21Shares has launched its U.S. spot XRP ETF, TOXR, on the Cboe BZX Exchange, marking its entry as the fifth XRP ETF in the United States. The ETF, which carries a 0.50% management fee, follows a cryptic social media hint from the company. Existing XRP ETFs have experienced significant interest, with $666 million in net inflows recorded in less than a month and no outflows in the past ten trading days. This surge in demand has led analysts to speculate about a potential supply shock that could affect XRP's price.
