NAS coin-swapping channel is opened, which means there are two NAS deposit addresses. If you have old NAS coins (the Nebulas 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 NAS coins (the Nebulas coins based on NAS main chain), you can directly view by clicking on the "Deposit" button.

Here’s an illustration for deposit of NAS coins:

If you have old NAS coins at HTX Pro, we will automatically swap them for new NAS 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 NAS coins to HTX Pro as soon as possible.
