Pre-buy token check

Token Security Scanner

Paste any token contract before you buy — live on 6 chains (Base, BNB Chain, Ethereum, Optimism, Polygon, Arbitrum). A simulated buy-and-sell on each chain's main DEXes shows whether it can actually be sold; name/symbol impersonation and mint-authority checks plus 1B+ BA entity labels cover the rest.
