Claims live in Command Center, under Rewards and claims, for the wallet that earned them. Check that you have connected the right wallet and picked the right chain. League, airdrop, recruiter, battle and creator payouts are listed there once they are ready.
A reward that is still Pending is not claimable yet. Prizes are not paid automatically to every holder and are not guaranteed. For an imported coin, creator earnings can only be claimed after you prove you own the coin.
