What are Ethereum Smart Contracts?

Ethereum, created in 2013, is the world’s second-largest cryptocurrency by market cap and was designed specifically for creating smart contracts. To date, it is deemed as the most popular platform for doing so. Ethereum smart contracts are fragments of code that execute on the Ethereum blockchain. These contracts can execute transactions automatically if the specified conditions are met. Smart contracts define a set of rules and enforce them via the code, usually written in the Solidity programming language. Smart contracts are immutable on the blockchain, and their interactions are irreversible.

Ethereum smart contracts, however, are not completely immune to attacks. 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 Ethereum contracts can also be a reason for an exploit. The only way out is to get your projects audited!

Why Is It Important?

Smart contracts are immutable. Mistakes, once made, cannot be reverted. Take the wiser path to security audits and safeguard your and your users’ funds.

What Do We Offer?

An Ethereum contract audit with ImmuneBytes will make your projects tough for hackers to crack. We apply multiple security layers to enhance your contract’s longevity and performance in the market.

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.

FAQs

The world of Ethereum is enormous. And so are the questions associated with them. Here, we list the top 8 most frequently asked questions on the Ethereum Ecosystem.

A few of the most common and devastating vulnerabilities found in Ethereum 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.

Solidity and Vyper are the two programming languages supported by the Ethereum blockchain. Solidity is the most widely used smart contract development language. It is easy to use and resembles popular object-oriented programming languages. However, Vyper is another contract-oriented, pythonic programming language that targets the Ethereum Virtual Machine (EVM).

Some of the best practices for Ethereum 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.

There are several challenges associated with auditing Ethereum 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.

Ethereum smart contracts are permissionless and immutable. Thus, the applications are widespread. Ethereum contracts are being used to build DeFi protocols, DEXs, NFTs, native tokens, etc. The area of use includes but is not limited to healthcare, defence, real estate, gaming, banking and art.

Gas optimization is the process of making smart contract code less expensive to execute, which becomes increasingly important as projects scale. Techniques for gas optimization include:
  • Enabling Solidity compiler optimizer, which helps in minimizing the code.
  • Minimizing the amount of on-chain data required.
  • Freeing up unused storage space.

The time taken to complete an audit usually takes 5-7 days to process the initial audit report, depending upon the nature of the project, the technology stack used, the size of your codebase, the complexity of code, how tightly the code is integrated, the availability of auditors, etc. However, despite these factors, we take pride in meeting deadlines given by our clients and delivering satisfactory results.

The cost of an audit is variable depending on the complexity of the code, the programming language in which the smart contract is written and the lines of code.
