Blockchain development

Our main expertise is fintech projects. We are especially good at the development of solutions for the secure exchange and storage of cryptocurrencies.

The development of cryptocurrency-related software is always a very responsible job, in which the risks of large financial losses are high. That is why we rely on highly qualified developers, effective internal processes and a deeply thought-out approach to quality control.

Languages and frameworks

Python - this programming language is used to write automated tests, for mining pool development, to quickly create various utilities.

PHP, HTML5, CSS, JavaScript/jQuery – a standard set for most web developers in the world. Each of these mature technologies is evolving and helping developers make innovative products quickly and efficiently.

Symfony 3 – ultra-modern and one of the world's most popular MVC framework. This enterprise-level platform provides a high level of quality, reliability and speed. Most of the projects that we have done in the past three years were written in Symfony. During this time we have developed an extensive library of plugins (bundles) of our own code, this provides us with the opportunity to deploy new projects on pre-prepared modules within several hours.

Ruby on Rails 5 a framework for developing Web applications by means of Ruby programming language. We apply it in non-standard projects, when we need to get the desired result quickly. The advanced mechanisms of automatic testing let our customers to be sure of the final results.

Blockchain technologies

We use the JSON-RPC API  to interact with Bitcoin and its forks. We know how to create complex transactions, we can protect the project funds by means of multisignature and cold wallet. We also have the experience of integration with well-known blockchain service providers.

The original Bitcoin Core client was written in C/C ++, Qt and continues to develop. Many blockchain forks, including those that we have developed, inherit these technologies. We are developing new Proof of Work algorithms, that applied in mining, in C++, using CUDA and OpenCL computational libraries.

We develop smart contracts for Ethereum and RSK networks using ​​Solidity and Vyper.

We know the tools Web3.js and MetaMask very well, that allows us to develop interactive web applications. 


MySQL is our primary choice when it comes to development of projects of average complexity. Whenever we are required to work with transactions, financial logic, statistics and cartography, we use PostgreSQL. Whenever we need massive reads from database and a few writes we use MongoDB. Redis – a simple and effective solution for data caching. In technologically complex projects we use a mix of different databases, leveraging the strengths of each.
In technologically complex projects we use a mix of different databases, leveraging the strengths of each.

We also have the experience of migrating a project to Microsoft SQL Server.

Tools: MySQL (MariaDB, Percona), PostgreSQL, MongoDB, Redis

JS-frameworks and libraries

Recently development of front-end components has changed, and now there are many new tools for code optimization, speed and effective development. For most of our projects we use Require.js, WebPack and Handlebars.js.

ReactJS, Angular, Backbone.js – modern tools for developing user interfaces, that we use as a base for development of single-page applications.

Gulp / Grunt – using these tools we optimize the size of images, CSS and JavaScript files and also change the way of uploading resources on clients of your project. We control how and in what volume a user will receive resources uploaded on separate pages. Each page contains only one set of resources, which is essential for its display.

Testing methodologies

The project (the most important parts or the whole code) is covered by unit-tests and functional tests for the frontend. We use a Continuous Integration approach, where tests are run automatically each time the code is updated in repository, and developer sees if his changes affects the other parts of the code.

Behavior driven development (BDD) most often we use in Agile projects, where written tests allow you to control the integrity of the project and to conduct quick changes without losing quality.     

Tools: GitLab CI, phpUnit, Rspec, Selenium, Behat, Mink, Capybara, Truffle, Remix

Search engines

When you need a large amount of filtering or searching by morphology, the standard database search is inefficient. Search engines Sphinx Search and Elastic Search create index, therefore search and filtering performed quickly and without overloading server resources.


NodeJS is a tool that we often use to write scripts inside projects.

Truffle - this framework we use to create most of the smart contracts.

Amazon Web Services (AWS) - to create a flexible infrastructure for the high load projects.

Cloudflare - we use to ensure the smooth operation of web-applications of our customers.

Blackfire – using Blackfire we measure performance of written components and applications. Tracking metrics throughout the development gives us confidence that we have written optimal and quality code.

Varnish – an http caching server for faster page loading. In some cases, it may give an increase of 20-50 times and save the server from crashes under load.

NGINX – web server, de facto standard in working with large projects.

Newrelic – a set of tools for measuring work speed and errors. Newrelic allows us to check performance and find bottlenecks in the architecture of the project. We perform load testing and make sure that the project functions under the load required by the customer.

Sentry – error logging. Allows us to locate and log errors automatically. By installing this tool on each project after its implementation and launch, we can monitor and then eliminate bugs after release.

RabbitMQ – the message manager allows us to balance the load in complex projects, simplifies the scaling and makes the code easy to understand.


  • With the AXIOMA team, we have been closely cooperating for 3 years already, and during this time we carried out many different projects together.

    I was satisfied with not only the development but also the support services. First of all, I was impressed by the speed of work, thanks to which I got an opportunity to test my business idea with a minimum of resources by creating a test version of the software for it 3 times faster than in similar projects.

    It is also comfortable to cooperate because with AXIOMA I can take an active part at every stage of development and, moreover, I can make adjustments at any time. The advantage of AGILE / SCRUM methodology is obvious in case of the non-standard project and works best in a rapidly changing market.

  • I heard about AXIOMA almost 4 years ago and when I invited guys for a small test project to develop the lending and its bundles with the payment system in order to check the Axioma for strength - we could not afford to risk when working with the main processes (B2B sales of cut flowers and potted plants).

    As a result, the team coped with the task perfectly, and since then we have trusted them with all of its tasks relating to the web: from the design and development of a personal cabinet for customers to the creation of a floral online exchange from scratch.

    Initially, we conducted projects on the classic "waterfall" scheme, but then AXIOMA proposed the AGILE / SCRUM approach. We ourselves adhered to this approach in internal development, therefore, after the first successfully completed project, we became convinced of the obvious advantages of this methodology and completely switched to SCRUM on all our joint projects.

  • AXIOMA coped perfectly with all project tasks: to create CRYXUS exchange and TheBestCoin cryptocurrency (Vertcoin fork). Guys conducted a large-scale study and selected the optimal solutions (both for business and for the stack of technologies), helped with the legal part and the product presentations development design.

    As developers, AXIOMA created for us a cryptocurrency exchange and organized a safe work with wallets. In the fork project, a new ASIC-stable block system was launched (basing on the Vertcoin fork) with the encryption algorithm and controlled memory consumption. Also, the team created an additional block infrastructure.

    At all stages, we were involved in the process and our wishes were taken into consideration. As a result, we are satisfied with AXIOMA as a team of developers, and as a business partner. They help with the project both in the area of their core competence and in related areas.

    The company is focused on the result and steadily increases its level, so it is pleasant to work with them.

  • We'd like to thank the AXIOMA team for being so wise and active during our project development. They made a lot of very valuable suggestions in order to achieve the results-oriented goals.

  • There was a task to create a site for online sales in the electronic cigarettes market. I managed to start cooperation with one of the Russian companies, but I was not satisfied with the work: the site did not meet expectations and was poorly technically implemented. In this situation, additional expenses of finance and time were inevitable, since the work had to be corrected.

    Then I decided to go to another company, which in a short time will be able to bring the site to the level I need and make it fully ready to work. And it was AXIOMA that coped with this task so the project was launched with minimal time losses.

    After the past bitter experience, I fully appreciated the fact that with AXIOMA I had the opportunity to participate in all stages of development because the team is working with AGILE/SCRUM. I am grateful to the team and developers for their professionalism.
