How it works

Three steps to a formal document.

  1. Step 1

    Enter an address – or invoice a client

    Check any wallet, or send a payment link. We detect the chain automatically across 9 networks.

  2. Step 2

    We screen it

    Sanctions lists, AML scoring, mixer and darknet exposure, and source-of-funds – in seconds.

  3. Step 3

    Get a formal report

    A clean, timestamped PDF you can present as an official record – verifiable by anyone.
