Mantle Launches the Mantle Index Four (MI4) Fund, Targeting Institutional Investors with Native Yield Generation

MI4 fills a key market gap: an institutional-grade crypto product with native yield generation, structured within a traditional fund format.

Mantle, a leading blockchain ecosystem with over $3 billion in Total Value Locked (TVL) across its core products, today announced the launch of the Mantle Index Four (MI4) Fund.

Aimed at filling a key market gap for institutional-grade crypto products with native yield generation, structured within a traditional fund format, MI4 is designed to provide both crypto-native and traditional investors with exposure to leading digital assets without the operational complexity of self-custody or active token selection.

This announcement follows the approval of a governance proposal earlier this year by the Mantle DAO for Mantle Treasury to commit up to $400 million as the anchor investment into MI4. Additionally, MI4 has selected Securitize, the leading real-world asset tokenization platform, to tokenize investors’ interests in the Fund on Mantle Network.

Combining regulated fund architecture with decentralized yield strategies, MI4 offers a unique product that integrates seamlessly into existing institutional frameworks while introducing the efficiency and flexibility of Web3 technologies.

The fund, which will be rebalanced quarterly, offers exposure to a curated basket of major assets—BTC, ETH, SOL, and USD stablecoins/synthetic dollars—with dynamic weightings guided by market capitalization and risk parameters. It also includes an initial allocation to a liquid IV uncorrelated asset and will engage in staking strategies such as mETH, Bybit’s bbSOL, and Ethena’s sUSDe to further enhance returns.

This approach aims to maximize the potential of DeFi-native yield generation without sacrificing the compliance and investor protections preferred by traditional institutions.

In essence, 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 a twist: enhanced yield through efficient, on-chain integration of staking and lending protocols.

Tokenization Enables New Levels of Liquidity and Flexibility

Having already tokenized and issued over $3 billion on-chain as of April 21, 2025, through the launch partnership for BlackRock's tokenized fund, BUIDL, which has a TVL of $2.47 billion, as well as collaborations with other top-tier asset managers, including Apollo, KKR, and Hamilton Lane, Securitize is at the forefront of tokenization.

"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."

"This partnership aligns perfectly with our vision for a vibrant and inclusive Web 3.0 ecosystem," added Timothy Chen, Global Head of Strategy at Mantle. "We're constantly seeking to innovate and provide solutions that cater to the evolving needs of the community and investors."

"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 or selecting specific tokens to hold or stake. We believe that the combination of efficient capital allocation and optimal yield generation will be highly attractive to investors."

"We've carefully engineered MI4 to meet exacting institutional standards while seeking to maximize returns for our investors. Our partnership with Securitize further reinforces our shared commitment to advancing tokenization at scale. Finally, Mantle Treasury's anchor investment demonstrates their confidence in MI4's structure and long-term value," shared Sohan Sen, Director at Mantle Guard.

"We are pleased to see the launch of the Mantle Index Four Fund. It is clear that there is a strong demand for institutional-grade crypto products, and we believe that this fund will be a valuable addition to the market. We are also proud to see the role that Securitize is playing in enabling the creation of new financial products and services through tokenization. We believe that this technology has the potential to revolutionize the way we invest, manage risk, and conduct financial transactions."

Phase 1 of MI4's rollout will take place over Q2 2025, with later phases focused on forging broader partnerships and facilitating deeper integration into the wider digital asset ecosystem.
