Leaderboards
The Leaderboard ranks all PrediXI users by total XP. Two views are available: All-Time (career XP) and This Week (XP earned in the current 7-day window).
Leaderboard positions update in real time after each match settlement. Your position is always shown even if you are outside the top ranks — connect your wallet to see your standing.
Daily XI
Every day, build your Daily XI — an 11-player squad picked from a rotating pool of World Cup players. Spin through player cards to fill each position: GK, RB, CB, CB, LB, RM, CM, CM, LM, ST, ST.
Once all 11 slots are filled, submit your XI. After the day's matches complete, your XI is scored based on how your players performed. Top XI earns maximum XP.
Your Daily XI is saved locally and synced to your account when you submit. You can only submit once per day — choose wisely.
World Cup Hub
The World Cup Hubis PrediXI's dedicated section for FIFA World Cup 2026. Make tournament predictions: group stage results, knockout outcomes, Golden Boot winner, and special fun picks.
World Cup predictions are recorded on Base when submitted with a connected wallet, creating a permanent onchain proof. The WC Hub updates in real time as the tournament progresses.
