SEC sent a letter to ETF Opportunities Trust raising concerns about legal risks in the structure of Staking ETFs that allow investors to earn yield by locking tokens.
REX Financial won't proceed with Staking ETFs until SEC's concerns are addressed, aiming to meet the legal definition of an investment company.
Despite the setback, analysts believe Staking ETFs are inevitable and expect more compliant approaches to succeed in the future.
SEC's warning has frozen REX Financial's mid-June launch of Staking ETFs, with regulatory action possible if issues are not resolved, as the SEC tightens its grip on ETF structures.
