Method and rigour
Check how they verify a token: contract address on Etherscan, tokenURI resolution, IPFS CID pinning checks, ERC-721 versus ERC-1155 mint records, and reverse image searches for copyminting.
Evidence to listen for
- Follows and can justify an established methodology
- Understands contamination, bias, and chain of custody as they apply to the field
- Knows the limits of their techniques and says so
- Documents procedure so results are reproducible and defensible
Five-point scoring guide
Careless method; unaware of contamination, bias, or procedural integrity.
Knows procedures but applies them inconsistently; gaps in documentation.
Sound standard practice; less certain outside familiar techniques.
Rigorous and well documented; understands the limits of each method.
Walks through a repeatable verification sequence tying contract bytecode, mint transaction, metadata hash and creator wallet to a single provenance chain.
