Multisig Wallet Comparison: Security, Setup, and Software Picks
Multisig wallets require multiple keys to authorize transactions, which removes single points of failure since a hacker would need to compromise multiple attack points rather than one. The tradeoff is added complexity in setup and recovery, plus higher transaction fees since multisig transactions are larger in size. You need to back up all individual seed phrases, your cosigners' xpubs, and your wallet descriptor file. Users recommend Sparrow, Nunchuk, Electrum, and Specter for managing multisig setups.
Setting Up a Multisig Wallet Step by Step
To set up a multisig wallet, choose a compatible application and determine how many keys are required to authorize transactions, like a 2 of 3 configuration. You generate individual keys across separate devices, such as hardware wallets or phones, keeping in mind that each key has a seed phrase and an extended public key. Securing your backups is essential. You must store all seed phrases offline and include the master public keys with each backup so the wallet can be rebuilt if something goes wrong.
