🧠 What does this code do?
This code powers a trading bot that watches for opportunities to buy or sell crypto tokens very quickly—before most people even know a trade is happening.

It works in two modes:

✂️ 1. Sniping Mode
Purpose: Catch a newly launched token the moment it becomes available on a trading platform like PancakeSwap.

How: It watches the blockchain for new "liquidity pool" transactions (which make a token tradable), and buys the token instantly.

User Input: The user provides wallet info, token address, how much to buy, how much price slippage is okay, and gas settings (like transaction fees).

Database: Saves the settings and status to a database (so users can start/stop or review it later).

⚔️ 2. Front-Running Mode
Purpose: Monitor known wallets or trading bots to copy or beat their trades.

How: It watches real-time transaction data and, when it sees someone buying a token, tries to buy it faster or alongside them—usually to make a quick profit.

User Input: Similar wallet and trade info, but it also lets the user set limits like minimum and maximum trade size.

💾 Data and History
It saves all activity (what was bought or sold, when, and at what price) into a database.

It can reset or clear all this info with a few commands.

🔧 Tech Under the Hood
Uses Web3 and Ethers.js to connect to blockchain nodes.

Parses and decodes Ethereum transactions live.

Uses Uniswap & PancakeSwap routers (version 2 & 3) to actually make the trades.

Has helper functions for buying and selling tokens.

Can approve tokens for trading if not already done.

All actions can be triggered from a web interface (frontend), and the backend handles the heavy lifting.

🔒 Safety Note
It uses private keys to sign transactions automatically—so it must be secured carefully.
