marketpulselab/solana-rug-checker-bot

This is a monitoring bot that watches Solana cryptocurrency tokens for warning signs that a project might be a rug pull, where the creators abandon the token and run off with investors' money. It focuses on newly launched tokens showing up on Pump.fun and Meteora, two platforms where new Solana memecoins are frequently created and traded. The bot checks several things in one pass: whether the token's mint and freeze authority are still under the creator's control, which would let them mint more tokens or freeze holders at will, how concentrated the token supply is among a small number of holders, and whether the token can actually be traded through Jupiter, a token swap aggregator on Solana. It combines these checks into a single readable assessment and sends alerts to a Telegram chat in plain language rather than raw technical output. The README is honest about the tool's limits. It describes the checks as heuristics, meaning educated guesses based on patterns, not guarantees that a token is safe or unsafe. It notes that the public data sources it depends on can be unreliable or rate limited, and that it does not attempt to judge things like social media hype or sudden supply changes, since those fall outside what it can mechanically audit. The README also states plainly that this is not financial advice. Setup involves cloning the repository, installing dependencies with npm, and filling in a configuration file with a Solana RPC connection, a Telegram bot token, and the chat you want alerts sent to. It can run continuously on a small server or be triggered for a single check. The project is written in TypeScript using Solana web3 libraries, and is released under the MIT license.
