# EarnShares Types

## `EarnShares.Anchor`

Tempo Earn `VaultAdapter` conversion anchor.

The adapter prices vault shares against venue shares through this pair: `engineShares` venue shares are worth `shareSupply` vault shares. It is initialised 1:1 and restated on `contribute` and `migrateEngine`.

These conversions are raw and fee-blind; they ignore pending fee dilution and are unsuitable for user-facing value (use the adapter's `previewRedeem`).
