pump.fun vs Uniswap

pump.fun is a launchpad on Solana that lets anyone create a token and make it instantly tradeable in one click, for free. Famous for powering the memecoin boom, pump.fun has launched millions of tokens and has become a major driver of activity on Solana. Coins can also 'graduate' to decentralized exchanges, making pump.fun the ground zero for rapid token creation and trading.

Uniswap V4 rebuilds the protocol as a ‘Singleton’ contract and introduces programmable ‘hooks’ that let pools execute arbitrary logic before and after swaps. The redesign cuts gas costs by 15‑25 % and should open the door for new order types like TWAMMs and on‑chain limit orders. V4 is expected to go live shortly after Ethereum’s Pectra upgrade, when core devs will freeze the code under a Business Source Licence.
