AI DECISIONS — OFAC SDN crypto addresses (primary-source TagPack)

949 cryptocurrency addresses designated on the US Treasury OFAC Specially Designated Nationals (SDN) list, unified by the open-source openlabels attribution pipeline and emitted in GraphSense TagPack format. The same pack was submitted upstream as graphsense/graphsense-tagpacks#53.

Every row carries the URI of the primary public source it was taken from. No third-party or licence-restricted attribution sources are included (no OpenSanctions, no Dune Spellbook, no commercial vendor data).

Composition (as of lastmod 2026-08-25)

currency	rows
BTC	532
TRX (Tron)	280
ETH	124
LTC	13

97 distinct designated entities; category sanction for all rows; source https://www.treasury.gov/ofac/downloads/sdn.csv.

Files

• aidecisions_ofac.parquet — columns address, currency, label, source, category (zstd, 30.9 KB)
• aidecisions_ofac.yaml — the original TagPack (header: title, creator, description, lastmod; body: tags)

Provenance and limitations

• Source of truth is the OFAC SDN CSV; addresses are extracted from the ID / remarks fields by openlabels parsers (Tron base58check ↔ hex handled; case policy per chain).
• Designations change: a delisted address stays in an old snapshot. Re-generate with openlabels for a fresh cut.
• A label is an attribution to a designated entity as published by OFAC, not a judgement of any counterparty.

How it was built

pip install "openlabels[tagpack] @ git+https://github.com/ai-decisions/openlabels"
python -m openlabels.tagpack.generate_tagpack --help
