How do I submit a prediction?

Connect your wallet on the Matches page, select a match before kickoff, choose your predicted outcome (Home / Draw / Away), and sign the message with your wallet. Your prediction is locked once kickoff passes.

What is XP?

XP (experience points) are earned for correct predictions. XP determines your leaderboard rank and streak. XP has no monetary value — it is purely an in-app score.

Why do I need to sign a message?

Wallet signatures prove you own the wallet address making the prediction. No private key is ever shared — only a signed message. This is standard EIP-191 signing, the same mechanism used across Web3 apps.

My prediction shows as pending — is that normal?

Yes. Predictions stay pending until the match result is settled by the admin. Settlement happens after the final whistle. Check back after the match ends.

Which wallets are supported?

Coinbase Smart Wallet, Base Account (ERC-6492), and any standard EOA wallet (MetaMask, Rainbow, etc.) on Base mainnet.

Is PrediXI available on mobile?

Yes. PrediXI is optimised for mobile and works inside Base App and Coinbase Wallet's in-app browser. Add it to your home screen for the best experience.

Is this a gambling app?

No. PrediXI is a sports prediction game. No real money is wagered or won. All rewards are XP points for in-app leaderboard ranking only.
