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

Here’s an illustration for deposit of IOST coins:

If you have old IOST coins on HTX, we will automatically swap them for new IOST 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 IOST coins to HTX as soon as possible.
