Former executives of Scottish sports gaming platform FanDuel have raised what is claimed to be the UK's largest-ever seed funding round in preparation for the launch of a new online betting venture.

Based in Edinburgh, BetDEX combines blockchain technology with sports betting to bring down the cost of transactions and improve the customer experience. The protocol will be fully decentralized and open-sourced, allowing third parties to build their own applications on top of the platform. 

Set for launch in the first half of next year, BetDEX will be based in Edinburgh and is currently hiring for a variety of positions. This is backed by a $21 million (£15.6m) investment round led by San Francisco-based crypto investment firm Paradigm and Bahamas-based cryptocurrency exchange FTX.
