Frozen accounts
One unexplained deposit
A single crypto-sourced payment you can't account for can freeze the account your whole business runs on.
Crypto payments for high-ticket trade
Stop turning away the buyers your competitors are quietly servicing.
Blackmarble helps precious-metals dealers — and other high-ticket businesses — accept crypto payments legally. You capture the sale, without risking a frozen account or an AML problem.
We coordinate the lawyers. We never touch your money.
The loss you don't see
Every crypto-ready buyer who walks is a sale someone else just closed.
The buyer is willing. You've already verified them. The deal still dies — because a second, redundant ID check at a crypto processor is enough friction to send a high-value buyer elsewhere.
Today — the buyer hits KYC twice and walks

Why DIY is the expensive option
Getting crypto wrong doesn't cost you a little. It costs you your banking.
These are the real risks — not manufactured panic. They are exactly why this isn't a job to wing.
AML exposure
The liability is yours
Accept funds you didn't screen and the obligation sits with you — not the buyer, not the processor.
Dirty deposits
You can't prove it's clean
Without source-of-funds checks on the way in, you have no record to show when it's the one thing that matters.
De-risking
Banking you can't get back
Once a bank decides you're a risk, regaining access is slow, costly, and sometimes simply not possible.
How we do it
Capture the upside. Remove the existential risk.
A done-with-you process that keeps you firmly on the right side of the line — and keeps your bank and auditor onside.
01
Reuse the KYC you've done
Your already-verified customer doesn't get sent through a second identity gauntlet. The friction that loses the sale disappears.
02
Screen the funds
Source-of-funds and AML checks on every incoming payment — documented, so the answer exists before the question is ever asked.
03
Settle clean fiat
Money flows through your own — or a licensed partner's — rails. We never hold it and we never transmit it.
04
Keep audit-ready records
Every transaction documented and reconcilable, so a banking or compliance review is a non-event.
The backbone
We bring the lawyers. You stay on the right side of the line.
- Vetted counsel, coordinated. We bring qualified legal partners in — and never offer legal opinions ourselves.
- We never hold or move your funds. Money stays in your accounts, keeping us cleanly on the service-provider side.
- Proper footing. A real entity, clear engagement terms, and professional indemnity insurance behind every engagement.
- Trust is the whole point. Real risks, honestly handled — never invented fear to sell a service.
