Miami, FL – Securitize, the leading platform for tokenizing real-world assets, today announced the launch of the Mantle Index Four (MI4) Fund, a new institutional-grade digital asset product developed in partnership with Mantle, a leader in on-chain finance. MI4 is designed to meet rising demand among global allocators for professionally managed, regulated, and potentially yield-enhanced exposure to top crypto assets by market cap, without the operational complexity of direct ownership and custody.
As part of the launch, Mantle Treasury has committed $400 million as the fund’s anchor investment, reinforcing MI4’s role as a foundational building block for on-chain asset management and to advance the next generation of institutional digital asset products.
The MI4 Fund provides exposure to a diversified basket of digital assets, including BTC, ETH, SOL, and USD stablecoins/synthetic dollars, weighted by market cap and risk-adjusted. The fund rebalances quarterly and integrates staking strategies such as Mantle’s mETH, Bybit’s bbSOL, and Ethena’s USDe, aiming to enhance returns through DeFi-native yield without sacrificing compliance or investor protections.
“MI4 and associated future products will become the de facto SPX or S&P 500 of crypto – our basket of the major crypto currencies aims to capture all capital on chain looking for smart beta with income and is a set-it-and-forget-it solution for institutions without the complexities of direct custody," said Timothy Chen, Global Head of Strategy at Mantle.1
"We’re excited to launch MI4 with the Mantle team," said Carlos Domingo, Co-Founder and CEO of Securitize. "Through Securitize’s platform, investors will gain access to available real-time liquidity, the ability to use fund shares as on-chain collateral, as well as seamless interoperability with DeFi. That level of flexibility, combined with the attractive yields and institutional-grade structure, creates a product that mirrors the best of traditional finance while delivering the full potential of tokenized securities."
