Most rugs leak the same on-chain tells before the floor drops. Here are nine you can check in under a minute — the same signals an automated rug-screen runs on every launch.
A "rug pull" is when a token's creator drains its liquidity or dumps a hidden supply, collapsing the price to zero. On high-velocity launchpads like pump.fun, hundreds launch per hour and the majority fail. You cannot eliminate the risk, but you can refuse the launches that wear their intent on-chain. Run this checklist before any entry.
If the liquidity pool tokens sit in the deployer's wallet, they can pull the pool at any moment. Look for locked or burned LP. One caveat specific to pump.fun: the bonding-curve LP is locked by the protocol by design, so "LP locked" alone is weak signal there — weigh it alongside the other flags, not on its own.
The single cleanest kill-signal: if the creator's holding has gone to zero, the dev has already sold their entire allocation. In on-chain studies this pattern is overwhelmingly associated with rugs. No narrative beats a dev who already left.
Some contracts let you buy but block or tax selling to death. A honeypot or sky-high sell tax means you are liquidity, not a trader. Token-security scanners flag transfer hooks, non-transferable flags and asymmetric taxes — never skip this check on EVM tokens especially.
Duplicate name, symbol or image of a token that is already running is a copycat fishing for mistaken buys. A real launch has its own identity. If it is impersonating something, treat it as hostile.
No checklist makes a memecoin safe — they are high-risk by nature. The goal is to raise the floor: cut the launches that are engineered to fail, so the ones you do touch have a fighting chance. That is exactly what an automated rug-screen does on every signal, at machine speed, before it ever reaches you.
BLOCKCHAIN44 screens every launch across six chains — mint, freeze, LP, bundles, honeypots and dev-dump signals — and only broadcasts what clears the gate. Free, non-custodial, you keep your keys.
