Change recovery address

Accounts can configure a recovery address to protect against the loss of the custody address. The recovery address will change the custody address of the account.

Requirements

• An ETH wallet that has an fid on OP mainnet, with some ETH for gas costs
• An ETH RPC URL for OP Mainnet (e.g. via Alchemy, Infura or QuickNode).

Change Address

Call the changeRecovery function on the Id Registry contract.

@farcaster/hub-web

import { walletClient, account, IdContract } from './clients.ts';

const newRecoveryAddress = '0x...';

const { request: transferRequest } = await walletClient.simulateContract({
  ...IdContract,
  functionName: 'changeRecovery',
  args: [newRecoveryAddress], // new recovery address
});

await walletClient.writeContract(transferRequest);

clients.ts

import {
  ID_REGISTRY_EIP_712_TYPES,
  idRegistryABI,
  ID_GATEWAY_ADDRESS,
} from '@farcaster/hub-web';
import { walletClient, account } from './clients.ts';

const IdContract = {
  abi: idRegistryABI,
  address: ID_GATEWAY_ADDRESS,
  chain: optimism,
};

import { createWalletClient, createPublicClient, custom, http } from 'viem';
import { privateKeyToAccount } from 'viem/accounts';
import { optimism } from 'viem/chains';

export const publicClient = createPublicClient({
  chain: optimism,
  transport: http(),
});

export const walletClient = createWalletClient({
  chain: optimism,
  transport: custom(window.ethereum),
});

// JSON-RPC Account
export const [account] = await walletClient.getAddresses();

// Local Account
export const account = privateKeyToAccount('0x...');
