@zerodev/recovery

This package offers UI components for DApp developers to easily integrate account recovery. The useKernelAccountRecovery hook opens a pop-up that guides the user through setting up a guardian.

You can see a demo here:

The guardian can complete recovery at the recovery portal.

Installation

To install the package, run the following command:

npm install @zerodev/recovery

or

yarn add @zerodev/recovery

Usage

Here is how to use the useKernelAccountRecovery hook in your React application:

import React from 'react';
import { useKernelAccountRecovery } from "@zerodev/recovery";

function App() {
  const kernelAddress = '0x...'; // Replace with the actual kernel address
  const suggestedGuardianAddress = '0x...'; // Replace with the actual suggested guardian address
  const chainId = 1; // Replace with the actual chain ID

  const { openRecoveryPopup, error, recoveryEnabled, guardians, isPending } = useKernelAccountRecovery({
    address: kernelAddress,
    chainId,
    suggestedGuardianAddress, // optional
    onSetupGuardianRequest: async (userOpCallData) => {
      // Implement the logic to handle the user operation call data
    }
  });

  return (
    <div>
      <button onClick={openRecoveryPopup}>Manage Recovery Guardians</button>
      {error && <p>Error: {error}</p>}
      {isPending && <p>Guardian update in progress...</p>}
      {recoveryEnabled && (
        <div>
          <h3>Guardians</h3>
          {guardians.map((guardian, index) => (
            <p key={index}>{guardian}</p>
          ))}
        </div>
      )}
    </div>
  );
}

export default App;

The popup assembles this call data based on user preferences and then forwards it to this callback function for your implementation to manage. | Yes | | defaultGuardianAddress| string | (Optional) A pre-specified guardian address to prefill in the popup, ideal for suggesting your wallet as a guardian. While this address is set as the prefilled option, users retain the option to modify it within the popup as needed. | No |
