Yes. Slingshot passes on any positive slippage back to you.

When you place a swap, the price of the asset can fluctuate from the time you place your order to the time it is executed. This is known as slippage, and the reason why orders will often fill above or below 100%. You can set the Max Slippage of an order when placing a swap.

Slippage occurs in all types of markets and is not unique to crypto. While other applications may keep any positive slippage (additional profit from the swap due to price fluctuations), Slingshot passes on any positive slippage back to you. If your order completes at a fill rate above 100%, you have received positive slippage.

You can see your fill amount for any swap in your Order History section at the bottom of swapping page window. In addition, the order completion form will show the fill rate of a completed swap.

Setting a maximum slippage limit guarantees a minimum return for the swap that needs to be met in order for the swap to execute, otherwise the transaction will be rejected and you will lose your transaction fee.

For instance, if you wanted to buy 1.00 WETH for 4,250 USDC and set the max slippage at 1%, then the swap will only execute when the order is picked up by the network if at least 0.99 WETH can be received. If this threshold cannot be met, then the order will be rejected and the funds will be sent back to your wallet, minus gas fees.
