PumpFun Sniper Trading

中文

Uses sol-parser-sdk Yellowstone gRPC and selects creator-first-buy events (is_created_buy). Event fields are mapped into PumpFun params, including quote reserves, token program, cashback, and mayhem state, before one buy/sell flow.

This is a live-transaction template. Set PRIVATE_KEY, RPC_URL, GRPC_ENDPOINT, optional GRPC_AUTH_TOKEN, target policy, amounts, and fees.

export RPC_URL=https://your-rpc.example
export GRPC_ENDPOINT=https://your-yellowstone.example
cargo run --package pumpfun_sniper_trading

The current source creates SolanaTrade and fetches blockhash inside event handling. For production latency, initialize both before subscription as shown in the low-latency guide. Deduplicate signatures and refresh state before delayed sells.
