How the GreenAddress Wallet Works
GreenAddress is a multisig wallet focused on enhancing Bitcoin security, typically using a 2-of-2 configuration, which requires both the user and the wallet service provider to sign transactions. It integrates transaction-level two-factor authentication (2FA) and ensures users maintain full control over their private keys. Even if the service is interrupted, users can recover funds through pre-set timelock transactions. GreenAddress was acquired by Blockstream in 2016 but continues to operate independently, and was an early adopter of innovative technologies in the Bitcoin wallet space, such as multisig and HD wallets.
