Pump.fun co-founder and COO Alon said on X that the platform’s in-house cross-chain bridge, Pump Bridge, is now available to all app users. Based on test data he shared, Pump Bridge delivered roughly 2x faster buy execution than Relay, the third-party bridge service previously used by the platform. He said the transaction error rate dropped 92%, falling from more than 11% to under 1%, while the same amount of capital on average received more tokens. He also said the bridge currently charges no extra cross-chain fee.
According to Alon, Relay previously saw about one failed transaction for every nine cross-chain buys. A typical trade took close to four seconds, and about 10% of transactions took more than seven seconds. He added that the social trading app FOMO is still using Relay. The results came from randomized tests run between Sept. 28 and Oct. 7 across Robinhood, BSC, Base, Arc and Ink, excluding Ethereum. The dataset covered 416,669 transactions, including 383,326 used to measure execution time and 35,333 USDC buys under $500 used to compare execution outcomes. Alon also said Pump.fun charges a 0.45% platform fee, while Callout rewards distribute at least $300,000 per day and about $20 million over the past two months.

Comparison with Relay
Alon said that under Relay, about one out of every nine cross-chain buy transactions resulted in an error. A typical transaction took close to four seconds, and about 10% of trades took more than seven seconds.
He also said the social trading app FOMO is still using Relay.
Test window and sample size
The results came from randomized testing conducted between Sept. 28 and Oct. 7 across Robinhood, BSC, Base, Arc and Ink, and did not include Ethereum.
A total of 416,669 transaction results were recorded. Of those, 383,326 were used to measure transaction speed, while 35,333 USDC buy orders below $500 were used to compare execution performance.
Fees and incentive program
Alon said the Pump.fun app charges a 0.45% platform fee. He added that Callout rewards distribute at least $300,000 per day and totaled about $20 million over the past two months.
During a limited-time referral rewards campaign, referrers can receive all platform fees generated by referred users. The platform said it will not retain platform fee revenue during that period.
