DESCRIPTION

Wallet label / address tagger / known-address lookup / EOA-vs-contract check / deployer tracer. Best-effort labelling for any EVM address against an in-handler dictionary of well-known CEX hot/cold wallets, DEX routers, NFT marketplaces, popular MEV bots, bridges, and stablecoins. Etherscan v2 'getcontractcreation' adds is_contract + deployer for unknown contracts. Returns label, category, and the source of the match.
