Decentralized exchanges like Hyperliquid and PumpFun are implementing token buyback strategies to enhance the value of their native tokens. Hyperliquid's $HYPE token benefits from a model where trading fees are used to repurchase tokens, directly linking exchange volume to token demand. Similarly, PumpFun's $PUMP token sees regular burns funded by a portion of platform revenue, aligning token supply with platform success. These buyback mechanisms aim to create a transparent connection between platform usage and token flow, potentially increasing token value and investor interest.
