Tess Rinearson, Twitter's Crypto Lead, has left the company, tweeting a salute and a blue heart emoji.
Rinearson, whose Twitter account is currently private, resides in Berlin, Germany.
"I am extremely proud of everything the Twitter crypto team has accomplished."
"I'm sad that I won't be able to see it through to the end," Rinearson wrote on Twitter on Friday.
"However, there are still MANY brilliant and considerate employees at the company."
While Twitter's crypto lead and countless others may have left the company, the company is still thriving.
According to rumours, a planned crypto wallet function for the site has been halted since Musk took charge.
