NEXUS Co., Ltd, a company listed on South Korea’s KOSDAQ market and the developer of the CROSS blockchain gaming platform, has entered into a memorandum of understanding with CertiK, a globally recognized blockchain security firm. The collaboration reflects a growing emphasis on trust, security, and regulatory readiness as Web3 gaming platforms aim to reach mainstream audiences.
The agreement was announced on December 22, 2025, at a time when the CROSS ecosystem was undergoing active expansion. The timing underscores the increasing importance of robust security frameworks and compliance measures for blockchain-based gaming and payment solutions. The MOU was signed by NEXUS Chief Executive Officer Henry Chang and CertiK Co-founder and Chief Executive Officer Ronghui Gu, marking the beginning of a long-term strategic relationship between the two organizations.
NEXUS oversees the core infrastructure of the CROSS platform, including blockchain-based gaming services, a decentralized exchange, digital wallets, and creator-focused tools. The partnership arrives as the company prepares to introduce stablecoin-enabled payment systems designed to simplify in-game and service-related transactions. These developments make security and compliance critical priorities for the platform’s next phase of growth.
CertiK’s Security Expertise Supports Platform Expansion
CertiK has built a strong reputation in the Web3 sector for its smart contract audits, real-time risk detection, and continuous on-chain monitoring services. The firm has assessed more than 5,000 blockchain projects and plays a role in safeguarding digital assets valued at approximately $600 billion. Its client base includes major industry players such as Ethereum, Binance, and Tether, highlighting its influence and credibility within the blockchain ecosystem.
The partnership aligns with NEXUS’s strategy of embedding security into the platform from the earliest stages of development. As CROSS scales through the use of software development kits, application programming interfaces, wallets, and digital marketplaces, comprehensive protection is essential to prevent vulnerabilities. This need becomes even more pronounced with the introduction of stablecoins, where secure settlement and payment reliability are vital for user confidence.
Four Core Areas of Collaboration
Under the MOU, the partnership is structured around four primary pillars. The first focuses on security and smart contract auditing, with CertiK conducting in-depth reviews of CROSS components related to gaming, payments, and stablecoin contracts to ensure transparency and scalability.
The second area involves live on-chain risk monitoring. This includes continuous oversight of blockchain activity and smart contracts, along with the sharing of security intelligence to identify and mitigate threats before they escalate.

CROSS is supported by a team of more than 100 professionals specializing in blockchain technology and gaming. Through this partnership, the platform is expected to enhance payment security, strengthen user trust, and improve compliance across its ecosystem. As Web3 gaming continues to evolve, such measures are becoming essential for sustainable growth and broader adoption.

The firm has emphasized its commitment to building systems that combine innovation with resilience and transparency to support long-term growth.
From CertiK’s perspective, the partnership reflects the rising need for strong governance, compliance, and security as stablecoins and on-chain gaming gain traction. The company views its work with NEXUS as a meaningful step toward raising security standards across the Web3 industry and supporting the ecosystem’s continued innovation and maturity.
