123varurl=" http://localhost:8545 " ;varprivateKey=" 0xb5b1870957d373ef0eeffecc6e4812c0fd08f554b37b233526acc331bf1544f7 " ; varethTransfer=newEthTransferUnityRequest ( url , privateKey , " YOURCHAINID " );一旦我们的请求被实例化，就可以使用传统模式启动传输，下面的代码设置 2 Gwei 作为gas价格:
12var receivingAddress = "0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe";yield return ethTransfer.TransferEther(receivingAddress, 1.1m, 2);在这里，我们指定了接收地址、发送量和可选的 gas 价格 。该请求将自动将 gas 价格转换为 Wei 。
我们可以在之后验证是否有任何异常，如下所示：
12345if (ethTransfer.Exception != null){Debug.Log(ethTransfer.Exception.Message);yield break;}如果没有发生错误，我们可以每 2 秒从请求和轮询中检索交易哈希以等待交易确认：
12345var transactionHash = ethTransfer.Result;//create a poll to get the receipt when minedvar transactionReceiptPolling = new TransactionReceiptPollingRequest(url);//checking every 2 seconds for the receiptyield return transactionReceiptPolling.PollForReceipt(transactionHash, 2);最后，我们可以使用EthGetBalanceUnityRequest检查收款账户的余额 。请注意，我们在执行 请求时声明想要最新块记录的余额 。
12var balanceRequest = new EthGetBalanceUnityRequest(url);yield return balanceRequest.SendRequest(receivingAddress, BlockParameter.CreateLatest());可以使用默认的 Wei UnitConvertor 将 Wei 中的结果转换为 Eth：
1Debug.Log("Balance of account:" + UnitConversion.Convert.FromWei(balanceRequest.Result.Value));6、EIP 1559 使用建议以下是使用协程、TimePreference、MedianFeeHistory 或 LegacyMode 提供的费用建议策略以使用 旧模式或与其他链一起使用的一些示例 。
要使用 LegacyMode，你必须提供 GasPrice，或者可以通过设置UseLegacyAsDefault为 true 来强制 LegacyMode：
