ONT coin-swapping channel is opened, which means there are two ONT deposit addresses. If you have old ONT coins (the Ontology coins based on the NEP-5 technology), you need to click on "Deposit to the Old Address" to view the deposit address; if you have new ONT coins (the Ontology coins based on ONT main chain), you can directly view by clicking on the "Deposit" button.
Here’s an illustration for deposit of ONT coins:
If you have old ONT coins at Huobi Korea, we will automatically swap them for new ONT 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 ONT coins to Huobi Korea as soon as possible.
