FAQ
What makes Spearbit's smart contract reviews different from other audit providers?
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.
How is the scope of a smart contract review determined?
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.
What types of vulnerabilities do you typically identify?
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.
How long does a smart contract review typically take?
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.
Will we have access to the researchers during the engagement?
Yes. Spearbit engagements are highly collaborative. Your team will have a direct line of communication with assigned researchers, with updates and clarification cycles built into the process.
What does the final report include?
The report includes a detailed list of identified issues, categorized by severity, with technical explanations, reproduction steps, and remediation guidance. Reports also include contextual risk assessments and a summary of the protocol's overall security posture.
Do you provide support after the review is completed?
Yes. We offer post-review support to answer questions, re-evaluate fixes, and help ensure vulnerabilities have been correctly resolved. Our goal is not just to deliver findings, but to help your team act on them effectively.
Can you re-review fixes or changes made after the initial audit?
Absolutely. We support fix validation and optional follow-up reviews, especially when critical or high-severity issues are involved. We can also conduct ongoing reviews as your protocol evolves.
What experience does Spearbit have with high-value or complex deployments?
Spearbit has reviewed mission-critical infrastructure for Layer 1 and Layer 2 chains, modular systems, and DeFi protocols with billions in total value locked. Our researchers are trusted by the most security-conscious teams in Web3.
