# Sol Trade SDK

A comprehensive Rust SDK for seamless interaction with Solana DEX trading programs. This SDK provides a robust set of tools and interfaces to integrate PumpFun, PumpSwap, and Bonk functionality into your applications.

## Project Features

1. **PumpFun Trading**: Support for `buy` and `sell` operations
2. **PumpSwap Trading**: Support for PumpSwap pool trading operations
3. **Bonk Trading**: Support for Bonk trading operations
4. **Event Subscription**: Subscribe to PumpFun, PumpSwap, and Bonk program trading events
5. **Yellowstone gRPC**: Subscribe to program events using Yellowstone gRPC
6. **ShredStream Support**: Subscribe to program events using ShredStream
7. **Multiple MEV Protection**: Support for Jito, Nextblock, ZeroSlot, Temporal, Bloxroute, and other services
8. **Concurrent Trading**: Send transactions using multiple MEV services simultaneously; the fastest succeeds while others fail
9. **Unified Trading Interface**: Use unified parameter structures for trading operations

## Installation

Clone this project to your project directory:

```bash
cd your_project_root_directory
git clone https://github.com/0xfnzero/sol-trade-sdk
```

Add the dependency to your `Cargo.toml`:

## Usage Examples

### 1. Event Subscription - Monitor Token Trading

#### 1.1 Subscribe to Events Using Yellowstone gRPC

```rust
use sol_trade_sdk::{
    event_parser::{
        protocols::{
            pumpfun::{PumpFunCreateTokenEvent, PumpFunTradeEvent},
            pumpswap::{
                PumpSwapBuyEvent, PumpSwapCreatePoolEvent, PumpSwapDepositEvent,
                PumpSwapSellEvent, PumpSwapWithdrawEvent,
            },
            bonk::{BonkPoolCreateEvent, BonkTradeEvent},
        },
        Protocol, UnifiedEvent,
    },
    grpc::YellowstoneGrpc,
    match_event,
};

async fn test_grpc() -> Result<(), Box<dyn std::error::Error>> {
    // Subscribe to events using GRPC client
    println!("Subscribing to GRPC events...");

    let grpc = YellowstoneGrpc::new(
        "https://solana-yellowstone-grpc.publicnode.com:443".to_string(),
        None,
    )?;

    // Define callback function to handle events
    let callback = |event: Box<dyn UnifiedEvent>| {
        match_event!(event, {
            BonkPoolCreateEvent => |e: BonkPoolCreateEvent| {

### 6. Custom Priority Fee Configuration

```rust
use sol_trade_sdk::common::PriorityFee;

// Custom priority fee configuration
let priority_fee = PriorityFee {
    unit_limit: 190000,
    unit_price: 1000000,
    rpc_unit_limit: 500000,
    rpc_unit_price: 500000,
    buy_tip_fee: 0.001,
    buy_tip_fees: vec![0.001, 0.002],
    sell_tip_fee: 0.0001,
};

// Use custom priority fee in TradeConfig
let trade_config = TradeConfig {
    rpc_url: rpc_url.clone(),
    commitment: CommitmentConfig::confirmed(),
    priority_fee, // Use custom priority fee
    swqos_configs,
    lookup_table_key: None,
};
```

## Supported Trading Platforms

- **PumpFun**: Primary meme coin trading platform
- **PumpSwap**: PumpFun's swap protocol
- **Bonk**: token launch platform (letsbonk.fun)

## MEV Protection Services

- **Jito**: High-performance block space
- **NextBlock**: Fast transaction execution
- **ZeroSlot**: Zero-latency transactions
- **Temporal**: Time-sensitive transactions
- **Bloxroute**: Blockchain network acceleration

## New Architecture Features

### Unified Parameter Structure

- **BuyParams**: Unified buy parameter structure
- **SellParams**: Unified sell parameter structure
- **Protocol-specific Parameters**: Each protocol has its own parameter structure (PumpFunParams, PumpSwapParams, BonkParams)

### Event Parsing System

- **Unified Event Interface**: All protocol events implement the UnifiedEvent trait
- **Protocol-specific Events**: Each protocol has its own event types
- **Event Factory**: Automatically identifies and parses events from different protocols

### Trading Engine

- **Unified Trading Interface**: All trading operations use the same methods
- **Protocol Abstraction**: Supports trading operations across multiple protocols
- **Concurrent Execution**: Supports sending transactions to multiple MEV services simultaneously
