Wallet Integration & AA Wallet | zkLink X Documentation

·

💡 Account abstraction unifies contract accounts and EOAs. Integrating AA wallets enhances user experience for dApps built on zkLink. Smart contract wallets offer superior flexibility compared to EOAs, enabling users to:

  • Control accounts via smart contracts (not just private keys)
  • Customize account logic (permissions, transaction limits, recovery, etc.)

Why AA Wallets Matter for zkLink

AA (Account Abstraction) wallets like UniPass revolutionize crypto accessibility by:

Example: UniPass users generate a zkLink_key client-side during browser-based signing—never exposed to servers (MPC architecture).


Integration Requirements

Core Conditions

EIP-712 Signing Support
zkLink_key Generation

Recommended Enhancements

🔹 Proxy Deposit Contract Compatibility


Security Standards: The Dunkirk Test

AA wallets must ensure:

  1. Non-custodial asset control (no agency dependence)
  2. Service-agnostic recovery (e.g., if provider shuts down)
