You can reduce a margin position's debt in two ways: repay it with assets held in your Nolus account, or close part or all of the position and settle the debt from the assets already inside it. Both flows are guided in the app.
Repaying a position
Repaying lowers your risk, improves your leverage ratio, and moves you closer to owning the position's assets outright. From the position detail view, click Repay to open the repayment dialog. The Repay button on the position's row in Your Positions on Home opens the same dialog, and so does the Back to Healthy suggestion in the position's Health card, which fills in the amount that brings the position back to Healthy.
The repayment asset is set for you and shown beside Amount to Repay: it is the asset the debt is denominated in, USDC on a long position and the asset you shorted on a short one. Your Balance of it is shown on the right, and clicking it fills in your balance less the network fee.
Set the amount with the slider or the input field.
Review the preview. It reads You pay off followed by the debt it repays, Liquidation price moves to followed by the new price, and You still owe followed by the debt left. That price is the same nearest-liquidation figure the Summary shows, computed from everything you owe, so it moves as the debt falls. Repay the whole debt and the preview reads You pay off all followed by the debt instead of quoting a price.
Click Repay and approve the transaction in your wallet. A repayment settles in that one transaction, usually within seconds, and a Position Repaid toast confirms it.
Why repay
A partial repayment lowers your total debt, improving the health of the position and reducing liquidation risk.
A full repayment clears the debt entirely and gives you full ownership of the assets in the position.
Either way, repayment lets you adjust your equity ratio as market conditions change.
Closing a margin position
To settle debt using only the assets already held in the position, use the Close button, on the position detail view or on the position's row in Your Positions on Home. This partially or fully closes the position by selling part of it.
In the Close dialog, choose how much of the position's asset you want to use to repay the debt: the asset you bought on a long position, the stable it holds on a short one. The preview then shows:
If the amount leaves part of the loan, You pay off followed by the debt it repays, and You still owe followed by the debt that remains
If the amount repays the whole loan, You pay off all followed by the debt, and The position closes and you get back followed by what comes back to your account
Either way, the asset's live price and the swap fees applied by the exchange the position trades on
Click Close Position and approve the transaction in your wallet. Closing the whole position usually takes less than 30 seconds, and a partial close less than a minute.
Close scenarios
Full debt repayment, the Debt mark on the slider, sells just enough of the position at the live price to settle all outstanding debt.
A partial close sells a portion of the position to repay part of the debt, leaving the rest intact.
A full close ends the position entirely and, on a long position, lets you decide what to do with what is left, either keeping some of the leveraged asset or converting all of it to USDC.
What to expect on Solana
A partial close has to leave a workable position behind: the amount you close must be at least 0.5 USDC, and what remains has to be worth at least 15 USDC. The app tells you before you sign if your amount breaks either limit. A full close is exempt from both, so you can always exit completely.
A close moves assets between your Nolus account and Solana over the protocol's transfer channel and trades there, so it takes a few steps. It normally completes in under a minute, occasionally a few minutes if the trade has to be retried at a better price. While it runs, the position page shows a Position Now Closing alert, or Closing Part of the Position for a close that leaves part of the loan, with its steps. Once a close that ends the position pays out, the position leaves Your Positions, and if you are on its page the app takes you back to Home; its record stays in Activities. A repayment settles in your own transaction and shows no such steps.
Both transactions are prepared by Nolus for you and checked before your wallet is asked to sign, so both need the Nolus app to reach its backend. If it cannot, the dialog reports an error rather than handing you something to sign. Reload the page and try again.
Proceeds are paid to your Nolus account, and you can withdraw them to your Solana wallet with Withdraw in the Account popover, which opens from the wallet button in the top bar. Repaying and closing stay available for as long as the position exists (except while another operation on it, or a Market Anomaly Guard hold, is running), even if Nolus has stopped offering that asset or protocol to new positions.
