Get started
Sign in and your wallet
You need an email address or a Google account. That's all.
Add USDC
Ultramint runs on Base. Your wallet holds native USDC on Base, and that's the only thing you need to trade.
Make your first Buy
You buy shares in the outcome you think will happen. Each winning share pays $1, less a small settlement fee.
Swipe
Swipe shows you one market at a time, as a card. Make your calls fast, then buy them together.
Withdraw
You can send USDC from your balance to any address on Base, whenever you like.
Your portfolio
Your portfolio shows everything you hold, everything you've earned, and what's waiting to be paid.
