Cryptocurrency exchange Binance has published a new, independently verifiable Proof of Reserves following a major security breach on October 29, 2026. The company says it has replenished approximately 95% of the assets affected by the incident, while continuing to restore withdrawal services and acquire the remaining cryptocurrencies needed to replace stolen holdings.
The announcement represents a significant development in the response to an attack estimated at more than $6.3 billion. Rather than relying solely on statements about customer protection, Binance has now released cryptographic verification for ten major cryptocurrencies, allowing eligible account holders to check whether their balances were included in the exchange’s reported reserves.
On November 2, Binance confirmed that the zero-knowledge proof associated with its October 31 reserve snapshot had been completed. The covered assets include Bitcoin, Ethereum, Tether, BNB, Solana, USD Coin, XRP, USD1, Ripple USD, and Zcash.
According to Binance’s official November 2 recovery announcement, those ten assets are backed by reserves at a minimum ratio of 1:1 within the published verification framework.
The distinction between replenishing assets, verifying reserves, and recovering stolen cryptocurrency is important. Binance’s replacement of affected assets does not mean investigators have retrieved the same funds stolen during the attack.
The developments also have implications beyond cryptocurrency exchanges. Online gambling platforms, crypto casinos, and payment providers that rely on digital asset infrastructure face similar questions about custody, liquidity, operational security, and how customer balances are protected during a financial or technological disruption.
What Binance Confirmed In Its November 2 Recovery Update
Binance’s fifth security recovery update provided three important developments: the completion of its latest cryptographic reserves proof, progress toward replacing affected assets, and a timetable for expanding withdrawal availability.
The exchange said approximately 95% of the affected assets had been replenished using its own financial resources and designated protection funds.
The remaining 5% consists primarily of less-liquid cryptocurrencies outside the ten assets covered by the latest verification.
These tokens can be more difficult to purchase in large quantities without affecting market prices or encountering insufficient available supply.
Binance said it was working with industry partners to acquire the outstanding assets through available market channels.
The company also confirmed that it planned another Proof of Reserves snapshot for November 4, 2026, expanding coverage to additional tokens.
Generating the corresponding zero-knowledge proof is expected to require approximately 40 to 50 hours because of the computational resources involved.
| Recovery Indicator | Reported Status |
|---|---|
| Security incident | October 29, 2026 |
| Estimated stolen assets | More than $6.3 billion |
| Affected assets replenished | Approximately 95% |
| Remaining replenishment | Approximately 5% |
| Latest reserves snapshot | October 31, 2026 |
| Cryptographic proof completed | November 2, 2026 |
| Cryptocurrencies covered | 10 |
| Next planned snapshot | November 4, 2026 |
These figures reflect the company’s announcements available as of November 3. They should not be interpreted as an independent audit of Binance’s entire financial position.
The immediate importance of the announcement is that users holding the ten covered cryptocurrencies now have a way to verify specific reserve claims instead of relying exclusively on the exchange’s assurances.
How The October 29 Binance Hack Affected Customer Assets
The security incident occurred on October 29, when attackers exploited weaknesses involving Binance’s internal infrastructure and wallet-signing operations.
According to blockchain investigation company Bitquery, approximately $6.3 billion moved from 17 Binance hot wallets across nine blockchains during a period of less than four hours.
The investigation identified unauthorized transactions involving major cryptocurrencies and stablecoins, making the incident one of the largest reported digital asset thefts.
The Bitquery investigation of the Binance attack examined blockchain movements recorded between October 29 and November 2, including the transfer of stolen assets and subsequent freezing activity.
The attack also raised questions about how centralized exchanges manage authorization permissions, employee access, wallet infrastructure, and emergency transaction controls.
A hot wallet is a cryptocurrency wallet connected to systems capable of initiating blockchain transactions. Such wallets support everyday exchange operations, including deposits and withdrawals, but require strict safeguards because compromised transaction authority can create substantial financial exposure.
Binance has indicated that the investigation involves more than a straightforward private-key theft.
The complete technical sequence remains subject to investigation, and public reporting should not be treated as a definitive forensic account of every security failure involved.
Following the incident, Binance restricted certain withdrawal services while investigating the breach and reorganizing affected infrastructure.
