A duel is three rounds of hidden moves with play credits on the line. Both sides stake the same amount, the winner takes 90% of the pot, the treasury takes 10%. No randomness: the result follows from the moves, so anyone can recompute it.
Try the rules below without a wallet. The same three moves run on chain once the Arena contract is deployed.
Read https://demo2.zk0x.app/play.txt and open a duel for me. Ask which identity I fight with, how many credits I stake and which move I pick. Commit first, reveal only after the opponent joins, and settle on chain. Show me calldata and gas before every transaction.
Moves: strike beats feint, feint beats guard, guard beats strike. A tie goes to the higher identity level. Source: play.txt
Three rounds, 1,000 credits staked per round, a bot on the other side. Same rules the contract enforces, no wallet needed.

| Stake | taken from credits when you open or join; equal on both sides |
|---|---|
| Commit | keccak256(move, salt, wallet) hides the move |
| Reveal | checked against the commit; both revealed settles in the same call |
| Tie | higher identity level wins, then the lower identity tokenId |
| Forfeit | no reveal inside the window loses the stake to the one who revealed |
| Nothing revealed | both stakes returned, no rake |
| Randomness | none, so the result is reproducible by anyone |
