Security Audit Reports Collection for OKX Wallet

·

In the fast-evolving world of blockchain and decentralized finance (DeFi), security is paramount. As digital asset adoption grows, so do the risks associated with storing and managing private keys, executing smart contracts, and interacting with decentralized applications (dApps). This is why comprehensive third-party security audits are essential for any reputable crypto wallet provider.

OKX Wallet has consistently prioritized user safety by undergoing rigorous security evaluations from globally recognized firms such as CertiK and SlowMist. These audits cover critical components including front-end interfaces, mobile applications (iOS and Android), Software Development Kits (SDKs), Multi-Party Computation (MPC) wallets, smart contracts, and key management modules.

This article compiles and organizes the verified security audit reports of OKX Wallet, offering transparency into its robust security framework and continuous commitment to protecting user assets.

CertiK Security Audits

All vulnerabilities have been resolved, ensuring a secure experience for users engaging with OKX Wallet’s core functionalities.

Threshold-lib Module

The Threshold-lib module — a foundational component enabling secure threshold cryptography operations — also underwent a full audit by CertiK. The review confirmed that the implementation meets high standards of cryptographic integrity and resistance to known attack vectors.

Core Smart Contracts Audit

CertiK evaluated several key smart contracts powering OKX Wallet’s DeFi and NFT capabilities:

✅ Audit Outcome: Low-risk rating with all identified issues resolved.

These contracts form the backbone of OKX Wallet’s interoperability features, allowing users to access diverse DeFi protocols securely.

Solana Marketplace Audit

OKX’s marketplace built on the Solana network was also audited by CertiK. Given Solana’s high-speed, low-cost environment, securing smart contracts on this chain is crucial due to its unique execution model.

🔍 Result: The audit concluded with a low-risk assessment, and all findings were remediated prior to deployment.

This ensures safe interactions when users trade NFTs or engage with Solana-based dApps through OKX Wallet.

SlowMist Security Audits

SlowMist, another globally trusted name in blockchain security, has performed extensive testing on multiple OKX Wallet components using both static and dynamic analysis techniques.

Android & iOS MPC Wallets

OKX’s Multi-Party Computation (MPC) wallets for both Android and iOS platforms have passed SlowMist’s rigorous security review.

During the audit process:

All findings were verified and fixed. MPC technology eliminates single points of failure by distributing key shards across multiple parties, significantly enhancing resistance to theft or loss.

✅ Final Verdict: Low-risk outcome with no critical or high-severity vulnerabilities.

This makes OKX’s MPC solution one of the most secure non-custodial options available today.

Ord Module

The Ord module, which supports Bitcoin ordinals and inscriptions within OKX Wallet, was also audited by SlowMist.

Audit findings included:

All issues were resolved, ensuring safe handling of ordinal data without compromising wallet integrity.

Account Abstraction (AA) Account

OKX Wallet’s implementation of Account Abstraction (ERC-4337) was reviewed to ensure secure transaction initiation, gas sponsorship, and session key management.

🔍 Outcome: Low-risk rating with all issues resolved.

This paves the way for smoother user experiences — such as social recovery and paymasters — while maintaining strong security boundaries.

Private Key Module Audit – Critical Security Assurance

One of the most sensitive aspects of any crypto wallet is private key management. OKX Wallet’s private key module has undergone independent third-party verification by SlowMist, confirming two fundamental principles:

🔐 Private keys and seed phrases are stored exclusively on the user’s device.
🛑 Private keys and seed phrases are never uploaded to any external server.

This design ensures full user control over their assets — a cornerstone of non-custodial wallet architecture.
