Base Token Risk Check
x402op-
Use before buying or approving an unknown ERC-20 token on Base. Rule-based check straight from the chain, without AI - contract and proxy (upgradeable?), owner and whether it was renounced, risky owner functions in the bytecode (mint, pause, blacklist, fees, trading switches), owner share of supply and DEX liquidity on Uniswap V2/V3 and Aerodrome in USD. Returns ok, caution or avoid with reasons in under two seconds. Technical check, not investment advice.

From its own 402 answer at UTC. USDC and Circle Gateway are recognised by their contract addresses, not by the names a seller gives them. How payments are read
