+// Apyee — non-custodial multi-chain USDC yield aggregator.
+// Immutable ERC-4626 Vaults (VaultV2) deposit USDC into whitelisted DeFi
+// lending strategies (Aave V3, Compound V3, Morpho MetaMorpho, Fluid, Venus, Spark).
+// Prod deployment: v2.1.3 (2026-07-13). Audited by Soken (final PASS 91/100).
+// https://apyee.com/security
+//
+// APY methodology: net APY derived from ERC-4626 share-price growth over the
+// prior 24h window (via convertToAssets ratio, annualised daily).
+// This is inherently NET of the 15% streaming performance fee: fees accrue by
+// minting new shares to Treasury on each _accrue() hook, which dilutes existing
+// share price. So on-chain price-per-share growth reflects what a user actually
+// receives after fees — no separate subtraction required.
