Implementing Social Recovery for Mobile Crypto Wallet

Social Recovery allows regaining wallet access without seed phrase — via trusted people (guardians). User lost phone, doesn't remember seed — guardians confirm owner change. Mechanics work at smart contract level, mobile is UX layer.

How It Works at Contract Level

Candidate standard — EIP-2525 (not finalized) with implementations in Safe, ZeroDev, Argent. Basic logic:

  1. Wallet — smart account (ERC-4337 or custom).
  2. On setup owner sets guardian list (addresses) and threshold (N of M).
  3. On access loss: guardians confirm initiateRecovery(newOwner).
  4. After collecting N signatures and optional timelock (24–72 hours) — finalizeRecovery changes owner.

Mobile implements: guardian setup screen, recovery initiation flow (on new device), confirmation screen (for guardians).

Who Are Guardians Technically

Options: other wallets (addresses) of trusted people, email via ZK-Email Guardian (verify email without content exposure), hardware wallet, another smart account.

For mobile app most practical — guardian addresses of other app users. Flow:

  1. User A adds guardian → enters address or scans User B QR.
  2. User B gets push and accepts/rejects guardian role.
  3. Accepting guardian role — addGuardian in User A's wallet contract.

Recovery Flow on New Device

User installs app on new device. Generates new keypair. Initiates recovery with new address — sends request to guardians via push/email.

Each guardian sees: whose wallet recovers, new address, request timestamp. Confirms via own wallet — approveRecovery UserOperation.

Timelock critically important: if owner compromised (not lost), timelock gives time to cancel fraudulent recovery via cancelRecovery with original key.

What's Hard to Implement

Off-chain state. Guardian not always online when recovery needed. Need centralized notification queue or push mechanism. Without this recovery hangs.

Guardian removal. If user falls out with guardian — need removal flow. removeGuardian via owner key. What if owner key lost? Then only through other guardians with raised threshold.

Status display. User sees: "2 of 3 guardians confirmed, waiting for 1, timelock expires in 18 hours". This polling contract or event subscription via WebSocket (eth_subscribe).

Process

Audit existing contract architecture (or choose from ready: Safe, ZeroDev). Implement guardian setup UI, recovery initiation and confirmation flow, push notifications for guardians, recovery status monitoring.

Timeline — 3–5 days for existing smart account with Social Recovery already in contract. If contract needs writing — separate scope. Custom pricing after requirements analysis.
