Pump.fun Adds Arbitrum Trading With Users’ In-App USDC Balance
The feature went live Oct. 28, letting users trade supported Arbitrum tokens without manually bridging funds.

Pump.fun has enabled trading for supported assets on Arbitrum using USDC already held in the app, letting users access the network without manually moving funds across blockchains.
The company announced the feature Oct. 28 and said Arbitrum trading was live. USDC is a digital token used to settle transactions.
The Arbitrum addition extends a series of network expansions. Pump.fun previously added OKX’s X Layer for in-app trading and enabled purchases of Monad and TON tokens through users’ USDC balances.
