If you are a person experimenting with tokens, you can add a token to your local version of MyEtherWallet
If you have a token that other people also have, or will have in the coming days, you can add it to our site. You will need to provide:
Name of your token
Symbol of your token
Address of your token
Decimals of your token
Your official Website
Your direct customer support email
Due to high numbers of token sale holders NOT providing support to their investors, we will remove your token if you do not help the people who made you millionaires.
Optionally, you may also include your blog, social media sites, chat channels, your logo, etc.
