Smart Contract Security Review & Subscription Auditing

Shieldify provides comprehensive smart contract audit services for Web3 protocols and DeFi projects, delivered through two engagement models: a Single Security Review for one-time comprehensive audits and a Subscription-Based Model for protocols requiring continuous security coverage.

Single Security Review

A fully-fledged smart contract audit in which a team of experienced security researchers independently audit the entire codebase in parallel, then combine their findings into one consolidated final report. The review covers:

• Full codebase audit with multi-researcher parallel review
• Vulnerability detection across logic flaws, access control issues, reentrancy, oracle manipulation, and MEV exposure
• Review of deploy scripts and fix implementations (Migration Review)
• Final consolidated report assembled from each researcher's individual findings

With 150+ security reviews completed and 1,000+ vulnerabilities detected, Shieldify's 6-layered security approach delivers thorough, authoritative audit reports for protocols preparing for mainnet deployment or significant code changes.

Subscription-Based Auditing

Shieldify's flagship subscription model entitles clients to unlimited smart contract audits within the subscription duration, regardless of the number or size of contracts being reviewed. It includes all features of the Single Security Review, plus:

• Unlimited audits with no caps on contract size or count
• Hibernate option — pause the subscription without losing time, ideal for between major releases
• Fuzzing and Formal Verification as add-ons for advanced assurance

This model is designed for protocols undergoing rapid iteration, continuous feature releases, or maintaining multiple smart contract systems simultaneously.

Fuzz Testing & Invariant Testing

As a complement to manual code review, Shieldify offers fuzz testing and invariant testing — both available as add-ons to the subscription or as standalone engagements. Fuzz testing submits large volumes of random and malformed inputs to discover edge cases, arithmetic overflows, and unexpected state transitions. Invariant testing defines and verifies properties that must always hold true for a protocol, surfacing deep logical vulnerabilities in complex DeFi systems.
