Blacklists freeze your tokens.
Sanctions lists freeze you.
On-chain blacklists (Tether, Circle) freeze specific addresses. Government sanctions lists designate entities — and every address they touch becomes a compliance liability for anyone in the transaction chain.
Regulatory liability
Transacting with a sanctioned entity — even unknowingly — can trigger OFAC enforcement actions, fines up to $20M per violation, and criminal prosecution under IEEPA.
Counterparty contamination
Your wallet is clean. But the address you received $50K from last month just appeared on the NBCTF terrorist financing list. Now your address is in the same investigation.
Multi-jurisdictional risk
OFAC is US law, but exchanges worldwide screen against it. NBCTF covers Israeli counter-terror. EU MiCA mandates real-time sanctions checks. One missed match, multiple jurisdictions.

Three authoritative sources. One unified screen.
We pull from the same databases that banks, exchanges, and compliance teams use — then cross-reference every address in your wallet's transaction history.
OFAC SDN
US Treasury — Office of Foreign Assets Control
The primary US sanctions list. Covers Lazarus Group (DPRK), Iranian IRGC, Russian oligarchs, and hundreds of designated crypto addresses.
NBCTF
Israel National Bureau for Counter Terror Financing
Seizure orders targeting cryptocurrency addresses linked to Hamas, Hezbollah, and other designated terrorist organizations. 42+ TRON addresses in the latest order alone.
OpenSanctions
Global sanctions aggregator (EU, UK, UN + 30 programs)
Aggregates sanctions data from the European Union, UK HM Treasury, UN Security Council, and 30+ national programs into a single searchable database.
How sanctions screening works
From wallet to alert in under a minute. Continuous re-screening every 6 hours.
Add your wallet
Paste any TRON or Ethereum address. ChainArmor pulls the full transaction history and builds your counterparty graph.
Automatic screening
Every address — yours and every counterparty — is screened against OFAC SDN, NBCTF, and OpenSanctions. Every 6 hours, the lists are re-synced and your wallets are re-screened.
Instant alerts
The moment a match is found — whether your own address or a counterparty — you get notified via email, Telegram, or webhook. Before it becomes a problem.
Investigate & act
Drill into the match: which sanctions list, which entity, which programs. See the relationship graph showing how your wallet connects to the flagged address.
Not just a list check.
Compliance intelligence.
Every sanctions match comes with context — entity names, programs, risk scoring, relationship mapping, and audit-ready reports.
Real-time risk scoring
Sanctions exposure integrates directly into your wallet risk score. An 80-point weight for counterparty matches, 100 for direct hits — the same formula used for on-chain blacklists.
Relationship graphPro+
Visualize exactly how your wallet connects to sanctioned entities through counterparties. See the path, the volume, and the source — all in one interactive graph.
PDF compliance reports
Every Verify report now includes a dedicated Sanctions Screening section with entity names, programs, and source attribution. Audit-ready.
6-hour sync cycle
OFAC, NBCTF, and OpenSanctions data is fetched and re-screened every 6 hours. When a new designation drops, your wallets are checked within the next cycle.
Counterparty drill-down
Click any flagged counterparty to see which list they appear on, the sanctioned entity name, the programs (SDGT, CYBER2, IFSR), and a direct link to the block explorer.
Multi-jurisdictional
US (OFAC), Israel (NBCTF), EU, UK, UN — screened in parallel. One address can appear on multiple lists from different jurisdictions.
See the connection.
Not just the flag.
The sanctions relationship graph shows exactly how your wallet connects to designated entities — through which counterparties, at what volume, and from which sanctions program. One glance tells you whether to worry.

Blacklists + Sanctions = Complete coverage
ChainArmor is the only platform that monitors both on-chain freeze events and off-chain government sanctions in a single risk score.
| On-chain Blacklist | Sanctions List | |
|---|---|---|
| Source | Token issuers (Tether, Circle) | Governments (OFAC, NBCTF, EU, UK, UN) |
| Effect | Funds frozen on-chain | Entity designated — regulatory liability |
| Detection | On-chain event monitoring | Off-chain database screening |
| Timing | After freeze occurs | Before freeze — or even if never frozen |
| Risk | Loss of access to specific tokens | Fines, prosecution, exchange delistings |
Both integrated into one risk score. Both triggering the same alert channels.
