Anchor Smart Contract Audit
Focused Solana Anchor audits for teams that need account constraints, PDA derivation, signer validation, CPI behavior, and instruction logic reviewed before mainnet risk.
Anchor improves Solana developer ergonomics, but security still depends on how constraints, seeds, accounts, authorities, and cross-program calls are modeled.
CTDSEC reviews Anchor programs at the macro and instruction level, checking that declarative constraints match the protocol's real invariants.
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
Anchor Smart Contract Audit with manual review, tool-assisted coverage, and remediation support.
Audit Coverage
- Account constraints, seeds, bumps, and PDA authority
- Signer, owner, executable, and mutability checks
- CPI targets, remaining accounts, and arbitrary CPI risk
- Initialization, closing, realloc, and rent-related logic
- Serialization, account versioning, and state validation
- Business logic, arithmetic, and test coverage
Risk Areas
- Constraint omissions that allow account substitution
- PDA mismatch or unauthorized signer behavior
- Arbitrary CPI and remaining-account confusion
- Unsafe account initialization or close flows
- Incorrect assumptions about Anchor defaults
Deliverables
- Anchor-specific findings and account-flow notes
- Instruction-level remediation guidance
- Recommendations for stronger tests and constraints
- Final audit report with Solana context

Smart Contract Audit FAQ
Short answers for teams preparing an audit scope.
What does a anchor 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.
