+ $83.8M Tether housekeeping — destroyBlackFunds on the USDT contract / null address (users mis-sent USDT there; Tether periodically cleans up). Not included in the main figures above — these are not blacklist actions.
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.

USDT blocks arrive suddenly — and afterwards $1.2B has already burned irreversibly.

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.
