18C coin-swapping channel is opened, which means there are two 18C deposit addresses. If you have old 18C coins ("18T" based on ERC20), you need to click on "Deposit to the Old Address" to view the deposit address; if you have new 18C coins, you can directly view by clicking on the "Deposit" button.

Here’s an illustration for deposit of 18C coins:

If you have old 18C coins on HTX, we will automatically swap them for new 18C coins, so you don't have to take any action or worry about any loss of your assets. To avoid loss of coins, phishing and other consequences that may be caused by your chain-swapping and to ensure security of your assets, it is recommended that you deposit the old 18C coins to HTX as soon as possible.
