Contract Flags

by Token rug check: contract risk in Onchain & crypto

x402 APIPassing, checked 52 min ago

Smart contract risk check (Base, Arc): can the owner mint, pause, blacklist, change fees or upgrade the code? What can the people behind this contract do to holders? Pass ?chain=base|arc&address=0x... and we read its bytecode on chain (and the code behind a proxy): mint, pause, blacklist, change fees or taxes, cap wallets, switch trading off, upgrade the code. Plus proxy type, who owns it now (renounced or a live wallet or contract) and basic token data.
