Pump.fun has [made Pump Bridge](https://x.com/Pumpfun/status/2112980382249267382) the default route for crosschain trades in its app, replacing Relay and [claiming](https://x.com/Pumpfun/status/2112980077881266326) 2x faster buys, far fewer errors, and better fills than the provider that rival Fomo still relies on. 

## What's the Scoop?

- **Head-to-Head:** Pump.fun states that in a randomized in-app test run Sept. 28 to Oct. 7 across Robinhood Chain, BSC, Base, Arc, and Ink, the [typical buy](https://x.com/Pumpfun/status/2112980343221301455) landed in 1.95s on Pump Bridge vs. 3.88s on Relay, and [buy errors](https://x.com/Pumpfun/status/2112980356727021814) fell from 11.2% to 0.9%. 

- **The Fine Print:** Pump.fun claims the gap between spot price and tokens received is [~17% smaller](https://x.com/Pumpfun/status/2112980370543321215) on its bridge, but its own footnote shows the median buy still landed 3.0% below the app's spot price, vs. 3.6% on Relay. It also says Pump Bridge [doesn't currently charge](https://x.com/Pumpfun/status/2112980329908609273) additional bridging fees. 

- **Where the Trades Are:** Pump.fun's self-published [speed data](https://media.pump.fun/docs/speed_tap_to_toast.csv) shows Robinhood Chain made up ~53% of the 383,326 timed trades and BSC ~39%, a reminder that the [Robinhood Chain memecoin meta](https://www.bankless.com/read/robinhood-chains-unexpected-meme-meta) drives much of the app's crosschain flow. 

- **Shots at Fomo:** Cofounder alon framed the launch in an X Article titled "[How your social trading app has been robbing you.](https://x.com/a1lon9/status/2112980257611321604)", pitching Pump.fun's 0.45% platform fee as the lowest of any social trading app. It's the latest volley in the [Pump vs. Fomo rivalry](https://www.bankless.com/read/the-pump-vs-fomo-rivalry), coming days after Pump.fun [added Hyperliquid perps](https://www.bankless.com/read/news/pump-fun-adds-leveraged-perps-via-hyperliquid). Relay and Fomo hadn't publicly responded as of Wednesday evening.
