In the rapidly evolving world of blockchain and Web3, security remains a top priority for users and developers alike. As decentralized applications (dApps), digital wallets, and smart contracts become increasingly integral to everyday financial interactions, ensuring the integrity and safety of these systems is non-negotiable. This article compiles comprehensive security audit reports for OKX Wallet, one of the leading Web3 wallet platforms, highlighting its rigorous testing across multiple components by globally recognized cybersecurity firms — CertiK and SlowMist.
These audits cover critical aspects such as front-end interfaces, mobile applications (iOS/Android), Software Development Kits (SDKs), Multi-Party Computation (MPC) modules, private key management, NFT marketplaces, and core smart contracts. Each assessment confirms a low-risk profile with all identified issues fully resolved, reinforcing OKX Wallet’s commitment to user safety and platform reliability.
CertiK Security Audits
CertiK, a world-renowned blockchain security firm, has conducted multiple in-depth audits on various components of OKX Wallet. These assessments focus on code quality, vulnerability detection, and architectural resilience across both client-side and backend systems.
Mobile App & Frontend Components
The iOS and Android mobile applications, along with the frontend interface of OKX Wallet, have successfully passed CertiK's security audit. The evaluation included:
- Source code responsible for wallet creation and import functions
- Password management mechanisms
- Cloud-based data backup processes
- React-based UI components for wallet functionality
- JavaScript controllers interfacing with authentication key managers
During this audit, five security findings were identified:
- Three low-risk issues – flagged for informational purposes
- Two undetermined-risk items – further analyzed and addressed
All findings have since been resolved, ensuring robust protection for end users engaging with the mobile and web interfaces.

Wallet SDK Modules
CertiK also audited several core modules within the OKX Wallet SDK, including:
- Bitcoin SDK
- okwallet-core
- Associated source code repositories
These modules are essential for enabling multi-chain support and cryptographic operations. The audit confirmed secure implementation practices and proper handling of sensitive data flows.
Threshold-lib Library
The Threshold-lib library — a foundational component used in cryptographic threshold signing — underwent independent review by CertiK. This library plays a crucial role in enhancing wallet security by distributing private key shares using advanced MPC protocols. The audit validated its resistance to common attack vectors and confirmed its secure design principles.
Core Smart Contracts
CertiK performed an extensive audit on OKX Wallet’s primary smart contracts, which power key DeFi and NFT functionalities. The following contracts were evaluated:
- DexRouter: Enables cross-DEX asset trading by routing transactions across different decentralized exchanges.
- OkxNFTMarketAggregator: Aggregates listings from multiple NFT marketplaces, allowing seamless buying and selling of digital collectibles.
- Entrance: Acts as a secure gateway that executes authorized instructions from registered adapters.
- UniswapV2AdapterMain: Facilitates staking of Uniswap V2 liquidity provider tokens via integration with yield farming protocols like MasterChef.
The overall audit outcome was classified as low risk, with all identified issues remediated prior to deployment.

Solana Marketplace Audit
OKX’s Solana-based NFT marketplace also underwent a full security assessment by CertiK. Given the high transaction volume and value associated with Solana NFTs, securing this ecosystem is paramount. The audit concluded with a low-risk rating, and all potential vulnerabilities were patched before public release.
SlowMist Security Audits
SlowMist, another leading blockchain security company known for its meticulous penetration testing and threat modeling, has completed multiple audits on OKX Wallet components.
MPC Implementation on Android
The Multi-Party Computation (MPC) module powering OKX Wallet’s Android app was rigorously tested by SlowMist. MPC technology eliminates single points of failure by splitting private key generation and signing processes across multiple parties.
Audit results:
- 9 recommendations provided for optimization
- 1 low-severity finding identified and resolved
- Final assessment: Low risk
All findings were confirmed and fixed, ensuring secure key management without exposing sensitive credentials.
"Security isn’t a feature — it’s the foundation." This principle drives OKX Wallet’s continuous collaboration with third-party auditors like SlowMist to maintain the highest standards.
Ordinal Repository Audit
The Ord repository — related to Bitcoin Ordinals and inscriptions — was also reviewed by SlowMist. The scope included codebase analysis and revision tracking. Findings included:
- 7 low-risk vulnerabilities
- 3 improvement suggestions
All issues were addressed promptly, maintaining compatibility and safety for users interacting with Bitcoin-native digital assets.
Account Abstraction Module
OKX Wallet’s implementation of account abstraction (AA) passed SlowMist’s security audit with a low-risk outcome. Account abstraction enhances user experience by enabling programmable wallets with features like gasless transactions, session keys, and social recovery — all while preserving security.
The audit verified secure contract logic, proper access controls, and resistance to replay attacks and unauthorized execution.
Private Key Module Audit
One of the most critical components of any crypto wallet is private key management. SlowMist audited OKX Wallet’s private key module with the following conclusions:
- ✅ Private keys and seed phrases are stored exclusively on the user’s device
- ❌ Never uploaded or transmitted to external servers
This ensures full user control over their assets at all times. The audit report confirms that no backdoors, data leaks, or insecure storage practices were detected.

Frequently Asked Questions (FAQ)
Q: What is the purpose of a security audit for a crypto wallet?
A: Security audits identify vulnerabilities in code and architecture before malicious actors can exploit them. They provide independent validation that a wallet safely handles private keys, transactions, and user data.
Q: Are OKX Wallet’s private keys ever stored on servers?
A: No. Private keys and recovery phrases are generated and stored solely on the user’s personal device. They are never sent to or stored on any external server, ensuring complete user custody.
Q: How often are OKX Wallet components audited?
A: OKX conducts regular audits with top-tier firms like CertiK and SlowMist — especially before major updates or launches. Continuous monitoring and patching ensure long-term security.
Q: What is MPC, and why does it matter?
A: Multi-Party Computation (MPC) splits cryptographic operations across multiple parties so no single entity ever holds the full private key. It enhances security by eliminating single points of failure.
Q: Can I access the full audit reports?
A: Yes. Detailed audit reports from CertiK and SlowMist are available through official channels and referenced links in this article.
Q: Does OKX Wallet support multiple blockchains securely?
A: Absolutely. OKX Wallet supports over 100 networks with audited cross-chain infrastructure, including secure bridges, DEX aggregators, and multichain NFT markets.