Those restrictions created a separate operational concern for customers: whether assets shown in account balances could be accessed when needed.
That issue makes the subsequent reserve verification especially significant.
What Binance Proof Of Reserves Actually Demonstrates
Proof of Reserves is a verification process intended to demonstrate that a cryptocurrency custodian holds assets corresponding to customer balances.
For an exchange, a basic reserve claim means that customer liabilities denominated in a particular cryptocurrency are supported by at least an equivalent quantity of that asset.
A 1:1 reserve ratio means that, within the applicable calculation, each unit owed to customers is backed by at least one unit held in the exchange’s reported reserves.
For example, if an exchange owes customers 100,000 units of a cryptocurrency, a 1:1 backing claim requires it to demonstrate at least 100,000 corresponding units in the relevant reserve calculation.
Binance’s latest disclosure uses a combination of Merkle-tree accounting and zero-knowledge cryptography to support its claims.
A Merkle tree organizes account-balance information into a cryptographic structure that allows individual records to be verified against a published commitment without exposing every account entry.
Zero-knowledge proofs add another verification mechanism. They can demonstrate that certain mathematical conditions are satisfied without publicly revealing all the underlying information.
Binance uses a form of zero-knowledge proof known as a zk-SNARK.
The objective is to let customers verify that their account balances are represented in the published reserve calculation while protecting sensitive information about other users.
However, Proof of Reserves has limitations.
It does not automatically demonstrate that an exchange has no undisclosed liabilities, that all its business operations are profitable, or that every security vulnerability has been resolved.
It also does not establish that withdrawals will always remain available under every market condition.
The latest Binance proof applies to a specific snapshot and the assets included in that snapshot. It should not be interpreted as a continuous guarantee covering every cryptocurrency or every future transaction.
Which Cryptocurrencies Are Covered By The New Reserves Verification?
Binance’s November 2 announcement identifies ten cryptocurrencies included in the completed verification.
These assets represent several different segments of the digital asset market, including major blockchain networks, stablecoins, and exchange-related tokens.
| Cryptocurrency | Symbol | Asset Category |
|---|---|---|
| Bitcoin | BTC | Cryptocurrency |
| Ethereum | ETH | Smart-contract network asset |
| Tether | USDT | U.S. dollar-linked stablecoin |
| BNB | BNB | Blockchain ecosystem token |
| Solana | SOL | Smart-contract network asset |
| USD Coin | USDC | U.S. dollar-linked stablecoin |
| XRP | XRP | Digital payment asset |
| World Liberty Financial USD | USD1 | U.S. dollar-linked stablecoin |
| Ripple USD | RLUSD | U.S. dollar-linked stablecoin |
| Zcash | ZEC | Privacy-oriented cryptocurrency |
Binance says the covered customer balances are backed at a minimum ratio of 1:1.
This does not mean every asset held on Binance was included in the November 2 verification.
The remaining affected assets include tokens with lower liquidity, and the company has said acquiring the necessary quantities may require additional time.
The planned November 4 snapshot is intended to expand coverage.
For customers, the important distinction is between an asset that has been included in a completed verification and one that remains outside the latest published proof.
Users should consult the exchange’s official verification materials for the coverage and snapshot applicable to their holdings.
How Binance Replenished 95% Of The Affected Assets
Binance’s recovery strategy relies on replacing stolen cryptocurrency with assets obtained from financial resources controlled by the company.
The exchange has identified three funding sources: its corporate treasury, a portion of the Secure Asset Fund for Users, and part of its futures insurance fund.
The Secure Asset Fund for Users, commonly called SAFU, is a protection reserve Binance established to help address exceptional losses affecting customers.
The futures insurance fund serves a different purpose. It supports the exchange’s derivatives risk-management framework and is designed to absorb certain losses associated with leveraged trading.
Binance has said that the amount remaining in the futures insurance fund continues to satisfy its applicable risk-management requirements.
These distinctions matter because the three funding sources have different operational purposes.
Corporate treasury resources support the company’s general financial obligations. SAFU is intended to provide an additional customer-protection mechanism. Futures insurance funds address specific risks arising from derivatives activity.
