Pump.fun makes its own bridge the default option
Pump.fun has launched Pump Bridge, an in-house service that now serves as the default route for crosschain trades within its application. The rollout replaces Relay, the external provider previously used by the platform and also relied on by rival social trading app FOMO.
The change gives Pump.fun more direct control over how trades move between blockchain networks. The company says Pump Bridge can complete buys twice as fast, reduce transaction errors by 92% and improve the number of tokens users receive for their money. It also says the service currently carries no additional bridging fees.
The launch follows months of complaints about slow transactions, failed purchases and execution problems with Relay. Pump.fun co-founder Alon has pointed to those issues as part of the motivation for developing an alternative. The performance figures released alongside the launch, however, are based on Pump.fun's own testing and have not been independently verified.
Pump.fun reports faster trades and fewer failures
Pump.fun compared Pump Bridge with Relay in a randomized test conducted through its app from September 28 to October 7, 2026. The test covered crosschain trades involving Robinhood, BNB Chain, Base, Arc and Ink, with users assigned to different providers several times.
The company reported that the fastest 10% of Pump Bridge purchases completed in 1.23 seconds, compared with 2.75 seconds for Relay. A typical Pump Bridge buy took 1.95 seconds, while a typical Relay transaction took almost four seconds. Pump.fun also said 90% of its trades completed before a typical Relay trade.
Reliability was another area where the company reported a difference. Relay recorded an 11.2% error rate, compared with 0.9% for Pump Bridge. Pump.fun described this as an approximately 92% reduction in errors, or roughly 12 times fewer errors. It also reported that the gap between the spot price and the value of tokens actually received was about 17% smaller with its new bridge.
What the test measured
Pump.fun said its comparison covered 383,326 timed trades for speed, 416,669 trade outcomes for errors and 35,333 completed USDC purchases under $500 for execution quality. These separate sample sizes relate to different parts of the evaluation and should not be treated as a single group of identical transactions.
The company also estimated the potential financial effect of the execution difference. Based on its observed results, a trader purchasing $500 worth of tokens 10 times a day could lose approximately $11,000 more over a year when using Relay instead of Pump Bridge.
That estimate is Pump.fun's calculation, not a guaranteed saving for individual traders. Actual outcomes can vary with network conditions, liquidity, token prices, slippage and transaction size. Independent testing across a broader range of trading conditions would help determine how consistently the reported advantages hold up.
Pump Bridge expands Pump.fun’s move toward in-house trading
Pump.fun began as a Solana-based memecoin launchpad in January 2024. It expanded into crosschain swaps in May 2026, enabling users to trade assets across supported blockchain ecosystems without manually moving funds between networks.
The new bridge follows an earlier move to bring more trading infrastructure under the company’s control. In March 2025, Pump.fun launched PumpSwap, its own automated market maker (AMM). The platform used the exchange to handle token migrations and liquidity deployment within its ecosystem, reducing its reliance on Raydium for that process.
Pump.fun has also introduced EVM limit orders, according to the supplied announcement. These orders allow traders to specify a price at which they want to buy or sell an asset on supported Ethereum Virtual Machine networks. Together, these developments show the platform’s broader effort to build a more integrated trading experience across chains and products.
What the switch means for traders and competitors
For traders, a faster and more reliable crosschain route could make it easier to buy assets on different networks. Pump Bridge’s current lack of additional bridging fees may also appeal to users, although this does not mean that trading is cost-free. Platform fees, network charges, liquidity conditions and price slippage may still affect the final amount received.
The change also has competitive implications. Pump.fun now controls a core part of its crosschain trading process, while FOMO was identified in the supplied material as a platform that continued to use Relay. Owning the infrastructure gives Pump.fun more flexibility to adjust routing and develop new features, but the test results do not establish how competing platforms will perform under identical conditions.
Pump.fun says it intends to continue reducing transaction times toward a theoretical minimum of approximately 1.1 seconds. Reaching that target will depend on factors including network confirmation times and the technical limits of crosschain transactions. For now, the central question is whether the reported improvements persist as more users trade through Pump Bridge.
The launch marks another step in Pump.fun’s effort to control more of its trading stack. Its claims of faster execution and fewer errors are notable, but sustained performance, transparent measurement and the experience of users under varied market conditions will be important in assessing the bridge over time.
