1Qualify. A coin enters the queue once its arena vault holds 0.05 SOL of pump.fun creator fees.
2Fight. Every 60 s the King meets the #1 challenger. Fees earned during the round shift the odds.
3Odds. P(King) = King fees ÷ (King fees + Challenger fees), frozen at 00:05 by an on-chain memo that also commits to a secret seed.
4Settle. The roll hashes that seed with a Solana block produced after the lock, so nobody can pick it. 100% of the loser's vault buys the winner on pump.fun / PumpSwap, and every token bought is burned.
5Verify. Each settled duel has a verify link in its match history: it recomputes the roll from the lock memo, the block and the revealed seed.
