If you look at your wallet and find several Solana stake accounts rather than one, that is normal for Marinade Native. You do not need to do anything about them.
Why There Is More Than One
Marinade Native does not pool your SOL. You keep your own stake accounts, in your own wallet, delegated on your behalf. That is what makes it non-custodial.
Accounts appear and change for two ordinary reasons:
New deposits. Staking more SOL usually creates a new stake account rather than adding to an existing one.
Rebalancing. Marinade reviews validators every epoch and moves stake away from any that slip on uptime, commission, or performance. Doing that means splitting and merging accounts.
The Program Manages Them for You
Splitting and merging happens automatically as part of rebalancing. You are never asked to approve it, and you do not need to tidy anything up. The arrangement of accounts does not change what you earn.
Account size does affect how a move is handled:
Solana requires a minimum of 1 SOL per stake account, so an account under 2 SOL cannot be split into two valid parts and has to move as a single block.
With larger accounts, only the portion being moved is split off, and the remainder keeps earning without interruption.
This matters for small positions, because stake moved while it is still activating starts its activation period again. See I Deposited But Have No Rewards Yet.
You Can Manage Them Yourself, but We Suggest You Do Not
Because the accounts are yours, you can withdraw them directly from your wallet without using the Marinade app, and stake them again yourself afterwards.
Doing so carries no penalty, but there is no advantage either. Anything you restake goes through the same activation period as any new stake and earns nothing until it has been active for a full epoch. Our recommendation is to leave the accounts alone and let the program manage them.
Why This Design Is Worth the Untidiness
Holding your own stake accounts is the reason Marinade Native never takes custody of your SOL. If Marinade disappeared tomorrow, your stake would still be yours, delegated as it is, and you could withdraw it directly from your wallet without us.
The trade-off is practical rather than financial. In the unlikely event that the Marinade app is unavailable, unstaking a large number of accounts by hand is tedious, since you would be doing them one at a time.
FAQ
Q: Do multiple accounts reduce my rewards?
A: No. Rewards depend on how much SOL is staked and for how long, not on how many accounts it sits in.
Q: Can I merge them myself?
A: There is no need to. Merging and splitting is handled automatically during rebalancing.
Q: Can I close the small ones?
A: You can withdraw any stake account directly from your wallet, which closes it. Restaking afterwards restarts the activation period, so most people are better off leaving them.
Q: Why do I have an account holding less than 1 SOL?
A: You cannot deposit less than 1 SOL, but splitting and merging during rebalancing can temporarily leave an account below that. Those are eventually merged into other accounts, so it resolves on its own and needs no action from you.
Q: Does this apply to mSOL?
A: No. Marinade Liquid gives you a single mSOL token balance instead of stake accounts.
