> I check your BTC address against ~55,000 known-bad
addresses — sanctions lists, hack databases, and
scam reports compiled from OpenSanctions and BTCAbuse.
> I find all the addresses in your wallet cluster using
the common-input heuristic. If you used 50 different
addresses from one wallet, I'll find them all.
> I check every counterparty your coins touched.
If any of them is flagged, I'll show you exactly
which UTXO, which transaction, and how much.
> Optionally, I'll expand one hop further — tracing
who your counterparties traded with — but I'm
honest about the limits of that scan.
> I give you a heads-up before you deposit coins
to a regulated exchange. That's all I do.
> I CANNOT trace through CoinJoin or Lightning
transactions. Those are designed to be private.
> I CANNOT do a full forensic investigation.
Chainalysis runs full nodes with years of
historical clustering data. I run in your
browser with a 500KB database.
> I CANNOT see addresses you only received to
but never spent from — CIH only works on
outgoing transactions.
> I CANNOT guarantee an exchange will accept
your coins. They run their own analytics
and can flag things I can't see.
> I do not store your address, track your IP,
or sell data to anyone. This all runs in
your browser.
