Building Yearn V2
Build the most-forked vault aggregator in DeFi from scratch. Multi-strategy yield allocation, dynamic debt rebalancing, locked profit degradation, first-depositor and donation defenses, and the harvest cycle that turns strategy gains into share-price growth. Every function, every invariant. Modernized to Solidity 0.8.x.
