SINGAPORE -- Mantle, a leading blockchain ecosystem at the forefront of decentralized finance (DeFi) with over $3 billion in Total Value Locked (TVL) across its core products, announced the launch of the Mantle Index Four (MI4) Fund. MI4 fills a key market gap: 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 $400 million as the anchor investment into MI4, following the approval of a governance proposal by the DAO earlier this year. MI4 has also chosen Securitize, the leading real-world asset tokenization platform, to tokenize investors’ interests in the Fund on Mantle Network.

Structured as a BVI Limited Partnership and managed by Mantle Guard Limited (a newly established investment manager), MI4 combines regulated fund architecture with decentralized yield strategies. 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 capitalization and risk parameters.

The 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.

All assets leverage institutional-grade infrastructure, including Fireblocks and multi-signature controls, with qualified custodians under consideration for added security in the future.

MI4 is designed to become a new financial primitive—a bridge between TradFi and DeFi—positioned to serve as a benchmark for crypto beta exposure with yield enhancement.

Harnessing Tokenization's Fullest Potential

As of April 21, 2025, Securitize has tokenized and issued over $3 billion on-chain, as the launch partner for BlackRock's tokenized fund, BUIDL, with a TVL of $2.47 billion, as well as collaborations with other top-tier asset managers, including Apollo, KKR, and Hamilton Lane.

By leveraging Securitize’s tokenization infrastructure, MI4 investors can tokenize their fund interests. The tokenized interests can be transferred on Mantle Network between authorized participants in accordance with applicable private placement laws, unlocking crypto-native advantages such as real-time on-chain liquidity and, in compliance with the MI4’s transfer provisions, the ability to use the tokenized fund as collateral for leverage on supported exchanges.

“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.[1]

"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 tokenization 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.[2]

“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.”

MI4’s initial rollout in Phase 1 will take place over Q2 2025, with future phases focused on broadening partnership and integration in the wider digital asset ecosystem.
