Foresight News reports that Rex Shares and Osprey Funds have announced the launch of an ETF DOJE that tracks the performance of Dogecoin. This ETF differs from previous spot cryptocurrency ETFs that directly hold the underlying cryptocurrency, as it follows the 40-Act ETF structure and indirectly invests in the underlying cryptocurrency through futures, swaps, or other index-based instruments. The prospectus from Rex-Osprey states that approximately 80% of the fund's assets will be invested in Dogecoin instruments, which may include derivatives such as futures or swaps. Rex-Osprey previously used this approach to launch its Solana equity ETF in July.
