Online reports that Cboe BZX Exchange filed a 19b-4 document on behalf of Bitwise, 21Shares, WisdomTree and Canary Capital to list and trade spot exchange-traded products that track XRP, the fourth largest cryptocurrency by market cap. The 19b-4 application is the second part of the two-step process for filing a cryptocurrency ETF application with the U.S. Securities and Exchange Commission. Once approved by the Securities and Exchange Commission, the application will be published in the Federal Register, initiating the agency's approval process. Bitwise filed its first registration for the spot XRP ETF in October, while 21Shares filed its S-1 registration statement for the XRP ETF with the U.S. Securities and Exchange Commission in November.
