This directory shows tokens that are minted. Another criteria for tokens to be shown is permission from the token creator to be publicly listed here. BSVTokens.net reserves the right to not display certain tokens, such as those that have negative qualities (e.g. promoting racism).
Have you created tokens? To get your tokens listed here, first visit main page to give authorization to read your token details. Then go to 'Show my tokens', and after that click 'Modify', and put a checkbox to 'Allow token listing on BSV Tokens website'.
