BlackRock plans to stake most of its Ethereum holdings through a new exchange-traded fund structure, according to a filing with the Securities and Exchange Commission.

The iShares Staked Ethereum Trust ETF seeks to stake 70% to 90% of its Ethereum holdings under normal market circumstances, the filing shows. The product will hold Ethereum and distribute staking rewards, minus fees, to shareholders at least quarterly.

The trust will use third-party staking service providers selected by the Ether Custodian to operate validators. Coinbase Custody Trust Company will serve as the primary custodian, while Anchorage Digital Bank has been added as an alternative custodian.

The trust may reduce staking if the sponsor determines the activity raises regulatory concerns or risks the trust’s grantor trust tax status. Shares will trade on Nasdaq under the ticker symbol ETHB.

This is a developing story.
