MIP-28: [EC Proposal] Expanded Strategies and Liquidity Programs

This newly introduced strategy aims to diversify the approach to generating returns for the Mantle Treasury to finance continued ecosystem growth and other tokenomic activities. While the current strategies, such as ~5% through Treasuries backed RWA subscriptions and ~4% through ETH Staking Strategies, offer stable returns, this strategy seeks to explore opportunities with more optimized risk-return outcomes.
