Request any matchup. Pledge to the pot. The winner takes the prize — or sends it to a charity they choose.
Pledges are public commitments — nothing is charged unless the matchup is booked and happens on Spar. The pot funds the winner's prize or their chosen charity. It is never a wager on the outcome.
