PUMP.RPG is a Solana-based gaming and betting platform built around the pump.fun ecosystem. Players can roll persistent heroes whose combat attributes are influenced by their real pump.fun trading activity, including realized PnL, trading volume, win rate, trading frequency and followers. Heroes are automatically deployed into an eight-player free-for-all arena where deterministic combat simulations determine the finishing order. The arena also functions as a pari-mutuel betting market. Anyone with a Solana wallet can wager on participating heroes, with betting pools settled according to the final fight outcome. A portion of each betting pool is distributed to winning bettors, the winning hero owner and the PUMPRPG ecosystem through a buyback-and-burn mechanism. $PUMPRPG is the native token of the ecosystem. It launched through pump.fun as a fair-launch token. Planned utility includes governance and token sinks associated with hero upgrades, runes and loadouts. PUMP.RPG is designed to combine on-chain trading reputation, autonomous combat and crypto-native betting into a persistent gaming experience.
