Rug Detection Workflows

What a Rug Pull Is

A rug pull is when the people behind a token pull the value out from under holders — draining the liquidity pool, minting and dumping a flood of new tokens, or coding the contract so buyers can never sell. The name comes from pulling the rug out. Because permissionless chains let anyone deploy a token and open a market, rugs are common, especially among memecoins and freshly-launched tokens. The good news is that many rugs leave detectable fingerprints on-chain before or as they happen, and a consistent checking routine catches a large share of them.

The Handful of Signals That Matter Most

A few checks do most of the work. **Liquidity**: is the pool locked or owned by the deployer who can pull it? **Mint authority**: can the team create unlimited new tokens? **Holder concentration**: do a few wallets hold most of the supply, ready to dump? **Sellability**: can you actually sell, or is the contract a honeypot that only allows buying? **Ownership**: does one address retain dangerous privileges over the contract? Running these before touching a token filters out a large fraction of obvious traps.

• A rug pull extracts value via liquidity removal, infinite minting, or blocked selling
• Rugs are common on permissionless chains, especially with new memecoins
• Key signals: liquidity lock, mint authority, holder concentration, sellability, ownership
• Many rugs are detectable on-chain before you interact
