Solidity Smart Contract Audits
The EVM powers the majority of DeFi value. Our Solidity audits combine manual line-by-line review with automated analysis to find the vulnerabilities that tools miss: business logic flaws, access control gaps, and economic attack vectors.
Why Solidity Audits Matter
Solidity contracts hold over $85 billion in TVL across Ethereum and EVM-compatible chains. The language's design (with its reentrancy-prone external calls, integer handling, and storage layout complexity) creates vulnerability classes that don't exist in other languages. Between 2020 and 2025, Solidity-based protocols accounted for the majority of DeFi exploit losses.
The risk isn't theoretical. Most contracts are immutable once deployed. A single missed vulnerability in a function that handles deposits, withdrawals, or governance can drain an entire protocol in a single transaction. Audits aren't a checkbox. They're the last line of defense before code becomes irreversible.
Our Methodology
Our Solidity audit process is built around finding the vulnerabilities that automated tools consistently miss.
Codebase Ingestion & Scoping
We map the contract architecture, identify trust boundaries, external dependencies, and upgrade mechanisms. Scope is agreed with your team before review begins.
Automated Analysis (Sentinel)
Our AI engine runs static analysis (Slither, custom detectors), symbolic execution, and pattern matching across the full codebase. Known vulnerability classes are flagged automatically. Sentinel catches ~90% of issues.
Manual Line-by-Line Review
Every function reviewed by an experienced auditor. Focus on business logic correctness, access control, state management, and economic attack vectors that tools cannot detect.
Fuzzing & Invariant Testing
Foundry-based property testing targeting protocol invariants. We write custom fuzz campaigns for your specific logic, not generic templates.
Findings Review & Remediation
Severity-rated findings delivered with root cause analysis and concrete fix recommendations. We re-audit all patches to confirm correct remediation.
Vulnerability Classes We Target
These are the vulnerability patterns most relevant to this audit type: the ones that cause real losses.
Reentrancy
External calls before state updates allow attackers to recursively drain funds. Responsible for some of the largest exploits in DeFi history.
Access Control Flaws
Missing or incorrect authorization checks on privileged functions: admin operations, upgrades, emergency withdrawals.
Oracle Manipulation
Price feed dependencies that can be manipulated via flash loans or low-liquidity pool attacks to trigger incorrect valuations.
Integer Overflow & Precision Loss
Arithmetic errors in token calculations, fee distributions, and share pricing that compound into exploitable rounding errors.
Storage Collision in Proxies
Upgradeable proxy patterns with misaligned storage layouts can corrupt state variables across implementation upgrades.
Front-Running & MEV
Transaction ordering dependencies that allow miners or searchers to extract value by sandwiching user transactions.
