I always recommend HashEx to all ApeSwap Jungle family members because HashEx actually cares about your project and your code. They will work with you to improve it and will do it at a very reasonable rate. Other popular audit firms just want your money, HashEx wants you to be SAFU. If you are looking for an audit partner, this is the place to go!
HashEx is a great team of professionals in blockchain that could be given really tough tasks and be sure they will help. It’s extremelly rare that you can team up with an external team and get some load away from you main dev team, but with HashEx that’s exactly the case.
The is not the first time we worked with HashEx and definitely not the last time. The team is professional, precise in communication, and quick responding. Looking forward to work again.
The experience was amazing. It was a very easy process, the team was very cordial, and they explained everything to us in detail.

Overall, I loved the rapid delivery and professionalism from the HashEx team.

For me trust and security are of the utmost priority. This is why I decided to work with HashEx over the alternatives from word go. Dmitry and team are professional, punctual and hardworking. They care about our project and work with you rather than against you. What attracted me to HashEx was their superb locking facilities with their sub company CryptEx and the fact that they were able to highlight insecurities in Safemoon's code that even Certik did not. HashEx then supported Koda Cryptocurrency's move to V2 which was a huge success. Thank you HashEx and I am sure we will continue to work together.
HashEx has exceeded our expectations in every aspect. Undoubtedly, the team is highly professional. What surprised us is their strong emphasis on details. Whether it is the core function or the interactive experience, HashEx has made very detailed optimization suggestions. This makes us feel that the team is not merely doing a job, but is treating it as if it’s their own project and takes full responsibility for it.

It also helps if the project’s lp is locked, and the project’s team is known publicly or has passed a KYC by a tire one security company.How to read a HashEx audit report?
HashEx report consists of several blocks: aside from disclaimer, HashEx reviews submitted contracts, outlining the main issues in each contract. Auditors state the issue and present a short description with the potential danger of said issue. Note that there is a table of contents, in this case, audited contracts. It’s important to make sure that all the contracts have indeed been audited and that a client didn’t add new ones that haven’t been reviewed.What separates a HashEx audit from any other one?
HashEx team has a rich background in DeFi security. The company itself has over 4 years of experience in DeFi security and has performed over 500 audits. Our team of auditors has a vast library of known issues and thanks to manual reviews, they have the ability to find even minor errors. The reviews are performed first by an automated tool, then by two separate teams. This process is aimed at eliminating the possibility of missed vulnerabilities.Development
What types of contracts does HashEx develop?

Among successfully developed contracts there are fungible token contracts, NFT contracts, DAOs and Farms, Staking and Vesting contracts, and many others.What is the development process?
After the client approaches HashEx, we develop a vision of what the contract has to represent. We determine the type and language, the goals, and specific details. Then we develop the contract and test it. After that step, the client receives the finished product.What else does HashEx Develop?

How does HashEx test smart contracts?
As a part of the development process, HashEx always writes unit tests aiming to achieve 100% coverage.

HashEx also provides fuzzing services upon request.What testing tools does HashEx use?
HashEx tests smart contracts using several tools. Mostly, the developer team uses Hardhat, within which they apply a stack of ethers.js, waffle, and mocha. If further issues present themselves, and additional testing is required, other tools may be involved. If it’s imperative to test a contract, considering the real network data, the team does so using a mainnet fork. For Fuzzing HashEx testers use Echidna.
