Pump.fun Opens Pump Bridge; Buy Error Rate Falls 92% in Tests

Pump.fun opened Pump Bridge to all app users. Its cross-chain buy error rate fell from above 11% to below 1%.

Randomized tests ran from Sept. 28 to Oct. 7 across Robinhood, BSC, Base, Arc and Ink, excluding Ethereum, and logged 416,669 transaction results. Separate test figures included 383,326 results for timing measurements and 35,333 purchases of USD Coin (USDC) under $500 for execution comparisons.

Buys were about twice as fast on Pump Bridge as on Relay, and the same amount of funds bought more tokens on average. Pump Bridge currently adds no extra cross-chain fee.

Relay cross-chain buys typically took nearly four seconds, with about 10% lasting more than seven seconds. FOMO, a social trading app, still uses Relay. Pump.fun had previously made Pump Bridge the default route for cross-chain trades in its app.
