Notes ​

  • yrUSDC is the ERC-4626 share token minted by YearRingCoreVaultV21. Price Per Share is derived from convertToAssets(1e18) — not set by admin.
  • PointsLedgerV01 records non-transferable internal Points. Points are not ERC-20 tokens and have no guaranteed market value.
  • AccessStrategyManagerV21 is the entry point for lock-eligible users; CoreStrategyManagerV21 handles general capital deployment.
  • Two AaveUSDCStrategyV21 instances exist: one connected to CoreStrategyManagerV21 and one to AccessStrategyManagerV21.
