therelational Speech bubble blockchain platform that makes sense

We believe in creating a platform with a technical solution that is geared for the real world, we call it relational blockchain. It is all about using our knowledge and experience of combining blockchain and traditional databases creating something that people actually can relate to, in an environment that people are familiar with and in a language that everyone can learn.

Projects on Chromia

From Games to Enterprise, Chromia makes it really easy to do mainstream applications.

The Green Assets Wallet is the first enterprise blockchain platform for green bond validation and impact reporting. Co-created by a unique consortium of leading capital market actors, green finance experts and technology innovators formed under the lead of Stockholm Green Digital Finance, the Green Assets Wallet is designed to inject efficiency and transparency to the green debt market. The Green Assets Wallet is the first Enterprise dapp on Chromia.

Relational blockchain geared for the real world

Relational blockchain = relational database + blockchain.

A blockchain is a a simple list of transactions. Finding anything there requires you to search everything from start to end.

A relational database is the tech that powers your social network, your bank, all your non-trivial applications.

Our technical solution is for the real world.

Our goal is to provide an opportunity for you to create a fully decentralized application (dapp) on your own terms. In short, Chromia is ready to be used by anyone having the cool ideas, not only by those having the technical skills.

So we created RELL, our take on a universal language that is easier to learn and more efficient to work with. It's based on SQL, which most developers know. Rell is highly efficient and permits fewer lines of code than other blockchain languages.

Try our tools building tomorrow's applications

Our listed features are examples of how to make the ecosystem neat and nice. Try our Vault and Block Explorer live on Testnet.

Block Explorer
Our Block Explorer allows users and developers to retrieve data from any block on the blockchain at maximum speed, thanks to our relational blockchain technology, which means that it does not need an external server to index information.
The Chromia Vault keeps all your dapps and assets in one place. Its functional design allows you to go from one dapp to another without ever having to log out, lose any data or cancel any transaction. The Vault is constructed to make the user experience and interaction a simple ride, not a marathon.
Single Sign On
The Chromia Vault Single Sign On (SSO) is a unique feature created to reduce password entering without compromising your security. It is in many ways easier than any other existing unified login system, centralized or not. (Read more).


Chromia is the brainchild of ChromaWay, a pioneering blockchain company. After working for several years in building the perfect mix between relational databases and blockchain, they decided to build a platform for everyone with the same underlying technology.

Back in 2012, Alex Mizrahi the CTO started working together on what can be called the first implementation of user-defined assets on a blockchain, called colored coins. This creation was absolutely revolutionary. We are sure you have heard about tokens.

Since 2014, the three co-founders have been working on solutions for banks, enterprises, governments and private institutions and have built a team with people from all over the world. ChromaWay is a free and open source software company since always, and will not be controlling Chromia which is a true decentralized platform.

I found out that there was a workshop for Rell (the programming language for writing dapps on Chromia) in Stockholm. So I went and was pleasantly surprised how easy it looked. I always thought that building something on the blockchain would be difficult. However, with Chromia and Rell, it really is not.

I got to know Chromia through my friend, and co-creator of Chain of Alliance, Simon, who was looking for a suiting platform to develop our dapp on. The reason we chose Chromia is the ease to develop on their platform, great support and it offers the functionalities we need to implement our dapp.
