@zpedrongmi @_saleel That’s a super clever hack/optimisation 🙌🏼
English

@feder_eth Yes it’s amazing.
We were looking at the way @_saleel uses a sha256 “hack” to basically ignore chunks of data he doesn’t parse on an email body, to avoid constraining the whole thing

My personal highlight at ethcc:
Presentation at Monad, prepared the slides, prepared a live demo.
Find out literally 2 minutes before there’s no screen and need to freestyle it basically.
Try to crack some jokes and explain Euler while waving my hands. (Narrator: he did not do a good job at it)
Crowd looks at me like I’m retarded and I conclude my presentation.

My biggest recommendation to founders, particularly, in crypto is to read this book called Fooled by Randmoness by Nassim Nicholas Taleb.
Too many people were just lucky and they believe they have skills. The good thing is that time, in general, solves this.
I was lucky too. I know it and that's why I work a lot to get better.

@MickdeG010 @liamzebedee Wow this is powerful, people will inevitably deal info like that if this becomes usable.

@liamzebedee You know that would also include selling protocol hacks right?
Reminds me of @feder_eth’s proof of exploit concept.

euler fee flow
okay after looking at fee flow, @eulerfinance did a better job at "abstract away the selling of numerous fee tokens" problem than @uniswapfnd did.
it auctions off multiple tokens at once, while buyers can build their own basket that excludes undesirable assets.
the contract doesn't explicitly hold the assets, saving on transfer costs from the markets that generate the fees. you only pay gas for what you buy.
it also uses a dutch auction instead of a fixed lot, a mechanism that naturally adapts to a changing rate of generated fees.
the tokens continue to accumulate during the auctions, so at some point the falling auction price meets the value of the generated fees (incl. gas and swap costs).
overall it's a great design that i hope to see adopted widely.
