Token Risk Check
by Agent Utility Suite in Onchain & crypto
Is this token safe to buy or accept? For an ERC-20 on Base or Ethereum: owner powers from its code (mint, blacklist, fees, pause, trading switch, limits), upgradeable proxy, renounced ownership, DEX liquidity (Uniswap v2/v3, Aerodrome vs WETH/USDC with USD estimate) and OFAC screening of token and owner. Verdict, score, reasons. $0.01 USDC per call.
