General question about sandwiches and curve pools. For people who are

doing a swap or LP provision transaction, why don’t they always send the transaction privately?

It looks like a service like blocknative boost is a pretty simple RPC URL replacement, for Ethereum Mainnet at least.

So why do people still make public transactions? Is it because they don’t care because sometimes sandwich attack cost can be pretty tiny sometimes relative to swapping large sums? I’m trying to get a better understanding of the risks of using pools.

I think it's mostly inexperience, and lack of awareness. Thankfully using the Curve UI, default slippages are set low by default, on both the router, and swapping directly via the pool. Of course the end user can change these values if they wish. Some aggregators have default slippage values set more leniently which can lead to losses. And for some reason, people still swap through something like metamask directly that not only takes a fee, but can have slippage values set higher (i've seen as much as 5%) I would attritbute not using protected RPC's to the same thing, just lack of general knowledge...

Exactly.. Some places have extremely not customer friendly defaults for slippages and fees. I have seen 2% easily taken away in every conversion

on soylana, phantom wallet charges 1% to swap lmao

It's crazy how high it is but I know too many people who still use it (myself included)
