Memory Safety
Even with Rust’s ownership model, unsafe blocks can introduce use-after-free, buffer overflows, and dangling references.
- Unsafe block auditing
- Raw pointer dereferences
- Buffer boundary violations
- Lifetime and borrow violations
Smart Contract Audits
Rust Audit
Security audits for Rust-based blockchain applications and smart contracts. We focus on memory safety, concurrency issues, unsafe code patterns, and blockchain-specific vulnerabilities.
What We Cover
Every critical attack surface in Rust blockchain code, reviewed manually
Concurrency & Race Conditions
Rust prevents data races at compile time, but logical race conditions and TOCTOU bugs can still affect blockchain state.
- TOCTOU vulnerabilities
- Mutex poisoning paths
- Async cancellation safety
- Shared state ordering issues
Arithmetic & Overflow
Checked arithmetic is the default in debug builds but not always in release. We verify every arithmetic operation in critical paths.
- Wrapping vs saturating arithmetic
- Integer overflow in release mode
- Precision loss in fixed-point math
- Division by zero paths
Solana Program Security
For Anchor and native Solana programs, we audit account validation, CPI safety, and program-derived address handling.
- Missing signer / owner checks
- Account data reuse attacks
- CPI privilege escalation
- PDA bump seed validation
Access Control & Authorization
Authorization logic that is correct in unit tests can fail under real-world conditions. We stress test every privilege boundary.
- Missing authority validation
- Signer spoofing
- Privilege escalation via CPI
- Admin key exposure
Serialization & Deserialization
Borsh, bincode, and serde can behave unexpectedly with malformed inputs or versioned data structures.
- Malformed input handling
- Discriminator collision
- Versioning upgrade safety
- Canonical serialization enforcement
