πŸ†• What's new in 3.5.2

  • SWQoS submit latency: Sync serialize + buffer-pool hot path; format! body for single/batch submit (Bloxroute); avoid status clone in confirmation polling.
  • First-submit & 5-min idle: Immediate first ping + 30s keepalive; pool_max_idle_per_host=4 and pool_idle_timeout=300s (BlockRazor, Temporal, Node1, Astralane, Stellium) so submit reuses the same connection; ping consumes response body for connection reuse.
  • Docs: All SWQoS comments translated to English.

πŸ†• What's new in 3.5.1

  • SWQoS / executor: Updates to common SWQoS logic and trading executor.

πŸ†• What's new in 3.5.0

  • Performance: Hot-path timing only when logging; reduced clones (execute_parallel takes &[Arc<SwqosClient>]); shared HTTP client constants for SWQoS.
  • Code quality: Extracted validate_protocol_params for buy/sell; constants for instruction/account sizes and HTTP timeouts; prefetch and branch-hint comments.
  • Documentation: Bilingual (English + δΈ­ζ–‡) doc comments across execution, executor, perf, and swqos modules.

πŸ› οΈ Usage Examples

πŸ“‹ Example Usage

1. Create TradingClient Instance

You can refer to Example: Create TradingClient Instance.

Method 1: Simple (single wallet)

// 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::Bloxroute("your api_token".to_string(), SwqosRegion::Frankfurt, None),
];
// Create TradeConfig instance
let trade_config = TradeConfig::new(rpc_url, swqos_configs, commitment);

// Optional: customize WSOL ATA and seed optimization
// let trade_config = TradeConfig::new(rpc_url, swqos_configs, commitment)
//     .with_wsol_ata_config(true, true);  // create_wsol_ata_on_startup, use_seed_optimize

// Create TradingClient
let client = TradingClient::new(Arc::new(payer), trade_config).await;

Method 2: Shared infrastructure (multiple wallets)

For multi-wallet scenarios, create the infrastructure once and share it across wallets. See Example: Shared Infrastructure.

// Create infrastructure once (expensive)
let infra_config = InfrastructureConfig::new(rpc_url, swqos_configs, commitment);
let infrastructure = Arc::new(TradingInfrastructure::new(infra_config).await);

// Create multiple clients sharing the same infrastructure (fast)
let client1 = TradingClient::from_infrastructure(Arc::new(payer1), infrastructure.clone(), true);
let client2 = TradingClient::from_infrastructure(Arc::new(payer2), infrastructure.clone(), true);

2. Configure Gas Fee Strategy

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

// Create GasFeeStrategy instance
let gas_fee_strategy = GasFeeStrategy::new();
// Set global strategy
gas_fee_strategy.set_global_fee_strategy(150000, 150000, 500000, 500000, 0.001, 0.001);

3. Build Trading Parameters

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

// Import DexParamEnum for protocol-specific parameters
use sol_trade_sdk::trading::core::params::DexParamEnum;

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),
  // Use DexParamEnum for type-safe protocol parameters (zero-overhead abstraction)
  extension_params: DexParamEnum::PumpSwap(params.clone()),
  address_lookup_table_account: None,
  wait_transaction_confirmed: true,
  create_input_token_ata: true,
  close_input_token_ata: true,
  create_mint_ata: true,
  durable_nonce: None,
  fixed_output_token_amount: None,  // Optional: specify exact output amount
  gas_fee_strategy: gas_fee_strategy.clone(),  // Gas fee strategy configuration
  simulate: false,  // Set to true for simulation only
  use_exact_sol_amount: None,  // Use exact SOL input for PumpFun/PumpSwap (defaults to true)
};

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.

βš™οΈ 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 bloxroute_config = SwqosConfig::Bloxroute(
    "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 use the fetch_nonce_info function to get the latest nonce value, and use it as the durable_nonce when trading.

πŸ”§ 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

πŸ” 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.

πŸ” Durable Nonce

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

πŸ’° Cashback Support (PumpFun / PumpSwap)

PumpFun and PumpSwap support cashback for eligible tokens: part of the trading fee can be returned to the user. The SDK must know whether the token has cashback enabled so that buy/sell instructions include the correct accounts (e.g. UserVolumeAccumulator as remaining account for cashback coins).

  • When params come from RPC: If you use PumpFunParams::from_mint_by_rpc or PumpSwapParams::from_pool_address_by_rpc / from_mint_by_rpc, the SDK reads is_cashback_coin from chainβ€”no extra step.
  • When params come from event/parser: If you build params from trade events (e.g. sol-parser-sdk), you must pass the cashback flag into the SDK:
    • PumpFun: PumpFunParams::from_trade(..., is_cashback_coin) and PumpFunParams::from_dev_trade(..., is_cashback_coin) take an is_cashback_coin parameter. Set it from the parsed event (e.g. CreateEvent’s is_cashback_enabled or BondingCurve’s is_cashback_coin).
    • PumpSwap: PumpSwapParams has a field is_cashback_coin. When constructing params manually (e.g. from pool/trade events), set it from the parsed pool or event data.
  • The pumpfun_copy_trading and pumpfun_sniper_trading examples use sol-parser-sdk for gRPC subscription and pass e.is_cashback_coin when building params.
  • Claim: Use client.claim_cashback_pumpfun() and client.claim_cashback_pumpswap(...) to claim accumulated cashback.