Using these resources to replace stolen assets can help restore customer backing, but the longer-term implications depend on how much was deployed and whether the funds are subsequently rebuilt.
In its October 31 asset replenishment update, Binance said it had allocated more than $6.34 billion in company-controlled resources to cover the losses and had increased the replenishment ratio from approximately 80% to 90%.
By November 2, that figure had reached approximately 95%.
The progression demonstrates substantial reported progress over several days, although the remaining assets and operational restrictions still require attention.
Why Replenishing Stolen Cryptocurrency Is Not The Same As Recovering It
The language surrounding major cryptocurrency hacks can create confusion.
When an exchange replenishes stolen assets, it replaces the missing value or token quantities using other resources.
When investigators recover stolen cryptocurrency, they regain control of assets previously transferred without authorization.
These are fundamentally different outcomes.
An exchange might restore its customer reserves even while attackers retain possession of the original stolen cryptocurrency.
Conversely, investigators might freeze stolen assets without immediately returning them to the affected institution.
The October 29 incident illustrates both processes.
Blockchain investigators have traced substantial quantities of stolen assets and documented intervention by stablecoin issuers and other blockchain participants.
Bitquery reported that approximately $2.7 billion had been frozen by November 2 through actions involving Tether, Circle, Arbitrum, and other entities.
A freeze can prevent certain assets from moving, but it does not necessarily establish that they have been recovered, legally seized, or returned to customers.
The remaining stolen funds may continue to be investigated across multiple blockchains and wallets.
For readers evaluating exchange security, it is important to separate three measurements: assets replaced by the company, assets immobilized by third parties, and assets actually recovered through investigative or legal processes.
Treating those figures as interchangeable can substantially misrepresent the financial outcome of an incident.
<WritingBlock id=”62841″ variant=”document”>## Why Binance Is Restoring Withdrawals In Phases
Replacing stolen assets is only one part of recovering from a major exchange security incident.
Binance must also restore operational services while ensuring that the infrastructure used to process withdrawals is secure.
Following the October 29 attack, the exchange restricted withdrawals on affected networks and began a phased restoration process.
Its November 2 announcement indicated that additional networks and assets were expected to become available progressively from November 3.
That schedule represents the company’s stated recovery plan rather than confirmation that every withdrawal service has resumed.
A phased restoration can allow an exchange to test security controls, monitor transaction activity, and reduce operational risks before restoring full functionality.
However, it also means that customers may experience different levels of access depending on the cryptocurrency and blockchain network involved.
For example, the availability of Bitcoin withdrawals does not necessarily establish that every Ethereum-compatible token or smaller blockchain asset can be withdrawn.
The distinction between reserve backing and withdrawal availability is particularly important during a crisis.
A cryptocurrency exchange may demonstrate that certain customer balances are backed while still temporarily restricting transfers for security or operational reasons.
For customers, both measurements matter.
Reserve verification addresses whether the reported assets exist within the applicable accounting framework. Withdrawal availability addresses whether customers can access and transfer those assets when permitted.
According to The Block’s November 2 report on Binance’s recovery, the company was preparing to expand withdrawal access while continuing work on the remaining asset replenishment.
What The Binance Incident Means For Crypto Casinos And Gambling Platforms
Although Binance is a cryptocurrency exchange rather than a sportsbook or online casino, its security incident raises relevant questions for gambling businesses that accept or hold digital assets.
Some cryptocurrency gambling platforms depend on external exchanges, payment processors, blockchain networks, or custody providers to manage deposits, withdrawals, and operational liquidity.
A disruption involving one of those services can create downstream problems even when the gambling platform itself has not been compromised.
For example, a crypto casino that relies on an external liquidity provider may experience delays if that provider restricts withdrawals or temporarily suspends transactions on a particular blockchain.
Similarly, a sportsbook accepting cryptocurrency payments must distinguish between funds that have been credited to a customer account and funds that are actually available within its payment infrastructure.
These are general operational risks, not evidence that the Binance incident directly affected any particular casino or sportsbook.
The case also highlights why operators should understand the custody arrangements used by their payment partners.
A platform may advertise cryptocurrency deposits without clearly explaining whether it holds customer assets directly, uses a third-party custodian, or converts deposits into another currency.
