Pump.fun has launched a significant upgrade to its app, enabling frictionless multi-chain trading across Ethereum, Base, and BNB Chain. Announced on May 26, the new feature allows users to trade assets directly on multiple EVM chains using a single wallet, eliminating the need for cross-chain bridges or native gas tokens. Solana will serve as the settlement and gas subsidy layer, enhancing the trading experience. The upgrade aims to simplify cross-chain operations by automatically generating multi-chain wallets for users, facilitating seamless access to assets across different EVM ecosystems. This development is expected to help users more effectively capture cross-chain market opportunities, according to the Pump.fun team.
