Screening Engine

Screen every address.
Block every threat.

Every sender and receiver address runs against OFAC SDN, internal threat labels, and mixer registries before the transfer clears. Sub-millisecond lookups. Fail-closed by design.

Screening Engine

Three data sources. One logged verdict.

Veris cross-references every blockchain address against sanctions lists, threat intelligence feeds, and behavioral signatures. The screening engine classifies risk, investigates patterns, and generates filings autonomously.

How it works

From address to verdict in six checks.

Every transfer flows through these six checks in sequence. Match triggers an immediate hold; clear continues to risk scoring.

01·Capture

Address capture

Every sender and receiver address extracted at block confirmation. Addresses normalize to lowercase checksummed format.
4 indexer processes
02·Lookup

List lookup

Each address queries OFAC SDN XML, internal threat labels, and the mixer registry. Redis caches results after first hit.
