multiple approvals to sign a transaction, offering stronger security and shared control for high-value or team-managed funds.
