Overview

The on-chain immune attestation of one Arc token, read from the ImmuneAttestations contract on Arc mainnet ([redacted]): the grade (A/B healthy, C watch, D sick, F infected, ? unproven), the sha256 evidenceHash it rests on, the block and time it was written. Read this BEFORE you buy a token: it is a public chain record, not a fresh check (a fresh one is /api/x402/arc-immune). An attestation is written when a deep check is bought, so a token nobody has checked says attested:false, which is not a clean bill of health. A failed chain read is reported as failed, never as no attestation.
