Customized solutions from a smart contract audit company.
The 4IRE team needs to understand the scope of your requirements and expectations from the provided smart contract audit services.
Your smart contract's inner logic and code undergo testing to ensure that all units work properly. This is achieved via unit testing.
A manual audit follows unit testing to determine the smart contract's immunity to a range of cyber threats and attacks.
An intermediate report is prepared based on the audit's unit testing and risk detection stages, together with improvement guidelines.
The final check is done after smart contract vulnerability corrections are introduced by in-house experts or 4IRE blockchain experts.

The process of delivering a smart contract security audit service depends on the complexity of your project, the number and type of checks included in the package, and the size of the audit team involved. On average, smart contract audits take from 24-48 hours to 1-2 weeks. Highly complex contracts, such as advanced DeFi protocols and cross-chain bridges, may take up to 4-8 weeks for a comprehensive check.
There is no one-size-fits-all price for smart contract audits — different companies charge custom prices for the combination of tools and depths of checks performed. The audit may cost anywhere from around $5,000 to over $15,000, depending on the number of code lines in your smart contract and its overall complexity.
You can access a variety of smart contract audit services at 4IRE, including code review audit, security audit, gas optimization, and functional audit, as well as formal verification, economic checks, penetration testing, upgradeability checks, third-party dependency audits, and standard compliance reviews.
We provide smart contract auditing services for the majority of popular, commonly used blockchain platforms, including Polygon, NEAR, Solana, and a variety of EVM-compatible blockchains (e.g., Ethereum). We can also perform a comprehensive dApp audit for decentralized apps built on any of these blockchains.
Define the audit's objectives and scope, choose the types of audits needed, and communicate these to the audit company. Supply comprehensive, detailed documentation, keep a clean and well-structured codebase, remove unused code, and run preparatory internal testing. Once the audit starts, freeze the codebase and hand over the final version of the contract for review.
4IRE combines automated and manual checks at various stages of contract auditing to ensure completeness and depth of security insights — giving clients access to checks of different levels of depth to keep their blockchain project under robust protection.
Manual audits give you access to human expertise and logic that AI and software tools can't yet match — identifying complex vulnerabilities, evaluating custom code logic, and reducing the false positives that are the greatest issue with automated auditing tools.
