To make deposits and withdrawals from any anchored token you will first need to open a trustline with that token. Generally, StellarX will automatically make a trustline when you go through the standard deposit process (assuming you have the required XLM to be put in reserve).
1. Follow This Link to your network settings
2. You will see all of the open trustlines here, at the bottom of the page click 'Open Trustline'
3. You will need to input the token issuers Public Key, the currency it is representing as well as the Name of the token
4. Click 'Enter'
5. If you have 0.5 XLM available the trustline will be opened
If you do not have enough XLM available to put into the reserve, you will need to either fund your account with more XLM or trade some existing assets for XLM to top up your balance. For more information on how to fund XLM please see This Link.
