USDC Vault withdrawals are instant and there is no lockup.
The yield your deposit earns compounds into your balance automatically, with nothing to claim and no action needed from you. Bonus rewards from campaigns are the exception and have to be claimed manually.
Withdrawing Your USDC
Go to app.marinade.finance and connect the wallet you deposited from.
Open Portfolio and find your USDC vault position under Earn positions.
Open the ⋯ menu on that row and choose Withdraw. The row's own button is Deposit, so Withdraw sits in the menu beside it.
Enter the amount you want to withdraw, or click Max to withdraw the full position.
Click Withdraw and approve the transaction in your wallet. The USDC arrives in your wallet once it confirms.
Keep a small amount of SOL in your wallet to cover the network fee, even though you are withdrawing USDC.
The Withdraw now label with the lightning icon is there to confirm that the withdrawal is immediate. There is no choice to make: the USDC Vault has only one withdrawal mode, and no delayed equivalent to unstaking SOL.
Claim Your Bonus Rewards First
There are two different things earning in your position, and they behave differently:
Vault yield accrues automatically into your USDC balance. Nothing to claim. It is already included in the amount you withdraw.
Bonus rewards from campaigns are separate and must be claimed manually.
On the My position tab, look for a line reading "You've earned ... in bonus rewards" with a Claim all button. Claim these before withdrawing your full position, so you do not leave rewards behind.
FAQ
Q: Is there a withdrawal fee?
A: Marinade charges no deposit or withdrawal fee. The 5% performance fee applies only to the net interest your position earned, and it is already reflected in the APY you were shown.
Q: How long does it take?
A: One transaction. There is no waiting period, no epoch to wait for, and no delayed option. The USDC Vault does not follow Solana's staking epoch cycle.
Q: Do I need to claim my yield before withdrawing?
A: No. Vault yield is already part of your balance. Only campaign bonus rewards need claiming, and only if you have any showing as pending.
Q: Do I unstake USDC the same way I unstake SOL?
A: No. USDC is not staked SOL. It is withdrawn from the Earn section, not through the SOL unstake flow, and it is not subject to the epoch timing that applies to staked SOL.
Q: Where did my interest go?
A: Into your USDC balance. The vault compounds interest into the position rather than paying it out separately, so the balance you withdraw already includes it. Your My position tab shows the balance, estimated value, and total rewards earned.
If You Cannot Find the Withdraw Option
Look in the ⋯ menu, not on the row. The USDC vault row's own button is Deposit. Withdraw is in the menu next to it.
Check the connected wallet. The address in the top right must be the one that deposited. A different wallet shows no position, and no way to withdraw from it.
Check you still have a position. If the balance is zero there is nothing to withdraw and the option does not appear.
Reload and reconnect. Refresh the page, disconnect your wallet, and connect again.
On a phone, there are no extensions to disable. Update your wallet app, then reload and reconnect.
On a desktop browser, try a private window with only your wallet extension enabled, in case another extension is interfering.
If it is still missing, your funds are not stuck. The vault is built on Kamino's lending market, so you can withdraw the same position directly on Kamino at any time. Contact us as well, with your wallet address, a screenshot, and whether you are on desktop or mobile.
Does my location affect this? No country is restricted at the moment. If that changes in future it would show as the app being unavailable to you, not as a single button disappearing, so a missing Withdraw option is not a location problem.
If a Withdrawal Does Not Go Through
Your USDC is supplied to Kamino's lending markets, so withdrawals depend on liquidity being available there. This is rare, but during periods of very high utilization a withdrawal can be constrained.
If your wallet or a block explorer shows the withdrawal as confirmed but the USDC has not shown up, see My Transaction Confirmed But My Position Is Not Showing.
Try a smaller amount, or try again shortly. If it persists, start a conversation with us. The app lists this as Liquidity risk under Strategy overview.
Want your funds immediately and can't wait for a reply? The USDC Vault is built on Kamino's lending market, so your position is the same one visible on Kamino directly. You can withdraw there any time without waiting on us.
