ChainCatcher news, according to The Block, when asked whether there are plans to follow up with the launch of a Solana ETF, Rachel Aguirre, head of BlackRock's iShares product division in the U.S., did not provide a specific answer but reiterated that the company will focus on three core principles."First, what do clients need? Second, what is the investment thesis? In the world of cryptocurrency, not all coins are the same, and this investment thesis is very important. Third, is it suitable for an ETF structure? Is there enough liquidity? Can it support transparency, etc.? So our principles remain unchanged, whether it's an active management strategy, a strategy using options and other derivatives, or a strategy in the cryptocurrency space."
