Simple Exposure to Spot Crypto
At REX, we are building the next generation of crypto ETFs designed to give investors and advisors direct spot exposure to digital assets through the 40 act ETF structure.

Staking Innovation in an ETF
REX-Osprey ETFs introduce native, on-chain staking rewards into an ETF structure where applicable for proof-of-stake protocols. This innovation allows investors to benefit from staking yields while retaining the simplicity and accessibility of ETFs.

Exposure to Spot Crypto
Each fund is built to provide exposure to the underlying cryptocurrency itself, not derivatives or synthetic strategies. Investors gain exposure to spot crypto through an ETF that trades on exchange like a stock.

Innovative 40 Act Structure
REX was the first to file crypto ETFs under the Investment Company Act of 1940, allowing crypto ETFs that hold the majority of their spot assets directly and, where applicable, distribute staking rewards.

Frequently Asked Questions – REX-Osprey™ Crypto ETFs
A family of ETFs providing direct exposure to spot cryptocurrencies. These funds do not use swaps, futures, or synthetic derivatives.
Before SSK and ESK, U.S. spot crypto products were limited to 1933 Act grantor trusts. They were slow to launch, restricted to single static assets, and prohibited from staking. REX broke new ground by launching the first 1940 Act ETFs that provide true spot exposure and, where applicable, staking income.
Yes. That is the defining feature of the REX-Osprey suite. Each ETF is designed to hold spot crypto directly (or through a compliant ETP) so investors gain exposure to the actual digital asset.
This represents a structural breakthrough. For the first time, advisors and institutions can access spot crypto in a 1940 Act ETF wrapper, with the added potential of staking income and the accessibility of traditional ETFs.
