crypto ETFs: REXShares & Osprey filed 21 altcoin ETF proposals including staking-enabled funds — read concise coverage and key takeaways.

What did REXShares and Osprey file on October 4, 2025?

REXShares and Osprey Funds jointly submitted applications for 21 cryptocurrency exchange-traded funds (ETFs), covering established altcoins and newer tokens. The filings, labeled “subject to completion,” list assets from Cardano (ADA), Avalanche (AVAX) and Polkadot (DOT) to Hyperliquid (HYPE) and Sei (SEI).

Which assets and structures are included in the filings?

The proposals include staking-capable products such as ADA + Staking, AVAX + Staking and DOT + Staking, plus dedicated funds for Chainlink (LINK), Litecoin (LTC), Stellar (XLM) and emerging projects TAO, HYPE and SUI. Filings explicitly note that some funds are structured to incorporate on-chain staking rewards into fund returns.

How do staking-enabled ETFs differ from standard crypto ETFs?

Staking-enabled ETFs are designed to capture on-chain staking rewards and reflect them in NAV calculations. That structure requires custodial and operational arrangements to stake holdings securely while maintaining liquidity for fund redemptions. Regulators will evaluate how staking yields are earned, reported and distributed within a regulated ETF wrapper.

Why does SEC rule change matter for these filings?

The Securities and Exchange Commission’s finalized general rules for cryptocurrency spot ETFs simplified listing procedures, reducing the need for bespoke reviews. This procedural change enabled REXShares and Osprey to submit a broad slate of proposals simultaneously, increasing the likelihood of faster processing compared with prior case-by-case approaches.

Frequently Asked Questions

Which tokens are in the filings beyond ADA, AVAX and DOT?

Proposals list Chainlink (LINK), Litecoin (LTC), Stellar (XLM) and emerging assets including TAO, Hyperliquid (HYPE), Sei (SEI), Ethena (ENA) and SUI. The full list of 21 filings names both established and newer projects.

How soon could these ETFs launch if approved?

Timing depends on SEC review cycles and operational readiness. Under the new rules, approvals can move faster than prior bespoke reviews, but exact launch dates will be confirmed in fund prospectuses and SEC orders.
