How do we establish the price of a smart contract audit?

We provide tailored quotes based on your unique needs and offer continuous communications during the audit to reduce idle development time. Audit pricing is determined based on the following factors, and more:

Code complexity

The intricacy of the smart contract logic.

Code size

Number of lines of code and contracts involved.

Project timeline

Urgency and desired delivery timelines.

Benefits of our audit process

At Nethermind, we adopt an agile approach, meaning our team can deliver value quickly, and with complete process transparency. You'll be invited to participate actively throughout the auditing process. We maintain regular communication with our clients through scheduled sync calls, providing progress updates, and descriptions of discovered bugs.

Reduced idle time

Rather than waiting for the final audit report, the client receives partial reports throughout the process, enabling code corrections while the audit is still in progress.

Transparency

Regular sync calls provide clients with full visibility into our auditing process. Our clients deserve to know how the audit is progressing every step of the way. No black boxes.

Leveraging in-house expertise

Our auditors will work in tandem with our engineers to detail your protocol's vulnerabilities and to propose a robust resolution.

Close client collaboration

We unlock time efficiencies while conducting the audit. A collaborative client relationship allows us to rapidly evaluate and understand the smart contracts and increases the quality of the audit report.
