Dzeta.TonSdk.Core 0.5.0

Dzeta.TonSdk.NET

Note: This is a fork of TonSdk.NET with critical bug fixes and improvements.

Key changes:

• Thread-safety fixes: Replaced Dictionary with ConcurrentDictionary in LiteClient for concurrent request handling
• Bounds checking: Added BOC deserialization safety checks to prevent "Index out of range" errors
• Address struct: Rewritten Address as a high-performance struct using fixed byte and ReadOnlySpan<byte>
• EF Core integration: New extension package for Entity Framework Core value converters
• Atomic operations: Proper use of TryAdd/TryRemove for thread-safe request management

Status: Currently only Core, Adnl, and EntityFrameworkCore packages are published. Other packages (Client, Contracts, Connect, DeFi) will be added incrementally with improvements.

Packages

Dzeta.TonSdk.Core

Core library with types and structures for TON Blockchain. Includes:

• Address as high-performance struct with fixed byte hash storage
• Coins for TON, Jetton amounts
• BOC serialization/deserialization with bounds checking
• Cell, Builder, Slice
• Mnemonic (BIP39 and TON standards)
• Ed25519 signing

dotnet add package Dzeta.TonSdk.Core

Dzeta.TonSdk.Adnl

Thread-safe ADNL client and LiteClient for interacting with TON blockchain nodes. Includes:

• ADNL protocol implementation
• LiteClient with concurrent request handling (ConcurrentDictionary)
• Atomic operations for safe multi-threaded access
• Block and account state queries

dotnet add package Dzeta.TonSdk.Adnl

Dzeta.TonSdk.Core.EntityFrameworkCore

Entity Framework Core integration for TonSdk.Core types. Includes:

• AddressValueConverter - stores Address as 36 bytes (4 bytes workchain + 32 bytes hash)
• AddressStringValueConverter - stores Address as human-readable string (~80 bytes)
• Extension methods for easy configuration

dotnet add package Dzeta.TonSdk.Core.EntityFrameworkCore

Usage example:

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    modelBuilder.Entity<Wallet>()
        .Property(e => e.Address)
        .HasAddressConversion<Wallet>(); // Binary storage (36 bytes)
}

Features and Status

• Builder, Cell, Slice
• BOC (de)serialization with bounds checking
• Hashmap(E) (dictionary) (de)serialization
• Mnemonic BIP39 standard
• Mnemonic TON standard
• Coins (class for TON, JETTON, etc.)
• Address (struct with fixed byte for high performance)
• Message layouts (MessageX, etc.)
• Popular structures from block.tlb
• Ed25519 signing of transactions
• ADNL client (thread-safe)
• Lite client over ADNL client (thread-safe)
• EF Core value converters for TON types
• Client with HTTP API (coming soon)
• Contracts abstraction (coming soon)
• TON Connect 2.0 (coming soon)
• DeFi integrations (coming soon)

Installation

Install via NuGet Package Manager or .NET CLI:

dotnet add package Dzeta.TonSdk.Core
dotnet add package Dzeta.TonSdk.Adnl
dotnet add package Dzeta.TonSdk.Core.EntityFrameworkCore  # Optional, for EF Core users

Quick Start

Using Address

using TonSdk.Core;

// Parse address
var address = new Address("EQDk2VTvn04SUKJrW7rXahzdF8_Qi6utb0wj43InCu9vdjrR");

// Get raw format
string raw = address.ToRaw(); // "0:e4d954ef9f4e1250a26b5bbad76a1cdd17cfc08babaddf4c23e37227..."

// Get workchain and hash
int workchain = address.Workchain; // 0
ReadOnlySpan<byte> hash = address.Hash; // 32 bytes

Using LiteClient

using TonSdk.Adnl;
using TonSdk.Adnl.LiteClient;

var client = new LiteClient(LiteClientOptions.GetFromUrl("https://ton-blockchain.github.io/global.config.json"));
await client.Connect();

var masterchain = await client.GetMasterchainInfo();
Console.WriteLine($"Last block: {masterchain.Last.Seqno}");

Using with Entity Framework Core

using TonSdk.Core;
using TonSdk.Core.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;

public class Wallet
{
    public int Id { get; set; }
    public Address Address { get; set; } // TON address stored efficiently
    public decimal Balance { get; set; }
}

public class MyDbContext : DbContext
{
    public DbSet<Wallet> Wallets { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // Binary storage (36 bytes) - recommended
        modelBuilder.Entity<Wallet>()
            .Property(e => e.Address)
            .HasAddressConversion<Wallet>();
    }
}
