Pump.fun swaps Relay for its own Pump Bridge on cross-chain trades

Pump.fun has stopped renting its cross-chain plumbing and started building its own. The Solana-based memecoin launchpad now sends cross-chain trades through Pump Bridge by default, replacing Relay, the outside provider it used before.

What Pump Bridge changes

The switch happened on October 21, 2026, according to the research findings. Pump Bridge is now the standard route for anyone trading across chains in the Pump.fun app.

The headline numbers come from Pump.fun’s internal tests. Buys through Pump Bridge reportedly execute about 2x faster than they did on Relay. They also reportedly produce 92% fewer errors.

The before-and-after picture is stark if the figures hold. Relay’s error rate was over 10%, according to the platform. Pump Bridge has reportedly brought that below 1%.

Latency was the other sore spot. Under Relay, a typical cross-chain trade took around 4 seconds. More than 10% of trades took longer than 7 seconds.

Pump.fun says it is optimizing toward the fastest theoretical cross-chain buy time, which it puts at approximately 1.1 seconds. That is a target, not a current result.

Cost matters too. 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.

That changed in May 2026, when the platform added cross-chain swap support. The upgrade opened 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 exiting the memecoin scene, though. 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 simple. Fewer failed trades and quicker fills, with no added bridging fee at the moment. 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.
