Key Summary
Binance published its October 31 Proof of Reserves report revealing full collateralization above 100% for top traded assets despite a $6.3B cross-chain exploit.
Key Bullets
- Binance published its Proof of Reserves report on October 31 confirming XRP coverage at 100.99% and RLUSD at 100.83%.
- Hackers withdrew approximately $6.30B across ten blockchains before Binance suspended network deposits and withdrawals.
- Binance allocated $6.34B from the SAFU fund and corporate retained earnings to cover the missing user balances.
- On-chain partners froze $3.00B of the stolen funds while OTC desks absorbed the remaining low-liquidity token buybacks.
Binance Reports Full Asset Backing
Binance published its latest Proof of Reserves report as of October 31, 2026, confirming client funds remain fully backed above 100% across major traded assets. According to audit disclosures released by the exchange, coverage for XRP reached 100.99% alongside 100.83% for the Ripple USD stablecoin. The verification data relies on cryptographic Merkle trees and zero-knowledge proofs to allow client-side balance auditing.
The release follows an unprecedented security breach on October 29 that drained approximately $6.30B from exchange wallets across ten distinct blockchains. Hackers targeted cold and hot storage configurations, forcing an immediate suspension of all network deposits and withdrawals. Protocol engineers scrambled to halt further bleeding.
Internal Capital Plugs Billion Dollar Hole
Binance allocated $6.34B of corporate capital from retained earnings, the Secure Asset Fund for Users, and the futures insurance fund to restore 1:1 backing. Protocol partners including Tether, Circle, and Ripple blacklisted and froze $3.00B of the stolen assets directly on-chain within hours of the attack. Liquidators deployed over-the-counter desks to acquire remaining low-liquidity tokens without triggering spot market slippage.
The platform demonstrated immediate balance sheet elasticity under severe operational stress. Solvency metrics recovered faster than historical exchange hacks. Traders accepted the rapid capital injection as proof of corporate liquidity.
Exchanges Face New Solvency Standards
Public on-chain transaction records confirm the audit logs verify total collateral for the ten most traded assets, including BTC, ETH, USDT, BNB, and SOL. Market participants evaluated the incident not by the breach itself, but by the speed of the treasury response and self-funded remediation. Capital remained secure inside user accounts.
Auditors verified that user withdrawal queues cleared normally once network suspensions lifted across all supported blockchain networks. Industry standards for exchange risk management shifted overnight. Cash reserves covered every single liability.
