The Problem
Manually farming the best DeFi yield is gas-expensive, requires constant rebalancing across protocols, and is operationally out of reach for most retail users. Single-protocol risk concentrates exposure to one contract's exploit and economic model.
The Solution
Yearn yVaults pool deposits, socialise gas costs, and execute professionally curated and audited yield strategies on the user's behalf. Vaults are ERC-4626 compliant, multi-strategy, and modular — capital can be rebalanced across underlying protocols without user action.
Why it Matters
The original DeFi yield aggregator, live since July 2020 with ~6 years of mainnet history. V3's modular ERC-4626 architecture, fair-launched YFI governance token (no VC allocation), and yChad 6-of-9 multisig stewardship combine institutional rigor with credibly neutral governance.
