- Introduce DexParamEnum to replace Dex enum for protocol parameters
- Simplify TradeConfig::new() to accept only 3 essential parameters
- Update all examples to use new DexParamEnum API
- Optimize executor and params modules
- Remove deprecated wsol_use_seed and mint_use_seed parameters
- Fix fast_fn module exports
Improve error message extraction in poll_transaction_confirmation to:
- Collect multiple error messages instead of stopping at the first one
- Add support for "Program log: Error: " format in addition to "Error Message: "
- Concatenate multiple errors with semicolon separator for comprehensive error reporting
- Add TradeError struct with code, message, and instruction fields
- Enhance poll_transaction_confirmation to extract detailed error info from logs
- Change buy/sell return type from Option<anyhow::Error> to Option<TradeError>
- Add solana-transaction-status-client-types dependency
- Remove unused parallel.rs module
- Define minimum tip constants for each SWQOS provider (JITO, NextBlock, Node1, etc.)
- Add dynamic filtering in execute_parallel to skip transaction building when tip is below provider's minimum
- Add missing SWQOS_ENDPOINTS_ASTRALANE constant
- Ensure SWQOS clients are always initialized but transactions are conditionally built based on current tip amount
- Add update_buy_tip() method to dynamically update buy tip while keeping other parameters unchanged
- Add update_sell_tip() method to dynamically update sell tip while keeping other parameters unchanged
- Enable simple one-line tip updates for all configured SWQOS providers
- Support percentage-based dynamic tip calculation in trading bots
- Split use_seed_optimize parameter into two independent configs:
* wsol_use_seed: controls seed optimization for WSOL ATA operations (default: false)
* mint_use_seed: controls seed optimization for other mint ATA operations (default: true)
- Refactor TradeConfig to accept all parameters in new() constructor
- Remove deprecated builder methods (with_seed_config, with_wsol_ata_config)
- Add wsol_use_seed and mint_use_seed fields to SwapParams
- Remove open_seed_optimize field from SwapParams
- Update all instruction builders to use correct seed parameter:
* Use params.wsol_use_seed for WSOL token operations
* Use params.mint_use_seed for other token operations
* Fix token type detection in bonk.rs, raydium_cpmm.rs, and raydium_amm_v4.rs
to properly select wsol_use_seed when dealing with WSOL tokens
- Update wsol_manager functions to accept is_use_seed parameter:
* handle_wsol()
* close_wsol()
* create_wsol_ata()
* wrap_sol_only()
* wrap_wsol_to_sol()
- Add wrap_wsol_to_sol() function with smart temporary account selection:
* If source is seed-created, use normal ATA for temp account
* If source is normal ATA, use seed ATA for temp account
* Prevents address conflicts while optimizing performance
This provides fine-grained control over seed optimization strategies,
allowing different configurations for WSOL and other tokens.
Major changes:
- Bump version from 3.3.1 to 3.3.2
- Add token_program field to PumpFun trading parameters
- Support explicit token_program passing for better TOKEN_PROGRAM_2022 compatibility
- Update all example code to pass token_program parameter
- Optimize token program determination logic from auto-inference to explicit parameter
Major changes:
- Bump version from 3.3.0 to 3.3.1
- Update GasFeeStrategy API with min/max data size parameters
- Enhance trade return values with Optional<anyhow::Error> in buy/sell/sell_percent methods
- Fix PumpFun Mayhem mode fee recipient constant bug
- Standardize gas fee strategy parameters across all examples
- Update all examples to handle new triple return value (bool, Signature, Option<Error>)
- Remove open_seed_optimize parameter from TradeBuyParams and TradeSellParams structs
- Add global use_seed_optimize configuration in TradeConfig with default value true
- Add create_wsol_ata_on_startup configuration in TradeConfig with default value true
- Implement automatic WSOL ATA creation and verification on SDK initialization
- Add with_wsol_ata_config() builder method to TradeConfig for custom WSOL settings
- Update all examples to remove open_seed_optimize parameter usage
- Update documentation (README, TRADING_PARAMETERS) to reflect new configuration approach
- Upgrade package version from 3.1.7 to 3.2.0
Breaking Changes:
- open_seed_optimize parameter removed from trade parameters (now global setting)
- Seed optimization is now enabled by default for all operations
- Add `simulate` parameter to TradeBuyParams and TradeSellParams for transaction simulation
- Add `close_mint_token_ata` parameter to TradeSellParams for closing mint token ATA
- Implement simulate_transaction function to validate transactions without blockchain submission
- Update all examples to include new parameters (simulate: false, close_mint_token_ata: false)
- Add comprehensive documentation for transaction simulation feature
- Show detailed simulation output including logs, compute units, and errors
- Print timing metrics in English for better international compatibility
Remove NonceCache singleton pattern and replace with fetch_nonce_info function
that directly fetches nonce information from RPC. This simplifies the API by
eliminating cache initialization and state management, making it easier for
users to manage durable nonces.
Replace the global AddressLookupTableCache with a direct fetch function to simplify address lookup table management. This change improves code maintainability by removing global state and makes the API more explicit.
Key changes:
- Remove AddressLookupTableCache and AddressLookupManager
- Add new fetch_address_lookup_table_account function
- Update TradeBuyParams and TradeSellParams to use AddressLookupTableAccount instead of Pubkey
- Update all examples to use the new direct fetch approach
- Update documentation to reflect the simplified workflow
