IOST coin-swapping channel is opened, which means there are two IOST deposit addresses. If you have old IOST coins (the IOST coins based on the ERC20 technology), you need to click on "Deposit to the Old Address" to view the deposit address; if you have new IOST coins (the IOST coins based on IOST main chain), 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 at Huobi Korea, 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 Huobi Korea as soon as possible.
