Spearbit

Spearbit emerged as a solution to a critical gap in Web3: the need for deep, domain-specific security expertise that goes beyond generic audits. As the blockchain industry matures and the surface area of smart contracts and infrastructure grows, point-in-time audits are no longer enough. Teams need access to specialists who understand their protocol inside and out—people who can anticipate vulnerabilities and design proactive defenses from day one.

Offered exclusively on Cantina, the Spearbit model is built on precision, flexibility, and performance. Unlike automated scanners or generic audit firms, Spearbit assembles tailored security teams based on the needs of each engagement. From protocol design reviewers to validator engineers, from penetration testers to DeFi veterans, every researcher is individually selected to align with the project’s scope and risk profile.

The scope of services covers the full security lifecycle. With Advisory, teams gain access to long-term strategic security partners. With Smart Contract Reviews, the most critical parts of code are reviewed through layered, manual assessments. Advanced Security Assessments simulate real-world attack vectors, including economic exploits and oracle manipulation. Teams building hybrid applications or traditional infrastructure can also engage Spearbit for Web2 Security Reviews and Penetration Testing, ensuring every attack surface is covered.

Over time, Spearbit has earned the trust of top protocols across DeFi, L2s, NFTs, and enterprise blockchain. Partners include Uniswap, zkSync, Morpho, Optimism, and Polygon. Spearbit’s hand-picked researchers—including names like Eric Wang, Kurt Barry, Christoph Michel, 0xicingdeath, zigtur, and Paweł Bylica—are widely recognized as the best in the industry.

While other firms rely on static teams or fixed methodologies, Spearbit evolves with your protocol. Whether you’re launching, scaling, upgrading, or defending, the Spearbit network integrates seamlessly into your workflow to provide real-time, human-driven protection for everything you’re building.
