The ETF will custody assets with Coinbase and may engage in staking, while SEI traded at $0.29 at press time.

21Shares has filed a registration statement (S-1) with the SEC for a SEI exchange-traded fund (ETF), expanding its lineup of single-asset crypto investment products.

The planned 21Shares SEI ETF would track the CF SEI-Dollar Reference Rate in US dollars. The product is structured as a passive fund holding SEI in custody with Coinbase Trust, without using leverage or derivatives.

The fund could also stake part of its SEI holdings to earn rewards, but 21Shares said it has not yet decided whether to pursue that option.

The Sei Network is a Layer 1 blockchain built for high-speed trading and exchange-focused apps. Its native token, SEI, is used for fees, governance, and staking.
