Pump.fun, a popular Solana-based memecoin launchpad, is reportedly testing its in-house automated market maker (AMM) that could replace Raydium as the default decentralized exchange for graduated tokens. The platform aims to capture more fees and keep liquidity within its ecosystem. This shift could also lead to the introduction of memecoin perpetuals and lending. If Pump.fun moves forward with the transition, Raydium could experience a significant drop in trading volume, impacting its market position. Additionally, Pump.fun recently blocked a hacker connected to the $1.4 billion Bybit hack from laundering funds on its platform.
