Rust Smart Contract & Solana Program Audits
Rust-based blockchains introduce a fundamentally different security model from the EVM. Our auditors specialize in the account model, CPI patterns, and ownership semantics that make Solana, CosmWasm, and NEAR programs vulnerable in ways Solidity auditors don't catch.
Why Rust Program Audits Require Specialized Expertise
Solana alone processes over 50 million transactions per day with billions in TVL. But Rust's memory safety doesn't mean your program is secure. The Solana account model (where programs don't own their data and accounts must be explicitly validated) creates entirely different vulnerability classes than the EVM.
Missing account validation, incorrect signer checks, CPI (Cross-Program Invocation) confusion, and PDA seed collisions have caused nine-figure losses. Anchor's constraints help, but they don't eliminate logic bugs. An auditor who only knows Solidity will miss these.
Our Methodology
Our Rust audit methodology addresses the unique security model of account-based blockchains.
Architecture & Account Mapping
We map every account, PDA derivation, and CPI call. Understand the trust model before reviewing code.
Automated Scanning
Sentinel runs Rust-specific static analysis, checking for common Solana pitfalls: missing owner checks, unchecked arithmetic, incorrect account deserialization.
Manual Program Review
Line-by-line review focused on account validation, signer authorization, CPI safety, and state transition correctness.
Invariant Testing
Custom test harnesses targeting program invariants. We simulate adversarial inputs, malicious accounts, and race conditions.
Report & Remediation
Severity-rated findings with Rust-specific fix recommendations. Re-audit of all patches included.
Vulnerability Classes We Target
These are the vulnerability patterns most relevant to this audit type: the ones that cause real losses.
Missing Account Validation
Programs that fail to verify account ownership, type, or initialization status. Attackers substitute malicious accounts to bypass logic.
CPI Confusion
Cross-Program Invocations to attacker-controlled programs that mimic expected interfaces. Signature and authority can be spoofed.
PDA Seed Collisions
Program Derived Addresses with insufficient or predictable seeds that allow attackers to derive conflicting accounts.
Signer Authorization Gaps
Missing or incorrect signer checks on privileged instructions: admin functions, fund transfers, state mutations.
Arithmetic Overflow
Rust's checked arithmetic in debug mode becomes unchecked in release. Programs that rely on debug-mode panics ship exploitable math.
Reinitialization Attacks
Accounts that can be reinitialized after creation, resetting state and allowing attackers to replay setup sequences.
