The Process

About Our Work

We ensure your smart contract goes through all the stages from manual code review till automated testing before we generate the initial audit report. Once your team updates the code, we do a thorough scrutiny of the smart contract to provide you with the Final Audit report.
You can know more about each stage of our audit process here.

Frequently Asked Questions

What is a Smart Contract Audit?
Smart Contract Audit is a comprehensive process to scrutinize a smart contract’s code that is used to interact with a cryptocurrency or blockchain. This process is carried out to discover errors, issues & security vulnerabilities in the code in order to rectify & fix them. It secures the code from potential future bugs.
Who needs a Smart Contract Audit?
Smart Contract Audit is for everyone who is dealing with smart contracts, either you have an ICO, STO, fintech, Games or any Dapp solution based on Smart Contract you should go for third party Audit
What is the time scale for an audit to complete?
The time span of an audit depends on the code size & the complexity of the project. A standard token (ERC20 & other ERC standards) can be audited within a week, on the other hand, complex DeFi projects, Blockchain wallets/dApps may stretch around a couple of weeks to a month.
What Audit process do we follow?
We scan for vulnerabilities present in the system by running various test cases. We also conduct manual testing to verify the code for its intended use case. Apart from this, we also leverage in-house & open source security tools as per the smart contract’s framework.
What are the differentiating grounds for automated audit & manual audit?
Manual Audit is performed by our in-house team of skilled code auditors to testify the correct implementations of its specifications.

But “To Err Is Human”, hence we also take advantage of various smart contract code testing tools. These tools work on methodical principles of mathematics, hence prove the implementation of contracts based on their specification.
How much does a smart contract audit cost?
Our price varies from one smart contract to another. It depends on the complexity of functionalities and the lines of code in the smart-contract. We follow an intensive audit process by keeping the cost minimal to ensure maximum security.
