Once deployed, there is no undo button.
Smart contracts are immutable by design. A single vulnerability can expose funds, break logic, or permanently damage trust.
Our audits identify vulnerabilities, logic flaws, and optimisation issues before deployment across DeFi platforms, NFT projects, Web3 applications, DAOs, and enterprise systems — deep manual reviews focused on real attack vectors, business logic risks, and production readiness.
- Security vulnerabilities
- Business logic correctness
- Gas efficiency
- Upgradeability & permissions
It isn't six services. It's one review.

Token Smart Contract Audits
Audits for ERC-20, ERC-721, ERC-1155, and custom token standards, including supply control, permissions, and transfer logic — the layer everything else is built on.

Every stage runs commands and has to return clean output before the next one starts. Step through it below.
Pipeline stages
We review contract purpose, architecture, and intended behaviour to understand risk exposure and attack surfaces before reading a single function in detail.

How deep an audit has to go depends on what is exposed.

Typically
full manual audit · remediation review
We audit for how contracts fail in practice.
Auditing is not a checkbox exercise. These are the ways an audit itself fails the team that paid for it — and what we do instead. We focus on preventing exploits, not just reporting them.
The automated-only audit
A tool report reformatted into a PDF and sold as a security review.
Manual line-by-line review is the audit; tooling is a safety net beneath it. Automated findings are triaged by an auditor, and no finding reaches your report unverified.
Findings nobody can act on
A severity label, a line number, and no explanation of what to actually do.
Every finding carries a reproduction, the conditions that trigger it, the impact in business terms, and concrete remediation guidance — written to be handed straight to a developer.
Correct code, wrong behaviour
A contract with no bugs that still does not do what the protocol intended.
We validate intent, not just implementation — modelling how the contract behaves under edge cases, adversarial users, and economic pressure on a mainnet fork.
Fixes that break something else
A patch applied after the audit, deployed without anyone looking at it again.
Remediation review re-checks each fix against the original finding and diffs the change for regressions, so the version you deploy is the version that was actually audited.
Scope that quietly excludes the risk
An audit that technically passed because the dangerous contract was never in it.
Scope and trust boundaries are agreed in writing at the start, and anything excluded is named explicitly in the report rather than left for a reader to assume.

The stack behind the platforms we build.
We choose tools for the outcome they deliver, not for the trend they follow.

Smart Contract Audit FAQs
Everything you might want to know before we talk. Still unsure? A quick call clears it up.
Ask us anythingA smart contract audit is a detailed review of blockchain code to identify security vulnerabilities, logic errors, and inefficiencies before deployment.
We primarily audit Solidity-based contracts on Ethereum and EVM-compatible chains. Other environments can be reviewed on request.
Most audits take 1–3 weeks depending on code size, complexity, and scope.
Yes. We provide remediation guidance and can review fixes to confirm vulnerabilities are resolved.
Yes. Our audit reports are suitable for due diligence, partner review, and public disclosure.
