## Installation

### Direct Clone

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`:

```toml
# Add to your Cargo.toml
sol-trade-sdk = { path = "./sol-trade-sdk", version = "0.5.4" }
```

### Use crates.io

```toml
# Add to your Cargo.toml
sol-trade-sdk = "0.5.4"
```

## Usage Examples

### Important Parameter Description

#### auto_handle_wsol Parameter

In PumpSwap, Bonk, and Raydium CPMM trading, the `auto_handle_wsol` parameter is used to automatically handle wSOL (Wrapped SOL):

- **Mechanism**:
  - When `auto_handle_wsol: true`, the SDK automatically handles the conversion between SOL and wSOL
  - When buying: automatically wraps SOL to wSOL for trading
  - When selling: automatically unwraps the received wSOL to SOL
  - Default value is `true`

#### lookup_table_key Parameter

The `lookup_table_key` parameter is an optional `Pubkey` that specifies an address lookup table for transaction optimization:

- **Purpose**: Address lookup tables can reduce transaction size and improve execution speed by storing frequently used addresses
- **Usage**: 
  - Can be set globally in `TradeConfig` for all transactions
  - Can be overridden per transaction in `buy()` and `sell()` methods
  - If not provided, defaults to `None`
- **Benefits**:
  - Reduces transaction size by referencing addresses from lookup tables
  - Improves transaction success rate and speed
  - Particularly useful for complex transactions with many account references

#### priority_fee Parameter

The `priority_fee` parameter is an optional `PriorityFee` that allows you to override the default priority fee settings for individual transactions:

- **Purpose**: Provides fine-grained control over transaction priority fees on a per-transaction basis
- **Usage**:
  - Can be passed to `buy()` and `sell()` methods to override the global priority fee settings
  - If not provided, defaults to `None` and uses the priority fee settings from `TradeConfig`
  - When provided, the `buy_tip_fees` array will be automatically padded to match the number of SWQOS clients
- **Benefits**:
  - Allows dynamic adjustment of priority fees based on market conditions
  - Enables different fee strategies for different types of transactions
  - Provides flexibility for high-frequency trading scenarios

#### About ShredStream

When using shred to subscribe to events, due to the nature of shreds, you cannot get complete information about transaction events.
Please ensure that the parameters your trading logic depends on are available in shreds when using them.

### 1. Event Subscription - Monitor Token Trading

See the example code in [examples/event_subscription](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/event_subscription/src/main.rs).

Run the example code:
```bash
cargo run --package event_subscription
```

### 2. Initialize SolanaTrade Instance

#### 2.1 SWQOS Service Configuration

When configuring SWQOS services, note the different parameter requirements for each service:

- **Jito**: The first parameter is UUID, if you don't have a UUID, pass an empty string `""`
- **NextBlock**: The first parameter is API Token
- **Bloxroute**: The first parameter is API Token  
- **ZeroSlot**: The first parameter is API Token
- **Temporal**: The first parameter is API Token
- **FlashBlock**: The first parameter is API Token, Add community TG admin [xyz_0xfnzero](https://t.me/xyz_0xfnzero) to get a free key and instantly speed up your trading (with tip refunds available)!
- **Node1**: The first parameter is API Token, Add the official TG support at https://t.me/node1_me to get a free key and instantly accelerate your trades! 

When using multiple MEV services, you need to use `Durable Nonce`. You need to initialize a `NonceCache` class (or write your own nonce management class), get the latest `nonce` value, and use it as the `blockhash` when trading.

#### 2.2 Creating SolanaTrade Instance

See the example code in [examples/trading_client](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/trading_client/src/main.rs).

Run the example code:
```bash
cargo run --package trading_client
```

### 3. PumpFun Trading Operations

#### 3.1 Sniping

See the example code in [examples/pumpfun_sniper_trading](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/pumpfun_sniper_trading/src/main.rs).

Run the example code:
```bash
cargo run --package pumpfun_sniper_trading
```

#### 3.2 Copy Trading

See the example code in [examples/pumpfun_copy_trading](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/pumpfun_copy_trading/src/main.rs).

Run the example code:
```bash
cargo run --package pumpfun_copy_trading
```

### 4. PumpSwap Trading Operations

See the example code in [examples/pumpswap_trading](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/pumpswap_trading/src/main.rs).

Run the example code:
```bash
cargo run --package pumpswap_trading
```

### 5. Raydium CPMM Trading Operations

See the example code in [examples/raydium_cpmm_trading](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/raydium_cpmm_trading/src/main.rs).

Run the example code:
```bash
cargo run --package raydium_cpmm_trading
```

### 6. Raydium AMM V4 Trading Operations

Run the example code:
```bash
cargo run --package raydium_amm_v4_trading
```

### 7. Bonk Trading Operations

#### 7.1 Sniping

See the example code in [examples/bonk_sniper_trading](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/bonk_sniper_trading/src/main.rs).

Run the example code:
```bash
cargo run --package bonk_sniper_trading
```

#### 7.2 Copy Trading

See the example code in [examples/bonk_copy_trading](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/bonk_copy_trading/src/main.rs).

Run the example code:
```bash
cargo run --package bonk_copy_trading
```

### 8. Middleware System

The SDK provides a powerful middleware system that allows you to modify, add, or remove instructions before transaction execution. This gives you tremendous flexibility to customize trading behavior.

See the example code in [examples/middleware_system](https://github.com/0xfnzero/sol-trade-sdk/tree/main/examples/middleware_system/src/main.rs).

Run the example code:
```bash
cargo run --package middleware_system
```

Middleware executes in the order they are added:

```rust
let middleware_manager = MiddlewareManager::new()
    .add_middleware(Box::new(FirstMiddleware))   // Executes first
    .add_middleware(Box::new(SecondMiddleware))  // Executes second
    .add_middleware(Box::new(ThirdMiddleware));  // Executes last
```

### 9. Custom Priority Fee Configuration

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

// Custom priority fee configuration
let priority_fee = PriorityFee {
    tip_unit_limit: 190000,
    tip_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,
};
```
