Going to give a *sneak peak* about this paper w/ @ksk and others to FC before Twitter! There's been a surge of interest in intent-based systems like @uniswapX or CoW Swap — their claim has been to help improve the acquisition of off-chain price data on-chain But do they work?

In general, there is often the advice that you get in auction mechanism design of, "it is better for revenue and/or welfare to have more bidders in an auction than to have a better reserve prices/parameters" In fact, this is the content of the Bulow-Klemperer theorem! https://www.cs.tau.ac.il/~fiat/mdsem12/amd05.pdf

But does "more solvers (bidders) = better welfare for the user" for intents? In our paper, we find that this is *paradoxically* not always true! In fact, a user using an auction like @uniswapX may actually want to *purposely limit the number of solvers* who find prices for them Does this mean intents are broken? Nah
