How it's made
Challenges we ran into **The Problem:** DeFi protocols generate yield in completely different ways. As an example: Aave increases your aToken balance over time. Pendle has fixed maturity tokens. sUSDe auto-compounds into the token itself. Some protocols queue yield that you claim separately. We needed one vault system to handle all of them. **The Solution:** We created 5 adapter types with a unified `IYieldAdapter` interface: - **BalanceGrowth** (Aave): Tracks liquidity index, balance grows automatically - **CompoundingValue** (stETH, sUSDe): Token value increases, not balance - **FixedMaturityToken** (Pendle): Principal tokens with maturity dates, rollover logic - **ClaimableYield**: Yield queued separately, claim then distribute - **Manual**: Off-chain management with on-chain attestation Each adapter translates protocol-specific yield into a common harvest() function. The vault doesn't care *how* yield is generated—it just calls adapter.harvest() and receives profit/loss.
