How Morpho vaults work: MetaMorpho vs Vaults V2, curator and sentinel roles, timelocks, fees, the 2025 bad debt case, and a checklist for picking a vault.

Morpho vaults are non-custodial lending vaults built on top of Morpho's isolated lending markets. You deposit a single asset, such as USDC or WETH, and a professional curator decides which markets the vault can lend into and how much each market can receive. You earn the interest borrowers pay, minus the curator's fee, without having to pick markets yourself.
Below: markets vs vaults, MetaMorpho vs Vaults V2, roles, fees, past losses and a checklist.
Morpho has two layers, and it helps to keep them separate.
The bottom layer is the market. Morpho's documentation now calls these variable rate markets (the product long known as Morpho Blue). Each market pairs exactly one loan asset with one collateral asset and is fixed by five parameters at creation: the collateral asset, the loan asset, the liquidation loan-to-value (LLTV), the oracle, and the interest rate model. Anyone can create a market, but the LLTV and rate model must come from a governance-approved list. Once a market exists, its parameters never change, and its risk is isolated from every other market.
Isolation is good for safety but awkward for lenders, who would have to judge every oracle, collateral asset and LLTV themselves. That is the job vaults take over.
The top layer is the vault: an ERC-4626 token vault that pools one asset and spreads it across approved markets. Your shares rise in value as interest accrues. For the general idea, see crypto vaults explained.
The first Morpho vaults were called MetaMorpho. Morpho's documentation now labels them "Morpho Vaults V1 (MetaMorpho)" and treats them, and a V1.1 revision, as legacy. V1 vaults lend only into Morpho markets.
Morpho Vaults V2 launched on Ethereum at the end of September 2025, according to Morpho's launch post dated 29 September 2025. The main changes, per the Vault V2 documentation:
| Feature | Vaults V1 (MetaMorpho) | Vaults V2 |
|---|---|---|
| Where funds go | Morpho markets only | Any approved adapter |
| Risk limits | A supply cap per market | Absolute and relative caps on shared risk IDs |
| Safety role | Guardian | Sentinel |
| Timelock | One global timelock, 1 day to 2 weeks after setup | Per-function timelocks, can be made permanent |
| Fees | Performance fee up to 50% | Performance fee up to 50% plus management fee up to 5% a year |
Per Morpho's docs on timelocks and fees, read 15 October 2026.
Morpho's roles documentation sets out who can do what in a V2 vault. This is the part you are really trusting.
In V1 the safety role was the guardian, which could only revoke pending changes, and the owner held every other role's powers too.
A timelock is a public waiting period between a change being proposed and taking effect. It is your chance to withdraw, and the sentinel's chance to cancel.
In V1 there is one timelock for the whole vault, which must be between 1 day and 2 weeks once the vault is set up. In V2 each function has its own timelock. Shortening a timelock takes as long as the timelock being shortened, so a compromised key cannot drop every delay to zero at once. A curator can also abdicate a function, which disables it forever.
In MetaMorpho vaults the allocator manages two ordered lists: the supply queue (which markets receive deposits, until their caps fill) and the withdraw queue (which markets pay out withdrawals). Morpho's liquidity curation guide now recommends putting an idle position first in both queues, so ordinary deposits and withdrawals cannot shuffle funds between markets.
V2 replaces the queues. Deposits and withdrawals pass through the vault's idle balance, and one adapter can be named the liquidity adapter: new deposits go there, and withdrawals draw from it when idle funds run out. If both are empty, the vault is illiquid until the allocator moves money back from other positions. How much is available depends on how much of each market is borrowed, which is what utilisation rate measures.
Curators are paid through vault fees, taken by minting new shares to the fee recipient. In V2 the performance fee (a cut of interest, capped at 50%) and the management fee (capped at 5% of assets a year) are timelocked. In V1 there is only the performance fee, and the owner can change it without a timelock.
DefiLlama tracks curators in a "Risk Curators" category. On 15 October 2026 its protocols API listed 96 curators with about $9.5 billion between them. These figures cover all the platforms each curator works on, not only Morpho:
For comparison, DefiLlama put Morpho's market layer at about $11.0 billion supplied net of borrowing, with a further $5.6 billion borrowed, on the same date. For a broader look at the curator model across protocols, see our guide to vault curators in DeFi.
The main risk is usually the curator's choice of markets, not Morpho's code. The clearest example came in November 2025. When the synthetic stablecoin deUSD collapsed after the failure of Stream Finance, MEV Capital's Ethereum USDC vault on Morpho removed the Elixir sdeUSD/USDC market and realised bad debt equal to nearly 3.6% of the vault's assets, as reported on 13 November 2025. A third-party postmortem describes the loss as a curator allocation failure, not a protocol exploit, and notes that Elixir ran a USDC claims process for affected lenders.
When a liquidation leaves debt with no collateral behind it, per the bad debt documentation, a V2 vault lowers its total assets and every share is worth proportionally less. Everyone who held shares at that moment takes the same percentage loss. The same page warns that V1.1 vaults do not realise bad debt internally, so a V2 vault lending into a V1.1 vault may not show a loss in its share price straight away.
Every market has one oracle, fixed forever. Morpho's risk page says plainly that no oracle is immune to manipulation and that a faulty oracle can cause losses in any vault that lends to the market. A vault is only as sound as the weakest oracle among the markets it is allowed to use.
If borrowers have taken most of the cash, withdrawals wait. V2 adds a permissionless forceDeallocate route: with a flash loan, you swap vault shares for a direct position in an underlying market, paying a penalty of up to 2%. You then hold that market position, not cash, and gates can block the route.
A few curators manage most curated deposits, and each vault depends on a few multisig keys. Smart contract risk remains too, even though Morpho's core contracts are immutable, formally verified and covered by a bug bounty.

JewelSwap does not run Morpho vaults. It works on Sui, MultiversX and Radix, with liquid staking (JWLSUI, JWLEGLD, JWLXRD) and Scallop and Cetus farms on Sui. Its closest product to a curated vault is Ember Loop, a beta, unaudited Sui vault that deposits USDC into Ember Protocol's eEARN vault and loops it on Suilend using a keeper. Withdrawals are queued, fees apply, and US and UK residents should not use it. The checklist above applies to it too.
A Morpho vault is a non-custodial ERC-4626 vault that takes deposits of one asset and lends them across several Morpho markets chosen by a curator. Depositors earn the interest borrowers pay, minus the curator's fees.
Yes. MetaMorpho was the original name of Morpho's vaults. Morpho's documentation now calls them Morpho Vaults V1 and treats them as legacy, with Morpho Vaults V2 launched in late September 2025.
The curator decides which markets or adapters the vault may use, sets caps on each risk, sets fees and appoints the allocators who move funds day to day. Most changes that add risk must wait out a timelock first.
Yes. If a borrower's collateral falls in value faster than liquidators can act, the vault can be left with bad debt. The loss is shared across all depositors through a lower share price. In November 2025, a MEV Capital USDC vault realised bad debt of nearly 3.6% after the deUSD collapse.
In Vaults V2 a curator can charge a performance fee of up to 50% of the interest earned and a management fee of up to 5% of assets a year. Vaults V1 only have the performance fee. Fees are paid by minting new shares to the fee recipient.
Not always instantly. If borrowers have taken most of the liquidity, withdrawals wait. Vaults V2 offer an in-kind exit through forceDeallocate, with a penalty of up to 2%, unless a gate blocks it.
