Sample

Sample 1: Generate Address Offline

namespace ConsoleApp1;

using Tron;

internal class Program {    
    private static void Main() {
        var tronEcKey = TronECKey.GenerateKey(TronNetwork.MainNet);
        var privateKey = tronEcKey.GetPrivateKey();
        var address = tronEcKey.GetPublicAddress();

        Console.WriteLine($"{privateKey}\t{address}");
    }
}

Sample 2: Transfer TRX/USDT and account permission update

namespace ConsoleApp1;

using Microsoft.Extensions.DependencyInjection;

using Tron;

        var ownerAddress = "your owner address here.";
        var r = await AccountPermissionUpdateAsync(privateKey, ownerAddress);

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

    private static async Task<dynamic> AccountPermissionUpdateAsync(string privateKey, string ownerAddress) {
