Pump.fun has replaced Relay with its own Pump Bridge as the default route for cross-chain trades, moving the Solana-based memecoin launchpad's bridging infrastructure in-house.
The switch took effect on October 21, 2026, according to research findings. Pump Bridge is now the standard path for anyone trading across chains within the Pump.fun app.
What Pump Bridge changes
The performance figures come from Pump.fun's internal tests. Buys through Pump Bridge reportedly execute about twice as fast as they did on Relay and produce 92% fewer errors.
According to the platform, Relay's error rate was above 10%, while Pump Bridge has reportedly brought it below 1%.
Latency was the other weak point. Under Relay, a typical cross-chain trade took around 4 seconds, and more than 10% of trades took longer than 7 seconds.
Pump.fun says it is optimizing toward what it describes as the fastest theoretical cross-chain buy time, approximately 1.1 seconds. That is a target rather than a current result.
On cost, Pump Bridge currently charges no extra bridging fees on trades.
Why Pump.fun built its own bridge
Pump.fun has been live on Solana since January 2024, focused on its launchpad for creating and trading memecoins. In May 2026, the platform added cross-chain swap support, opening trading across several ecosystems including Ethereum, Base, and BNB Chain.
At launch, those cross-chain trades ran through Relay. User complaints about latency and execution quality under that setup pushed Pump.fun toward building its own infrastructure, per the research findings.
Relay is not leaving the memecoin scene. Rival trading platform FOMO still uses Relay for its cross-chain routing.
What this means for traders and rivals
For traders, the practical pitch is fewer failed trades and quicker fills, with no added bridging fee at present. Moving from an error rate above 10% to below 1% means far fewer moments of clicking buy and watching nothing happen.
The caveat is that every performance figure here comes from Pump.fun itself. The 2x speed improvement and the 92% error reduction are based on the company's internal testing.
Pump.fun is now directly benchmarking its in-house product against the provider a rival still depends on. Owning the bridge gives Pump.fun more control over the user experience, the pace of upgrades, and potentially its own economics down the line.
