We are creating a new token and want to see if our name we are thinking of using has been used before or is in use. How do we check this?
If you are using erc20 tokens then you can use this link
https://etherscan.io/search?f=0&q= then in the search bar, you can just input the name or abbreviation that you like for you token. Base on the results you can check whether that name has been used already or not.
You can also check here
https://coinmarketcap.com/ . Just go to search bar and there will be results once you will input the name that you like. If there are results meaning that name has been taken already.
