Code Audits
Rust Smart Contract Audit
Avoid costly exploits. Our Rust smart contract audit is a senior-led, attacker-minded service that mitigates exploit risks. We review your system end-to-end, test critical paths under pressure, and deliver a clear, actionable report your team can use today with issues, severity, and fixes. This includes Solana smart contract audits, for teams on Solana.

Our Rust auditors combine automated analysis with deep manual review, threat modeling, and security best practices. Whatever you are building, our Rust & Solana audits help you ship efficient, resilient, mainnet-ready code.
What is a Rust Smart Contract Audit?
A Rust smart contract audit is an in-depth security review of your on-chain Rust program that identifies vulnerabilities, logic errors, unsafe assumptions, and performance traps before deployment. On-chain code is difficult or risky to change after launch, especially if upgradeability is disabled or tightly controlled, and so any flaw in your code can lock funds, corrupt state, or break core invariants. As a Rust smart contract audit company, we go beyond automated checks with line-by-line manual review, realistic attack-path modeling, and validation of critical invariants via property tests and fuzz testing.
Why does a Rust Smart Contract Audit Matter?
Rust removes many memory-safety bugs, but it doesn’t prevent logic flaws, incorrect state transitions, or brittle upgrade paths. As systems compose, one bad interaction can ripple across contracts. A third-party Rust smart contract audit surfaces these risks before mainnet, builds confidence with users and investors, shortens recovery when issues appear, and protects your brand at launch.If you also need operational coverage (keys, multisigs, processes), add our OpSec review to the scope so you get complete 360º security.
Common Vulnerabilities Found in Rust Audits
Serialization/Encoding drift
Changing struct fields, enum order, or defaults breaks Borsh/SCALE decoding. Old state loads wrong, flags flip, and balances or permissions get corrupted after upgrades.
Storage layout changes
Deserialization maps fields incorrectly, leading to corrupted account state or mismatched permissions.
Integer math and units
Mixed u64/u128, wrong fixed-point scale, or silent wrapping in release builds (Rust u64 overflows wrap unless checked) skew fees, supplies, and accounting. Small rounding bugs compound across many calls.
Cross-program call order
Common in Solana security audits. If state updates happen after cross-program invocations (CPIs), external effects may occur before invariants are enforced. While Solana’s runtime prevents classic reentrancy, delayed state updates still create inconsistent accounting and unexpected behaviors.
Web3 projects have lost millions to exploits. These are patterns we repeatedly uncover in Rust smart contract audits. Each looks small on paper and expensive in production.
Our Smart Contract Audit Process
Scoping and Planning
We define the full Rust smart contract audit scope, list program modules, dependencies, and critical entry points, and align on objectives and timelines.
Architecture Review
We examine architecture and integrations, map attack surfaces, and flag systemic risks in account and state design.
Code Review
We perform a line-by-line Rust smart contract security review to detect vulnerabilities, inefficiencies, and deviations from best practices.
Testing
We run static analysis, write property tests, apply focused fuzzing, and use fork/devnet simulations. We build proofs of concept to reproduce issues and measure real impact.
Reporting & Recommendations
You receive a full audit report with prioritized findings and step-by-step remediation guidance.
Verification
After fixes, we retest and confirm that issues are resolved before mainnet deployment.
Our Rust Audit Service
Our Rust audit service is for teams preparing to launch or deploy a new on-chain feature who want to reduce exploit risk before users touch it. Audit when you’re ready to freeze the code and share a locked commit. During the audit, hold all feature changes and refactors. After the report, the only edits allowed are the fixes we recommend.
We tailor each smart contract audit to your protocol’s architecture, ecosystem, and use case.
Whether your project runs on:
We account for unique language risks, dependency interactions, and upgradeability concerns. Our process is designed not just to identify problems but to provide practical, high-impact recommendations that make your contracts more secure, efficient, and resilient.
Aftercare & Verification
We review your fixes, re-test only those changes, and update severities. Once verified, you’re clear to ship. Any change beyond the audited fixes is new scope and needs a fresh review.
Deliverables You Can Expect
For a Rust smart contract audit, you receive engineer-ready documentation with severity-ranked findings, minimal-change remediation guidance, and clear notes. See our case studies for example reports.
Post-audit support is included
to help your team implement fixes and validate their effectiveness.

Frequent answers and questions
Check out the Rust Smart Contract Audit F.A.Q.
What does a Rust audit cover?
Logic and economic correctness, signer/ownership validation, state and storage handling, upgrade paths, error handling, and integration risks.
Do you audit framework-based programs?
Yes. We audit raw Rust programs and framework-based contracts, highlighting risks introduced by abstraction and macros.
Which chains do you support for Rust audits?
We mainly do Solana audits, but we also audit contracts on NEAR, Polkadot, and other Rust-based ecosystems.
When should we schedule an audit?
Before mainnet deployment, after major upgrades, or whenever new instructions, accounts, or integrations are added.
Can an audit improve performance?
Yes. We call out inefficient patterns in storage, execution, or cross-program interactions that can be optimized without sacrificing security.
