Trust Token API

Experimenting


You can manually enable this feature on your build of Chrome by using the "--enable-features=TrustTokens" command line flag; in order to execute Trust Tokens operations, you'll need an origin trial token present or to have provided the additional (...and unfortunately wordy) command-line flag --enable-blink-features=TrustTokens,TrustTokensAlwaysAllowIssuance. If you are experimenting with a new issuer, you can manually provide the Trust Token key commitments via the “--additional-trust-token-key-commitments=’{ "<issuer origin>": <key commitment response> }’” flag.


Process for registering as an issuer: https://docs.google.com/document/d/1cvUdAmcstH6khLL7OrLde4TnaPaMF1qPp3i-2XR46kU/


If you are trying to register as a developer to use the Trust Token APIs to issue/redeem, please follow the standard Origin Trial registration process: https://github.com/GoogleChrome/OriginTrials/blob/gh-pages/developer-guide.md
