A multisig wallet, or multisignature wallet, is a type of cryptocurrency wallet that requires more than one signature or approval in order to complete a transaction. This is in contrast to a traditional wallet, which only requires a single signature or approval.

Multisig wallets are designed to provide an additional layer of security by requiring multiple approvals before a transaction can be completed. They can be used to prevent unauthorized transactions and to ensure that multiple parties are involved in the decision-making process for financial transactions.
