A safe plugin that allows Safe owners to recover the ownership of the account in the case where they lose access to their Safe. All the recovery methods leverage Noir, a DSL for writing zero-knowledge proof circuits to help owners recover their account ownership in a secure and private manner.
Recovery Mechanism
Available recovery methods with zero-knowledge proofs of...
- TouchID: correct verification of the p256 ECDSA signature with a fingerprint (via WebAuthn).
- Shielded Backup Address: correct verification of the k256 ECDSA signature. Public keys are hidden(hashed).
- Social Recovery: correct verification of the k256 ECDSA signatures from private guardians.
- Secret Word: knowledge of a particular secret word to regain account ownership.
- (methods To be added: 2FA, email, and other biometrics)
This recovery app is built on top of safe-core-protocol, a modular smart account protocol so that Safe and other wallet apps can easily integrate to enhance the security of user funds. The recovery plugin performs a batched call that executes swapOwner and changeThreshold simultaneously to flexibly transfer the account authorities and change the multi-signature set-up.
