0.9.6 — 2026-04-16

Added

  • High Efficiency (HE) mode — pools can define HE asset groups via poolAssetsHEConfig, each with a heCategory number. activeHeCategory activates when all borrows belong to a single HE category and the total borrow exceeds the standard collateral limit. The HE borrow limit is calculated from supply assets within the same HE category using heCollateralFactor and heLiquidationThreshold instead of standard values, allowing higher LTV within the category.
  • activeHeCategory field in UserData — -1 means HE is inactive, positive integer is the active category
  • predictedHeCategory field in UserData — HE category that would activate on next borrow (based on current supply), used to show available HE borrow limit in UI
  • borrowLimitsWithEmode field in UserData — per-asset max borrow amounts under HE limits
  • availableToBorrowWithEmode field in UserData — total available to borrow under HE limits
  • New functions:
    • determineHeCategory() — derives active HE category from current borrows
    • exceedsStandardBorrowLimit() — checks whether total borrow exceeds standard collateral limit
    • getAvailableToBorrowWithEMode() — available-to-borrow under HE limits; shows HE limit whenever all borrows are within a single HE category, regardless of whether standard limit is already exceeded
    • calculateRepayToExitEMode() — how much to repay to drop back to standard mode
  • New types: PoolAssetHEConfig (title, assets, heCategory)

Fixed

  • predictHealthFactor now applies HE thresholds only when borrow exceeds the standard collateral limit
  • ClassicCollector now fetches prices from all sources in parallel via Promise.any instead of sequentially
