You trade perps on Legend using your Arena Balance as starting capital. Every position you open and close updates your PnL in real-time — and your opponent can see it. The goal is simple: end the match with a higher PnL than the person across from you. Account balances sync on-chain throughout.
When time runs out, the match is over. Final PnL is captured, the winner is determined, and the prize is deposited into the contract. You withdraw your winnings directly — no waiting, no middleman.
