Events — on-chain transactions (preban / ban / unban / destroy). Addresses — unique wallets. The same address may go through multiple events during its lifecycle, so events always outnumber addresses.

How we catch the signal
From Tether's intent to block an address to the actual freeze, hours pass. We detect it at the earliest stage.
01
Early detection
We monitor on-chain in real time. When an address enters Tether's block queue, we capture the signal before the freeze actually executes.
02
Intent verification
We confirm the chain and address, capture the balance at the time of the signal, and deduplicate against known events. Only confirmed signals reach the channel.
03
Push to channel in <10s
REST API, WebSocket, Telegram bot. Payload includes chain, address, estimated window, and a link to the on-chain transaction for independent verification.

FAQ — common questions
Didn't find the answer? Reach out via support, Telegram, or GitHub Issues.
How reliable is the preban signal?
Every preban is a real on-chain event — we don't interpret it, we record it. There are no false positives: either the event is on the chain, or it isn't.
Does preban ever get cancelled?
Yes. Historically about 3–5%. If no block happens within 7 days of the alert, we mark it as «expired».
What's the typical preban → ban window?
Median 4–18 hours. 90th percentile — 48 hours. OFAC cases close fastest (often <1h). Slowest are erroneous blocks that get reversed later.
What about other stablecoins — USDC, DAI?
USDT only for now. USDC and DAI have a fundamentally different centralized-approval architecture, so our early detection doesn't transfer directly. Each issuer needs separate work.
Is the API paid?
No, the public REST API is free at api.cryptoalert.report with an IP-based rate limit (60 req/min). Premium gets a personal key without a rate limit and access to the preban endpoint.
Where does the data live and who has access?
Postgres on our VPS (EU). Premium users' watchlist addresses are encrypted at rest. Enterprise — your on-prem, we don't see addresses at all. Details in the Security whitepaper.
