European Blockchain Company

CTG Blockchain is a European technology company with multiple offices and a focus on consulting services for the blockchain startups. We are linked by a long history of cooperation and several successfully created products. This time we had to rethink the archaic design of our partner's old website and create a modern business product for them.

General principles

Like any Western European company, CTG Blockchain strives on maintaining business continuity and integrations from early business stages and not making any U-turns towards trendy design solutions. The German sophistication of our partners is perfectly combined with our approach to business, so we decided to stick to a strict style and minimalism.The products and services we worked on included: the main pages of the CTG Blockchain website; Company blog; page with an investment banking offer in cryptocurrencies; investor's personal account; the announcement page of the international blockchain event, which is organized annually by CTG Blockchain. Since the client did not know where to start, but certainly trusted us, we agreed on working groups and got to work.

Branding and logo

Our client's previous site didn't even have a logo, just a company name. We decided to experiment a little with the brand and refresh it. A study of the market and competitors was made, and the hypothesis was confirmed that it is possible to stand out among competitors' companies by conciseness and simplicity, without overloading users with annoying graphic effects. A new logo was developed for the company, the corporate font and colors were changed, a style guide was created.

Main page

It was decided to abandon the multi-page corporate website concept in favor of a modern solution with several linked landing pages, each serving its own purpose. The main page of the site explains to users the client's business and introduces the list of services.Partners and clients of CTG Blockchain are located on all continents and time zones, so it is important that the project supports all the largest language groups.

Community / blog

A business working with crypto startups always accumulates large volumes of rare or unique information that could potentially be useful to other market participants. The blog helps to share valuable experience, as well as tell stories that can help prevent the development of scam projects, influence the strengthening of blockchain security protocols, or evaluate the investment attractiveness of developing projects.


An important part of the platform is a non-public investment offer. The leaders of CTG Blockchain offer their VIP clients the opportunity to increase their assets in cryptocurrencies thanks to an investment plan fixed in a smart contract. Our team created all these mechanics from scratch based on the Ethtereum blockchain. We created and then audited smart contracts to make sure that automation of depositing, earning and withdrawing funds is absolutely safe.

Personal area

The investor's personal account is similar to a bank account, which in fact is, with the exception of a cryptocurrency, and not a traditional, account. Unfortunately, we cannot publicly disclose the terms of investment and the calculation of yield, because we are bound by NDA policy, but we can talk a little about this.Each new investment is a new voucher with its own conditions. Users cannot increase the deposit amount of the old voucher, but are required to open a new one in order not to reveal the calculation of the compound interest of previous deposits.


We implemented a multilingual site and we worked with native speakers of 4 languages so that in addition to the English version of the site, users could use: German, Spanish, Russian and Chinese. From a design point of view, multilingualism always involves a lot of work, because it is necessary to almost redo the UI for each language, and then adapt it for devices, as a result of which the layout for layout increases in size by a multiple of the languages used.


As we said earlier, in addition to the main page and the investment landing page, the project contains an event page, but it is created twice a year, so we did not add them to this story. The main pages of the project, as well as the personal account, have been adapted for smartphones and tablets, as we always do with all projects. The main difficulty was in displaying a large amount of important information about deposits in the investor's personal account. I had to turn to the rich experience of creating dashboards and reports with a lot of data so that the user can easily control the most important data. You can see this by becoming a VIP client of the CTG Blockchain investment program, or order the development of your own investment project.

Hear from the customers

Justin Jackson
CEO at Vehicle Approval Centre

Before I hired Interactive Design, my website was a disaster. The branding was terrible, user-flow was not friendly, and it was just ugly. I knew what I wanted but I couldn't seem to find a company that understood my vision until I met with Interactive Design.

They listened very carefully to my wants and needs and then added even more value by suggesting things that I would have never thought of on my own. It was incredible.They went above and beyond for me, numerous times, to help accomplish such a beautiful website!

Their customer service is next to none. They are always there when I need them, even after the job was successfully completed – that is a trait that you just can't find anywhere else.I continue to work with them daily as I consider them a part of my team now.A fantastic group of very knowledgable people!

The team is very professional. They understood the needs very well, were very resilient in overcoming difficulties or problems. So we are grateful to them for that.

I appreciate their talented work, their design experience, their understanding of business specifications. They are very good partners to work with, I highly recommend them.
