PANews reported on April 24 that according to The Block, real-world asset tokenization company Securitize has partnered with Mantle to launch a new institutional crypto index fund, with Mantle pledging $400 million as the cornerstone investment for the fund. The Mantle Index Four (MI4) fund aims to invest in top crypto assets, including BTC, ETH, SOL, and USD stablecoins, with the goal of becoming the "S&P 500 in the cryptocurrency space."
