Pumpfun made Pump Bridge the default route for cross-chain trades in its app on Oct. 21, 2026, replacing Relay. The platform says internal tests showed buys execute about twice as fast and produce 92% fewer errors, with Relay’s error rate above 10% and Pump Bridge’s below 1%. Pumpfun said a typical trade took around four seconds on Relay, while more than 10% took longer than seven seconds. The company is optimizing toward a theoretical fastest buy time of about 1.1 seconds, which is a target rather than a current result. Pump Bridge currently adds no bridging fee. Pumpfun added cross-chain swaps in May 2026, initially routing them through Relay, after launching on Solana in January 2024. The service supports trading across ecosystems including Ethereum, Base and BNB Chain. User complaints about latency and execution quality prompted the move to in-house infrastructure, according to the research findings. Rival FOMO continues to use Relay. Earlier Pumpfun descriptions characterized the error reduction as 12 times fewer errors and said randomized testing showed better fills; the latest figures are attributed to the company’s internal tests. The claims have not been independently verified in the supplied material.
