How it works

Sniper flow

Load targets from config → query router for expected out → apply configured slippage → perform WBNB → TOKEN swap → emit tx hash/receipt → optionally notify via Telegram.

Copy‑Trader flow

Subscribe to pending mempool transactions → filter by leader wallets → detect router swap intents → mirror with your position sizing and caps → optionally notify.

Bundler flow

Read a sequence of routes from config → execute each respecting slippage/deadline settings → suitable base for multicall-style extensions.

Volume Bot flow

Loop on an interval → small buys → approve when needed → partial or full sells → repeat with built‑in rate limiting.
