On April 30, 2021, Coinlive reported that the U.S. Securities and Exchange Commission (SEC) postponed its decision on the approval of several cryptocurrency ETF applications. The products involved include Franklin's SOL and XRP ETFs, Grayscale's HBAR ETF, Bitwise's DOGE ETF, the staking plans for Franklin and Fidelity's Ethereum ETFs, Franklin's cryptocurrency ETF, and Invesco Galaxy's physical subscription and redemption mechanism for Bitcoin and Ethereum ETFs.

Regulatory documents released on April 24 show that the SEC has postponed the deadline for its decision on Grayscale's application to convert the Polkadot trust into a spot ETF and Canary Capital's submitted plan for the HBAR spot ETF to June 11, while Bitwise's Bitcoin and Ethereum ETF approval has been extended to June 10.

Previously, the SEC has also postponed the approval of cryptocurrency spot ETFs multiple times, such as in 2023 regarding Bitcoin.
