The president of cryptocurrency exchange FTX US, Brett Harrison, has announced he will be transitioning into an advisory role in the next few months.

In a Tuesday announcement on Twitter, Harrison said he will be resigning his position as FTX US president but remain with the exchange “with the goal of removing technological barriers to full participation in and maturation of global crypto markets, both centralized and decentralized.” Harrison had worked as FTX US president since May 2021 following a job at Citadel Securities.

“I can’t wait to share more about what I’m doing next,” said Harrison. “Until then, I’ll be assisting Sam [Bankman-Fried] and the team with this transition to ensure FTX ends the year with all its characteristic momentum.”

Harrison’s announcement followed another high profile resignation in the crypto space as Alex Mashinsky said on Tuesday he would be leaving his position as Celsius CEO effective immediately, citing “difficult financial circumstances” users were facing. On Sept. 21, Kraken’s Jesse Powell announced chief operating officer Dave Ripley will be replacing him as CEO once Ripley’s position was filled. Powell will stay on with the exchange as a board member.
