In order to deposit liquidity on uTrade ICON, it must be done in TWO steps. This is because two tokens cannot be transferred at the same time within a smart contract on the ICON blockchain.
Deposit ICX. You will receive "Credits" in the amount of ICX you deposited. If you change your mind, you can withdraw your Credits back into your wallet as ICX. If you are satisfied, you may proceed to the next step.
Note: You will be able to see the Estimated Trading Token amount that will correctly balance the amount of ICX you would like to deposit. This is the maximum amount of trading token you would be able to deposit in Step 2.
Deposit the other side of the pair (i.e. the trading token). You can only deposit an amount of trading tokens that can be balanced by the amount of Credits you have. If you deposit less trading tokens, any remaining Credits will automatically be withdrawn and return to your wallet as ICX.
