The largest crypto exchange in the world is dealing with a big security incident. Teams are working around the clock. On October 29, 2026, unusual fund outflows hit Binance hot wallets. Billions of dollars moved out within minutes. Blockchain watchers spotted the strange transfers on Thursday evening. The sudden moves triggered instant alerts across the crypto space. Binance confirmed that its security teams are looking into the event.
The attack took place across ten computer networks. Large sums of tokens left Binance wallets. Big funds moved off Ethereum and Tron. Funds also left Arbitrum and Avalanche. Outflows touched Solana and the XRP Ledger too. Security trackers estimate that attackers moved between five and six billion dollars in tokens. The thief used smart computer rules on Ethereum. These rules drained the funds fast.
Crypto firms moved fast to stop the thief. Stablecoin teams can freeze stolen tokens. They block specific digital addresses. Tether stepped in right away. Tether froze nearly 1.57 billion dollars in USDT. Circle took quick action too. Circle froze eight hundred million dollars in USDC. Ripple froze two hundred million dollars in RLUSD tokens. In total, crypto issuers froze more than 2.6 billion dollars.
Other Web3 groups helped freeze funds too. The Arbitrum council acted fast. They stepped in right away. They froze over eight thousand Ether and seventy-four million ARB tokens. That freeze saved over thirty million dollars. Crypto firm World Liberty Financial also helped freeze twenty nine million dollars with custodian BitGo.
The thief tried to swap stolen stablecoins for other coins. The thief wanted to move fast before freezes took hold. On Ethereum, the attacker swapped tokens on Uniswap. The thief also used lending app Aave to borrow Ether against stolen Tether coins. To stop the attacker, Aave paused its markets on Thursday night. The protocol froze new deposits. It stopped new loans across all networks.
Binance leaders reassured customers that user money remains safe. Co-founder Changpeng Zhao posted a note on social media. He said the event looked like a hack. But he thanked stablecoin firms for their quick help. Co-founder Yi He stated that all customer funds are safe. She explained that Binance keeps user assets backed one-to-one. Active trading continues on the main app. But withdrawals were paused on several chains. This was done for safety checks.

Users will not lose their savings. Their deposits remain safe. The exchange will cover every cent.
