Pump.fun introduced Pump Bridge on Oct. 21, 2026, as a crosschain trading service and made it the default route for crosschain trades in its app after a randomized test. The company said a typical purchase took 1.95 seconds through Pump Bridge, compared with nearly four seconds through Relay, and that failed-buy rates were 0.9% and 11.2%, respectively.
Pump.fun also said the gap between spot prices and tokens received was about 17% smaller with Pump Bridge. Its test ran from Sept. 28 to Oct. 7, 2026; the speed and failure figures used separate sets of 383,326 trades and 416,669 outcomes, while the price comparison covered 35,333 completed USDC purchases worth up to $500. Pump.fun said it currently charges no additional fee to use the bridge.
