What are Arbitrum Smart Contracts?

Arbitrum layer two solutions are the first original second layer Blockchain to launch for Ethereum. Arbitrum utilizes the optimistic rollup that permits the scaling of Ethereum smart contracts by communicating between smart contracts on Ethereum and those on Arbitrum L2 blockchains.

Smart contracts on the Arbitrum blockchain are written in the Solidity language. There is always a chance of your project getting drained due to the presence of a small bug that was overlooked during development. Vulnerabilities such as re-entrancy, flash loans, front-running, destructive external calls, etc., have resulted in hacks worth millions of dollars. Using an older version of the Solidity language in Arbitrum contracts can also be a reason for an exploit. The only way out is to get your projects audited!

Why Is It Important?

Wondering why it is important to get an audit? Well, wonder no more! Here are several reasons, more than enough of why you should get an audit before going live.


No More Loss of Funds

Vulnerabilities in Arbitrum 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 Arbitrum 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 An Arbitrum Smart Contract Audit?

Arbitrum, being the most popular Optimistic Rollup for Ethereum, garners enough attention from hackers to get exploited if a weakness is found in your project. Smart contract vulnerabilities allow hackers to get a backdoor entry into your system and destroy its working. As the Arbitrum ecosystem grows, so does the number of applications built on it. Thus, a security audit is crucial to make your project stand out and not get exploited.

What Do We Offer?

Our auditors are skilled in their niche and audit the code with a real-world perspective. Being a team of Web3 enthusiasts, we understand the risks and make sure to eradicate any potential threat.

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

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

Some of the best practices for Arbitrum 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.

One of the biggest advantages of building on Arbitrum is that you can run unmodified Ethereum Virtual Machine Contracts and transactions on a second layer. Arbitrum's gas fees are also lower than Ethereum's.

Absolutely. You can have your team of testers do the due diligence. However, getting a third party to audit your smart contracts is always recommended, as there is no developer bias. You also get an outer perspective on the performance of your application.

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