# Deposit and withdraw

> Deposit USDe into MolQ on Mantle and redeem your mqUSDe shares.

## Prerequisites

* A wallet supported by the MolQ application.
* Mantle mainnet configured in your wallet.
* USDe on Mantle.
* MNT for transaction gas.

<Steps>
  <Step title="Open the MolQ app">
    Visit [app.molq.site](https://app.molq.site), connect your wallet, and switch to Mantle
    mainnet when prompted.
  </Step>

  <Step title="Enter a deposit amount">
    Open **Deposit**, enter the amount of USDe, and review the current vault allocation and
    variable APY inputs.
  </Step>

  <Step title="Approve USDe">
    When your allowance is insufficient, sign the USDe approval transaction. This permits only
    the MolQ vault to transfer the amount you approve.
  </Step>

  <Step title="Deposit">
    Sign the vault deposit transaction. The ERC-4626 vault transfers USDe, mints `mqUSDe`, and
    supplies the target shield allocation to Aave.
  </Step>

  <Step title="Verify the position">
    Check your `mqUSDe` balance in the app and open the transaction link on Mantlescan.
  </Step>
</Steps>

## Withdraw

Select **Withdraw all** in the app and sign the redemption transaction. If the
vault does not hold enough liquid USDe, it withdraws the required assets from
Aave before returning USDe to your wallet.

<Info>
  Deposits and withdrawals do not depend on an AI decision. They are direct ERC-4626 contract
  calls and remain available while the required onchain liquidity exists. Deposits are disabled
  when the vault is paused; withdrawals remain available.
