Smart Contract Security Reviews & Advanced Assessments

Spearbit delivers the highest caliber of smart contract security review available, combining elite manual code analysis with advanced specialized assessments for mission-critical blockchain infrastructure.

Smart Contract Security Reviews

Spearbit's flagship offering — bespoke, deep manual code reviews conducted by hand-selected elite researchers. Every review mandates a minimum of two Lead Security Researchers, ensuring depth and specialization across even the most complex decentralized systems. Researchers are matched based on technical fit across Solidity, Rust, Cairo, Move, and other smart contract languages on EVM-compatible and non-EVM chains.

To date, Spearbit has completed 282 reviews, found over 4,500 vulnerabilities, and secured 119 projects handling billions in total value locked.

What's Included

• Initial consultation and scoping tailored to protocol architecture
• Deep manual analysis complemented by advanced automated tooling
• Comprehensive reporting with severity categorizations and remediation steps
• Post-review support for fix verification and re-review of changes
• Coverage of re-entrancy, logic errors, privilege escalation, oracle manipulation, access control, upgradeability, and protocol-level risks

Advanced Security Assessments

For protocols where traditional audits leave critical blind spots, Spearbit's Advanced Assessments deliver specialized evaluations:

• Threat Modeling: Maps architecture, pinpoints attack vectors, and anticipates adversary behaviors
• Architectural Security Review: Big-picture evaluation covering dependencies, contract interactions, and off-chain components
• Fuzzing & Unit Testing: Automated fuzzing to uncover deep-seated flaws that manual reviews miss
