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. How your position is arranged does affect how a rebalance is handled, and that can affect what you earn over time.
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.
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: The number of accounts does not matter. The size of your position does, because it decides how much of your stake is affected when Marinade moves stake away from a validator that is underperforming.
With 100 SOL spread across ten accounts, a move affects one of them. The other nine keep earning, so about a tenth of your stake pauses for one epoch.
With 1.5 SOL in a single account there is nothing to spread, and an account under 2 SOL cannot be split. The whole position moves and none of it earns for that epoch.
Same event, very different cost. That is why a larger position tracks the displayed APY more closely.
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: Splitting and merging during a rebalance can leave individual accounts below 1 SOL. That is normal. Those accounts keep earning, and the program merges them into others later, so nothing is needed from you.
A whole position under 1 SOL is different. You can no longer stake less than 1 SOL, but a position staked before that restriction was added shows as Not active with a Not earning label, because the position itself is below Solana's minimum delegation. Stake more to bring it above 1 SOL, or unstake it.
Q: Does this apply to mSOL?
A: No. Marinade Liquid gives you a single mSOL token balance instead of stake accounts.
