Skip to main content
Earn is the Base USDC yield page in o1 Terminal. Choose Earn in the navigation, or open o1.exchange/earn while Base is selected. The page subtitle is “Put idle USDC to work through Turnkey Earn.” The only asset is USDC on Base. The card is titled USDC on Base and names the vault provider, Aave or Morpho, together with the vault name. When more than one vault is listed, choose it from the selector in the card header. Earn is available only while Base is the selected network. Switching to another network leaves the page.
Net APY is not a promised return. The rate can change. Est. daily is calculated from the current Net APY and balance, and the page states that it is not a guarantee. Depositing moves your USDC into the Aave or Morpho vault named on the card. That vault carries smart-contract and counterparty risk. Earned this position and Lifetime earned can be negative if the position value falls.

Key properties

Base USDC

The only supported asset is USDC on Base.

Wallets created in o1

Deposit and withdraw with a Base wallet created in o1. Imported wallets cannot use Earn.

Withdraw at any time

There is no lockup or cooldown. If new deposits are paused, withdrawals stay open.

Sponsored gas

The Gas line reads Sponsored. A deposit still uses USDC that is already in the selected wallet.

​
What you see

The action card has Deposit and Withdraw. It shows Net APY when a rate is available. Fee is the current fee for the selected product. When the fee is zero or not set, the line reads None. Gas reads Sponsored. While the position value is above zero, the Position panel shows:
  • Current value: the USDC value of the open position.
  • Net deposited: deposits minus withdrawals for this position.
  • Days staked: how long this open position has existed, plus the date it started. Under one day it reads < 1 day.
  • Earned this position: current value minus net deposited.
  • Est. daily: an estimate prefixed with ~, from the current Net APY and balance. The value is marked “Estimated from current Net APY and balance. Not a guarantee.”
Lifetime earned is shown above those rows and includes the open position. A MAX withdrawal keeps that figure visible after the position closes. Before the first deposit, the panel reads Your balance and lifetime earned will appear after the first deposit. Activity lists deposits and withdrawals for the selected wallet and product. Filter by action (Deposit or Withdraw) and by status (Confirming, Confirmed, or Failed). When a transaction hash is available, the Tx column links to Basescan. An empty list reads Deposits and withdrawals will show up here.

​
Deposit

1

Open Earn on Base

Sign in and select Base. Choose Earn.
2

Select a wallet created in o1

Use the wallet menu and pick a Base wallet created in o1. Your main wallet is marked Main. An imported wallet shows Imported wallets can’t use Earn. Switch to a wallet created in o1.
3

Enter a USDC amount

Stay on Deposit. Balance is the USDC in the selected wallet. Enter an amount, or choose 25%, 50%, 75%, or MAX.
4

Confirm the deposit

Check Fee and Gas, then select Deposit. The banner names the amount and the steps Signed, Submitted, and Confirming on Base. You can leave and come back while it confirms. This wallet cannot start a second Earn transaction until the current one finishes.

​
Withdraw

1

Choose Withdraw

Select Withdraw. Balance switches to the current position value. The amount must be greater than 0 and no larger than that value.
2

Confirm the withdrawal

Choose 25%, 50%, 75%, or MAX, then select Withdraw. MAX withdraws the open position. Gas is sponsored, and the same confirmation banner appears. USDC is withdrawn to the selected wallet after the transaction confirms.
A pause on new deposits does not close withdrawals. The position panel reads New deposits are paused. Withdrawals stay open. The deposit card shows that same line while Deposit is selected. You can still withdraw when the product is ready and the current value is above 0.

​
When an action is blocked

Earn is separate from O Staking, which deposits O and returns wstO with no built-in yield. It is also separate from Launchpad staking vaults and from referral rewards.
