Binance investigates multibillion-dollar wallet breach; Tether and Circle freeze stablecoins

Binance said it is investigating a potential security issue without confirming impact to user funds, after an on-chain tally by Decrypt put outflows linked to its wallets at least $5.57 billion across three blockchains. Tether froze 975.1 million USDT, and Circle froze 823 million USDC, about $1.8 billion combined, per Decrypt; Cointelegraph reported freezes above $2.36 billion.

What sources claim

Binance posted on X that it is aware of reports of a potential security issue and is actively investigating, and that it has not confirmed any impact to user funds, Decrypt reported.
Decrypt's on-chain tally counted $3.51 billion on Ethereum, $1.44 billion in 18,270 Bitcoin and $630 million on Tron, and reported Tether froze 975.1 million USDT while Circle froze 823 million USDC in the main receiving address, about $1.8 billion in total.
Cointelegraph reported that Binance is investigating a multibillion-dollar breach involving its Ethereum wallets, with Tether and Circle freezing more than $2.36 billion in stablecoins.

Still unresolved

Whether Binance will confirm an actual hack and quantify any loss, versus its statement that no impact to user funds has been confirmed, would be established by an official Binance statement or incident report.
The gap between the roughly $1.8 billion in stablecoin freezes tallied by Decrypt and Cointelegraph's figure of more than $2.36 billion would be clarified by issuer statements from Tether and Circle or on-chain data on the frozen addresses.

Evidence levels describe source coverage, not the probability that a report is true. Price moves and their timing cannot establish a cause; minute samples show an observed interval and alert thresholds are heuristics. Explanations are model-assisted, with citations and figures checked. Source titles stay in their original language; full articles are not republished.
