Challenging a claim
A challenge is a financial dispute backed by your own money. Win and you get the brand's stake. Lose and you forfeit yours.

How to file
1
Find the claim on the product page and click "Dispute this claim."
2
Select a reason code:
3
- Forged -- COA is fabricated
- Tampered -- COA altered (changed values, removed pages)
- Impossible value -- Amounts aren't physically plausible
- Wrong method -- Test method inappropriate for the compound
- Wrong product -- COA is for a different product or lot
- Outdated -- Results too old to represent current product
- Unverifiable -- Lab or COA cannot be confirmed
4
Provide evidence. Be specific: competing lab results, links to the lab's database, documentation of the problem.
5
Stake USDC. Minimum 50% of the brand's stake. Locked until the arbiter rules.
6
Wait for ruling (typically 7 days). Three outcomes: challenge upheld (you win), rejected (you lose), or inconclusive (both lose 10%).
Only challenge with real evidence. This costs real money -- frivolous disputes lose your entire stake.
