Learn moreComprehensive and effective audits for smart contracts in the most popular programming language
request a quoteWith 2.5+ million smart contracts, Solidity is the most popular programming language for smart contracts. Ethereum, Tron, Polygon, BNB, Optimism, and 30 other chains/protocols on EVM use Solidity. Naturally, most crypto audits are also done in Solidity. Solidity accounts for every other smart contract audit ever done.
Critical vulnerabilities in Solidity code may prove costly after launch. Audit your smart contract code in the early stages of development to prevent catastrophic errors.
Auditing combines automatic scans with the line-to-line double review. Receive authoritative guidance on mitigating and preventing weaknesses in your Solidity code.
Fortify your smart contract written in Solidity. Let users notice your firm focus on security and ethics.
Hackers have exploited a lot of decentralized exchanges that were written with Solidity. Most DEXes have bugs. Outsmart the hackers by getting an audit.
Web3 is bringing a new innovative gaming experience to the public with NFTs. Secure your project effectively by auditing the smart contract behind your NFT and gaming project.
Wallets and bridges are faster routes for hackers to exploit funds. Therefore, get an audit to fix your critical vulnerabilities before the hackers do.
Solidity is a more versatile language that you can use to build other innovative projects. As you build every project with Solidity, smart contract audits are important to protect your project and secure your users.

Audit duration is agreed upon with the customer during the negotiation phase. We start the audit immediately after a client provides us with all required documentation.
Hacken started auditing projects in 2017. Since then, we have developed our audit quality control measures and methodology based on industry best practices.
You can meet Hacken members at crypto events and on social media.
During the negotiation stage, the cost of the audit is established. Without hidden fees and penalties.
Solidity audit reports are inegrated into CER.live, CoinGecko, and CoinMarketCap.
Hacken has a <1% incident rate among the audited projects and 0% of scam ventures.
You submit the required documentation and get the estimation of the audit scope, timeline, and price.
Once the initial testing is completed, our experts will provide you with a report that identifies the vulnerabilities detected and provides recommendations for managing them.
After you introduce fixes, our team will perform a remediation check to ensure that all changes are correct (1 check is included in the Solidity audit price).
Integrate Hacken audit into your website and see it displayed on CER.live, CMC, and CoinGecko. Your audit will be mentioned on the Hacken-owned and partner media.

“Solidity language has multiple use cases and it's ideally suitable for the growing DeFi ecosystem. There is a regular release of a new version of Solidity with embedded security fixes. However, it does not mean that the code remains free of bugs when new elements are added”
Hacken methodology is accepted by CoinGecko, CoinMarketCap, and Cer.live. We apply a four-stage approach to code review and analysis as it’s the most critical part. First, we run automatic tests to check all possible states of the contract and catch simple issues. Second, two separate auditors conduct independent line-to-line code reviews and analyses. Third, the lead auditor manually checks the parallel audits and performs an additional code review. Finally, auditors share the results and work out all disputable points. The smart contract audit by Hacken is so effective because it relies on several auditors to detect hidden weaknesses. We encourage our customers to go through our methodology before the audit and discuss any concerns and suggestions.
If your project meets Hacken’s partnership requirements, we will offer you an extended service package including marketing activities.

Solidity is the most popular programming language for writing smart contracts in Ethereum. More than 2.5 million smart contracts are written in Solidity.
Smart contracts written in solidity run on the Ethereum Virtual Machine (EVM). Ethereum, Tron, Polygon, BNB, Optimism, and 30 other chains and protocols, use this programming language. With Solidity, you can create contracts for voting, crowdfunding, blind auctions, and multi-signature wallets.
Of 4,813 all smart contract audits, 2,456 audits reviewed the Solidity code. In other words, Solidity accounts for every other crypto audit.
Solidity was designed for writing smart contracts. Solidity is so prevalent in crypto audits because it was specifically designed for smart contracts. Developers love Solidity because it integrates the most competitive features from C++, Python, and JavaScript.
The programming language is best suited for decentralized apps thanks to its flexibility. Solidity is statically-typed, allowing it to handle complex user inputs. Its object-orientedness gives it a focus on a contract. Solidity is a high-level language making it more human-like. The programming language also supports inheritance, libraries, and complex user-defined types.
The primary objective of Solidity is the automation of transactions on the blockchain. It is used to create smart contracts on Ethereum and other blockchains.
The total market cap of projects written in Solidity exceeds $1.8 trillion. The 24h trading volume is $338 billion. Contracts in Solidity are the most common targets for hacks, scams, and exploits. In 2020, 469 smart contracts in Solidity were hacked for $3 billion in damages.
A manual check of your code by seasoned security specialists eliminates security flaws in smart contracts that may have appeared as a result of adding new functionalities or modifying some features. Thus, Solidity smart contracts audit is the instrument enabling better functionality and improved security.
In Web 3.0, the common rule is that the more popular a technology, the greater the risks of being hacked. Since Solidity is the most popular programming language for smart contracts, it is only natural that hackers target it the most. Thirty-two chains and protocols use Solidity. Because of its popularity, more than half of all smart contract hacks and exploits are connected to Solidity.
Smart contract audits in Solidity make up 50 percent of all audits too. However, not all contracts have been audited and remain under higher threat. Thus, Solidity smart contracts audit is the way for projects to differentiate themselves from the myriad of Solidity-based projects for whom security is an empty word.
