I can't find the place to add token wallet. Can you find the relevant information about the key and other token in the block browser?
You have to first register in order to buy the tokens and the pre-sale starts on June 05 '2018.
You should have ERC20 compatible token wallet (MEW, Metamask,.....) to add the ETH Travel Tokens. We have also published the same in our website. Please visit our website at
https://ethtravel.io for more information and do let us know if you have any further questions.
