Portfolio Contract

A smart contract for managing diversified stablecoin yield portfolios across multiple chains and yield protocols. Also known as YMax, this proof-of-concept enables portfolio rebalancing across different yield protocols.

Overview

The YMax Portfolio Contract enables users to create and manage portfolios that deploy stablecoins across different yield-generating protocols. Users can rebalance their positions between USDN, Aave, and Compound (via cross-chain operations).
