Source-of-funds tracing: POST a Base address, traces its earliest inbound funding (native ETH + ERC20) back up to N hops to find the first funder and ultimate origin. Stops at a labeled exchange or bridge (a KYC'd origin) or when no inbound exists. Returns the funding chain with labels, blocks, timestamps and amounts. For AI agent due diligence, sybil/cluster detection, source-of-funds and AML checks. Not financial advice. Accepts payment on Base or Solana — either network works.
