RedDuck

I don’t have a position inside the company. I helped set it up and created the idea. We’re building a blockchain crime game, which is something new. Users can steal money from each other, buy weapons, make themselves stronger, play with a spinning wheel to get special perks, and more.

We were searching for a programming company to help us build the project.

RedDuck has done everything related to development, including PHP, blockchain programming, and design. The project is built on Phantom. They’ve delivered the whole game, and everything is working. However, we have many new ideas that we want to add.

We’ve met Mark (CTO) and worked with Stanislav (.NET Developer), the manager of our project. Then, we have two main developers who basically do everything and someone who does all the design changes.

We initially built the game with a Chinese company. We wanted to do an audit, but they didn’t want to give us the codes to do it, so we felt a bit strange. Later, we took the code, made the audit, and found out that they’d made some holes so the money would go to them. We directly killed that project, and I went to my business partners to tell them we needed a trustworthy team.

We’ve spent between $60,000–$80,000. Right now, we pay a bit over $10,000 per month.

We started working together in August 2021, and our relationship is ongoing. We hope it won’t end.

We went to a professional audit company to check to code, and it looked very professional. If they tell me something will be ready in four weeks, they actually do it in 2–3 weeks, so we like their way of working. Also, they’re good at understanding; we write everything nicely and discuss it. The communication is excellent, and things go smoothly. We’re happier with RedDuck than with all the companies we’ve worked with in the past.

We really like how they handle communication and deadlines. RedDuck works hard, and if they can’t get their stuff together, they work late in the night.

Their way of thinking stands out. Today, it’s all about the market. RedDuck is interested in similar projects, and they’ve been hanging around in the market too. If we talk to them and come up with ideas, they bring in information out of another corner, which shows their knowledge.

I live in Thailand, so it’d be nice for me if they started working at 10:00 or 11:00 a.m. I understand that it's too early for them, and they work late nights. However, it’d be a nice upgrade if they hired someone to pick up work in the morning.

You should be excited about your own project. You need to believe in it to push that feeling over to their team. Then, they can have a goal, feel good about it, and be motivated to build it. Therefore, you need to hype your own product a bit.

The scope of work covered a complete end-to-end development cycle. This included initial product design, architecture, backend and frontend development, blockchain integration, smart contract implementation, mobile app creation, and thorough testing.

The most tangible result was the successful and timely launch of the InvariFi platform — a full-featured DeFi solution delivered within the agreed budget and timeframe. The smart contracts passed independent audits without major issues, and early users reported a smooth experience with staking and yield aggregation features.

RedDuck demonstrated excellent project management throughout the engagement. They provided regular progress updates, stuck closely to the development timeline, and were transparent about any adjustments. Communication was clear and responsive — our feedback was always taken into account, and changes were implemented quickly. Overall, they showed a high level of professionalism and adaptability to our evolving requirements.

What impressed me most about RedDuck was their ability to manage a complex, full-cycle development project with both technical precision and creative vision. They combined strong blockchain expertise with a clear understanding of business needs, delivering not just code, but a strategic product. Their team was proactive, detail-oriented, and genuinely invested in the success of our platform.

Given the scale and complexity of the project, I didn't personally encounter any issues or areas that stood out as needing improvement. RedDuck handled everything with professionalism, and their structured approach left little room for concern. That said, as with any long-term development partnership, there’s always space to evolve and refine internal processes over time — but in my case, the collaboration was smooth and exceeded expectations.

The scope of the work was to develop our platform end-to-end. This includes front-end development, database layer as well as smart contract contract development. The front-end is Next.Js with PostgreSQL backend and the smart contract are EVM, built in solidity + hardhat environment.

Development of new features, their testing and progressively increasing the feature-set offered by our app.

RedDuck has been very productive in their time management and has always delivered on time. They have been very proactive in communication with daily stand-ups and managers holding the junior devs responsible for the delivery timeline promised.

The senior guys Mark & Dmytro really show care about the quality of the work their team delivers and step in as and when required. What is also very refreshing to see that the team delivered without fuss and unnecessary delays. They have also been super-active in terms of communication.

I am satisfied and thus have continued the project for more than 7 months now.

The RedDuck team responses extremely in-time. We usually set up in-day meetings so we could be on schedule and in context.

Their ability to take a deep look at a subject is impressive.

As a client we wanted project last less and cost less. But in terms of that project – we were totally satisfied. I hope that ongoing work will last the same way.

I’m a co-founder of a blockchain-based entity that pursues various projects in the crypto space. We’re a decentralized autonomous organization.

We needed a way to exhaustively and rapidly test the Solidity code we were outputting. We needed F# specialists who were really good at functional programming, specifically because functional programming has a set of features and opportunities around it that we needed to build our products.

RedDuck helped us with software development using Ethereum, Solidity, and F#. First, we communicated our software requirements to Mark (CTO), and he found us several developers on their side who could help us. He also helped us build the tapes for the first version of the product and to put that version up.

Our main point of contact was Mark (CTO), who acted as a Scrum master and product manager.

I initially found RedDuck through Upwork, and we started working via the platform.

We spent around $30,000.

We worked together from March–November 2021.

I was satisfied with the quality of RedDuck’s code and the speed at which they completed work. Our primary metrics were whether the code worked and if it was maintainable. Since I’m a developer myself, I had a look at the code that they were outputting. One of their consultants stood out for their very high-quality code.

Their project management was satisfactory regarding communication, deadlines, and staying on budget. In terms of tools, we mostly used Jira. We primarily communicated through instant messaging.

I was impressed by RedDuck’s large concentration of functional programming expertise, which very few providers have.

When I gave RedDuck negative feedback, I never got excuses from them — I got adjusted behavior. They were able to take criticism from us and adjust their approach versus blaming the circumstance. RedDuck is on the right track; they should keep doing what they’re doing, and I’m sure they’ll be incredible in a few years.

I would advise engaging with RedDuck and making sure you spend enough to gain one whole resource from them. You can expect a lot from the team because they adjust their approach to the client’s expectations. It’s okay to get a little demanding with them — you’ll get good results.
