BlackRock Inc. is looking to launch an exchange-traded fund that would be centered on Ether, helping to spur a rally in the second-largest cryptocurrency.

Nasdaq, the exchange that BlackRock is working with on the ETF, on Thursday submitted what’s known as a 19b-4 form, marking the next step in the process to get such a fund launched. The Wall Street behemoth had earlier registered paperwork in Delaware for the fund, according to documents posted to the Delaware Department of State Division of Corporations website.
