Smart Contract Auditing

OCamlPro offers specialized smart contract audit services combining manual code review with formal verification techniques to identify vulnerabilities and ensure contract correctness before deployment. As an active member of the FreeTON/EverScale Formal Verification Sub-Governance, the company has proven expertise in auditing Solidity smart contracts, winning first prize multiple times in audit contests organized by the EverScale Network.

Audit Methodology

The smart contract audit process follows a rigorous multi-stage approach:

Pre-Formal Specification: Writing comprehensive specifications describing the overall behavior of the smart contract and the individual behavior of each function and component. This creates a clear reference for expected functionality.

Manual Code Review: Careful reading of contract code to identify semantic bugs, architectural flaws, and deviations from best practices. This includes checking for common vulnerabilities like reentrancy, integer overflow/underflow, access control issues, and gas optimization problems.

Automated Analysis: Deployment of specialized tooling to analyze smart contract code, finding bugs through static analysis, symbolic execution, and pattern matching against known vulnerability patterns.

Formal Verification: For critical contracts, mathematical proof that the code implements its specification correctly, using tools like the Coq proof assistant and Why3 Platform with Alt-Ergo theorem prover.

Blockchain Expertise

OCamlPro's audit team has deep experience across multiple smart contract platforms:

EverScale/FreeTON: Extensive Solidity audit experience, including developing formalization of the EverScale Virtual Machine for formal verification of Solidity contracts.

Tezos: Created decompiler tools between Michelson and Liquidity to ease auditing of Michelson smart contracts, leveraging their deep involvement in Tezos ecosystem development.

Ethereum: Developed Solidity parser in OCaml with Menhir, enabling sophisticated static analysis and cross-chain smart contract portability.

Deliverables

Comprehensive audit reports detailing all identified vulnerabilities categorized by severity (critical, high, medium, low), specific recommendations for fixes with code examples, formal specification documents, and post-fix verification to confirm vulnerabilities are properly addressed. For high-assurance requirements, formal proofs of critical properties like fund safety and access control correctness.

Target Clients

DeFi protocols requiring security audits before mainnet launch, DAOs managing significant treasury funds, NFT platforms with complex minting and royalty logic, cross-chain bridges handling asset transfers, and any blockchain project where smart contract failure would result in significant financial or reputational damage.
