Security Audit Reports Collection

·

In the fast-evolving world of blockchain and decentralized finance (DeFi), trust and security are non-negotiable. As digital assets grow in value and adoption, ensuring that wallet infrastructure, smart contracts, and cryptographic modules meet the highest security standards is critical. This article presents a comprehensive overview of independent security audit reports conducted on key components of OKX Wallet, highlighting the platform’s commitment to transparency, resilience, and user protection.

The audits were carried out by globally recognized cybersecurity firms—CertiK and SlowMist—both renowned for their rigorous testing methodologies and deep expertise in blockchain security. These assessments cover frontend systems, mobile applications (iOS/Android), software development kits (SDKs), smart contracts, and core cryptographic modules.

CertiK Security Audits

CertiK is one of the most trusted names in blockchain security, known for its advanced formal verification techniques and real-time on-chain monitoring. OKX Wallet has undergone multiple CertiK audits across various components.

Mobile App & SDK Components

The iOS and Android mobile applications, along with critical SDK modules, have successfully passed security evaluations by CertiK. The audit scope included:

During this assessment, CertiK identified five security issues, all of which were classified as low-risk or informational. Two additional findings were categorized under indeterminate risk levels. Importantly, all identified issues have been fully resolved prior to deployment.

Threshold Cryptography Library

The Threshold Cryptography (Threshold) library used in OKX Wallet was also audited by CertiK. This technology plays a crucial role in enhancing private key protection through distributed signing protocols, reducing single points of failure.

The audit confirmed the robustness of the implementation, with no critical vulnerabilities detected. The results validate OKX Wallet's use of advanced cryptographic techniques to secure user funds without compromising usability.

Smart Contract Audits

Several core smart contracts powering OKX Wallet’s DeFi and NFT functionalities were reviewed:

The overall audit outcome was rated low-risk, with all findings addressed and remediated. These contracts now operate with enhanced security guarantees, providing users confidence when engaging in yield farming, swaps, or NFT transactions.

Solana Market Audit

OKX’s Solana-based marketplace also underwent a thorough review by CertiK. Given Solana’s high throughput and growing ecosystem, securing its integration was essential. The audit concluded with a low-risk rating, confirming that all potential attack vectors were either mitigated or eliminated.

SlowMist Security Evaluations

SlowMist is another leading blockchain security firm, specializing in threat intelligence, penetration testing, and forensic investigations. Their audits provide an additional layer of validation for OKX Wallet’s infrastructure.

OKX MPC Wallet (Android)

The Android version of the Multi-Party Computation (MPC) Wallet was audited by SlowMist. MPC technology allows private keys to be split across multiple parties, eliminating the need to store full keys on any single device.

Findings included:

All issues were verified and fixed before public release. The final assessment concluded with a low-risk rating, affirming the wallet’s resistance to common attack patterns like phishing, malware interception, and unauthorized access.

Ordinals (Ord) Module

The Ordinals (Ord) module, which supports Bitcoin NFTs and inscriptions, was also evaluated. SlowMist identified:

These findings primarily related to input validation and error handling—none posed a direct threat to fund safety. All have been resolved, ensuring safe interaction with Bitcoin’s emerging digital collectibles ecosystem.

Account Abstraction (AA) Implementation

OKX Wallet’s implementation of Account Abstraction (AA) passed SlowMist’s security audit. AA enables smarter, more flexible account management by allowing programmable transaction logic—such as gasless transactions or multi-sig approvals—without relying on traditional EOAs (Externally Owned Accounts).

The audit confirmed that the AA module maintains strong security boundaries, with no high-risk flaws detected. This paves the way for more user-friendly yet secure interactions within the Web3 landscape.

Private Key Module Audit

One of the most critical aspects of any crypto wallet is how it handles private keys. OKX Wallet has made it clear:

Private keys and seed phrases are stored exclusively on the user’s device.
They are never uploaded to external servers or cloud storage.

This principle was validated through a third-party audit by SlowMist. The investigation confirmed that:

This ensures that users retain full control over their assets at all times—a cornerstone of true decentralization.

Frequently Asked Questions (FAQ)

Q: What is the purpose of a blockchain security audit?
A: A security audit identifies potential vulnerabilities in code, architecture, or logic that could be exploited by attackers. It helps ensure that systems handling digital assets are resilient against hacks and fraud.

Q: Why are multiple audits important?
A: Different firms use different methodologies and tools. Conducting audits with both CertiK and SlowMist provides layered assurance and reduces blind spots in security coverage.

Q: Are these audits ongoing or one-time events?
A: Security is continuous. While these reports reflect specific audit cycles, OKX conducts regular internal reviews and periodic third-party assessments to maintain high standards.

Q: Can I view the full audit reports?
A: Yes, detailed findings are available in official reports published by CertiK and SlowMist. These documents include technical analysis and remediation steps taken.

Q: Does passing an audit mean the system is 100% secure?
A: No system can be guaranteed 100% secure. However, passing rigorous audits significantly reduces risks and demonstrates a proactive approach to identifying and fixing flaws.

Q: How does OKX Wallet protect my seed phrase?
A: Your seed phrase is encrypted and stored only on your local device. It is never transmitted over the network or saved on any server—even during cloud backups.

Commitment to Web3 Security

OKX Wallet continues to lead in delivering secure, multicoin support across 100+ blockchain networks, serving as a unified gateway to cross-chain DeFi trading, multi-market NFT platforms, and decentralized applications (dApps).
