如何在 Monad 上使用 ERC-6551(代币绑定账户)构建

npm install @tokenbound/sdk viem@^2.40.0

import { TokenboundClient } from "@tokenbound/sdk"
import { createWalletClient, custom } from "viem"
import { monad } from "viem/chains" // chain 10143 使用 monadTestnet

const [account] = (await window.ethereum.request({
  method: "eth_requestAccounts",
})) as [`0x${string}`]

const walletClient = createWalletClient({
  account,
  chain: monad,
  transport: custom(window.ethereum),
})

const tokenboundClient = new TokenboundClient({
  walletClient,
  chain: monad,
})

// NFT 合约 tokenId 1 的确定性账户地址
const account = tokenboundClient.getAccount({
  tokenContract: "0xYourNftContract",
  tokenId: "1",
})

// 在链上部署账户(幂等 —— 若已存在则可安全再次调用)
const { account: created, txHash } = await tokenboundClient.createAccount({
  tokenContract: "0xYourNftContract",
  tokenId: "1",
})

const executedTxHash = await tokenboundClient.execute({
  account,
  to: "0xRecipient",
  value: 0n,
  data: "0x",
})
