Standing at the helm of blockchain technology, top smart contract development companies specialize in building secure, efficient, and highly accurate smart contracts - digital contracts stored on a blockchain that outline the terms and conditions of an agreement between two parties. They employ teams of blockchain developers, engineers, and cybersecurity experts who can design and deploy smart contracts on various blockchain platforms, like Ethereum, IBM, Hyperledger, and more. Businesses can leverage their cutting-edge solutions to bolster the security and transparency of transactions, and streamline and automate complex business processes, from supply chain management to finance, healthcare, or retail. Compare prospective partners by client reviews, pricing, size, and more to find the most suitable one for your project.
Organic rankings are determined by five factors: top services, reviews, portfolio, awards/press, and team expertise. Sponsored listings pay for a placement that appears above organic positions. Sponsorship does not affect star ratings or review content - read more on our methodology page.

We tasked Rocketech with building a roulette system that could live-stream game results directly from an offline casino. There were 3 iterations of the project. The solution has mobile and web versions, supports more than 30 integrations, and provides different monetization channels.Overall, we saved 9 times the budget, while getting high-quality services. The platform handles more than 20K players worldwide and 2 million bets a year. Weve been successful on the market for more than 5 years.

RichestSoft Reviews & Testimonials

Web Development Review from Lathan Ashton
RichestSoft was tasked with taking our existing templates, upgrading them to the latest version of our CMS, and deploying them to a staging environment. They also updated the designs for all subsections of the site. The site is fairly generic, consisting of static pages with links from the homepage to product descriptions, case studies, and more. Our team can easily log into the CMS and update case studies without needing a web developer, which has been a huge advantage. Our primary concern was the seamless conversion of our old templates, and RichestSoft handled this flawlessly. They even suggested ideas like making the site multilingual, though we only needed an English version, so it wasn’t necessary in our case.

Web Development Review from Robbie Hart
The website now has a more modern and appealing feel, and we've noticed an increase in the number of visitors since working with RichestSoft. They effectively leverage their technologies, and their communication and timeliness have been satisfactory throughout the project. Our business is centered around land development and industrial projects, supported by a team of IT professionals that manage the technology driving our operations. Our mission is to provide quality and satisfaction by utilizing our knowledge, experience, and ambition to meet and exceed our clients' expectations.

Web Development Review from James Shehan
RichestSoft consistently delivered on a complex and demanding project, handling all tasks with efficiency. Whenever any bugs or issues surfaced on the site, they promptly resolved them. While there have been occasional communication challenges, none of these have affected the high-quality and cost-effective service they provide.

UASOFTDEV Reviews & Testimonials

Software Development Review from Slava Kostiuk
We initially approached UASOFTDEV with a relatively straightforward request: a WordPress website and a Senior React/Node/Python Developer for backend and API development. What impressed us immediately was how quickly they understood our needs and delivered relevant candidates. We received the first 5 candidates within 60 hours, exactly as promised. The developers were skilled, experienced, and cost-efficient, so we decided to continue working with UASOFTDEV. Later, we returned with a much more complex project: an already-live AI beauty ecosystem combining a Smart Mirror, mobile app, AI skin analyzer, and AR makeup. This required a Senior Flutter Engineer who could join an existing team and work with Flutter, Banuba SDK, Java/native technologies, and a production environment. UASOFTDEV matched us with a senior Flutter engineer within 60 hours. He integrated quickly into our existing team and provided the 24/7 production support we needed. During the 5.5-month engagement, we delivered 10+ major features, shipped 15+ releases across 3 product environments, and launched 2 premium subscription features. What we valued most was the consistency of their approach. Production issues and new feature requests were handled quickly, communication was personal and responsive, and the team remained highly engaged throughout both projects. The fact that we came back to UASOFTDEV with a second, significantly more technically demanding AI/AR project is probably the strongest proof of our satisfaction. They successfully scaled from a simple staffing request to supporting a complex live product without losing the same level of responsiveness, quality, and personal attention.

DevOps Consulting Review from Khrystyna Sliana
We hired a DevOps engineer from UASOFTDEV to handle a multi-entity AWS infrastructure split. The project was completed on schedule, with zero downtime and great attention to security and data integrity. Recommended.

Dedicated Team Augmentation Review from Leonid Viktorov
I am the CEO of Biz Adviser, a business consulting company. We work with companies on strategic business initiatives, digital transformation, and improving business performance. We partnered with UASOFTDEV when we urgently needed additional engineering capacity. I was looking for proven senior developers and did not have time to spend weeks sourcing candidates and conducting multiple interviews. UASOFTDEV offered to provide vetted Ukrainian developers within 60 hours, which was exactly what we needed. The team provided senior engineers with strong technical expertise and excellent communication skills. We worked with developers across PHP, Node.js, Python, and React, depending on the project requirements. They were reliable, proactive, and able to understand not only the technical tasks but also the broader business context. The developers contributed to several important initiatives, including the implementation of an AI agent, and helped us move projects forward faster while keeping development costs under control. UASOFTDEV delivered what they promised. The process was straightforward, communication was reliable, and the developers were able to start working quickly without compromising on quality. The pricing was a good fit for our budget, and the overall value for cost was excellent. I also appreciated the cultural fit and the team's ability to communicate effectively and take ownership of their work. I would definitely recommend UASOFTDEV to companies looking for reliable staff augmentation with senior Ukrainian developers. They are a trustworthy partner that can provide strong engineering talent quickly and help businesses deliver important initiatives without the overhead of a lengthy hiring process.
