W6fux5.ChainKit.Core 0.1.0

ChainKit

Multi-chain blockchain SDK for .NET. Currently supports Tron.

Installation

dotnet add package W6fux5.ChainKit.Tron

W6fux5.ChainKit.Core is included as a dependency automatically.

Quick Start

using ChainKit.Tron;
using ChainKit.Tron.Crypto;
using ChainKit.Tron.Providers;

// Connect to Tron network
using var provider = new TronHttpProvider(TronNetwork.Nile);  // Testnet
using var client = new TronClient(provider);

// Create or import account
var account = TronAccount.FromPrivateKey(Convert.FromHexString("your_private_key_hex"));

// Transfer TRX
var result = await client.TransferTrxAsync(account, "TReceiverAddress...", 10m);
if (result.Success)
    Console.WriteLine($"TxId: {result.Data!.TxId}");

// Query balance
var balance = await client.GetBalanceAsync(account.Address);
Console.WriteLine($"TRX: {balance.Data!.TrxBalance}");

Features

High-Level API (TronClient)

• Transfer: TRX transfers with automatic ref block handling
• Balance: TRX + TRC20 token balances in one call
• Staking: Stake/unstake TRX for Energy/Bandwidth (Stake 2.0)
• Delegation: Delegate/undelegate resources to other addresses
• Resource Rate: Bidirectional TRX ↔ Energy/Bandwidth exchange rate estimation
• Transaction Detail: Merged Full Node + Solidity Node transaction info with status tracking

TRC20 Contracts (Trc20Contract)

• Token Info: Name, symbol, decimals, total supply, deployer address (parallel queries)
• Transfer / Approve / Allowance: Standard ERC20-compatible operations
• Mint / Burn: Extended operations for mintable/burnable tokens
• Deploy: Deploy custom TRC20 tokens from built-in template

Transaction Watching (TronTransactionWatcher)

• Real-time monitoring: Watch addresses for incoming/outgoing TRX and TRC20 transfers
• Confirmation tracking: Automatic Solidity Node confirmation with failure detection
• Two stream sources: PollingBlockStream (HTTP) or ZmqBlockStream (self-hosted node)

Providers

• TronHttpProvider: HTTP/HTTPS with dual endpoint support (Full Node + Solidity Node)
• TronGrpcProvider: gRPC for high-performance scenarios
• Optional ILogger: All classes accept optional ILogger<T> for diagnostics

Dual Endpoint Setup

For accurate transaction confirmation, configure separate Full Node and Solidity Node endpoints:

var provider = new TronHttpProvider(
    baseUrl: "http://your-fullnode:8090",
    solidityUrl: "http://your-soliditynode:8091");

TRC20 Example

using var contract = client.GetTrc20Contract("TContractAddress...", account);

// Get token info
var info = await contract.GetTokenInfoAsync();
Console.WriteLine($"{info.Data!.Symbol} - Decimals: {info.Data.Decimals}");

// Transfer tokens
var tx = await contract.TransferAsync("TReceiverAddress...", 100m);

Resource Exchange Rate

var rate = await client.GetResourceExchangeRateAsync(ResourceType.Energy);
Console.WriteLine($"1 TRX = {rate.Data!.ResourcePerTrx:F2} Energy");
Console.WriteLine($"100 TRX = {rate.Data.EstimateResource(100m):F0} Energy");
Console.WriteLine($"10000 Energy = {rate.Data.EstimateTrx(10000):F2} TRX");

Requirements

• .NET 10.0+
