QvaPay Sentinel · sanctions & regime screening

Screen every regime-linked party — not just OFAC's list

QvaPay Sentinel is a public sanctions-screening API — live at sdn.qvapay.com — that checks names, entities, and crypto wallets against OFAC's SDN list. And it goes past what OFAC requires: it adds its own Cuban-regime data pools Washington has never designated, so a regime-linked party gets caught before it ever lands on a sanctions list.

Why screening isn't optional

OFAC sanctions are strict-liability: a single payment to a blocked party is a violation even if you never knew. The duty covers names, entities, and crypto addresses, and reaches any company owned ≥50% by a blocked party (the 50% rule). In Cuba the real exposure is regime nexus — and many regime operators are on no OFAC list yet.

What OFAC requires you to screen

Names

Individuals on the SDN list — including aliases, transliterations and spelling variants.

Entities

Blocked companies and organizations, plus anything owned ≥50% by them.

Crypto addresses

Blocked digital-currency wallets — exact, case-insensitive match.

How QvaPay goes beyond OFAC

Four data pools in one call. OFAC is the floor; the three regime pools are the edge — they catch affiliates OFAC hasn't listed yet.

OFAC SDN

The U.S. Treasury's Specially Designated Nationals list — names, entities, and the blocked crypto addresses OFAC publishes across many currencies. What every U.S. person is legally required to screen.

Cuba Restricted List

The State Department's list of entities under the control of, or acting for, the Cuban military, intelligence or security services — GAESA and its subsidiaries first among them. Since September 30, 2026 the prohibition reaches indirect transactions too, so the list is screened on every leg of a payment, not just against the counterparty.

PCC Directorio

The leadership directory of the Cuban Communist Party (Partido Comunista de Cuba) — regime officials OFAC has not individually designated.

ANPP Diputados

Every deputy of the National Assembly of People's Power (Asamblea Nacional del Poder Popular), sourced from the regime's own roster at parlamentocubano.gob.cu.

FHRC Represores

Documented regime repressors compiled by the Foundation for Human Rights in Cuba — the people enforcing repression, whether or not Washington has sanctioned them yet. FHRC has run this public database since 2018, sorted into categories from direct violence to the officials who sign the orders, with a published correction channel; 1,695 case files as of August 2026.

Name screening is fuzzy — it tolerates typos, word order, accents and transliterations (search “lazaruz grupo,” find Lazarus Group). Crypto matching is exact. Lists refresh in real time — Sentinel pulls directly from OFAC's published updates and re-screens on every list change.

What Sentinel covers

✓ Broader coverage than OFAC alone: sanctions + three regime pools in one call.
✓ Names, entities and crypto addresses — all three, not just names.
✓ Fuzzy matching that survives typos, accents and transliterations.
✓ Lists refresh in real time — Sentinel pulls directly from OFAC's published updates and re-screens on every list change; built by a Cuban team that knows the terrain.

Screen every blocked party, entity and crypto address — at and beyond OFAC.
