- 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

- 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
Add Meteora DAMM V2 trading protocol with instruction builder, type definitions, and fixed_output_token_amount parameter for precise output control. Update all examples and documentation.
This refactoring migrates protocol-related type definitions from solana-streamer-sdk to local modules:
- Add local type files: bonk_types.rs, pumpswap_types.rs, raydium_amm_v4_types.rs, raydium_cpmm_types.rs
- Add BorshDeserialize support for all types
- Refactor BondingCurveAccount to support Borsh deserialization
- Update import paths across all protocol utility modules (bonk, pumpfun, pumpswap, raydium)
- Refactor trade parameter construction methods from event objects to individual parameters for better flexibility
- Fix nonce_cache import path to use local SolanaRpcClient
- Upgrade Solana dependencies from 2.3.x to 3.0.0 series
- Upgrade solana-streamer-sdk from 0.4.13 to 0.5.0
- Upgrade yellowstone-grpc from 8.0.0 to 9.0.0
- Add new SPL token utility modules (spl_token.rs, spl_token_2022.rs,
spl_associated_token_account.rs)
- Remove deprecated gRPC protocol definitions (protos/ directory)
- Remove event_subscription example and update all example dependencies
- Update README documentation to reflect v2.0.0 changes
- Refactor imports to use new dependency structure across examples
BREAKING CHANGES:
- Solana SDK upgraded to 3.0.0 with API changes
- Removed gRPC protocol definitions
- Updated import paths for SPL token operations
- Bump version from 1.2.0 to 1.2.1
- Change trade methods return type from Signature to (bool, Signature)
- Improve parallel execution error handling and status tracking
- Update CLI examples to match new API interface
- Enhance transaction success/failure reporting capabilities
Breaking Change: Trade API now returns tuple (success_status, signature)
- Bump version to 1.2.0
- Remove TradeSwapParams to simplify API structure
- Add TradeTokenType enum supporting SOL/WSOL/USD1 tokens
- Standardize parameter naming: sol_amount → input_token_amount, token_amount → input_token_amount
- Refactor account management parameters: create_wsol_ata → create_input_token_ata etc.
- Update all example code to use new API
- Synchronize English and Chinese documentation
BREAKING CHANGE:
- Removed TradeSwapParams struct
- Modified field names in TradeBuyParams and TradeSellParams
- Existing code needs migration to use new parameter structure
- Version bump: upgrade from 1.0.2 to 1.1.0
- Add TradeSwapParams struct for universal token-to-token swapping
- Update bonk_copy_trading example to use new swap method instead of buy/sell
- Expand trading parameters documentation with TradeSwapParams details
- Fix SOL_TOKEN_ACCOUNT constant definition
- Add USD1 token support (Bonk protocol only)
- Enhance account management and optimization options for token swaps
- Merge BuyParams and SellParams into unified SwapParams structure
- Add USD1 token pool support with related constants and configurations
- Refactor trade executor by combining buy_with_tip and sell_with_tip into swap method
- Update all protocol instruction builders to support new parameter structure
- Standardize ATA creation/closing parameter naming conventions
- Update example code to use new API interfaces
- Optimize trading logic with automatic direction detection based on input token type
- Change recent_blockhash from required to optional parameter
- Replace separate nonce_account and current_nonce with unified durable_nonce
- Update all examples and documentation to reflect API changes
- Improve nonce cache usage pattern for better developer experience
BREAKING CHANGE: TradeBuyParams and TradeSellParams API has changed
