Multisig wallets are often used for DAO treasury management. Although some of the more popular names in the space include Coinbase and Armory, there are many different multisig wallter solutions available today. They’re digital wallets that require the use of at least two private keys for transaction approval, where each private key is held by a different DAO member. The treasury funds are highly secured and locked into a smart contract, where every transaction must receive multiple levels of approval.
