Three lists, one call

OFAC SDN, EU Consolidated, UN sanctions. Not just OFAC — what CySEC actually inspects.

Audit trail built in

Every check timestamped with list version. Pull compliance reports for regulators in one click.

Batch screening

Onboarding day? Upload addresses. Screen hundreds in seconds, not hours of manual lookups.

Recognize yourself?

You're one inspection away from a compliance gap

You use Chainalysis free tier — it covers OFAC only. Where are your EU and UN screening records?
CySEC inspection notice arrived. Your audit trail has gaps you can't explain.
You asked Chainalysis or Elliptic for a quote and got a number with five zeros.
MiCA is live. Travel Rule obligations now include sanctions screening. Your current setup doesn't cover it.
You screen manually — copy-paste into OFAC search, then EU, then UN. Every. Single. Time.

Built for

Compliance teams at licensed CASPs

Operations Directors — your team needs multi-list screening. Enterprise vendors quote $10K+. ChainScreen delivers the same coverage at a fraction of the cost.

Your questions

We had the same ones

"Can $99 really replace Chainalysis?"

For sanctions screening — yes. Enterprise tools bundle analytics, monitoring, and risk scoring. If you only need list screening + audit trail (what CySEC inspects), you're paying for features you don't use.
"How current are the lists?"

Updated within 1 hour of source publication. Every update logged — your audit trail shows exactly which list version was used for each check.
"Where is my data?"

EU data centers only. All screening records stay in the EU. No data transfer outside — GDPR and CySEC compliant by default.
"What if I outgrow this?"

Export everything and upgrade to enterprise tools with your audit history intact. But most small CASPs never need more than this.
