Solidity Smart Contract Audit
With impeccable command over solidity language, our expert auditors make your smart contracts free from vulnerabilities and bugs.
What is a Solidity Smart Contract Audit?
Solidity is an object-oriented, high-level language for implementing smart contracts. Smart contracts are programs that govern accounts' behaviour withinthe Ethereum state. Solidity is a curly-bracket language that targets the Ethereum Virtual Machine (EVM). With over 2.5M smart contracts, Solidity is the most commonly used programing language for smart contracts. It is a popular choice for blockchains/protocols like Ethereum, Optimism, Tron, BNB, Polygon, and 30 others. Naturally, most crypto audits we conduct are also done in Solidity.
Solidity Smart Contract Audit Stages
We have an experienced panel of Solidity smart counteract auditors with expertise in determining and eliminating vulnerabilities in the code within a few moments. We follow a fixed procedure for our audit process.
1. Pre-Requisites
Firstly, we garner information that is required for the audit process. We review essential documents like BRD, GitHub links, whitepapers, and all the other technical specifications. It gives a clear picture to our auditors on whether the intended function of the smart contract they are reviewing is working properly.
2. Unit Testing
Developers write unit cases; the next step involves performing the test runs on those unit cases. This helps us understand whether the code is functioning as intended. We use many auditing tools to ensure that the audit process covers all the risks associated with the unit cases.
3. Manual Auditing
We scrutinize every code line-by-line to find all the vulnerabilities in them. It helps us trace even the minutest bug that we help our clients eliminate by giving them recommendations to fix them. With the help of tools like Mythril, slither, mythx, etc., our auditors proceed with automated auditing.
4. Reporting
The final stage for auditing Solidity smart contracts is reporting. This stage can be further divided into initial and final reporting. First, our auditors include their recommendations and the detected bugs in the initial reporting. After initial reporting, the developers refactor the code based on the recommendations from our auditors in the initial reporting.

Solidity Smart Contract Audit Structure
ImmuneBytes has a predefined structure for auditing a Solidity smart contract, and we intend to follow it unless there’s any custom requirement. The structure is simple, and it helps our clients to understand our audit methodology better!
Audit Overview
An initial overview of the smart contracts under examination to get a gist of what the system intends to do and what type of application the client wants to build.
Known Vulnerability Description
This section contains information about the known vulnerabilities of Solidity smart contracts and the vulnerabilities that will be tested during the audit process.
Critical Contract Vulnerabilities
These are the bugs that, when exploited, result in fund losses and are crucial to maintaining the integrity of the client.
High-grade Contract Vulnerabilities
Solidity smart contracts often have bugs in them which can conflict with the business logic of the application and hinder the intended use case.
Medium Contract Vulnerabilities
Medium-level bugs are those which can damage the system but have certain limitations to them. These might tamper with the performance of the contract.
Low-grade Contract Vulnerabilities
Low-grade vulnerabilities are usually informational and must be fixed for the smart contract to perform better and faster.
Gas Optimization Suggestions
Gas plays an important role in blockchain transactions, so optimizing your contracts for gas is an essential part of the audit process.
Audit Summary
An audit summary is given to the client once the audit is over, detailing each vulnerability found along with the recommendations to fix it.
Why Solidity Smart Contract Audit is Important?
We have the upper hand in finding vulnerabilities in the code and know how to eradicate them for the smooth functioning of the solidity smart contract. These are the following benefits of getting your Solidity smart contracts audited from us.
It prevents exploits caused by security vulnerabilities
It helps in improving performance by revealing scopes of code optimization
It makes projects more trustworthy for prospective investors and users
It helps in saving on gas expenses
Why Choose Us?
We have highly skilled auditors who have an industry experience of many years. We do our best to help our clients eliminate the fear of losing access to their funds or applications. These are some of the highlights that allow us to distinguish ourselves from the crowd.
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.
