Binance has announced the full coverage of all assets impacted by the major security incident that occurred on October 29, 2026. In an official statement shared on the X platform, the cryptocurrency exchange confirmed that it has replenished the affected funds using its own corporate resources and the Secure Asset Fund for Users (SAFU). Alongside this recovery milestone, the platform has released a new Proof-of-Reserves (PoR) snapshot, allowing the community to verify the solvency and backing of their digital assets.
Zero-Knowledge Proofs for Enhanced Transparency
To ensure the integrity of the reported figures, Binance integrated zero-knowledge proof (zk-SNARK) technology into its verification system. This cryptographic method enables users to independently confirm that their individual account balances are backed at a 1:1 ratio without compromising the privacy of other customers.
According to the exchange, the process of generating these proofs requires significant computational power, typically taking between 40 to 60 hours depending on the number of tokens included in the audit.
The latest verification phase includes the following key aspects:
- Implementation of Merkle Tree structures to confirm the inclusion of specific account data.
- Coverage of major assets including Bitcoin (BTC), Ethereum (ETH), Tether (USDT), and BNB.
- Expansion of the snapshot scope from an initial 10 tokens to 44 digital assets in the latest update.
Context of the October 2026 Security Incident
The recovery efforts follow a sophisticated breach on October 29, which resulted in unauthorized withdrawals totaling approximately US$6.3 billion. Investigations by the FBI and blockchain intelligence firms initially attributed the attack to the North Korea-linked TraderTraitor group. The attackers reportedly targeted hot wallets across multiple networks, including the XRP Ledger, Solana, and Ethereum.
"Binance will absorb the financial impact of the stolen funds, not our users. We have already set aside more than 100% of the funds required to cover the loss", the exchange stated during the recovery process.
While a portion of the stolen assets—estimated at US$2.85 billion—was frozen on-chain through coordination with industry partners like Tether and Circle, Binance utilized its treasury to bridge the gap for the remaining illiquid or unrecovered tokens.
System Strengthening and Future Outlook
In response to the breach, Binance has undergone a comprehensive infrastructure overhaul. The exchange reported rebuilding affected wallet systems in new environments and decommissioning credentials associated with the compromised entry points. Enhanced security measures now include AI-based behavioral anomaly detection and stricter device controls for its engineering teams.
The successful generation of the latest Proof-of-Reserves and the completion of asset coverage mark a significant step in the exchange's efforts to restore platform stability. Moving forward, Binance plans to continue its periodic attestation program to maintain transparency regarding its custodial holdings.
