Api Endpoint

HALOWERK kettenwerk

Reads the transaction history of one wallet from a public block explorer index and groups it by kind of action. Classification follows the called contract and method, never the amount - a transfer to a known router is a swap, not a payment. Anything that cannot be backed by a method name stays in the category "unbekannt", which is a valid answer here: a large honest remainder beats an invented assignment. Limits: history comes from a public index available for Ethereum, Base, Arbitrum and Optimi
