Smart Contract Audit
Comprehensive smart contract security review covering logic flaws, economic attacks, and common vulnerability patterns. Conducted by engineers who build production DeFi protocols, not only auditors.

Deep protocol analysis
We review your contracts as protocol builders, not just auditors. We trace economic logic, trust assumptions, and upgrade paths, not limited to known vulnerability patterns.
Economic attack analysis
Flash loan attacks, price manipulation, sandwich attacks, MEV, oracle manipulation, and governance takeover vectors.
Tooling + fuzz testing
Static analysis with Slither and Mythril, property-based fuzz testing with Echidna or Foundry, and symbolic execution where applicable.
Remediation support
We stay engaged through the fix-and-verify cycle. You get a final verified report, not a list of issues to figure out yourself.
How we engage
The engagement process
Scope definition
We review your contracts, documentation, and deployment setup. We define the trust model and the threat surface.
Review & analysis
We trace economic logic, trust assumptions, and upgrade paths alongside static analysis, fuzz testing, and symbolic execution.
Findings report
Detailed report with severity classification, reproduction steps, and recommended fixes.
Fix verification
We verify developer fixes and issue an updated report. The audit is complete when all Critical and High findings are resolved.
Builder perspective, not auditor checklist
Our engineers build DeFi systems for clients. We recognise attack vectors from the inside: not from a vulnerability checklist, but from having written the same code.
We model the attack, not just the bug
A vulnerability is only a critical finding if it is economically viable to exploit. We model attack profitability against protocol liquidity and market conditions before assigning severity.
Post-remediation verification included
Every audit includes a fix verification pass. You get a final clean report you can publish. No separate charge for re-review.

Get in touchWe audit Solidity on EVM chains (Ethereum, Arbitrum, Base, Optimism, Polygon), Rust/Anchor on Solana, and have coverage on MultiversX and NEAR. If you are on a different chain or VM, tell us and we will assess coverage honestly.
Yes. Our reports follow the same structure as leading audit firms: severity classification, findings detail, proof-of-concept, and remediation guidance. Most launchpads and institutional investors accept our reports. If you need a specific format, let us know upfront.
Yes. Second-opinion audits are valuable, especially before major protocol upgrades or large treasury deployments. We approach these without anchoring to the first report findings.
Automated tools are good at catching known patterns but miss logic bugs specific to your protocol design. Manual review is the core of what makes an audit valuable. We use tools to supplement the manual pass, not replace it.
