Fair execution doesn’t remove arbitrage or price discovery.
It removes execution abuse: users being quoted one outcome and receiving a worse one because intermediaries can reorder, sandwich, or selectively fill against them.
Jito turned MEV into a marketplace to extract from the Solana userbase. Fair execution asks whether users should keep more of that value.
Read-through cache in front of Amazon S3 that cuts egress costs by 95%+
Takes only minutes to set up
A single DNS entry and your users hit hyperlocal nodes near them anywhere in the world
Faster egress, without the AWS bill
The most retarded (and false) take I see is that the public internet is slow
Anytime I see that, I automatically assume they made bad infra decisions and rely on BGP routing from 1989
Only way that reconciles
The Scam in Plain Numbers:
At quote time, PropAMMs offer prices 1.3 bps better than Pyth oracle fair value. Raydium quotes at 0.0 bps — dead fair. Jupiter sees the PropAMM quote is best and routes to it.
At execution time, the actual fill lands 10.1 bps worse than what Raydium would have given for the same hop. We've confirmed this pattern across multiple PropAMM providers.
The net extraction: they quote +1.3 bps to win the route, then execute at −10 bps. That's ~11 bps of invisible spread between what they promised and what they delivered — on the USDC→SOL leg alone.
How It Works Mechanically:
They quote a price they have no intention of honoring. As JIT liquidity providers, they don't hold inventory in the pool. When your transaction hits the chain, they provide just-in-time liquidity at a worse rate than quoted. Your slippage tolerance (3 bps in our case) gives them room to fill below the quote, and since Jupiter already committed to the route at quote time, the trade goes through regardless.
The Tell:
In the transactions we dissected, hop-level data made it clear: 11,111,990 lamports received versus 11,123,249 that Raydium would have given. That's roughly $0.001 per $1 swapped — every single time, across millions in daily volume. This isn't one bad actor; it's a pattern we've observed across several PropAMM pools on Jupiter.
Peter Thiel on the freedom of thought:
“In a democracy, what 51% of the population believes is probably better.”
“If you have 70% of the population believe something— it’s even more true.”
“But if you go from 51% to 70% to 99.99%— you’ve done from a democracy to North Korea.”
