Morpho Blue, MetaMorpho V2, and the markets-plus-vaults model

Morpho's design separates two jobs that older lending protocols bundled together: creating a lending market, and allocating capital across markets. Morpho Blue handles the first. MetaMorpho vaults handle the second. The split is a useful way to understand how isolated-market lending works in practice.

How it works

Morpho Blue is the base layer: a minimal, immutable contract for creating isolated lending markets. Each market is defined by four things fixed at creation: one collateral asset, one loan asset, one oracle and one liquidation threshold (LLTV). Once deployed, those parameters can't change. The contract is deliberately small, which makes it easier to audit, and anyone can create a new market for any asset pairing. On its own, though, it's bare: a lender using it directly has to choose a market, monitor it and move capital by hand.

MetaMorpho vaults sit on top and handle that allocation. A vault takes depositors' capital and spreads it across Morpho Blue markets according to a strategy set by a curator, who decides which markets the vault can lend into and the maximum it can put in each. Depositors hold one position; the curator manages which markets are used and in what proportion. MetaMorpho V2 adds finer controls: clearer role separation, more granular risk caps and tighter governance over what curators can do.

The result is a division of labor. Risk isolation lives at the bottom; allocation and diversification live on top.

Why it matters

Pure isolated markets contain risk well but are fragmented: a depositor doesn't want to pick and watch individual markets. Pooled protocols are convenient but share risk across every asset. The two-layer model aims to keep the isolation of the first and the convenience of the second.

It also makes curation visible. Because a vault's allowed markets and caps are set on-chain, depositors can see which markets a vault can touch and how much it can put in each, instead of relying on a discretionary decision they can't inspect.

What to check

When evaluating any vault built this way, look at who the curator is, which markets the vault is allowed to use, the caps on each, the oracles those markets rely on, and the audit history of both layers.
