🆕 Funding provenance in one call.

🆕 Funding provenance in one call. Traces a Base wallet back to its EARLIEST transaction and resolves who first funded it: a recognized exchange/bridge (real on-ramp, lower risk), an anon EOA (possible sybil/burner — trace the cluster), or a contract. Returns the first funder, whether it's a contract or EOA, the initial value, and wallet age. The sybil/origin screen no other Base tool gives — the counterparty check before you transact. wallet= required. Not financial advice.Overview
