What are Optimism Smart Contracts?

Optimism is an L2 blockchain built for Ethereum developers for scaling purposes. Moreover, Optimism is comparatively cheaper and faster than Ethereum. Smart contracts on the Optimism chain can be complex as they act as a bridge between L1 and L2 chains to move money.

We have a proficient panel of auditors with expertise in auditing codes across every major protocol and programming language like Solidity, Go, JavaScript, C++, and more. With our audit process, you can simply develop and deploy your Optimism contracts without losing access to them to hackers!

Why Is It Important?

As millions of dollars are at stake, thus, it is important to free the code from all the vulnerabilities before making it go live on the mainnet.


No More Loss of Funds

Vulnerabilities in Optimism smart contracts can result in massive losses of funds, both yours and your clients. With ImmuneBytes audits, you can rest assured that your assets are safe on the blockchain.


Code Optimization

Gas plays an important role in Optimism smart contracts. It becomes crucial to optimize the usage of gas in your source code. We not only reveal bugs but also offer recommendations for improving gas usage.


Build Trust

The stamp of an audit on your smart contracts attracts potential investors and clients. Smart contracts audited by ImmuneBytes have a lesser chance of getting exploited.

Why Should You Undergo A Optimism Smart Contract Audit?

Optimism is new and exciting, and crypto enthusiasts love it because it brings a newness to the table. It makes Ethereum more efficient by implementing Optimistic Rollups, which allows it to process transactions much faster. OVM is a new virtual machine, and its understanding of it is not as prevalent in the industry. Thus, it becomes imperative to secure the systems being deployed on it. Our security auditors are well aware of the working of OVM and cross-messaging applications and provide audits based on their industry experience. We recommend undergoing a security audit before deployment!

What Do We Offer?

We are a crew of experienced auditors who have been in this industry for quite some time. We have evolved as one of the leading token smart contract audit companies. We do our best to help our clients eliminate the fear of losing access to their funds or applications.

Extensive Audit Report

Our audit reports are comprehensive and document every measure taken during the audit process. We classify the vulnerabilities according to their severity levels and offer remediations and code optimizations.

Check For 100+ Vulnerabilities

We analyze a smart contract for over a hundred vulnerabilities. These include bugs that have been exploited and others that could be exploited in the future.

Smart Contract Fuzzing

We fuzz-test your smart contracts as an additional measure. Fuzzing a smart contract ensures that it will not behave unexpectedly against any given input, minimizing the risk of hacks.

Post Refactor Reaudits

Not just once, we audit your code twice! Once your developers review our audit report and make the recommended fixes, we again analyze your contract and prepare the final audit report.

Security Test Cases

Our auditors use frameworks like Foundry, HardHat and Truffle to write unit test cases other than the developers provided. We ensure to traverse every possible branch of execution in the source code.

Quick Turnaround Time

A dedicated team of auditors is assigned to your project, who usually take 3-10 days to complete an audit, depending on the code size. We are result-oriented and understand the gravity of deadlines.

The world of Optimism is enormous. And so are the questions associated with them. Here, we list the top 5 most frequently asked questions on the Optimism Ecosystem.

A few of the most common and devastating vulnerabilities in Optimism contracts include re-entrancy, front-running, integer overflow and underflow, simple logic error, block gas limit vulnerability, default visibility, timestamp dependence, denial of services attack and tx.origin authentication attacks.

Optimistic Rollups are one of the ways to make Ethereum more efficient, i.e. faster and cheaper. They are often termed L2 solutions. Optimistic Rollups don't verify the new state each time.They lock it up for a week, called a 'challenge window', and anyone can submit the mathematical proof during this week if they find a faulty state update. If not, the state is pushed to finality.

TSome of the best practices for Optimism smart contract development are ensuring careful rollouts, minimizing the contracts' complexity, staying up to date with new releases and bug fixes, modularity in smart contracts and developing rigid and upgradeable contracts.

Optimism smart contracts are used for moving money across L1 and L2 blockchains. Optimism helps Ethereum users to save up on gas fees by rolling up batches of transactions using Optimistic Rollups.

There are several challenges associated with auditing Optimism contracts, such as the continuous updates on the blockchain, frequent releases of Solidity versions, and the need for more reliable resources for auditing. Nevertheless, our auditors are skilled in their niche and are equipped with recent updates
