Tether freezes $971 mln in USDT as Binance stays silent on suspected hack

The freeze follows $2.77bn in outflows from Binance wallets across five blockchains, and the exchange has issued no update.

Tether has frozen $971m of its USDT stablecoin in response to a suspected hack at Binance, and the exchange has still said nothing. That silence is now the weak point in the story, because the freeze is a far firmer signal than anything that came before it.

The story began with on-chain data showing $2.77bn leaving Binance wallets across five blockchains on Thursday. Those figures showed money moving, not why. An internal transfer would look the same. A freeze does not. Tether acts only on specific addresses it has reason to flag, so a freeze of nearly $1bn narrows the likely explanations toward a genuine security incident and away from housekeeping.

There is precedent for Tether acting in this way. On October 9 it froze USDT tied to suspected thefts from Ledger wallets of about $90m, according to CryptoSlate, which said the blockchain security firm MistTrack observed the freeze.

The cost of Binance's continued silence is mounting. Every hour without a statement leaves rumour to stand in for confirmed fact, and that damages sentiment toward centralised exchanges and crypto risk appetite more broadly. A hack of this size is bad enough. An exchange that cannot say whether it has been hacked is worse for confidence, and the longer it waits the more the freeze, not Binance, will set the account of what happened.
