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. Evidence strength: Multiple publishers, 2 publisher group(s) (Decrypt, Cointelegraph). No complete post-detection return window is available yet. ## Claims and open questions - 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. - 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. ## Source evidence - [Binance Drained of $5.5 Billion in Suspected Hack, Tether and Circle Freeze $1.8 Billion]() — Decrypt; published Oct 29, 2026, 21:36; received Oct 29, 2026, 21:39 (UTC). - [Binance hit by $5.8B hack as Tether and Circle freeze billions]() — Cointelegraph; published Oct 29, 2026, 21:24; received Oct 29, 2026, 22:40 (UTC). ## Recent USDT events and market reactions - [Senate Democrat seeks Tether records on payments tied to Nxum]() — Published Oct 23, 2026, 17:42 (UTC) · Multiple publishers (4 publishers) · Regulation · Complete reaction windows unavailable - [Full coin archive]() ## Recent Security events on other coins - [BNB: Binance-linked wallet transfers rattle crypto markets as BNB falls 7%]() - [BTC: Bitcoin falls below $79,000 amid reports of suspected Binance hack]() - [BTC: Bitcoin Core discloses undo file overflow bug and fixes it in new releases]() - [Security]() ## Research for this archive - [Does crypto news move prices or follow them?

How to check the evidence behind a price explanation]() 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. [Methods and limitations]()
