.NET Core 波场链离线签名、广播交易（发送 TRX和USDT）笔记

Get Started

NuGet

You can run the following command to install the Tron.Wallet.Net in your project.

PM> Install-Package Tron.Wallet.Net

配置

public record TronRecord(IServiceProvider ServiceProvider, ITronClient? TronClient, IOptions<TronNetOptions>? Options);

public static class TronServiceExtension {

    private static IServiceProvider AddTronNet() {

        IServiceCollection services = new ServiceCollection();

        services.AddTronNet(x =>

        {

            x.Network = TronNetwork.MainNet;

            x.Channel = new GrpcChannelOption { Host = "grpc.trongrid.io", Port = 50051 };

            x.SolidityChannel = new GrpcChannelOption { Host = "grpc.trongrid.io", Port = 50052 };

            x.ApiKey = "api key"; //https://trongrid.io 邮箱注册申请，免费50万次调用

        });

        services.AddLogging();

        return services.BuildServiceProvider();

    }

    public static TronRecord GetRecord() {

        var provider = AddTronNet();

        var client = provider.GetService<ITronClient>();

        var options = provider.GetService<IOptions<TronNetOptions>>();

        return new TronRecord(provider, client, options);

    }

}

转出/发送 TRX

private static async Task<dynamic> TrxTransferAsync(string privateKey, string to, long amount) {

    var record = TronServiceExtension.GetRecord();

    var transactionClient = record.TronClient?.GetTransaction();

    var account = new TronAccount(privateKey, TronNetwork.MainNet);

    var transactionExtension = await transactionClient?.CreateTransactionAsync(account.Address, to, amount)!;

    var transactionId = transactionExtension.Txid.ToStringUtf8();

    var transactionSigned = transactionClient.GetTransactionSign(transactionExtension.Transaction, privateKey);

    var returnObj = await transactionClient.BroadcastTransactionAsync(transactionSigned);

    return new { Result = returnObj.Result, Message = returnObj.Message, TransactionId = transactionId };

}

转出/发送 USDT

private static async Task<string> EtherTransferAsync(string privateKey, string toAddress, decimal amount, string? memo) {

    const string contractAddress = "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t";

    var record = TronServiceExtension.GetRecord();

    var contractClientFactory = record.ServiceProvider.GetService<IContractClientFactory>();

    var contractClient = contractClientFactory?.CreateClient(ContractProtocol.TRC20);

    var account = new TronAccount(privateKey, TronNetwork.MainNet);

    const long feeAmount = 30 * 1000000L;

    return await contractClient.TransferAsync(contractAddress, account, toAddress, amount, memo, feeAmount);

}

这里要设置波场手续费上限，现在必须设置30TRX，否则有可能交易失败，太贵了。其它 trc20 合约也是一样的操作，替换掉合约地址即可。

注意trc20合约交易的 amount 是 decimal 类型，不需要转换成 long 型

static async Task Main(string[] args) {

    Console.WriteLine("Program begin..");

    var privateKey = "D95611A9AF2A2A45359106222ED1AFED48853D9A44DEFF8DC7913F5CBA727366";

    //发送 trx

    var result = await TrxTransferAsync(privateKey, "TGehVcNhud84JDCGrNHKVz9jEAVKUpbuiv", 10000000L);

    Console.WriteLine(JsonConvert.SerializeObject(result));

    //发送 trc20 token usdt

    var transactionId = await EtherTransferAsync(privateKey, "TGehVcNhud84JDCGrNHKVz9jEAVKUpbuiv", 10, string.Empty);

    Console.WriteLine(transactionId);

    Console.WriteLine("Program end..\r\nPress any key to exit.");

    Console.ReadKey();

}

这个类库非常的简单，几乎不用去关心波场链的东西，只需要生成私钥和地址，就可以轻松完成对地址里面的 trx 和 usdt 等资产进行管理操作。
