Asset management giant BlackRock (BLK) has registered an iShares Ethereum Trust in Delaware, according to a new filing on Thursday.

BlackRock registered its iShares Bitcoin Trust in that state on June 8 – a week before the firm filed its spot bitcoin exchange-traded fund (ETF) application with the U.S. Securities and Exchange Commission (SEC).

The new filing with the Delaware Department of State Division of Corporations was submitted under the name of BlackRock Advisors.

Companies often have a legal presence in Delaware for the generous tax benefits. The filing suggests that one of the world’s largest asset managers is preparing to double down on crypto.

If the prior schedule holds true, a filing for the Ethereum Trust could appear on the SEC’s site next week.

BlackRock declined to comment to an Unchained request for comment.

BlackRock is widely considered the leader of a pack of companies awaiting potential SEC approval for spot bitcoin ETFs.

A CoinDesk report last week suggested that top market makers such as Jane Street and Jump Trading have offered to provide liquidity to BlackRock’s bitcoin ETF once it’s approved. Optimism about a potential approval drove bitcoin (BTC) 27% higher in October.

The price of the Ethereum token ether (ETH) was recently up 6.5% to $2,010.97 following the news.
