Vaults Adapter

Guide to integrating Morpho Vault V2 with Lotus protocol via the LotusV2Adapter for allocation, deallocation, and position tracking across tranches.

Lotus integrates with Morpho's Vault V2 via a LotusV2Adapter that turns lending vault allocations into Lotus supply/withdraw actions.

Only use the adapter with Lotus markets protected against inflation attacks via an initial supply. Do not use with IRMs that can re-enter the adapter or parent vault.

When to use:

• You manage pooled assets and want to allocate across Lotus tranches.

• Your vault’s denomination asset matches the Lotus market’s loan token.

Key behaviors:

• Allocation calls supply assets to the specified market tranche.

• Deallocation withdraws back to the adapter, then to the vault.

• The adapter tracks active positions to compute realAssets().

Allocation Flow (Vault → Lotus)

Deallocation Flow (Lotus → Vault)

realAssets() = sum of supply balance across all active positions.

Constraints and safety:

• Only use markets protected against initial-supply inflation attacks.

• Do not use IRMs that can re-enter the adapter or parent vault.

• Small rounding losses can occur on supply/withdraw.
