The Rockefeller allows token issuers to permissionless-ly add their token onto the bridge platform. As a token owner who wants to take their token cross chain there is a condition that must be fulfilled to be able to do this automatically. The token must be an ownable, where you are the
owner() of the token or an approval has been granted by you for the token to be added to bridge. If any of this condition is passed, a user can now add a token to bridge.
