From challenge to payout — stake USDCx on any prediction, duel opponents head-to-head, and winner takes all.
How It Works
Write a yes/no prediction question and stake USDCx on your answer. Set any amount above the minimum.
Your duel goes live for anyone to accept. An opponent must stake the same amount betting the opposite outcome.
When the prediction resolves, the winner receives the entire pot minus a small 5% protocol fee.
Features
All duels are settled in USDCx — bridged USDC from Ethereum via Circle's xReserve.
Winners receive their payout immediately when a duel resolves. No delays.
Track your consecutive wins and climb the leaderboard for bragging rights.
Every duel, win, and payout is recorded permanently on-chain.
DuelFi doesn't bet against you. Only a 5% fee funds protocol development.
