Multisig Wallets: A 2-of-3 Bitcoin Setup in Just 15 Minutes

A hardware wallet protects you from remote hackers, but it's not foolproof. If you lose your seed phrase or get physically coerced, a single device can still be compromised.

Multisignature (multisig) wallets fix this issue by splitting spending authority across two or more devices, ensuring no single lost key or stolen device can drain the wallet.

Sparrow Wallet is a free and open-source desktop coordinator that enables 2-of-3 multisig setup. It connects to your own Bitcoin Core full node and manages the signing workflow without holding private keys.
