Your crosschain trades have been slow, broken and overpriced for months.
Relay, used by Fomo & Pumpfun, has led traders to worse fills, missed trades and poor experiences. We refused to let this go on.

We announced crosschain trading in May, which was far later than our competitors. In less than 6 months, we have already surpassed our competitors by a landslide and are approaching the theoretical limits of seamless crosschain bridges.
On Relay, more than 1 in 9 cross-chain pical buy takes almost 4 seconds to land. And your trades receive less tokens than they should.
On Pump Bridge, there are 92% fewer buy errors. Transactions land faster, and trades get you MORE tokens for your money.
Additionally, Pump Bridge currently does NOT charge additional bridging fees onto your trades.
The same buys, side by side (Solana included for demonstrative purposes):

Speed
Pump Bridge buys are 2x FASTER than Relay (used by FOMO):
- Our fastest 10% of buys are over 2x faster than Relay’s (1.23s vs 2.75s)
- Relay’s fastest 10% are still SLOWER than our typical buy (2.75s vs 1.95s)
- 90% of Pump Bridge trades land before a typical Relay trade buy can never be instant. The intent has to be built, the intent has to land on solana, then land on the destination chain. At its fastest, an intent can only travel as fast as the speed of light can travel through the internet's infrastructure plus destination chain confirmation time. Put simply, the fastest theoretical time a buy can physically land is ±1.1s. We are actively working to close the gap that remains.
10% of our buys land within 0.13s off that limit. Relay’s fastest 10% take 2.75s, 2.5x the limit.

Reliability
Relay buys error almost 13x MORE often than Pump Bridge.
- On Relay, you’ll see an error on more than 1 in 9 buys (11.2%)
- On Pump Bridge, you’ll see an error on fewer than 1 in 100 buys (0.9%)
If you trade 10 times a day, that's more than 1 error a day on average about once every 11 days on Pump Bridge.

We supported crosschain trading later than everyone else, and we've already shipped something magnitudes better than what they rely on. No excuses.
We're continuing to invest our talent and resources to make Pump Bridge EVEN faster. Our traders deserve the best execution possible, whatever it takes to build it.

How we measured
Every number in this thread comes from a randomized test in the Pumpfun app. From Sep 28 to Oct 7, users were randomly assigned to Relay or Pump Bridge for crosschain trades on Robinhood, BSC, Base, Arc and Ink, and re-assigned several times during the test.
- Speed: 383,326 timed trades, measured from tap to the success notification
- Errors: 416,669 trade outcomes
- Fills: 35,333 completed USDC buys under $500
We ran the test from September 28th to October 7th. Since then, Pump Bridge has been the default route for crosschain trades in the Pumpfun app.
Furthermore, we’re making our full dataset public and invite anyone to verify our results:
