Digital Asset, the blockchain firm set-up by former J.P. Morgan executive Blythe Masters, has made a number of new senior hires.

Carol Mathis has joined the firm as chief financial officer from RBS Corporate and Institutional Bank.

Kelly Mathieson, the former head of J.P.Morgan’s global collateral management and securities clearing businesses, has also been hired as a product manager.

Meanwhile Gavin Wells, who spent eight years at LCH.Clearnet, becomes head of Europe while Bank of America executive Gordon Weir is the firm’s new head of delivery.

Andrew Pisano, who helped define derivative exchange CME’s blockchain strategy, has been appointed as business development director.

Emnet Rios joins from RBS as director of finance and Martin Korbmacher, founder and managing director of Event Horizon Capital & Advisory, is now a strategic advisor tasked with helping scale Digital Asset’s growth.

Mathieson, Pisano, Mathis and Rios are based in New York, while Wells and Weir are based in London. Korbmacher will be based in Frankfurt.

Earlier this year, Digital Asset announced that it was opening a London office to support its clients and increase its presence in the UK and European markets.

Justin Amos was appointed as head of Europe but soon relocated to Sydney to build out Digital Asset’s Australia office.

The firm is working with Australia's stock exchange ASX on the world’s first national scale post-trade solution using distributed ledger technology.
