## Terms

On-chain facts read from Base's public RPC, provided as is, with no warranty of accuracy, completeness or fitness for a purpose. A contract can answer these reads dishonestly. Nothing here says a token is safe; honeypots, sell taxes, liquidity and holder concentration are not checked. Not financial or investment advice and not affiliated with Base or Coinbase.
