Audit engine

The orchestration layer for AI-native security review. Coordinates the strongest available AI security approaches against your code and turns their output into one validated audit result.

Collaborative Audits

Private, staffed audits led by top-performing Web3 security researchers. Sherlock assembles a curated team to review your codebase in a dedicated engagement, helping your team find critical vulnerabilities before mainnet.

Audit Contests

Sherlock’s contests apply large-scale adversarial pressure to your code, with top auditors competing to surface the most impactful issues as fast as possible.

Bug Bounties

Sherlock’s bug bounties create an active incentive layer on your live code, bringing experienced hunters to test it while Sherlock’s in-house team triages findings as they come in.

Trusted By
Leading protocol Teams

Aave has always implemented industry-leading security standards. V4 is designed to bring trillions of dollars and millions of users onchain, so continuing to meet those standards was not negotiable. Sherlock’s collaborative audit provided a deep review from a specialized team, and the public contest that followed confirmed their work was effective.

Stani Kulechov - Founder and CEO of Aave Labs

Rock solid security has always been a priority for Sky. Over time, it's become one of the defining features of the project. It only makes sense that the team would work with the market leader, Sherlock.

Rune Christiansen - Founder of Sky

We chose Sherlock because we were intrigued by the value of having multiple independent security researchers collaborating together. Our favorite part was the collaborative environment and effective feedback cycle between our team and Sherlock, making it a very productive experience.

faq

What is Sherlock?
Sherlock is a security company for onchain systems. We help protocols, institutions, and infrastructure teams secure critical systems across development, launch, and live operation through expert-led and AI-native security reviews.
How is Sherlock different from a traditional audit firm?
Sherlock brings multiple security approaches into one lifecycle model, combining elite security researchers, AI-native auditing, competitive review, and post-launch security. Teams can use each offering independently or combine them across the lifecycle of a system.
Does Sherlock only work with teams that want end-to-end security coverage?
No. Teams can engage Sherlock for a single security need or use multiple offerings as their systems evolve.
What security services does Sherlock offer?
Sherlock offers security services across every stage of a protocol’s lifecycle, including collaborative private audits, AI-native reviews through Audit Engine, open audit contests, and post-launch bug bounties. Teams can use individual services or combine them for continuous security coverage from development through live operation.
Who is Sherlock built for?
Sherlock works with protocols, institutions, infrastructure providers, asset managers, L1s and L2s, bridges, vaults, and other teams responsible for high-value onchain systems.
Why does Sherlock use a lifecycle security model?
Security risk exists throughout the life of an onchain system. Sherlock’s lifecycle model connects different forms of security review across development, launch, and live operation so teams can apply the right level of protection at each stage.
