Web3 security, made decisive
Independent smart contract and protocol security reviews built for teams that need to launch with confidence. We examine critical logic, attack surfaces and system assumptions—then turn every finding into a clear path to remediation.
Security services
No two protocols fail in exactly the same way. The right engagement depends on your architecture, release stage, threat model and the value your contracts are expected to secure.
A confidential, deeply scoped assessment for teams preparing a launch, migration or major protocol upgrade.
A coordinated review format designed to bring multiple security perspectives to large or complex codebases.
Ongoing review support for protocols that evolve through upgrades, governance decisions and new integrations.
How an engagement works
Security work is most useful when expectations are precise. Every engagement begins with the system you are building, the code that matters and the risks that would be unacceptable.
We review the architecture, repositories, documentation, deployment assumptions and timing to define a clear assessment boundary.
We map privileged roles, trust boundaries, value flows, external dependencies and the actions an attacker could attempt.
The code is examined for implementation flaws, broken invariants, unexpected state transitions and protocol-level failure modes.
Potential issues are reproduced, challenged and ranked by exploitability, impact and the conditions required for abuse.
You receive a concise technical report with evidence, affected components, risk explanations and practical remediation guidance.
Implemented fixes are re-examined so the final outcome reflects the code that is actually intended for deployment.
What we examine
Automated tools can surface patterns. A meaningful security review also asks whether the protocol behaves safely under pressure, whether its assumptions hold and whether incentives can be turned against it.
The goal is not to produce more findings. It is to reduce uncertainty before real value is at risk.
Common questions
A useful estimate starts with a clear picture of the codebase, release stage and desired timeline.
Ideally, once the architecture is stable and the code is close to feature-complete, but before a fixed launch date leaves no room for remediation. Early contact also makes it easier to reserve the right review window.
A repository or code snapshot, approximate lines of relevant code, supported chains, technical documentation, audit history, desired dates and a short description of the protocol are usually enough to begin scoping.
No review can guarantee the absence of every vulnerability. An audit reduces risk within a defined scope and point in time. Operational security, monitoring, access control and careful change management remain essential after the review.
Yes. Remediation review confirms whether reported issues were addressed and checks whether the changes introduced additional concerns within the agreed scope.
Private audits can be handled confidentially. Disclosure timing, report publication and any public references should be agreed during scoping.
