Swap exchanges one asset for another at the current prices in the order book. It uses your Spot wallet.

Open Swap in the top menu.
In You give choose the asset and enter the amount (Max uses your whole available balance). In You receive choose the asset you want. The arrows button swaps them.
Check the quote: Rate, Fee, Price impact and Minimum received (or Maximum spent).
If needed, change the Slippage tolerance: What are slippage tolerance and price impact?
Click Review swap, check the details and click Confirm.

The result is shown at once:

Swap completed: everything was exchanged;
Swap partially completed: part was exchanged, the rest stays on your balance;
Swap not completed: the price moved beyond your tolerance, nothing was spent.

If your funds are on the Funding wallet, the page shows how much is there and a Transfer to Spot button.

A swap is a limit order with immediate execution, so it appears in your order history, and the regular trading fee of your tier is charged: What fee is charged on a swap? Swap is available for pairs that have a market on Strade.
