Security Audit Reports Overview

·

In the fast-evolving world of Web3 and blockchain technology, security remains a top priority for both users and developers. As decentralized applications (dApps), digital wallets, and NFT marketplaces grow in popularity, ensuring robust protection against vulnerabilities is essential. This comprehensive overview details the independent security audits conducted on key components of a leading Web3 infrastructure — focusing on transparency, risk mitigation, and trust-building through third-party verification.

The following sections present audit findings from globally recognized cybersecurity firms CertiK and SlowMist, covering critical modules such as wallet applications, smart contracts, MPC-based keyless systems, and NFT trading functionalities. All identified issues have been addressed, reinforcing the platform's commitment to user safety and system integrity.

CertiK Security Audits

CertiK is one of the most trusted names in blockchain security, known for its advanced formal verification techniques and rigorous manual code reviews. Multiple components of the OKX Web3 ecosystem have undergone thorough evaluation by CertiK, with consistently positive outcomes.

Audit of OKX Wallet App, Frontend, and SDK Modules – May 2024

The OKX Wallet mobile application, along with its frontend interface and core software development kits (SDKs), successfully passed a comprehensive audit by CertiK. The assessment concluded that the system is secure overall, identifying only three low-risk findings and two improvement suggestions — all of which have since been fully resolved.

Audit of OKX Wallet Threshold-LID – October 2023

The Threshold-LID module, a decentralized identity solution leveraging threshold cryptography, was audited for potential vulnerabilities in logic flow, access control, and cryptographic implementation.

While specific details of the findings are not publicly disclosed in full, the final report confirmed that:

This module plays a crucial role in enabling secure, non-custodial user authentication without reliance on centralized identity providers.

Audit of OKX Wallet Main Contracts – May 2023

Core smart contracts powering the OKX Web3 Wallet underwent an extensive review by CertiK. These contracts govern fundamental operations such as asset management, transaction signing, and cross-chain interactions.

Key Findings

Smart contract security is paramount — even small bugs can lead to irreversible fund losses. This successful audit demonstrates adherence to best practices in smart contract development and deployment.

Audit of OKX Wallet Marketplace Solana NFT Trading – July 2022

With the rise of NFTs on the Solana blockchain, secure marketplace operations became increasingly important. This audit focused on the Solana-based NFT trading engine within the OKX Wallet ecosystem.

Results Summary

All actionable items were resolved prior to general availability, ensuring safe peer-to-peer NFT transactions with proper validation of metadata, ownership proofs, and transfer logic.

SlowMist Security Audits

SlowMist is another industry-leading security firm specializing in blockchain threat intelligence and penetration testing. Their audits provide deep insights into runtime behavior, side-channel attacks, and real-world exploit scenarios.

Audit of Account Abstraction (AA) Smart Contract – June 2023

Account Abstraction enhances user experience by allowing flexible transaction logic, such as gasless transactions and multi-factor authentication. However, it also introduces new attack surfaces.

The AA smart contract module was evaluated for:

✅ Result: No critical vulnerabilities found
🔧 All minor findings were remediated post-audit

This confirms that the implementation aligns with Ethereum ERC-4337 standards while maintaining strong defensive mechanisms.

Audit of MPC Keyless Wallet (Android & iOS) – May 2023

The Multi-Party Computation (MPC) keyless wallet eliminates traditional private key storage by distributing key shares between the user device and secure nodes. This significantly reduces the risk of theft or loss.

Separate audits were conducted for:

Both versions passed with favorable results:

Users benefit from enhanced convenience without sacrificing control over their assets.

Audit of Ordinals Transaction Module – May 2023

As Bitcoin Ordinals gained traction, secure support for inscriptions became essential. The Ordinals transaction module enables safe creation, transfer, and viewing of ordinal-based digital artifacts.

The audit focused on:

All findings were classified as informational or low-risk, with appropriate mitigations applied. This ensures reliable handling of Bitcoin-native assets within the wallet interface.

Audit of Private Key Security Module – October 2022

One of the most critical aspects of any cryptocurrency wallet is how it handles private keys. This audit specifically verified the following:

🔐 "Private keys or seed phrases are stored exclusively on the user’s local device."
🚫 "Under no circumstances are private keys or recovery phrases transmitted to external servers."

These principles are foundational to non-custodial wallet design. The audit confirmed strict enforcement of these rules across all platforms and backup processes.

Additionally:

This creates a trusted environment where users maintain full ownership of their digital identities.

Frequently Asked Questions (FAQ)

Q: What does a 'secure' audit result mean?
A: A 'secure' outcome indicates that no critical or high-risk vulnerabilities were found that could compromise funds or user data. Minor issues may exist but are typically non-exploitable in practice and are often resolved proactively.

Q: Are all audit reports publicly available?
A: While full technical reports may be restricted due to sensitive details, summary results and verification statuses are typically shared transparently to build community trust.

Q: How often are these systems re-audited?
A: Major updates trigger new audits. Additionally, routine penetration tests and continuous monitoring help maintain long-term security hygiene.

Q: Does passing an audit guarantee 100% safety?
A: No system can offer absolute guarantees. However, third-party audits significantly reduce risks by uncovering hidden flaws before malicious actors can exploit them.

Q: What is MPC in the context of wallets?
A: Multi-Party Computation (MPC) allows cryptographic operations to occur without ever reconstructing a full private key, distributing trust across multiple parties or devices.

Q: Why are private keys never sent to servers?
A: Sending private keys to servers would make them custodial wallets. True decentralization requires users to retain sole control — a principle strictly upheld in this architecture.
