Pump.fun pivots to internal infrastructure with launch of Pump Bridge

The platform’s internal data, gathered between September 28 and October 7, highlights a stark performance gap between the two services. Pump Bridge completed transactions in an average of 1.95 seconds, nearly twice as fast as the 3.88 seconds recorded by Relay. Reliability metrics proved even more pronounced: Relay suffered an 11.2% failure rate on buy orders, whereas Pump Bridge maintained an error rate of just 0.9%. Based on these findings, a user executing 10 daily trades would encounter a failure once every 11 days on the new system, compared to more than one daily failure under the previous setup.

Beyond speed and uptime, the company reported improvements in execution pricing. Analysis of USDC transactions under $500 showed a median execution gap of 3.0% for Pump Bridge, compared to 3.6% for Relay. Pump.fun projects that a trader making 10 daily $500 buys could theoretically save $11,000 annually due to these tighter price executions. While Pump Bridge currently carries no additional bridging fees, the company continues to levy a 0.45% trading fee on transactions from wallets without referral codes. To support these claims, Pump.fun has committed to making its underlying experimental datasets public for independent review.
