About BlockTech



BlockTech (originally known as CRATR) was founded by experienced professionals with backgrounds in software development and derivatives trading.

By combining knowledge and experience from different fields, we were quickly capable of securing stable revenues from trading algorithms in the cryptocurrency market.

Currently, we are mainly active in the field of cryptocurrency derivatives trading. A new and fast-growing derivatives market that is rapidly expanding. Our aim is to expand our current backbone, which consists of both Bitcoin and Ethereum options and futures, into more types of cryptocurrencies and exchanges.

As a company, we believe we can help to shape the future by developing tools which improve trading practices and liquidity within the market.



It is our mission to improve transparency and increase liquidity within the market.

This has made the company successful so far. We believe in a democratic trading system in which participants should be free of counterparty risk. But our goal is to go further than this.

Blockchain technology is relatively new and we believe it will change the future. We want to be on the forefront of these developments, create new ways of using blockchain technology and help develop innovative software in the process.



The decentralization of proof of assets is an inevitable development and we are here to facilitate liquidity to speed up the process.

We use complicated mathematical formulas to improve the speed and accuracy of derivatives trading with a network spanning across the globe. To facilitate our trading applications, we use top tier hardware.
