Mantle has launched the Mantle Index Four Fund or MI4, a new institutional-grade digital asset index fund with Securitize as its tokenization partner.

According to a press release shared with crypto.news, the fund aims to offer institutional investors a crypto product featuring native yield generation within a familiar traditional fund structure. The initial rollout is scheduled for the second quarter of 2025.

After receiving approval from the Mantle DAO earlier this year, the Mantle (MNT) Treasury has pledged $400 million as the MI4’s initial investment. The protocol has also tapped real-world asset tokenization platform Securitize as the fund’s official tokenization partner.

MI4 seeks to bridge the gap between traditional finance and decentralized finance by combining regulated fund structures with decentralized yield strategies. The fund gives institutional investors exposure to major digital assets without requiring them to select individual tokens or manage self-custody.

The assets offered through MI4 include Bitcoin (BTC), Ethereum (ETH), Solana (SOL) and USD stablecoins or synthetic dollars.

The fund also features integrated risk management, quarterly rebalancing, and yield optimization strategies. These include staking products such as Mantle’s mETH, Bybit’s bbSOL, and Ethena’s sUSDe. The goal is to provide yield generation while remaining compliant with regulatory standards and investor protection rules.

With Securitize as the fund’s tokenization partner, investors can tokenize their fund interests which can then be moved on-chain to the Mantle Network. These tokenized interests can be transferred under private placement regulations and MI4’s transfer provisions. Additionally, the tokenized shares may be used as collateral on supported exchanges, enhancing liquidity and utility.

Timothy Chen, Global Head of Strategy at Mantle, highlighted MI4 as a step toward making Mantle a benchmark in crypto fund offerings:

“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 Chen.

Co-Founder and CEO of Securitize, Carlos Domingo, expressed optimism regarding the launch of MI4. He explained that through Securitize’s platform, investors will be able to achieve real-time liquidity, use fund shares as collateral and take advantage of on-chain interoperability.

“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,” said Domingo.
