Comparison
Best USDT blacklist checker: 6 tools, compared
We built FreezeRadar, so treat that as a disclosure, not a secret. To keep this useful anyway, every tool below is measured against the same six criteria, defined before any tool is scored, using only facts published on each tool's own site.
Freeze event depth
Whether it tracks only current blacklist status, or freeze, unfreeze, and burn events over time.
Self-serve access
Can you check one wallet right now, for free, without a sales call?
Risk scoring depth
A single flag, or a weighted score built from multiple independent signals?
Pricing transparency
Is pricing published, or does it require contacting sales?
Standout feature
What this specific tool does better than any of the others on this list.

Common questions
What is the best free USDT blacklist checker?
For a self-serve, free check right now, FreezeRadar and usdtbanlist both offer free wallet checks with no sales process. FreezeRadar covers more chains and assets; usdtbanlist has a pre-freeze early warning feature FreezeRadar doesn't.
Which tool tracks unfreeze and burn events, not just current blacklist status?
FreezeRadar, usdtbanlist, and BlockSec all track freeze, unfreeze, and burn events. Bitrace and Scorechain do not publish this as a dedicated feature.
Is Chainalysis overkill for checking one wallet?
For most individuals and small businesses, yes — Chainalysis has no public self-serve tier and targets large institutional buyers. A free, self-serve tool like FreezeRadar or usdtbanlist answers a single-wallet question faster and at no cost.
