CosmWasm Smart Contract Audit
Rust smart contract auditing for CosmWasm code deployed across Cosmos ecosystems, with attention to storage, messages, permissions, IBC, and protocol logic.
CosmWasm contracts run in a different model from EVM contracts and Solana programs. Audits must account for messages, storage keys, instantiate and migrate flows, reply handling, IBC callbacks, and chain-specific module interactions.
CTDSEC reviews CosmWasm contracts as Rust code and as part of the broader Cosmos execution environment.
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
CosmWasm Smart Contract Audit with manual review, tool-assisted coverage, and remediation support.
Audit Coverage
- Instantiate, execute, query, migrate, reply, and sudo entry points
- Storage layout, key namespaces, and state migration
- Authorization, admin controls, and DAO/governance permissions
- IBC messages, callbacks, channel validation, and cross-chain state
- Arithmetic, token accounting, and DeFi invariants
- Dependency, serialization, and Rust implementation risks
Risk Areas
- Unsafe migrations or admin permissions
- IBC callback assumptions that attackers can influence
- Storage collision or incorrect key handling
- Authorization bypass through message routing
- Precision or accounting mistakes in DeFi contracts
Deliverables
- CosmWasm-specific code findings
- Rust and Cosmos runtime risk notes
- Remediation guidance for migrations, permissions, and IBC
- Final audit report and optional retesting

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