2. Input the Token name or contract address in the box at the top of the page, then select the token you want to add, click "Add"
Tips: Because the Token name may be the same, so please carefully check the contract address when adding tokens
3. When you added it, please go to the "Assets Management" page, check the switch button open or not.
4. Finally, back to the assets page, you will see the token in the list.
PS: If you cannot find the token when searching, Please click here to submit the information.
