Deterministic risk screen of an ERC-20 token from on-chain bytecode and metadata
Deterministic risk screen of an ERC-20 token from on-chain bytecode and metadata, no third-party risk API. Flags privileged or abuse capabilities: blacklist/freeze, owner mint, pausable transfers, upgradeable proxy and a privileged owner, plus tokens missing symbol/decimals or code. Returns each flag with a severity, a 0-100 score and a verdict. Reads live on-chain data with automatic endpoint fallback.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
