Blockchain Security Audit
Security review for the contract layer and the surrounding blockchain system: protocol design, message flows, privileged operations, off-chain services, and deployment assumptions.
A blockchain security audit is broader than reading contract files in isolation. Protocols often fail where smart contracts meet bridges, indexers, relayers, front ends, signing flows, APIs, and governance operations.
CTDSEC keeps smart contract auditing as the center of the review while tracing the surrounding system for assumptions that can change the real attack surface.
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
Blockchain Security Audit with manual review, tool-assisted coverage, and remediation support.
Audit Coverage
- Smart contract and protocol architecture
- Cross-chain messages, bridges, relayers, and proof assumptions
- Wallet, signer, key, and admin-operation workflows
- Backend services that affect contract state or user signing
- Token, staking, reward, and treasury movements
- Deployment, verification, monitoring, and incident readiness

Smart Contract Audit FAQ
Short answers for teams preparing an audit scope.
What does a blockchain security 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 blockchain security audit priced?
