Hasdex has submitted an application to the U.S. Securities and Exchange Commission (SEC) for approval of an amendment that would allow the digital asset management company to include Ripple ($XRP), Solana ($SOL), Cardano ($ADA), and other major altcoins in its Hashdex Nasdaq Crypto Index U.S. ETF (NCIQ). According to documents submitted to the regulator on Monday, the fund currently focuses primarily on Bitcoin and tracks a smaller proportion of Ethereum, while also including Chainlink, Uniswap, Litecoin, and Avalanche.
