- 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.
- 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
