Mystery Box

How it works

Each Mystery Box gives you 1 open.
Open boxes to win testnet USDT rewards.
Rewards are credited straight to your wallet balance.
Results are provably fair and based on a hash + server seed.

Sign in required

Log in with your Nomisma account (same as quests / profile) so we can call the mystery box API on your behalf.

Mint open rights

Pay on Arbitrum to mint Soulbound mystery box tokens. Remaining opens in stats follow on-chain balance.
