Solana-based memecoin platform Pump.fun has updated its mobile app to make Pump Bridge the default cross-chain trading route. The shift, announced on October 22, follows a trial period that demonstrated faster transaction times, improved reliability, and better execution compared to Relay, which previously held the default position. While other trading charges still apply, Pump Bridge does not include a separate bridging fee.
During the trial—which ran from September 28 through October 7—Pump.fun assigned users at random to either Pump Bridge or Relay, with participants switching between the two routes multiple times. Unlike a public benchmark, this study exclusively tracked purchases within the mobile app’s environment and covered cross-chain transactions involving Robinhood, BSC, Base, Arc, and Ink. Following the test, Pump.fun transitioned its cross-chain orders to its proprietary infrastructure, while Relay continued to service other applications like FOMO.
Pump Bridge Cuts Buy Times and Transaction Errors
Pump.fun reported a median purchase time of 1.95 seconds via Pump Bridge, cutting the 3.88-second duration recorded by Relay roughly in half.
For the fastest 10% of transactions, Pump Bridge completed trades in 1.23 seconds, compared to 2.75 seconds for Relay. At the slower end, the bottom 10% of purchases took longer than 4.21 seconds on Pump Bridge and exceeded 7.36 seconds on Relay.
Reliability also showed significant gains. Relay registered an 11.2% buy error rate, whereas Pump Bridge dropped that figure to 0.9%, translating to a 92% reduction in errors based on the platform’s metrics.
Under these conditions, a trader executing 10 purchases daily would experience more than one failed buy every day on Relay. Conversely, the same trading pattern on Pump Bridge would yield approximately one failure every 11 days.
Better Execution Prices Drive Estimated Savings
Beyond speed, Pump.fun evaluated how many tokens traders received relative to prevailing spot prices, as rapid transactions can still yield fewer tokens than reference prices suggest.
For completed USDC purchases under $500, the median execution gap decreased from 3.6% on Relay down to 3.0% on Pump Bridge.
This reflects a roughly 17% reduction in the gap connecting market reference prices and actual execution. Consequently, users acquired a higher volume of tokens for the same capital outlay during the comparison.
Based on the assumption that the test’s execution differences persist year-round, Pump.fun estimated that executing 10 daily purchases of $500 each could generate approximately $11,000 in annual savings compared to Relay.
Although the platform levies no individual bridging fee for the new route, other trading charges remain active, such as a 0.45% per-trade fee for app wallets that lack a referral code.

Testing Limits and Wider Trading Expansion
The company’s findings encompassed order success and final token amounts rather than completion speeds alone. Pump.fun indicated it will make the underlying datasets available for external review, though independent testing across alternate trading environments has not yet verified identical outcomes.
Accounting for network communication and receiving blockchain confirmations, the company calculated a theoretical minimum purchase time of approximately 1.1 seconds. Its fastest recorded trades finished just 0.13 seconds shy of that projection.
Cross-chain trading was initially launched by Pump.fun in May. This latest integration shifts its mobile application away from a third-party default toward an in-house bridge for supported transactions. Additionally, the platform introduced a perpetual futures interface on October 17 through Hyperliquid, which handles execution, margin, funding, and settlement with published fees of 0.10% per order, alongside restrictions for users in the United States and Ontario.
In other developments, an October 20 report highlighted a Bitquery study revealing that 79% of sampled Pump.fun tokens experienced zero trading activity following their launch day. Pump.fun stated it intends to introduce further enhancements to Pump Bridge processing speeds.
Conclusion
Pump.fun has transitioned its mobile app’s default cross-chain pathway from Relay to Pump Bridge following a 10-day in-app trial that showed faster transaction speeds, fewer errors, and tighter execution gaps. The company plans ongoing improvements to the service, and existing app trading fees remain operational.
