Smart Contract Audit

Worried about the security and reliability of your smart contract? We’ve got you covered.

In our Smart Contract Audit, our team will meticulously review the code line-by-line to uncover any vulnerabilities or potential issues shielding your project from security breaches and financial risks.

What is a Smart Contract Audit?

A smart contract audit is a comprehensive and systematic review of a smart contract’s code, functionality, and security to identify and mitigate potential vulnerabilities, bugs or errors.

The audit should take place ahead of deployment - this is crucial as once the smart contract is deployed no changes can be made. By auditing the contract ahead of deployment we can work with you to address any vulnerabilities or issues and avoid financial risk.

Why should I get a Smart Contract Audit?


Mitigate Risk

An audit helps to identify and mitigate risks early in the development process. Addressing vulnerabilities before deployment is far more cost-effective than dealing with the aftermath of a security breach


Functionality Check

Audits not only focus on security but also check if the smart contract operates as intended. Ensuring the contract works correctly helps maintain a smooth user experience and minimises errors.


User Trust

Users of your smart contract need to trust that their transactions and assets are safe. An audit is a way to demonstrate your commitment to their security.

In 2023, the total loss from crypto hacks amounted to approximately $2 billion across various cyberattacks and thefts.

Smart Contract Audit Process

Initial Consultation and Preparation
Engage in a free consultation to discuss the audit scope and prepare by gathering all relevant documentation, including the smart contract's code and technical specifications.
Code Review and Testing
Perform a detailed, line-by-line code review to check for errors and vulnerabilities, followed by functional testing to ensure the contract operates as intended under various conditions.
Security Assessment
Assess the contract’s security measures and evaluate its resilience to security threats and attacks.
Reporting and Discussion
Report findings, categorizing vulnerabilities, bugs, or issues by severity, and discuss these findings, explaining recommendations and addressing any queries or concerns.
Remediation and Finalization
Remediate identified vulnerabilities and issues, re-evaluate to ensure they have been effectively addressed, and then finalize the process with a report certifying that the contract is ready for deployment.
