TradeInfo extensions in src:
Updated src/engine/transaction_parser.rs TradeInfoFromToken to include Raydium Launchpad fields seen in shred-stream: platform_config, additional_account_1..3. Filled these as None for existing parsers.
Raydium additional accounts support:
Updated src/dex/raydium_launchpad.rs:
build_swap_from_parsed_data now reads platform_config override and attaches any additional_account_* to the instruction accounts.
Extended create_buy_accounts and create_sell_accounts to accept optional platform config and extra accounts and append them in order after the canonical 15 Raydium accounts.
Shredstream sell listener:
Added src/services/shred_seller.rs: subscribes to shredstream entries and, on SELL-only instructions:
Pump.fun: detects SELL and submits a sell operation to the existing ParallelTransactionProcessor.
Raydium Launchpad: detects SellExactIn, extracts pool_id, mint, platform_config, and additional accounts (indexes 15..17), and submits to the same processor.
Wired the service into src/services/mod.rs as pub mod shred_seller;.
Startup wiring:
In src/engine/copy_trading.rs, after creating ParallelTransactionProcessor, I start the shredstream sell listener in a background task. This runs alongside the gRPC stream:
gRPC: continue to handle buys and existing sells.
Shredstream: adds a parallel SELL path intended to front-run sells.
Dependencies:
Added to Cargo.toml:
solana-stream-sdk = "0.5.1", solana-entry = "=2.2.1"
local parsers: pump_interface and raydium_launchpad_interface from shred-stream/parsers/* so we can deserialize instructions like shred-stream does.
How to run:
Set SHREDSTREAM_URL if you need a custom endpoint; default is a placeholder wss://ny1.rpcpool.com/shredstream.
Build and run as before; the shredstream sell front-runner starts automatically with the gRPC bot.
Notes:
The gRPC path remains unchanged for buying and selling, so you can still compare performance.
Raydium Launchpad now honors additional accounts provided from shredstream parsing when present.
Added shredstream-powered sell listener (src/services/shred_seller.rs) and started it from src/engine/copy_trading.rs to front-run sells while keeping gRPC logic untouched.
Extended TradeInfoFromToken and src/dex/raydium_launchpad.rs to support Raydium Launchpad additional accounts and optional platform_config like in shred-stream/src/shred_stream.rs.
