更改托管地址

账户由托管地址拥有，该地址是 OP 主网上的一个以太坊地址。

用户可能出于安全考虑或需要转移整个账户所有权而更改此地址。

要求

• 一个在 OP 主网上拥有该账户的 ETH 钱包，且钱包中有少量 ETH。
• 一个 OP 主网的以太坊提供商 URL（例如通过 Alchemy、Infura 或 QuickNode）。

更改托管地址

调用 Id Registry 合约的 transfer 函数。接收地址必须提供一个 EIP-712 签名以接受转移。

import { ViemWalletEip712Signer } from '@farcaster/hub-web';
import { walletClient, account } from './clients.ts';

const nonce = await readNonce();
const deadline = getDeadline();

const eip712Signer = new ViemWalletEip712Signer(walletClient);
const signature = await eip712signer.signTransfer({
  fid: 1n,
  to: account,
  nonce,
  deadline,

const { request: transferRequest } = await publicClient.simulateContract({
  ...IdContract,
  functionName: 'transfer',
  args: [account, deadline, signature], // to, deadline, signature

WARNING

转移 FID 不会重置其恢复地址。如需转移 FID 并更新其恢复地址， 请调用 transferAndChangeRecovery。
