Crypto trading firm GSR has applied for an exchange-traded fund based on the performance of cryptocurrency treasuries, according to a Wednesday filing with the U.S. Securities and Exchange Commission that included proposals for four other funds focused on Ethereum and staking. The GSR Digital Asset Treasury Companies ETF will invest at least 80% of its assets in firms that hold cryptocurrencies in their corporate treasuries, according to the N-1A registration statement. The ETF, which will initially hold 10-15 positions, will target companies listed on U.S. stock exchanges, although it may also include private investments in public equity (PIPE).
