  var privateKey = "私钥";
  var wallet = new ethers.Wallet(privateKey, customHttpProvider);
  const balance = await wallet.getBalance()
  console.log(balance)
  
  let tx = await wallet.sendTransaction({
        gasLimit: gasLimit,
        gasPrice: gasPrice,
        to: newAddress,
        value: value
    });

 const walletSigner = new ethers.Wallet(私钥, customHttpProvider);
  const gasPrice = await customHttpProvider.getGasPrice()
  let contract = new ethers.Contract(
    address,
    abi,
    walletSigner
  )
  
    const tx = await contract[方法](
	参数...
    {
      gasPrice,
      gasLimit: 300000,
      value: ethers.utils.parseEther(String(buyValue))
    })
	// 交易信息
	const transData = await tx.wait()
