dappgrade

Pre-transaction health and safety verdicts for onchain apps, by contract address.

Before an agent transacts with a dApp, ask what dappgrade observed: ok / caution / avoid / unknown — each carrying the coverage it rests on, so a partial result is never mistaken for a clean bill of health. unknown is a real, free answer: never infer safety from the absence of a rating.

Tools

• get_score — verdict for a (chain, address), with score, coverage, tier, flags and per-dimension sub-scores. Paid: 0.01 USDC via x402 on Base. Chain accepts an id (8453), CAIP-2 (eip155:8453), or a name (base).
• get_universe — every dApp covered, with current scores and coverage. Free.
• get_methodology — the rubric: tiers, three-state checks (pass / fail / not_reached), and the verdict model. Free.

Addresses resolve through frontend→contract mappings harvested by driving real dApps through real wallet flows. Where an address is shared across apps (routers, Permit2), every candidate is returned rather than a silent pick.
