Where does this list come from?

Directly from OFAC's own SDN.CSV and ALT.CSV exports (sanctionslistservice.ofac.treas.gov), which are public-domain U.S. federal government works. Digital currency addresses live inside the free-text Remarks field on each SDN entry; this tool extracts them into a flat, sortable CSV.

How often is it updated?

Every download re-checks a shared cache with a 12-hour TTL against OFAC's live export, so the list is never more than 12 hours stale.

Is this a substitute for OFAC's own SDN search?

No. This is a convenience export of one field (published crypto addresses) for building or refreshing an offline screener. For authoritative sanctions compliance decisions, always confirm against OFAC's own SDN search tool and consult counsel.

Building an offline screener?

The ofac-wallet-screening-kit is a standalone CLI that screens names/addresses against a bundled OFAC snapshot, air-gapped, or refreshes live with --fetch — this CSV is the same underlying data, packaged as a ready-to-run tool.

Reading this list

Only entities where OFAC's own Remarks field discloses a digital-currency address are included — most SDN entries have no published address at all.
One entity can have multiple addresses across chains (labeled by symbol, e.g. XBT, ETH, USDT) — each address is its own row.
This is a convenience export for building or refreshing your own screening list, not a substitute for a real-time compliance decision. Always re-check a specific hit against OFAC's own search tool, and consult counsel for actual compliance determinations.

Free cap: 20 lookups per IP per day. Paid programmatic access removes the wall.
