EvaCodes

Our overall experience with EvaCodes was outstanding. As an e-commerce agency, we needed a highly reliable subcontractor to handle complex blockchain integration without disrupting our standard development workflows, and EvaCodes filled that gap perfectly. From discovery through smart contract and API middleware deployment, their team demonstrated deep technical expertise and a proactive approach to security. What made them stand out was their ability to bridge Web3 engineering with traditional web development—something many blockchain developers struggle with. They provided our frontend engineers with exceptionally clean code and documentation, anticipated integration bottlenecks before they surfaced, and offered instant technical support. We launched the Web3 e-commerce solution for our enterprise client on time and within budget, and we're already planning our next project with them.

The engagement was consultative throughout. EvaCodes reviewed our platform architecture and flagged potential scalability concerns before they became real problems. They conducted a UX audit of the search and results flows, specifically examining how first-time users would navigate the product without guidance. They also consulted on our CMS setup for the content team and recommended performance optimizations for AI query response times. We received an architecture review document, a prioritized UX audit, CMS setup guidance, and a performance optimization report. Several of their UX recommendations made it directly into the product before launch: empty state handling, onboarding copy decisions, and how results display on mobile. Their architecture feedback helped our engineers avoid decisions that would have created technical debt down the line.

EvaCodes handled the blockchain side — smart contracts, wallet integrations, and everything related to Web3 functionality. We worked in parallel: our team focused on the core product, while they took care of the Web3 layer. We were able to deliver Web3 features as part of our projects without delays or extra overhead. It also allowed us to take on more complex client requests that included blockchain functionality. Overall, it helped us expand our capabilities and deliver projects more efficiently. We mostly communicated directly with the developer and the project manager. The team was great to work with — they picked things up quickly, stayed proactive, and even suggested their own ideas to improve the product. Overall, communication felt smooth and collaborative.

The work conducted by EvaCodes resulted in a secure and scalable integration of blockchain features within our product. They helped us support crypto-based transactions, automation of backend workflows, and minimized manual operations. We gained improved reliability, greater transparency in transaction handling, and a solid foundation to expand Web3 capabilities further.

Their clear communication, professionalism, and ability to adapt make them a true extension of our own team. We’re incredibly grateful for the partnership—thank you for everything you do!

I approached Eva Codes to create a modern Defi platform for transactions with crypto assets. The result was supposed to be a user-friendly application with wide functionality with the ability to buy digital assets, trade altcoins, NFT transactions, and so on. The work on the project took four months. The Eva Codes developers created the project concept in the form of a user-friendly application. Another significant decision of the developers was to create a blockchain network for creating individual blockchains and deploying smart contracts with high throughput and profitable commissions. Two Full-Stack developers, two QA specialists, a designer, a team lead, and a project manager have worked on the project. Collaboration with Eva Codes allowed us to successfully enter the market. The guys are extremely organized, always in touch, and their professionalism was felt from the very beginning of cooperation. The communication was mostly done via video link in Zoom.

I approached EvaCodes with a request to develop a blockchain-based electronic monetary system with which users can make various transactions with crypto and fiat pairs. The developers of EvaCodes have created a complete financial system with a modern design and a simple and intuitive interface. Additionally, work was done on the blockchain node monitoring dashboard, which displays node status and timer service settings. Today we continue the collaboration with the developers of EvaCodes. They are engaged in providing efficient operation of the application. A separate team of 8 specially trained and talented developers was assigned to the project. It involved one business analyst, two designers, one Full Stack developer, two blockchain developers, one QA, and a PM. The result has surpassed all expectations. We received an innovative blockchain-based money app with a rich user interface and functionality.Working with EvaCodes was a pleasure.

The challenge was to develop a DeFi crypto-wallet where users can have full control over their assets with the ability to store private keys themselves. We want to keep data about our financial transactions private from intermediaries. EvaCodes specialists immediately determined the scope of work. Professionalism and necessary knowledge allowed us to proceed with the development without delay. We worked with one analyst and manager who led this project, one QA and designer, and two developers. The team fulfilled the task 100%. In the near future, we plan to improve DeFido Coin and we hope very much that EvaCodes will suggest l us what features to add. The EvaCodes team did their job according to our agreements. There were no delays on their part. They were always in touch and responded promptly. Negotiations on the project were conducted mainly via Slack and Zoom. The project manager was very communicative and pleasant. Real professionals!

We approached EvaCodes to create a multifunctional cryptocurrency DeFi wallet. The blockchain development expert immediately offered us different solutions and showed us examples of ready-made projects they were doing for other customers. We agreed on all the details, and the guys started the development stage. All design ideas have been implemented. In addition, the developers have worked well on the security of the wallet. Three developers, one QA, UX/UI designer, and a project manager worked with us. We received a multifunctional service with a quick and easy registration procedure, easy balance checking, the ability to send and receive e-currency, instant withdrawal, transaction history, push notifications and chatbot, that responds to user requests with lightning speed. The guys were always in touch, promptly responded to calls and messages, always answered questions, and provided a report on the work done. We mainly used Trello and Slack for communication.

At the end of July 2022, we approached the EvaCodes team to perform a full audit of smart token contracts. The work was completed by mid-December. At the moment, the game is still at the stage of testing. It will be released in January 2023. EvaCodes specialists conducted a full audit of smart contracts with tokens and a decentralized system. Since a smart contract contains user funds, it was important to work on security. The experts worked on existing code errors and ensured maximum cybersecurity. The audit revealed a number of problems and errors , that were successfully eliminated. Smart contracts are protected. All parameters were transferred correctly. EvaCodes auditors ensured reliable cybersecurity for the entire system. We noted the high communication skills and professional approach to communication of the manager who managed this project.

We approached EvaCodes for services to enhance the functionality of DEX. We needed to add "claim form" support that would allow users to log in using their wallets and make their transactions with the tokens they received as rewards. The main condition was that DEX contract holders could make claims on the tokens. I found EvaCodes on the internet on one of the resources where employers leave reviews. EvaCodes auditors carried out full testing and provided an analysis of the system. The experts analyzed the updated contract containing addresses, types of claims, amounts, and dates of updates. The auditors did not find a high-severity issue but did find a medium-level vulnerability that was fixed by the re-audit, as well as 5 minor vulnerabilities. The full audit took four months. The main project manager, a team of three programmers, two auditors, one engineer, and one QA have worked with us. We communicated mainly through Slack messenger. For four months we had weekly meetings.

It was necessary to create an Internet platform for saling and exchanging cryptocurrency in a short period of time. Authorized users can communicate with each other in a special chat. EvaCodes was recommended to me by my friend, the founder of a financial company. In order to realize the project, the guys used the network blockchain, the data transfer protocol (client-server handshaking). Since security is an important priority for us, EvaCodes developers have through to the smallest detail of the system for protecting users' electronic money and personal data. They used a two-factor authentication system, an IP address tracking system, and verification. I am amazed that the guys from Eva Codes delved into my project and implemented it according to my words. They did 100% what I wanted and even better than I have imagine. Their manager was always in touch with me. Very pleasant to deal with and very professional.
