Nodejs 端使用示例

V5 版本写法

钱包创建

function createWallet() {
  const { address, privateKey, mnemonic } = Wallet.createRandom();
  console.log({ address, privateKey, mnemonic });
}

直接转账 ETH

async function transfer() {
  const privateKey = "";
  const provider = new ethers.providers.JsonRpcProvider("");
  const wallet = new Wallet(privateKey, provider);
  const tx = await wallet.sendTransaction({
    to: "", // receiver
    value: utils.parseEther("0.1"), // 转 0.1 ETH
    data: "", // 如果只是转ETH，不需要填写。对于以太铭文是填写在这里
  });
  await tx.wait(3); // 等待3个确认块
  console.log({ txhash: tx.hash });
}

调用合约

async function callContract() {
  const privateKey = "";
  const contractAddress = "";
  const abi = [{ stateMutability: "payable", type: "testFunc" }];
  const provider = new ethers.providers.JsonRpcProvider("");
  const wallet = new Wallet(privateKey, provider);
  const contract = new Contract(contractAddress, abi, wallet);
  const tx = await contract.testFunc({
    value: utils.parseEther("0.1"), // 如果这个合约方法是一个payable的，需要支付0.1ETH才需要这个字段
  });
  await tx.wait();
  console.log({ txhash: tx.hash });
}

另一种写法

async function callContract2() {
  const privateKey = "";
  const contractAddress = "";
  const abi = [{ stateMutability: "payable", type: "testFunc" }];
  const provider = new ethers.providers.JsonRpcProvider("");
  const signer = new Wallet(privateKey, provider);
  const contract = new Contract(contractAddress, abi);
  contract.connect(signer);
  const tx = await contract.testFunc({
    value: utils.parseEther("0.1"), // 如果这个合约方法是一个payable的，需要支付0.1ETH才需要这个字段
  });
  await tx.wait();
  console.log({ txhash: tx.hash });
}
