Output Tags

WhatsOnChain tags recognized transaction outputs in every block. We also provide basic block stats around those tags, both in the API and on the Explorer website.

If you want your transaction outputs to be tagged, please reach out to us over email or in our Telegram channel with these details:

  • IDs of a few example transactions

  • Any pattern that could be used to detect your transactions with enough precision

  • Name of the protocol used for the data/script (if any)

  • Brand colors, for tag background and tag text

  • The logo file


  • A link to the webpage for your app, protocol, or token.

  • A short description of your app, protocol, or token.

After we've received this information, we can go and add the new tag to our system, which should be available from then on.
