Token & contract risk report (on-chain evidence)

Hand over a token contract address (and chain) and get one evidence-based on-chain risk report: whether the source is verified, holder concentration (top-1 / top-10 share of supply, distinguishing pools/contracts from wallets), and supply + market context, with a top-holders appendix. Evidence, never a 'safe' or 'scam' verdict - on-chain checks can't see off-chain rugs, so a clean report is not an endorsement. USDC (x402/MPP). Not cached.
