PumpCheck

blockchain

Serving

What can go wrong with a memecoin now, on Solana, Base and Robinhood Chain: mint and freeze authority, Token-2022 hooks, owner powers, a simulated buy and sell for honeypots and taxes, LP burn, holders and early buyers. Each check is definitive or heuristic, unknown never counts as a pass, and a verdict comes with plain flags. POST /v1/check with 1 to 10 tokens. Not financial advice.
