Add Liquidity

1. Visit the Pool page, Click “Details” to access the liquidity page

2. Users can add bilateral or single-sided liquidity here.

You can add USDm or BUSD single-sided liquidity, or add USDm + BUSD liquidity.

Note: Users need to confirm permission from the wallet before adding liquidity.

3. Here, we are going to use adding USDm + BUSD liquidity as an example. After adding 1 USDm and 1 BUSD, we can see that the currency reserves changed.

Remove Liquidity

we can remove single-sided liquidity or combo liquidity:

1. Choose the percentage of the LP token

2. Choose the currency to receive

You can choose to withdraw token A or token B, or withdraw both (token A+ token B). Take USDm as an example, if you choose to receive USDm, that means you are going to withdraw your LP token to USDm.

3. Click the Remove Liquidity button

Note: Users will need to confirm the action after approving the permission in the pop-up window.


In the upper right corner of the window, users can set the slippage tolerance and transaction speed.

If the actual transaction slippage exceeds the user setting, the transaction will not be executed.
