Sync supported DEX IDLs from bitquery/solana-idl-lib, upgrade protocol builders, and keep trade submission hot paths free of RPC query calls.
Include exact-output coverage, token-account setup fixes for WSOL and stable pairs, and low-latency transaction build improvements.
- Rename wait_transaction_confirmed to wait_tx_confirmed (params, lib, docs, examples)
- SDK timing: use [SDK][provider] style with fixed-width labels; add newline before block
- Move print_sdk_timing_block to common::sdk_log; unify SWQOS_LABEL_WIDTH
- SWQOS submitted/failed: aligned [Provider] labels via log_swqos_submitted/submission_failed
- Extract short error message from JSON (message/data) or quoted string; prefix with 'error: '
- Format elapsed as 'X.XXXX ms' or 'X.XXXX µs' (4 decimals, space before unit); use comma before error
- Add SwqosType::as_str() for zero-allocation log labels; only parse JSON when input starts with '{'
Made-with: Cursor
- 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
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.
- 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
- 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
- recent_blockhash is now Option<Hash> instead of Hash
- nonce_account and current_nonce fields replaced with durable_nonce: Option<DurableNonceInfo>
- Add nonce_account and current_nonce to trade parameters
- Remove hardcoded NonceCache dependency from nonce_manager
- Update examples and documentation for new nonce usage
- Fix nonce documentation errors and improve clarity
- feat(gas): add comprehensive gas fee strategy management system
* Implement GasFeeStrategyType with Default/LowTipHighCuPrice/HighTipLowCuPrice strategies
* Add dynamic gas fee configuration per SWQOS service and trade type
* Integrate arc-swap for thread-safe strategy updates
- docs: restructure documentation with dedicated guides
* Add ADDRESS_LOOKUP_TABLE.md/CN.md for lookup table configuration
* Add NONCE_CACHE.md/CN.md for nonce management documentation
* Add TRADING_PARAMETERS.md/CN.md for comprehensive parameter guides
* Simplify main README.md with focused overview
- refactor: update all examples with new gas fee strategy integration
* Modernize 14 trading examples with consistent parameter handling
* Improve error handling and configuration management
* Enhance parallel trading implementation
