In an evolving digital asset landscape, security remains the cornerstone of trust between users and cryptocurrency exchanges. As one of the leading platforms in the industry, OKX continues to strengthen its security infrastructure, transparency practices, and user protection mechanisms. This June 2025 security report provides a comprehensive overview of OKX’s commitment to safeguarding user assets, enhancing transaction safety, and maintaining full reserve integrity.
🔐 Fund Security: Proven Reserves and Full Transparency
Transparency is not just a policy at OKX—it's a standard practice backed by advanced cryptographic technology. The platform has now released its 8th Proof of Reserves (PoR) report, reinforcing its commitment to full asset backing.
Proof of Reserves (PoR) – June 30, 2025 Snapshot
As of June 30, 2025, OKX’s user asset holdings are as follows:
- BTC: 136,769 BTC
- ETH: 1,048,454 ETH
- USDT: 4,903,812,593 USDT
To ensure accuracy and privacy-preserving verification, OKX utilizes the cutting-edge zk-STARK cryptographic proof system. This method enables trustless validation of reserves without exposing sensitive wallet data. The PoR coverage now spans 22 major cryptocurrencies, offering broader transparency across the platform’s most-traded assets.

On-Chain Wallet Holdings & Reserve Ratio
OKX publishes real-time wallet balances for key assets to validate its reserve status:
- BTC: 140,647 BTC
- ETH: 1,081,278 ETH
- USDT: 5,056,389,887 USDT
These figures confirm that OKX maintains a reserve ratio of 103% for BTC, ETH, and USDT—ensuring that user funds are fully backed with a comfortable buffer. A reserve ratio above 100% demonstrates financial resilience and reinforces confidence in the platform’s ability to meet all withdrawal demands at any time.
This level of transparency sets a new benchmark in the centralized exchange space, where users increasingly demand verifiable proof over blind trust.
The Omni Fund: A $1 Billion Safety Net
Security doesn’t stop at reserves. The OKX Omni Fund has now surpassed $1 billion in total value, serving as a strategic safeguard against unforeseen market events or systemic risks.
This fund works in tandem with OKX’s industry-leading asset security risk control system, designed to detect anomalies, mitigate threats, and protect both new and long-term users. Whether facing extreme volatility or external attacks, the Omni Fund ensures that user assets remain secure and recoverable.
🛡️ Transaction Security: Advanced Risk Controls in Action
User protection extends beyond storage—it’s embedded in every transaction. In June 2025, OKX’s risk management systems demonstrated their effectiveness through measurable outcomes.
Anti-Phishing & Withdrawal Protection
Cyber threats like phishing attempts remain a top concern for crypto users. In June alone:
- 529 users were protected from fraudulent withdrawals
- 564 malicious withdrawal attempts were successfully blocked
- Approximately 154,200 USDT in assets were preserved
These interventions were powered by real-time behavioral analysis and machine learning models that identify suspicious patterns before damage occurs.
Risk Provision Fund: Preventing Liquidation Losses
Market volatility can lead to forced liquidations, especially in derivatives trading. To shield users from cascading losses, OKX maintains a robust Risk Provision Fund, which stood at $1.049 billion in June.
During the month, this fund was triggered approximately 375,200 times, helping traders avoid complete margin wipeouts during sharp price swings. This proactive mechanism stabilizes the trading environment and promotes fairer outcomes for all participants.
🔑 API Security: Smarter Access Management
APIs are essential for advanced trading strategies but also represent potential vulnerabilities if mismanaged.
In June 2025, OKX implemented strict hygiene protocols:
- 965 API keys were created via Fast API integration
- 903 API keys were bound to third-party applications with enhanced permission controls
- A total of 8,348 inactive API keys (unused for 14+ days and unbound to IP addresses) were automatically deleted
This proactive cleanup reduces the attack surface and ensures only authorized, active connections have access to user accounts—significantly lowering the risk of unauthorized trades or fund movements.
🧠 User Protection Initiatives: Empowering Safer Trading
OKX recognizes that many risks stem not from technology but from human behavior. That’s why behavioral safeguards play a crucial role in platform security.
The "Beginner Protection Program" – Cooling-Off Periods for Contracts
Impulsive decisions in futures trading can lead to significant losses. To combat this, OKX introduced the Contract Cooling-Off Period, part of its broader Beginner Protection Program.
In June:
- 9,682 users activated the cooling-off feature
- This pause allows traders to reconsider high-risk positions before executing trades
By encouraging mindful decision-making, OKX helps reduce emotional trading and supports long-term user success.

Handling Wrong Asset Deposits
Mistaken deposits—sending unsupported tokens to exchange wallets—are common and often irreversible elsewhere. OKX takes a user-first approach:
- 131 manual interventions resolved错充 issues, recovering assets valued at $255,100
- For unsupported tokens, the Auto Deposit/Withdrawal System processed 266 cases, returning $643,900 worth of funds
These efforts reflect OKX’s dedication to minimizing user error consequences through both automated systems and responsive support teams.
Frequently Asked Questions (FAQ)
Q: What is Proof of Reserves (PoR), and why does it matter?
A: Proof of Reserves is a cryptographic audit that verifies an exchange holds sufficient assets to cover all user balances. It ensures transparency and prevents fractional reserve practices. OKX uses zk-STARK proofs for privacy-safe verification across 22+ coins.
Q: How does OKX protect me from phishing attacks?
A: OKX employs real-time monitoring systems that analyze login behavior, device fingerprints, and withdrawal patterns. Suspicious activities trigger alerts or blocks, protecting over 500 users monthly from fund theft.
Q: Is my API key safe on OKX?
A: Yes. OKX enforces strict API key lifecycle management—automatically removing inactive or unsecured keys. You can also bind keys to specific IP addresses and limit permissions for added safety.
Q: What happens if I send a token not supported by OKX?
A: While automatic recovery is limited for unsupported tokens, OKX’s support team reviews each case. If technically feasible, they assist in retrieving the funds—recovering over $640K in June alone.
Q: How does the Risk Provision Fund benefit me?
A: If your position faces liquidation during extreme volatility, the fund may cover part of the loss, preventing negative balances and reducing cross-liability risks in the insurance pool.
Q: Can I verify OKX’s reserves myself?
A: Absolutely. Using the published Merkle tree data and wallet addresses, independent auditors or technically skilled users can validate that OKX’s on-chain holdings exceed user liabilities.
