What is a Rust Smart Contract Audit?

Rust is used to write smart contracts for ten chains, which include Solana, PolkaDOT, Near, Casper, and more. Code exploits that take place in Rust poseserious damage to users. If your Rust smart contracts have vulnerabilities, it can lead to a loss of funds, reputation, and time. With a total mcap of $200B and a daily trading volume of $43B, painful cyber attacks have become an integral part of Rust smart contracts. A Rust smart contract audit service is a line-by-line scanning of code to determine and eliminate vulnerabilities. Over the years, we have established a dedicated team of experts to offer top-notch security audits of contracts coded in Rust. At ImmuneBytes, our blockchain security experts identify code errors and potential risks in smart contracts coded in Rust and help fix them.

Rust Smart Contract Audit Stages

Our prolific team does its best to help you eliminate vulnerabilities and logic bugs in your Rust smart contracts. This process is a carefully performed code review. Our experts break this process into a few stages to ensure it is conducted smoothly. The steps are as follows:


1. Requirement Gathering

The first step involves analyzing the essential documents required for the audit process and analyzing them. These include documents like BRD, GitHub links, whitepapers, and all the other technical specifications. It assists the auditors in analyzing the intended function of the smart contract they are reviewing.


2. Automated Analysis and Unit Testing

The next phase involves the auditors writing custom unit test cases specific to the smart contract and performing test runs on those unit test cases, along with the test suite provided by the developers. Also, our security auditors deploy automated audit tools such as VRust to catch vulnerabilities on the surface level.


3.Manual Analysis

At ImmuneBytes, manual analysis is the most crucial step in the audit process. In this step, our team of auditors check the vulnerabilities in the code by scanning the whole code line-by-line. Our auditors examine the code for logical bugs and run your code against the fuzzing test suite. The auditors recommend addressing the found vulnerabilities and code optimization based on the performance.


4. Reporting

The last and final stage of the Solana security audit process can be classified into initial and final reporting. First, our auditors include their recommendations and the detected bugs in the initial reporting. Here, we classify them based on their severity level. After initial reporting, the developers refactor the code based on the recommendations from our auditors in the initial reporting and the final audit report is generated.

Rust Smart Contract Audit Structure

ImmuneBytes has a predefined structure for auditing a Rust 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 Rust 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

Rust 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 Is Rust Smart Contract Audit Important?

If you're wondering why you should go for Rust security audits, these are some benefits you get when you hand over your code to our reliable smart contract auditing company.

Why Choose Us?

Our team of auditors has the perfect expertise to discover every vulnerability in your contract and help you mitigate it. 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.

The world of Rust based contracts is enormous. And so are the questions associated with them. Here, we list the top 6 most frequently asked questions around a Rust Audit.

Rust achieves a stricter approach toward memory access and management. To know more about the differences between the vulnerabilities present in codes written in both of these languages, read our blog: here

  • When you are preparing for a product launch
  • Before an important listing
  • When you have noticed any malicious activity
  • After introducing major updates

Chains/protocols that rely on Rust include Nervos (CKB), Polkadot (DOT), OKC (OKT), Casper (CSPR), Solana (SOL), Secret (SCRT), Near Protocol (NEAR), Elrond (EGLD), Internet Computer (ICP), etc.

The most common virtual machines used with Rust are Low-level Virtual Machine (LLVM), Wasm, EVM, Wasmi, CKB-VM, Qtum x86, etc.

The duration of the audit that we perform depends on many factors, including the size and complexity of the project.

The cost of our audit process depends on many factors, like the code's complexity and the documentation you provide us. You can answer a few questions on our pricing page to get a rough idea of the audit cost we will perform for you.
