Aquis Exchange, a challenger to the City's largest trading venues, has scored a win for its growing technology business with a mandate to power one of a new breed of cryptocurrency markets.

Aquis, founded by trading veteran Alasdair Haynes, will provide the technology to allow buyers and sellers of cryptocurrencies and tokens to be matched on Archax, an exchange that plans to go live in the first half of 2019, the companies said in a statement on Thursday.
