Grayscale withdrew registration statements for three planned U.S. altcoin exchange-traded products on August 7, filing Form RW to end the registration process for its Cardano, Hedera and Polkadot ETFs. The filings were accepted between 4:33 p.m. and 4:36 p.m. Eastern Time, a span of exactly 190 seconds, and state that the registrations were never effective and that no securities were issued or sold. Grayscale said it no longer intends to proceed with the planned distribution of shares under those registration statements.

The SEC’s generic listing standards, approved in September 2025, allow qualifying commodity‑based trust shares, including digital asset products, to list without a separate Section 19(b) rule change for each fund, but they do not replace the requirement for an effective registration statement. Prior exchange listing proposals for the three funds were withdrawn by NYSE Arca on September 29, 2025, and by Nasdaq on November 3, 2025. The Cardano proposal was filed in August 2025, the Hedera proposal in September 2025, and the Polkadot proposal in August 2025, according to SEC records.

The withdrawals are not SEC rejections and do not prevent Grayscale from filing again later. SEC records show that other altcoin ETFs remain in preliminary stages, including Bittensor, Aave, BNB, NEAR and Zcash, with the Zcash registration receiving a third amendment on July 31. Grayscale also has ETFs such as the Avalanche Staking ETF, which became effective on March 11, and the Hyperliquid Staking ETF, effective on June 2.

The simultaneous withdrawal of the three filings provides no explanation beyond Grayscale’s decision not to proceed, leaving claims about investor demand, economic factors or regulatory resistance unconfirmed.
