Smart contract security

Rust Smart Contract Audit

Deep Rust security review for smart contracts and blockchain protocols, with special attention to Solana, Anchor, CosmWasm, NEAR, and Substrate environments.

Request a Smart Contract Audit Review the Methodology

Rust smart contract security is not the same problem as ordinary backend Rust. The audit has to account for account models, serialization boundaries, signer validation, ownership checks, cross-program calls, state transitions, and runtime-specific constraints.

CTDSEC treats Rust as a major smart contract auditing specialization while keeping the broader goal clear: protect protocol assets and users across any chain.

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

Rust Smart Contract Audit with manual review, tool-assisted coverage, and remediation support.

Manual reviewTool-assistedRemediation support

Audit Coverage

Unsafe Rust usage, dependency risk, and supply-chain assumptions
Integer arithmetic, overflow behavior, precision, and rounding
Serialization, deserialization, account layouts, and state validation
Signer validation, ownership checks, PDA validation, and access control
CPI security, arbitrary CPI, account confusion, and initialization paths
Cryptographic implementation risk and performance-security tradeoffs

Risk Areas

Account substitution or missing ownership checks
Incorrect PDA seeds, bumps, or authority derivation
State deserialization that accepts invalid or hostile data
CPI calls that trust attacker-controlled programs
Dependency or unsafe-code behavior outside normal test coverage

Deliverables

Rust-specific code review and runtime threat model
Finding details with exact validation and state-transition context
Remediation guidance for Solana, Anchor, CosmWasm, NEAR, or Substrate code
Optional verification of patched Rust contracts
