Cryptocurrency exchange Binance began a controlled restoration of asset withdrawals on November 1, 2026, three days after a historic $6.3 billion hot wallet exploit, revealing that it has already covered approximately 95% of stolen funds using corporate reserves.
Phased Withdrawal Rollout and Reserve Coverage
Binance initiated its network-by-network rollout on November 1, reopening the Bitcoin network first to perform comprehensive security checks. The exchange subsequently restored service for several major chains, including MATIC (Polygon) for POL, USDT, and USDC, as well as AVAXC for AVAX, USDT, and USDC. These joined previously re-enabled networks such as BTC, ETH (including USDT and USDC), BSC (for BNB, USDT, and USDC), XRP, and Base.
To safeguard user balances, Binance set aside more than $6.34 billion in reserves. While Binance pledged full reimbursement immediately after the breach, the remaining 5% gap comprises less liquid tokens that the exchange is actively purchasing on the open market. Deposits remained fully operational throughout the incident.
Details of the Historic $6.3 Billion Breach
The breach occurred on October 29, 2026, when attackers drained roughly $6.3 billion from Binance hot wallets across multiple blockchains in under four hours, with the bulk of the transfers taking place in a 20-minute window. The incident eclipses the $1.5 billion Bybit breach from 2025 as the largest theft in crypto history. The FBI Cyber Branch publicly attributed the attack to North Korea's TraderTraitor group, as FBI attributed the attack to TraderTraitor while ecosystem security partners froze between $2.7 billion and $3 billion in stolen assets on-chain.
The attack severely impacted derivative markets. Bitcoin dropped over 3% to touch a six-week low near $76,000, while Ethereum and BNB posted sharp declines. According to CoinGlass data, overall leveraged liquidations exceeded $628 million in a single hour, primarily hitting long positions as BTC, ETH, and XRP plunged.
Key Takeaways
- Withdrawals Restored: Binance re-enabled transfers across BTC, ETH, BSC, XRP, Base, Polygon, and AVAXC following security audits on November 1.
- 95% Covered: Binance allocated over $6.34 billion from reserves to reimburse users, with remaining funds being acquired in illiquid token markets.
- FBI Attribution: Authorities linked the October 29 exploit to North Korea's TraderTraitor, with security teams freezing $2.7 billion to $3 billion on-chain.
- Market Impact: Liquidation volume reached $628 million in one hour as Bitcoin fell to $76,000.
Why It Matters
Binance's ability to self-fund a $6.3 billion loss without halting deposits or freezing operational liquidity highlights an unprecedented level of reserve capitalization among centralized exchanges. By systematically opening withdrawals within three days, the exchange has largely mitigated immediate systemic contagion risk across crypto markets. However, the breach underscores severe persistent vulnerabilities in hot wallet architecture, guaranteeing heightened regulatory scrutiny and stricter mandatory security frameworks for centralized platforms moving forward.
