Pooled lending protocols bundle risk decisions into governance: which assets, what parameters, which oracles, all adjustable by vote. Morpho separates the machinery from the judgement. The core creates isolated markets whose parameters cannot change, and curated vaults allocate deposits across those markets under a named manager's mandate.
Why immutability matters
An upgradeable lending contract can be changed by whoever holds the keys, whether through legitimate governance or a compromise. Morpho's core cannot. The market you deposited into on day one has the same collateral, the same LTV and the same oracle on day one thousand. In a sector where governance attacks and rushed parameter changes have caused real losses, that guarantee is worth a great deal.
Better rates, and why
Direct market structure with no pooled utilisation curve smoothing rates means lenders capture more of what borrowers pay. Rates are typically better than Aave's on comparable risk, which is the commercial argument for using it.
Where the risk moved
To curation. Anyone can create a market, including badly parameterised ones, and vault curators choose which to allocate to. Some have reached for yield in markets backed by long-tail collateral that subsequently went bad. Read the vault's market list before depositing — it is visible on-chain, which is the whole point.
Who should use it
Depositors who will evaluate the specific vault and curator, and borrowers wanting better rates against blue-chip collateral. Users who want one conservative decision made for them should use Aave.
