sol_amount	u64	✅	Amount of SOL to spend (in lamports)
slippage_basis_points	Option<u64>	❌	Slippage tolerance in basis points (e.g., 100 = 1%, 500 = 5%)
recent_blockhash	Option<Hash>	❌	Recent blockhash for transaction validity
extension_params	Box<dyn ProtocolParams>	✅	Protocol-specific parameters (PumpFunParams, PumpSwapParams, etc.)

Advanced Configuration Parameters

Parameter	Type	Required	Description
lookup_table_key	Option<Pubkey>	❌	Address lookup table key for transaction optimization

TradeSellParams

The TradeSellParams struct contains all parameters required for executing sell orders across different DEX protocols.

Basic Trading Parameters

Parameter Categories

🎯 Core Trading Parameters

These parameters are essential for defining the basic trading operation:

• dex_type: Determines which protocol to use for trading
• mint: Specifies the token to trade
• sol_amount (buy) / token_amount (sell): Defines the trade size
• recent_blockhash: Ensures transaction validity

⚙️ Transaction Control Parameters

These parameters control how the transaction is processed:

• slippage_basis_points: Controls acceptable price slippage
• wait_transaction_confirmed: Controls whether to wait for confirmation

🔧 Account Management Parameters

These parameters control automatic account creation and management:

• create_wsol_ata: Automatically wrap SOL to wSOL when needed
• close_wsol_ata: Automatically unwrap wSOL to SOL after trading
• create_mint_ata: Automatically create token accounts

🚀 Optimization Parameters

These parameters enable advanced optimizations:

• lookup_table_key: Use address lookup tables for reduced transaction size
• open_seed_optimize: Use seed-based account creation for lower CU consumption

🔄 Optional Parameters

When you need to use durable nonce, you need to fill in this parameter:

• durable_nonce: Durable nonce information containing nonce account and current nonce value

Important Notes

🌱 Seed Optimization

When open_seed_optimize: true:

• ⚠️ Warning: Tokens purchased with seed optimization must be sold through this SDK
• ⚠️ Warning: Official platform selling methods may fail
• 📝 Note: Use get_associated_token_address_with_program_id_fast_use_seed to get ATA addresses

💰 wSOL Account Management

The create_wsol_ata and close_wsol_ata parameters provide granular control:

• Independent Control: Create and close operations can be controlled separately
• Batch Operations: Create once, trade multiple times, then close
• Rent Optimization: Automatic rent reclamation when closing accounts

🔍 Address Lookup Tables

Before using lookup_table_key:

• Initialize AddressLookupTableCache to manage cached lookup tables
• Lookup tables reduce transaction size and improve success rates
• Particularly beneficial for complex transactions with many account references

📊 Slippage Configuration

Recommended slippage settings:

• Conservative: 100-300 basis points (1-3%)
• Moderate: 300-500 basis points (3-5%)
• Aggressive: 500-1000 basis points (5-10%)

🎯 Protocol-Specific Parameters

Each DEX protocol requires specific extension_params:

• PumpFun: PumpFunParams
• PumpSwap: PumpSwapParams
• Bonk: BonkParams
• Raydium CPMM: RaydiumCpmmParams
• Raydium AMM V4: RaydiumAmmV4Params

Refer to the respective protocol documentation for detailed parameter specifications.
