Custom Source markets
A Custom Source market lets you name the source the result comes from. Use it when the answer lives somewhere Ultramint's standard sources don't cover, like your league's results page or your club's announcements.
Where you can mint one
Only in a private Town.
How it resolves
Fermah Kernel's AI judges resolve it from the source you named, by the rule you wrote. The source and the rule are locked when you mint, like every market.
The rules on your source
- You can't name a source you control or can edit in order to decide the result.
- You can't change, fake or manipulate the source after you mint.
A market that breaks these rules can be voided. See the Market Creator Agreement and the Acceptable Use and Prohibited Markets Policy.
What buyers see
Every Custom Source market shows a warning: a source the creator controls could be used to fake the outcome. Buyers should check the source before they buy.
