Crypto asset manager 21Shares has filed a registration statement with the US Securities and Exchange Commission (SEC) to launch an exchange-traded fund (ETF) tracking the price of SEI. This move follows Canary Capital’s similar application in April, signaling increasing interest in SEC-regulated crypto ETFs. The SEC filing proposes using CF Benchmarks for price tracking based on data from various crypto exchanges. 21Shares intends to utilize Coinbase Custody Trust Company as the SEI custodian while also exploring staking possibilities to generate additional returns for investors. However, the company is still assessing potential legal, regulatory, and tax risks.
