Maximum security professional audit of smart contracts

Smart contract auditing is a tool to ensure the security and reliability of blockchain projects. We provide an in-depth and professional code analysis service to protect your business and clients from potential threats and errors. FreeBlock experts perform smart contract checks, identify vulnerabilities, and provide recommendations for fixing them.

Our services

Auditing smart contracts of all types

We review all categories of contracts: for ERC-20, ERC-721, and ERC-1155 tokens, decentralized exchanges (DEX), liquidity pools, NFT marketplaces, and decentralized autonomous organizations (DAO). We conduct smart contract audits for crowdfunding, staking contracts, voting contracts, oracles, access control management contracts, and digital asset storage.

In-depth analysis and verification of smart contracts

We analyze and test code using automated tools and manual assessment methods. We identify potential smart contract bugs that could cause fund leakage or disrupt project operations. We use modern blockchain audit methodologies. We perform detailed code analysis using Mythril and Slither.

Comprehensive security assurance

We audit code, analyze cryptographic methods, and verify the structure and logic of algorithms. We use automated scanners and dynamic analysis to find potential weak points. We detect issues early in development. As part of smart contract testing, we use Echidna and Manticore to model attacks and perform stress testing.

Verification of correct condition execution

We identify smart contract errors that may lead to unintended consequences after launch. We review execution conditions, test logic, and verify compliance with business rules.

Detection and removal of scam scenarios

We pay special attention to checking smart contracts for scam and fraud schemes. We use specialized tools and methodologies for automated and manual assessment of suspicious scenarios. We provide confirmation of smart contract security. As part of a comprehensive analysis, we check smart contracts for scams online.

Formal verification

We apply formal verification methods for smart contracts with mathematical proofs of correct execution of the conditions embedded in the code. In blockchain audits, we use the K Framework and Coq to ensure complete security and eliminate errors in smart contracts.

Using up-to-date automated tools

We actively integrate automated analysis and testing systems into our workflow. This approach makes it possible to detect smart contract bugs quickly and accurately. These tools thoroughly check smart contracts for scams and find vulnerabilities that are difficult to spot. A proactive approach ensures smart contract security at a high level and reduces risks to zero.
