The sender and inflow look clean.
Pre-deal · go / no-go
Pre-Transaction Check
A fast, preventive screen of the sender and their funds before you accept a crypto payment. You get one thing: a clear go/no-go verdict on the sender’s address — with the reasoning — before the money lands on your wallet and becomes your problem.
The verdict
A clear traffic light
OK within limits — e.g. amount cap, extra payer documents.
Sanctioned, criminal or heavily dirty inflow.
Why our approach
Fast, preventive, explicit
Speed: an express verdict in hours, not days — because the decision to accept a payment is often needed now.
Preventive: we check BEFORE you receive — not untangle a freeze afterwards (that’s a separate service).
The same engine as an investigation — labels × behaviour × known-evil screening — in a fast format.
An explicit traffic-light verdict instead of a vague “looks ok”.
Who it’s for
Anyone about to be paid in crypto
Sellers
Selling a car, property or goods for USDT and want to vet the payer first.
Businesses & freelancers
Accepting crypto for services and can’t afford a frozen account.
OTC desks
Screening a counterparty’s address before settling a trade.
How we work
Eight stages, intake to verdict (E0–E7)
An express verdict takes hours (same or next business day); a deep check across many addresses and hops takes 1–2 days.
E0
Intake & express scoring
What’s the deal, the sender address, amount, urgency? A first on-chain look for an obvious stop-factor; we set express or deep.
E1
Deal inputs
The sender address(es), asset and network, amount, and context: what’s being paid for, how you know the counterparty, which channel.
E2
Pull sender data
Via TronGrid: the address profile (balance, age) and its full USDT transfer history, normalised.
E3
Attribution & known-evil screening
Key addresses run through labels (TronScan, Arkham, our DB) and checked against OFAC (TRON), the Tether blacklist and AML checkers.
E4
Behaviour & exposure
Address type (personal / exchange / mover / mixer / scam), the share of flagged inflow, walking back 2–3 hops from large or flagged sources.
E5
Context reconciliation
Does the on-chain match your story — amount, timing, purpose? Any sign the money comes “from the wrong place” or of counterparty pressure.
E6
Verdict & opinion
We set the traffic light and, for yellow, the acceptance conditions — amount cap, splitting, extra payer documents.
E7
Hand-over & DB update
We deliver the verdict, explain conditions and acceptance hygiene, and record the sender’s labels and observations.
The deliverable
One readable verdict
- The verdict on the first line — so you can decide immediately.
- Who the sender is by labels and behaviour, with confidence levels.
- Sanctions and criminal-link screening (OFAC, Tether blacklist, AML).
- Where the inflow comes from and what share of it is dirty — plus conditions if yellow.
Where we stop
Cases we decline at intake
Wanting “cover”
Accepting knowingly dirty or criminal money and making it look verified.
Faking the verdict
Asking us to fake the result or remove and hide red flags we found.
No sender address
With no access to the sender’s address there is nothing to check — we can only warn about the risks.
