Octane Raises $6.75M to Reinvent Blockchain Security (2025)

Octane, a cybersecurity startup focused on blockchain applications, has secured $6.75 million in seed funding to accelerate its mission of improving the security of decentralized finance ecosystems. The funding round was jointly led by Archetype and Winklevoss Capital, with participation from several prominent players in the crypto and fintech industries including Gemini, Circle, Legion Capital, Druid Ventures, and Duke Capital Partners. The round also attracted investments from well-known individual backers such as Balaji Srinivasan and Sina Habibian.

The startup is tackling one of the crypto sector’s most critical pain points: vulnerability in blockchain codebases. With crypto-related hacks surpassing $11 billion according to data from DefiLlama, the urgency for improved security measures has grown significantly. Smart contracts, the backbone of decentralized platforms, are increasingly targeted by attackers due to their integral role in handling high-value transactions. The risk is compounded by the speed and anonymity offered by blockchain systems, which enable hackers to move stolen funds with minimal resistance.

Proactive Security Powered by Artificial Intelligence

Octane has developed an AI-driven solution aimed at bridging a long-standing security gap in blockchain development. The platform continuously scans on-chain smart contracts, using machine learning algorithms to detect and correct flaws before malicious actors can exploit them. This real-time analysis is designed to aid developers throughout the software development lifecycle—both before deployment and after integration—making the system not only preventative but also adaptive.

The company’s leadership highlighted that the current threat landscape, driven by flawed code and expanding financial activity in decentralized networks, demands a smarter approach. Octane’s platform is geared toward enabling developers to eliminate vulnerabilities proactively, through automated threat detection and simple one-click bug fixes. Plans are also in motion to extend the platform’s capabilities to off-chain codebases, allowing a broader range of applications to benefit from its tools.

Strategic Investment to Drive Growth

The new capital injection will be directed toward accelerating product development, growing the team, and expanding the platform’s reach among crypto developers. A key area of focus involves mass labeling vulnerability data to improve the training of Octane’s machine learning models. Additionally, the company is working to distribute its platform widely across the developer ecosystem, aiming to become a standard security tool in Web3 application development.

Backers of the company underscored the transformative potential of Octane’s technology. Investors noted that Octane’s AI-powered approach gives developers the ability to stress-test smart contracts prior to deployment, significantly enhancing the robustness of blockchain applications. This, in their view, not only benefits individual developers and companies but also contributes to broader crypto adoption by building user trust.

Octane’s supporters emphasized that improving smart contract security is paramount to the next phase of crypto evolution. The team’s approach, which combines developer-first design with advanced AI models, is seen as a step forward from traditional security audits, offering a more dynamic and scalable solution to one of crypto’s most persistent issues.

A Safer Future for Web3 Development

As the blockchain landscape matures, the stakes around cybersecurity continue to rise. Octane’s entry into the market introduces an innovative path forward, where automated, intelligent systems help secure an industry increasingly under threat from technical vulnerabilities. The firm’s strategy of embedding security directly into the development process positions it as a crucial player in the ongoing effort to build a safer and more resilient Web3 ecosystem.
