Securitize and Mantle have announced the launch of the Mantle Index Four (MI4) Fund, an institutional-grade crypto index product designed to bridge the worlds of traditional finance (TradFi) and decentralized finance (DeFi). With a $400 million anchor investment by Mantle Treasury, the fund provides easy, diversified access to the digital asset market.
The portfolio is constantly weighted according to market size and risk criteria. It comprises top assets such as Bitcoin (BTC), Ethereum (ETH), Solana (SOL), and U.S. dollar stablecoins. The current allocation consists of 50% Bitcoin, 26.5% Ethereum, 8.5% SOL, and 15% stablecoins, reflecting a balanced approach that strikes a balance between risk and growth potential.
It also rebalances quarterly and incorporates native staking strategies—leveraging Mantle’s mETH, Bybit’s bbSOL, and Ethena’s sUSDe—to enhance yields while maintaining institutional standards for security and compliance.
Value of Securitize’s Tokenization to MI4
Securitize has built a reputation due to its work with top-tier asset managers and the launch of BlackRock’s BUIDL fund. It serves as the fund’s tokenization partner, bringing robust infrastructure and regulatory expertise to MI4.
By using Securitize’s platform, investor interests in MI4 are converted into tokens on the Mantle Network. This enables real-time on-chain liquidity and, subject to regulatory requirements, allows the use of fund tokens as collateral on supported exchanges.
The MI4 structure is a BVI Limited Partnership that employs institutional-grade infrastructure. These security measures include Fireblocks and multi-signature controls, with plans to add qualified custodians for even greater security.
It also ensures strict compliance with global securities laws by enforcing that only non-U.S. individuals or accredited investors who meet specific regulatory criteria are eligible to participate.
The Strategic Leap of Mantle
Mantle’s $400 million anchor investment, approved by its DAO, positions MI4 as the largest tokenized institutional-grade fund to date, dwarfing previous offerings like the $148 million Blockchain Capital III Digital Liquid Venture Fund (BCAP).
This launch comes amid explosive growth in the tokenized real-world asset (RWA) market, which has more than doubled in value over the past year to over $21 billion on-chain.
As institutional investors increasingly seek compliant, yield-generating exposure to crypto, MI4 is on the way to set a new standard for on-chain financial products, further blurring the lines between TradFi and DeFi.
