Develop Automated Account Recovery Service

[gabito1451]

Context

Users losing access to their smart wallets.

Problem

No recovery mechanism for users who lose their Passkey/Device.

Suggested Execution

• Implement Social Recovery or Email-based 2FA recovery.
• Uses a background worker to submit the 'change_admin' transaction on-chain once verified.

Acceptance Criteria

• Users can regain account control via verified off-chain signals.
• Security-first implementation to prevent hijacking.
