The MI4 fund, an institutional-grade digital asset index fund, marks a significant advancement in on-chain financial services
Mantle launched the Mantle Index Four (MI4) Fund with Securitize as Tokenisation Partner and Mantle Treasury as Anchor Investor.
The MI4 fund fills a key market gap as an institutional-grade crypto product with native yield generation, structured within a traditional fund format. Tailored for both crypto-native and traditional investors, MI4 offers access to leading digital assets without the operational complexity of self-custody or active token selection.
Mantle Treasury has committed up to US$400 million as the anchor investment into the MI4 fund, following the approval of a governance proposal by the DAO earlier this year. MI4 has also chosen Securitize to tokenise investors’ interests in the Fund on Mantle Network.
Investors gain streamlined exposure to a curated basket of major assets — BTC, ETH, SOL, and USD stablecoins/synthetic dollars — with dynamic weights guided by market capitalisation and risk parameters.
The MI4 fund rebalances quarterly and integrates staking strategies such as Mantle’s mETH, Bybit’s bbSOL, and Ethena’s sUSDe, aiming to enhance returns through DeFi-native yield without sacrificing compliance or investor protections.
“MI4 and associated future products aim to become standards in 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.
“We’ve engineered MI4 to meet exacting institutional standards while seeking to deliver enhanced returns, and our partnership with Securitize reinforces our shared commitment to advancing tokenisation at scale. Mantle Treasury’s anchor investment showcases their confidence in MI4’s structure and long-term value,” shared Sohan Sen, Director at Mantle Guard.
“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 tokenised securities.”
