Spearbit delivers bespoke reviews led by elite, hand-selected researchers who specialize in deep, manual security analysis. Our process goes beyond surface-level checks to uncover architectural weaknesses, specific edge cases, and logic flaws that typical audits miss.
We define the scope collaboratively with your team. This includes understanding your protocol's architecture, business logic, deployment timeline, and areas of concern. The scope covers contract complexity, lines of code, dependencies, and any high-risk modules.
We look for a wide range of vulnerabilities, including re-entrancy, logic errors, privilege escalation, oracle manipulation, denial of service, access control misconfigurations, and issues with upgradeability or dependency management. We also assess broader protocol-level risks.
Timelines vary depending on the scope and complexity of your codebase. We'll provide a timeline during the initial consultation and can accommodate urgent timelines when needed.
