Multisig (Multi-Signature)
A wallet that requires multiple private keys to authorize a transaction, adding an extra layer of security.
A multisig wallet might require 2 of 3 keys, 3 of 5, or any combination to sign a transaction. This means no single person can move funds alone. If one key is compromised, the attacker still can't access the funds without the other required keys.
Multisig is used by organizations to manage treasury funds, DAOs to govern community funds, and security-conscious individuals who want protection against a single point of failure.
For USDC holders managing significant amounts (business treasury, team funds), a multisig wallet like Gnosis Safe adds a critical security layer. You can require multiple team members to approve transfers, preventing unauthorized spending.
