To open a margin position, go to the Nolus app and connect your non-custodial wallet: Solflare or Phantom. A Solana wallet signs everything on Nolus for you, so you do not need a second wallet. Before you connect anything, the app shows the Solana catalog.
Open the Margin section from the left-hand navigation, then click Open Position.
Configuring the position
You are taken to a form where you set up the position.
Choose the position type. Long (Buy) is for an asset you expect to rise. Short positions are currently available on Solana.
Select the asset you are putting up as Collateral, your down payment. On Solana that is SOL and USDC. Your available balance is shown, and you enter the amount you want to commit.
Choose the asset you want exposure to. On Solana you can go long on cbBTC, HYPE, SOL and wETH.
Adjust the Leverage slider to set how much you borrow on top of your collateral. It offers the available steps and starts at the maximum, up to 5x.
As you change the parameters, the transaction details update in real time: total position size, estimated interest, liquidation trigger and price.
Every position also has a minimum and a maximum down payment: on Solana the minimum is $40 and the maximum depends on the asset you are buying. If your amount falls outside the range, the form shows you the live limits before you can continue.
Confirming
If everything looks right, click Open Position and confirm the transaction in your wallet. Opening usually takes less than a minute. On Solana a position is typically live in about 20 to 25 seconds.
What happens behind the scenes
Your collateral and the borrowed funds buy the asset you chose through an integrated exchange aggregator on Solana. The funds first move between your Nolus account and Solana over the protocol's transfer channel. Once the transaction confirms, your position is live and visible in the Margin section of the app.
If a step cannot complete, the position is never left half open. The app shows Position Opening Failed and confirms that the protocol has refunded your funds to your wallet: your down payment comes back and the borrowed amount is returned to the pool in the same transaction, so you can simply try again.
