Overview
- Pump.fun launched Pump Bridge and made it the default cross‑chain route in its app after a switch on Wednesday, Oct. 21, 2026.
- In an internal randomized test run from Sept. 28 to Oct. 7 covering about 400,000 trade outcomes, Pump.fun reported average buy times of 1.95 seconds on Pump Bridge versus 3.88 seconds on Relay.
- The company said Pump Bridge cut buy errors to about 0.9% from Relay’s 11.2% and narrowed execution gaps for small USDC buys, producing materially better fills in its app tests.
- Pump.fun currently charges no extra bridging fee on Pump Bridge, but the performance claims are company‑sourced and the firm says it will publish the underlying dataset for independent analysis.
- Relay remains in use by at least one rival, FOMO, and the shift highlights how owning bridge infrastructure can let platforms tune speed, reliability and economics for multi‑chain trading while broader questions about memecoin liquidity and long‑term token activity persist.
