Now you are ready to test any of the FXPools by adding liquidity and swapping tokens. On this tutorial, we will test adding liquidity to the PHPT-USDC pool and swapping PHPT to XSGD.

Add Liquidity

Add liquidity to the PHPT-USDC pool using "two-sided" deposit.

1. Go to the pool page
2. Use the network switcher on the upper right portion of the site to connect to "Sepolia"

3. Select PHPT/USDC pool and click Manage

4. Select the Add Liquidity tab

5. Take note - this screenshot illustrates adding liquidity at the 50:50 LP ratio (that looks like the FX rate), however please note that this ratio may change.

   
6. Enter the amount of liquidity you’d like to provide and choose the amount of slippage tolerance

7. Click "Supply" button

8. Add Liquidity Details window will pop up, click "Confirm Supply"

9. Confirm the transactions from Metamask

Swap

Swap PHPT to XSGD.

1. Go to the swap page
2. Use the network switcher on the upper right portion of the site to connect to "Sepolia"

3. Select "PHPT" from the "from" token

4. Select "XSGD" from the "to" token

5. Input the swap amount

6. Click "swap" button

7. Confirm the transaction from Metamask.

You can click on the cog icon to open the "Transaction Settings" window to set Slippage Tolerance and Transaction Deadline settings.
