🛠️ Usage Examples

📋 Example Usage

1. Create SolanaTrade Instance

You can refer to Example: Create SolanaTrade Instance.

// Wallet
let payer = Keypair::from_base58_string("use_your_payer_keypair_here");
// RPC URL
let rpc_url = "https://mainnet.helius-rpc.com/?api-key=xxxxxx".to_string();
let commitment = CommitmentConfig::processed();
// Multiple SWQOS services can be configured
let swqos_configs: Vec<SwqosConfig> = vec![
    SwqosConfig::Default(rpc_url.clone()),
    SwqosConfig::Jito("your uuid".to_string(), SwqosRegion::Frankfurt, None),
    SwqosConfig::NextBlock("your api_token".to_string(), SwqosRegion::Frankfurt, None),
    SwqosConfig::Bloxroute("your api_token".to_string(), SwqosRegion::Frankfurt, None),
    SwqosConfig::ZeroSlot("your api_token".to_string(), SwqosRegion::Frankfurt, None),
    SwqosConfig::Temporal("your api_token".to_string(), SwqosRegion::Frankfurt, None),
    SwqosConfig::FlashBlock("your api_token".to_string(), SwqosRegion::Frankfurt, None),
    SwqosConfig::Node1("your api_token".to_string(), SwqosRegion::Frankfurt, None),
    SwqosConfig::BlockRazor("your api_token".to_string(), SwqosRegion::Frankfurt, None),
    SwqosConfig::Astralane("your api_token".to_string(), SwqosRegion::Frankfurt, None),
];
// Create TradeConfig instance
let trade_config = TradeConfig::new(rpc_url, swqos_configs, commitment);
// Create SolanaTrade client
let client = SolanaTrade::new(Arc::new(payer), trade_config).await;

2. Configure Gas Fee Strategy

For detailed information about Gas Fee Strategy, see the Gas Fee Strategy Reference.

GasFeeStrategy::set_global_fee_strategy(150000, 500000, 0.001, 0.001);

3. Build Trading Parameters

For detailed information about all trading parameters, see the Trading Parameters Reference.

let buy_params = sol_trade_sdk::TradeBuyParams {
  dex_type: DexType::PumpSwap,
  input_token_type: TradeTokenType::WSOL,
  mint: mint_pubkey,
  input_token_amount: buy_sol_amount,
  slippage_basis_points: slippage_basis_points,
  recent_blockhash: Some(recent_blockhash),
  extension_params: Box::new(params.clone()),
  lookup_table_key: None,
  wait_transaction_confirmed: true,
  create_input_token_ata: true,
  close_input_token_ata: true,
  create_mint_ata: true,
  open_seed_optimize: false,
  durable_nonce: None,
};

4. Execute Trading

client.buy(buy_params).await?;

⚡ Trading Parameters

For comprehensive information about all trading parameters including TradeBuyParams and TradeSellParams, see the dedicated Trading Parameters Reference.

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.

📊 Usage Examples Summary Table

⚙️ SWQOS Service Configuration

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

• Jito: The first parameter is UUID (if no UUID, pass an empty string "")
• Other MEV services: The first parameter is the API Token

Custom URL Support

Each SWQOS service now supports an optional custom URL parameter:

// Using custom URL (third parameter)
let jito_config = SwqosConfig::Jito(
    "your_uuid".to_string(),
    SwqosRegion::Frankfurt, // This parameter is still required but will be ignored
    Some("https://custom-jito-endpoint.com".to_string()) // Custom URL
);

// Using default regional endpoint (third parameter is None)
let nextblock_config = SwqosConfig::NextBlock(
    "your_api_token".to_string(),
    SwqosRegion::NewYork, // Will use the default endpoint for this region
    None // No custom URL, uses SwqosRegion
);

URL Priority Logic:

• If a custom URL is provided (Some(url)), it will be used instead of the regional endpoint
• If no custom URL is provided (None), the system will use the default endpoint for the specified SwqosRegion
• This allows for maximum flexibility while maintaining backward compatibility

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 durable_nonce when trading.

🔧 Middleware System

The SDK provides a powerful middleware system that allows you to modify, add, or remove instructions before transaction execution. Middleware executes in the order they are added:

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

🔍 Address Lookup Tables

Address Lookup Tables (ALT) allow you to optimize transaction size and reduce fees by storing frequently used addresses in a compact table format. For detailed information, see the Address Lookup Tables Guide.

🔍 Nonce Cache

Use Nonce Cache to implement transaction replay protection and optimize transaction processing. For detailed information, see the Nonce Cache Guide.
