The filing appeared on the Delaware Department of State's Division of Corporations site on Monday, sending XRP's price soaring by more than 10% within minutes.
It appeared days after a similar, legitimate filing from BlackRock for the creation of an ETF that holds Ethereum’s ether token.
BlackRock quickly confirmed that it was not planning the XRP ETF and the Delaware Department of State has referred the matter to the state's Department of Justice.
Last month, publication Cointelegraph falsely tweeted that the SEC had approved BlackRock to launch a US Bitcoin spot ETF, pushing the crypto's price up.
