发送原生代币

async sendNativeToken() {
  try {
    const tx = {
      from: fromAddress,
      to: toAddress,
      value: parseEther(toAmount).toHexString(),
      data: "0x",
    };
    txHash.value = await upWallet.sendTransaction(tx);
    if (await checkTxStatus(txHash)) {
      console.log("send Native Token success", txHash);
    } else {
      console.error(`send Native Token failed, tx hash = ${txHash}`);
    }
  } catch (err) {
    console.log("err", err);
  }
}

发送 ERC20 代币

async sendToken() {   
  try {
        const tokenAddress = '0x25c58Aa062Efb4f069bD013De3e3C5797fb40651';
        const data = new utils.Interface(['function transfer(address _to, uint256 _value)']).encodeFunctionData('transfer', [toAddress, amount]);
    const tx = {
      from: fromAddress,
      to: tokenAddress,
      value: "0x0";,
      data: data,
    };
    txHash.value = await upWallet.sendTransaction(tx);
    if (await checkTxStatus(txHash)) {
      console.log("send Token success", txHash);
    } else {
      console.error(`send Token failed, tx hash = ${txHash}`);
    }
  } catch (err) {
    console.log("err", err);
  }
}

调用合约

与合约交互的方式跟 发送 ERC20 代币 的方式类似，构建出调用 data 后，直接使用 sendTransaction 完成交易的发送。
