Square is going to make a hardware wallet for bitcoin, the company’s hardware lead, Jesse Dorogusker, announced on Thursday. CEO Jack Dorsey, who is also the CEO of Twitter, had said in June (in a tweetstorm, naturally) that the company was considering making one, and now Square has made the decision to move forward.

“We have decided to build a hardware wallet and service to make bitcoin custody more mainstream,” Dorogusker said. “We’ll continue to ask and answer questions in the open. This community’s response to our thread about this project has been awesome - encouraging, generous, collaborative, & inspiring.
