About us

The story.

ChromaWay started with the pioneering work done by Alex Mizrahi on original colored-coins since 2012, when he made the first implementation. Alex led the colored coins open source project until 2014 when he, together with Or Perelman. Iddo Bentov and Henrik Hjelte, formed Chromaway.

Since then ChromaWay has kept innovating and is behind projects and services such as Postchain, a private blockchain that combines the power of a SQL database with the security of a private blockchain. ChromaWay has also been a pioneer within using blockchain technology, being part of the first project to have a bank issue a currency on the Bitcoin Blockchain with LHV Bank in 2014. ChromaWay is also the first company to have the first Western government exploring blockchain for Land Registry with the Swedish Lantmäteriet.

Our head office in Stockholm is situated in one of the most emblematic buildings of the city, the Central Station.

We work very closely with the Stockholm Fintech Hub and with many start-up ecosystems of the city, like SUP46.
