You asked to unstake a small amount, or a portion of your stake, and your wallet is asking you to approve something that looks much bigger than what you requested.
For example, unstaking 1 SOL from a 40 SOL position can produce an approval screen like this:
Withdraw 39.00868
Deposit into another staking account
Allow an unknown wallet address to withdraw 40.00868 SOL
The exact wording depends on which wallet you use, but the shape is the same: amounts larger than you asked for, a deposit into another stake account, and an address you do not recognise.
This is normal for an instant unstake from a native staking position, and you were right to stop and check. Here is what each part is.
Why the Amounts Look Bigger Than Your Request
Solana stake accounts are handled as whole units. If your 40 SOL sits in a single stake account and you ask to unstake 1 SOL, the transaction has to involve that whole account: the portion you asked for goes to the buyer, and the remainder is placed back into a stake account that is still yours.
The large numbers are the account being handled, not the amount you are giving up.
Why It Deposits Into Another Stake Account
That is your remaining stake going back into a stake account you own. It stays delegated and keeps earning. Nothing is being moved away from you.
Why an Unknown Address Appears
Instant unstake pays you immediately instead of making you wait an epoch. For a native staking position, it does that through a marketplace of liquidity providers who take over your stake and send SOL back.
The unfamiliar address is the liquidity provider buying your stake. Your wallet has no way to know who that is, so it displays it as unknown. The exchange happens in a single transaction, so either every part completes together or none of it does. There is no moment where someone holds your stake without you having been paid.
What Actually Happens to Your SOL
You receive the amount you asked to unstake, at the quote shown in the app.
The rest stays staked and keeps earning.
Nothing grants anyone ongoing access to your wallet. The approval covers that transaction only.
Before approving, check the estimated SOL you will receive shown in the Marinade app. That figure is the one that matters, not the internal amounts your wallet lists.
This Applies to Native Positions
Instant unstake works differently for mSOL. There it is a swap from mSOL to SOL routed through decentralized exchanges, so no stake accounts move and you will not see this screen.
Delayed Unstake Looks Different
If you use Delayed Unstake, your wallet shows an ordinary confirmation instead: the network fee, and no unfamiliar address. Even when you unstake part of a position, you will not see the withdraw-and-redeposit steps described above.
There is no buyer and no exchange, and it is free for Marinade Native, Select, and Recipes.
Your wallet may also show a small amount of SOL beyond the network fee, around 0.003 SOL. That is the amount needed to create the unstake request.
Delayed unstake is a two-step process. Your SOL does not return to your wallet on its own. Your stake deactivates over about one epoch, and then you must come back to the Marinade app and claim it. Until you claim, the SOL stays in the unstake position and will not appear in your wallet balance.
When You Should Cancel
The screen above is expected only because you started an unstake yourself. Cancel immediately if any of these are true:
You did not start the transaction.
You reached the site from a link, DM, email, or airdropped token rather than typing the address yourself.
The site is not app.marinade.finance. Check the address bar carefully.
You are being rushed, or told your funds are at risk unless you sign.
FAQ
Q: Will I lose the rest of my staked SOL?
A: No. Only the amount you asked for is unstaked. The remainder returns to a stake account you own and continues earning.
Q: I cancelled. Did anything happen?
A: No. A cancelled transaction does not execute, and nothing changed. You can start again whenever you are ready.
Q: Can that address take more later?
A: No. The approval covers the single transaction you sign. It does not grant ongoing access.
Q: I used delayed unstake and my SOL has not arrived.
A: Check whether you have claimed it. Delayed unstake does not send SOL back automatically; once the epoch completes, return to the app and claim. If the countdown has not finished yet, it is simply not ready.
Q: Why does delayed unstake not show this?
A: Because there is no buyer involved. Your stake deactivates over an epoch and you claim the SOL afterwards.
