## The two vaults

| Vault | Share | What it is |
| - | - | - |
| **USD\*** | USD\* | Perena's main (senior) vault |
| **USD\* Junior** | USD\* Junior | Higher-yield junior tranche: it takes losses before the senior vault does, in return for more yield. **Instant withdrawals pay a 1% exit fee** |

## Deposit

<Steps>
  <Step title="Open the vault">
    On **Farm → Lending / Single Assets**, click **USD\*** or **USD\* Junior** (Perena badge).
  </Step>

  <Step title="Enter USDC">
    Deposits are in **USDC** from your margin account (**Margin** shows the balance).
  </Step>

  <Step title="Read the details">
    Network, deposit amount, **Est. receipt received** (USDC ÷ share price), **Share price**, **APY** and projected monthly earnings.
  </Step>

  <Step title="Deposit">
    Click **Deposit** and approve. The shares arrive in your margin account.
  </Step>
</Steps>

## Withdraw

Switch to **Withdraw** and enter how many shares to redeem. The details show the **Est. USDC received**; for USD\* Junior that already includes the 1% instant-exit fee.

## The numbers

| Field | Meaning |
| - | - |
| **APY (7D)** | Perena's published APY |
| **Share price** | USDC value of one share. It rises as the vault earns |
| **Holders / Total Value Locked** | Perena's vault-wide figures |
| **Earned yield** | Your share-price gain since your first deposit |

Shares are valued at their share price in your health factor.
