How zk Email helps with account recovery

This is an ongoing effort to educate people on some real world application of zero-Knowledge tech. Read through and share your feedback.

Picture this: You've got your ETH safely tucked away in your Ethereum wallet. Life is good. Then one day, disaster strikes, you lose your seed phrase. Maybe your backup got destroyed, or you stored it "somewhere safe" that's now a mystery. Whatever happened, that sick feeling in your stomach is real because in the world of Ethereum, there's no "Forgot Password?" button.

Why? It's actually by design. Ethereum wallets are built on hardcore cryptography where your seed phrase creates your private keys, which control your funds. The blockchain only knows about public addresses and balances - it has zero information about private keys or recovery info .This is what makes crypto self-sovereign (you're the only one in control), but it's also what makes it terrifying when things go wrong.

But here's where things get interesting. Enter ZK Email (https://prove.email/) : A solution that brings email-based recovery to crypto wallets without sacrificing what makes crypto special. And the best part? It comes in two flavors depending on your needs:

  1. For existing Safe Wallet users: You can add recovery capabilities by installing and enabling a special recovery module.

  2. For new users: You can start with a Burner Safe that comes with recovery already built-in using the latest account abstraction standards (ERC-4337 and ERC-7579).

Here's how it works in practiceπŸ‘‡πŸ‘‡

Setting Up Recovery:

  • If you're using a Safe Wallet, you'll first enable the Email Recovery Module: think of it as installing a safety net for your wallet.

  • You'll set up a trusted email address as your "guardian" with specific recovery parameters.

  • Your guardian needs to confirm their role through an email verification process.

  • For Burner Safe users, this comes pre-configured : just enter your guardian email and you're set.

The Recovery Process:

  1. When you need to recover your wallet, you start by specifying two crucial pieces of information:

    • Your guardian's email address

    • The new wallet address that should take control (this must be different from your old one)

  2. Your guardian receives a specific recovery request email

  3. When they reply "Confirm", the system springs into action with some serious cryptographic magic:

    • ZK Email generates a zero-knowledge proof verifying the email's authenticity

    • This proof confirms the email came from your guardian without revealing the actual email contents

    • The system verifies this was in response to a legitimate recovery request

  4. The recovery module checks all this cryptographic evidence on-chain

  5. If everything checks out, your wallet ownership transfers to the new address you specified

What makes this better than traditional multisig or social recovery? It leverages email, something everyone understands, but wraps it in multiple layers of cryptographic certainty. Your guardian can't just randomly give away access to your wallet; they must receive and respond to a specific recovery email. The zero-knowledge proofs ensure everything happens exactly as intended, with no room for manipulation.

We're finally seeing solutions that make crypto more human-friendly without sacrificing what makes it revolutionary in the first place. No more permanent lockouts, no more lost crypto horror stories.

Just the security we need with the recovery options we deserve.
