Compares the runtime bytecode of two Ethereum contracts you name
Compares the runtime bytecode of two Ethereum contracts you name: the share of shared PUSH4 function selectors (Jaccard) and the cosine similarity of their opcode frequencies, combined into one 0 to 1 score with a SIMILAR, PARTIAL or DIFFERENT label. It compares two addresses only; it has no database of known scam or exploit templates, so it cannot say a contract is a known clone.
