Solidity Smart Contract Audit
Manual Solidity review for EVM projects that need precise coverage of contract logic, upgradeability, storage, calls, and production deployment risk.
Solidity audits must combine known vulnerability checks with protocol-specific reasoning. CTDSEC reviews the code and the behavior that emerges when contracts interact with markets, governance, bridges, proxies, or external protocols.
The review includes both automated analysis and manual inspection of high-impact paths that automated tools often cannot understand.
What CTDSEC reviews
The review is tailored to the target chain and codebase, but the audit always starts with assets at risk, trust boundaries, and the concrete ways the protocol can fail.
Audit focus
Solidity Smart Contract Audit with manual review, tool-assisted coverage, and remediation support.
Audit Coverage
- Reentrancy, callback behavior, and checks-effects-interactions violations
- Access control, owner authority, role revocation, and timelocks
- Proxy patterns, storage layout, initialization, and upgrade safety
- Oracle integration, decimal handling, stale data, and price manipulation
- Signature verification, permits, replay protection, and chain IDs
- Token, vault, reward, and accounting invariants
Risk Areas
- Loss of funds through reentrancy or unsafe external calls
- Permanent proxy or initialization mistakes
- Arithmetic, precision, and rounding errors in financial code
- Oracle manipulation and flash-loan-assisted attacks
- Access-control paths that bypass intended governance
Deliverables
- Commit-pinned audit scope
- Manual Solidity findings with severity and exploitability
- Tool-assisted analysis notes
- Remediation support and optional fix verification

Smart Contract Audit FAQ
Short answers for teams preparing an audit scope.
What does a solidity smart contract audit include?
It includes scope confirmation, manual code review, tool-assisted analysis where useful, severity-ranked findings, remediation guidance, and a final report for the agreed disclosure model.
Can CTDSEC review fixes after the audit?
Yes. Fix verification can be included after the team remediates reported findings, using a new commit and a clear change summary.
How is a solidity smart contract audit priced?