Those differences can become important when a security incident affects liquidity or transaction processing.
From a compliance perspective, the Binance recovery illustrates the value of transparent reserve reporting, documented incident-response procedures, and clear communication about service restrictions.
However, the relevance of Proof of Reserves depends on the business model. A gambling operator that does not custody cryptocurrency customer balances may have different financial reporting obligations from a centralized exchange.
How Customers Can Verify Their Binance Reserves
Binance has published a verification process for customers whose assets are included in its latest Proof of Reserves snapshot.
According to the company’s official documentation, users can access the verification area of their Binance account and locate the relevant reserve record.
The process allows eligible customers to check whether their balances were included in the October 31 snapshot.
Binance also provides an open-source verification tool for users who want to conduct the cryptographic check independently.
The verification process is designed to confirm the inclusion of account balances and the validity of the relevant cryptographic proof.
Customers should understand that the result applies to the selected snapshot date rather than every subsequent change to their holdings.
Binance’s official Proof of Reserves documentation explains how Merkle-tree records, reserve calculations, and zero-knowledge verification are used.
The company also warns users to access verification materials through its official website rather than links received in unsolicited messages.
That precaution is particularly relevant following a widely publicized security incident.
Fraudsters sometimes exploit confusion surrounding exchange disruptions by circulating fake compensation notices, impersonating customer support representatives, or directing users toward fraudulent wallet-connection pages.
Legitimate reserve verification should not require customers to disclose account passwords, recovery phrases, or private wallet keys to an unknown third party.
Why Proof Of Reserves Does Not Eliminate Exchange Risk
Binance’s new reserve verification provides additional information about the backing of selected customer assets, but it does not eliminate the risks associated with centralized cryptocurrency custody.
A cryptocurrency exchange faces several different categories of risk.
Cybersecurity failures can result in unauthorized transfers. Liquidity problems can interfere with withdrawal processing. Operational disruptions can affect access to trading or account services.
Financial risks may also arise from obligations that are not fully represented in a particular reserve snapshot.
Proof of Reserves addresses a specific part of this broader risk environment.
It can provide cryptographic evidence about reported asset backing, but it is not necessarily equivalent to a comprehensive financial statement audit or an independent assessment of cybersecurity controls.
Even a correctly generated proof does not guarantee that an exchange cannot experience another security incident.
Binance itself acknowledges some of these limitations in its educational explanation of Proof of Reserves, including the point-in-time nature of reserve verification and the difficulty of independently evaluating all off-chain liabilities.
The October 29 incident demonstrates why reserve transparency and security controls must be considered separately.
Customers benefit from knowing whether reported balances are backed, but they also depend on effective access controls, secure wallet-signing procedures, transaction monitoring, and reliable withdrawal infrastructure.
For gambling platforms using cryptocurrency services, these considerations extend to the financial and technical resilience of third-party payment partners.
What Happens Next For Binance’s Recovery?
The next major scheduled development is Binance’s planned November 4, 2026 Proof of Reserves snapshot.
The company intends to expand the number of cryptocurrencies covered and generate a new zero-knowledge proof over the following 40 to 50 hours.
Further updates are also expected concerning the remaining 5% of affected assets and the restoration of withdrawals across additional networks.
The outstanding asset replenishment may take longer because some affected tokens have relatively limited market liquidity.
Meanwhile, blockchain investigators continue tracking stolen cryptocurrency, including assets that have been frozen and funds that remain under attacker control.
These parallel processes will determine how much of the original theft is ultimately recovered, how quickly Binance completes its replacement commitments, and whether additional operational changes become necessary.
For the broader digital asset industry, the incident raises an important question about the standards exchanges should meet after a major security breach.
Publishing a verifiable reserve snapshot is a measurable step toward transparency. Yet the strength of the overall recovery will depend on the completion of asset replenishment, reliable withdrawal access, and credible evidence that the security weaknesses involved in the attack have been addressed.
The same distinction applies to cryptocurrency payment providers serving online gambling businesses: financial backing, operational availability, and cybersecurity resilience are separate requirements, and confidence in one does not automatically establish the others.
