Internet reports that according to a filing with regulators on Monday, Hasdex has asked the U.S. Securities and Exchange Commission to approve an amendment that would allow the digital asset management company to add XRP, Solana, Cardano and other major altcoins to its Hashdex Nasdaq Crypto Index U.S. ETF (NCIQ). The fund currently focuses on Bitcoin, tracking a smaller proportion of Ethereum, and will also include Chain, Uniswap, Litecoin and Avalanche. The filing comes as issuers are working to increase coverage of altcoins in their crypto tracking exchange-traded funds. In recent months, fund managers have proposed new investment products that directly track the prices of various cryptocurrencies, from Dogecoin to XRP, Solana, and even Donald Trump's official memorandum coin. On Monday, Canary Capital applied for an ETF based on SUI, a native token on the 1-layer Sui blockchain.
