Most contract failures don't start in the code. They start in the audit.
A clean audit report does not mean clean code. It means whoever reviewed it ran the usual tools and found nothing. That is not the same as security, and the difference is where the money gets lost.
✕ A script ran, a PDF came back, and someone called it a review.
✕ A junior did the work. The senior name on the cover never opened the repo.
✕ Findings came back vague. No severity, no reproduction steps, no fix.
✕ The audit shipped on time, and the bug shipped right alongside it.
You are launching with real money on the line. Investors expect security. Users expect security. Your name is attached to all of it. A weak audit quietly puts the three at risk and you find out the hard way. An audit should be done right, not just done. Here is what that looks like.
Five layers, applied to every contract regardless of size
Tools catch the known patterns fast. Senior engineers catch the things tools were never built to see. We run both, in this order.
Static analysis
Slither and Mythril flag known vulnerability classes and dangerous patterns across the codebase.
Slither · MythrilFuzzing and symbolic execution
Echidna and Foundry hammer your invariants with inputs your test suite never tried.
Echidna · FoundryManual line-by-line review
Two senior auditors read every line, focused on business-logic and economic flaws that no tool detects.
Two senior auditorsFormal verification (on request)
Certora proofs on the critical paths, where a single wrong assumption drains the protocol.
CertoraRemediation and re-audit
We verify each fix and confirm it did not open a new hole.
Fix verificationWhat you get, not just what we do
Every engagement ends with a report your team can publish on the repo, hand to investors, and attach to the launch post. It contains:
→ Every finding rated Critical, High, Medium, Low, or Informational.
→ For each finding: reproduction steps, the impact if exploited, and a concrete recommended fix.
→ A fix-verification section confirming what was remediated and re-checked.
→ The exact tools, versions, and commit hashes reviewed, so the audit is reproducible.
→ The named auditors, their credentials, and our signed attestation.
From a single contract to a full protocol
Solidity, Rust, and Move. Each category lists a typical timeline so you can self-qualify before a call.
DeFi protocols
Lending, AMMs, perpetuals, options, yield aggregators. Multi-contract systems with composability risk.
3 to 8 weeks
Token contracts
ERC-20, BEP-20, SPL, ERC-3643, ERC-721, with vesting, staking, and transfer restrictions.
1 to 2 weeks
Tokenization platforms
Security tokens, real-world asset tokens, transfer-agent integrations. Compliance-aware.
4 to 8 weeks
Wallet contracts
Custodial and non-custodial logic, MPC integrations, account abstraction (ERC-4337).
2 to 4 weeks
NFT and marketplace contracts
Royalty enforcement, auctions, lazy minting.
2 to 4 weeks
Bridges and L2 contracts
Cross-chain messaging and settlement. The highest-risk category we audit.
4 to 10 weeks
Scoping first. Everything else locks after.
Week 1, scoping
We review the codebase, define scope, map dependencies, and lock a fixed price.
You get: A written scope and fixed quote you keep, whether or not you continue.Weeks 2 to 3, audit
Two senior auditors run the full five-layer pass.
You get: A preliminary findings report.Week 4, findings review
We walk your team through each finding, severity, and fix.
You get: A detailed findings document.Week 5, fix verification
You implement, we re-audit the changes and confirm no regressions.
You get: A fix-verification report.Week 6, final report
Publishable report with our attestation.
You get: The final PDF and signed attestation.A sample of recent work
Pre-mainnet audit before token launch
Pre-mainnet audit on the contracts in 4 weeks before token launch. Multi-tool plus manual review of the full Solidity codebase, surfacing critical and high findings. All remediated, launched on time, with no incidents since.
Security-token audit before a Reg D filing
A Reg D security-token contract needed an audit before filing. Six-week review including the regulatory framework and Securitize integration. The audit passed and the team put the report in their raise deck.
References available under NDA. We link each engagement to a full case study once the client approves disclosure.
Read the case studies →Why teams choose us
→ Senior auditors only
Every audit is led by an engineer with 5+ years of Solidity and at least 20 prior audits. We do not put juniors on your code, and their names are on the report.
→ Audit-first, not bolt-on
We design for security from week 1. Our pre-mainnet checklist covers every item with a documented fix path.
→ Fixed fee, no scope creep
Price locks in writing after scoping. If the codebase grows mid-engagement, we re-scope before we continue, not after.
→ Post-launch guarantee
If we miss a Critical or High finding and you hit it within 90 days of launch, we audit the fix at no charge and help with the disclosure. It is written into every contract.
Frequently asked questions
A standard audit on 5 to 15 contracts runs 2 to 4 weeks: a week of scoping, two to three weeks of audit, plus a remediation cycle. Complex protocols needing formal verification run 4 to 8 weeks. We lock your timeline in writing during scoping.
Slither and Mythril for static analysis, Echidna and Foundry for fuzzing, manual review by two senior auditors, and Certora for formal verification on request. Every report lists the exact tools and versions.
You do. Publish it, share it with investors, or attach it to your launch. We may reference the engagement in our portfolio only with your permission.
If we miss a Critical or High finding and you hit it within 90 days of launch, we audit the fix at no charge and help with disclosure. This is in every contract.
Yes, a mutual NDA before any code review, covering your code, business model, and investor information.
Yes. Solidity on Ethereum, Base, Arbitrum, Optimism, Polygon, and zkSync; Rust on Solana, Near, and Aptos; Move on Sui and Aptos. Move and Rust sometimes run slightly longer due to tooling.
