While web-users can currently exchange virtual coins, fun tokens, loyalty points, etc., such exchanges are limited to same-origin tokens. For example, points of a game application are exchangeable only within that application. This disclosure describes techniques that utilize inline-frames to enable token exchange in a manner that is both cross-origin and zero-friction. The techniques enable users to securely and confidentially send cross-origin tokens in a single-step process as easy as clicking a like-button, without additional login or confirmation. The techniques enable websites and services to easily micro-monetize (or fun-tokenize) digital content and user activities on the web, thereby inducing a powerful network effect.
