Morpho is a lending protocol built from many small, separate markets, each pairing one loan asset with one kind of collateral. Lending into those markets one by one means choosing which collateral you are willing to be exposed to and moving funds when rates change. A Morpho vault does that for you. You deposit
into the vault, and its curator spreads it across the markets it has approved and moves it as rates and risk change.

How A Vault Works

Morpho vaults follow the ERC-4626 vault standard. When you deposit, the vault mints you shares. The interest the vault earns raises what each share is worth, so the number of shares you hold stays the same while the
they redeem for grows. There is nothing to claim.
The curator matters most. It decides which collateral the vault lends against and how much goes to each market, within limits the vault's contracts enforce. Different vaults for the same asset can carry very different risk. The vault in the plug below is Gauntlet USDC Prime on Base, curated by Gauntlet, which held about $400 million when this was written.

Depositing By Hand

  1. Get
    on Base and a little
    on Base for gas.
  2. Open Morpho's app, switch to Base, and pick a
    vault. Read which markets it lends into and who curates it.
  3. Approve the vault to move your
    , then deposit.
That is two transactions in most wallets: the approval, then the deposit.

Deposit With Plug

Use in App
The plug does it in one run on Base:
  1. Deposits 30
    into Gauntlet USDC Prime. Change the amount to whatever you want to lend.
  2. Shows you how many vault shares the deposit minted.
The approval happens in the same run and is sized to exactly the amount you deposit. The shares go to your wallet, the same as depositing through Morpho's app, so you can withdraw from either place.
To use a different vault, swap the vault in the plug for any other ERC-4626 vault on Base that takes
.

What It Costs

Depositing and withdrawing are free in Morpho itself. A vault's curator can take a performance fee out of the interest it earns; Gauntlet USDC Prime's was zero when this was written, and the rate a vault shows is after its fee. Base gas for the run comes to about a cent at November 2026 prices.

Getting It Back

Withdrawing burns your shares for
at the current share value. The vault has to pull that
out of the markets it lends into, so a withdrawal can wait if those markets are almost fully borrowed. The redeem and withdraw actions both exit a vault: one by share count, the other by amount.
