Create a campaign
Set your name, your cards and your prizes. When you're done, SCRATCH mints your unique
link and QR code — that's the page players open to connect their wallet and scratch.
Live campaigns require at least 100,000 SCRATCH.
For now, local test mode lets you build and play a campaign without a wallet or funds.
Campaign setup
Live campaigns lock funds in a smart contract. Local tests simulate the same odds without moving tokens.
