Optimism

OP Mainnet (Optimism) is a quick, stable, and scalable L2 blockchain developed by OP Labs and runs on its software called the OP Stack. OP Mainnet is a Layer 2 network that operates on top of Ethereum's architecture, acting as a minimal extension of the main Ethereum layer. It allows developers and crypto users to enjoy quick transactions at low fees while maintaining the security of Ethereum's architecture.

The audit process

What is a smart contract audit?

A smart contract security audit is a comprehensive process where one or more security researchers review a smart contract or protocol codebase to find, report, and mitigate critical security vulnerabilities that will disrupt your services.

1

Setup timelines and onboarding
Our engineers will estimate the timeline based on codebase complexity and size and open a line of communication.

2

Lock commit hash & start date
We agree on a start date and a commit hash to base our audit. To get the most out of a security audit, we recommend that this commit hash not change during the audit.

3

Audit begins
Our engineers will spend the allotted time on your contracts. We strongly recommend keeping an open communication channel between us and your engineers during this process.

4

Initial audit report
The initial report will explain each issue categorized as High, Medium, Low or Informational. We will set up a call with your engineers to ask questions about the findings.

5

Mitigation
Your engineers will have a chance to mitigate the findings using the recommendations in the report.

6

Final audit report
Once the mitigations have been applied, our engineers will check them and amend the issues on the report as "Acknowledged" or "Resolved" with any necessary extra information.

protocols.

An Optimism smart contract audit involves a detailed analysis of the contract's code performed by one or multiple smart contract security researchers to identify security issues, vulnerabilities, and inefficient code and determine ways to mitigate the findings. The audit process is a crucial part of enhancing the security and reliability of blockchain applications, Optimism protocols, and their users. Security isn't a single sprint effort but a continuous improvement journey. Cyfrin is committed to giving protocols built on Optimism all the tools they need to walk it.
Testimonials

We’re making protocols safer— but don’t just take our word for it

Here's a sneak peek into our previous smart contract audits and how we've helped secure tens of billions of dollars across blockchains and protocols.

It was a pleasure to work with the Cyfrin team. Their approach to security and meticulous testing is exceptionally thorough. Additionally, their intimate knowledge of the Chainlink protocol made them particularly useful for our audit.
