Rex Shares has filed an application to launch an exchange-traded fund (ETF) that supports BNB staking, according to a tweet by Bloomberg ETF analyst Eric Balchunas. This move marks a significant step as it would be one of the first ETFs to incorporate staking of Binance Coin (BNB), potentially offering investors a new avenue for exposure to the cryptocurrency market. The application is currently under review, and if approved, it could pave the way for further integration of staking services into traditional financial products.
