According to EricCryptoman, the Pump Fun of $SUI, supported by the Sui Foundation, is now live and features a significant mechanism where 50% of platform fees are allocated to buying back and burning the $HIPPO token (source: EricCryptoman on Twitter, May 20, 2025). This initiative is designed to reduce circulating supply, creating a potential supply shock that traders should closely monitor. The aggressive buyback and burn model could lead to increased volatility and upward price pressure on $HIPPO, making this a crucial development for crypto market participants interested in high-momentum DeFi tokens.
