there is a way to know how much optimization runs were aplied to a contract??

applied

Should be in the hardhat/truffle config

just used remix.

Its an old contract that I want to verify now and I remember I used optimization but dont remember the number of runs.. fshit

Remix by default doesn't apply optimization, and if you just check the checkbox without changing the number of runs remix puts that at 200, if you changed that... Good luck

haha yes I modified the opt

maybe I was thinking on a script that runs optimization and try to find the matching the output

HIT OF LUCK

If you verify it, it will be shown on the block explorer

Yes...

Well done, u worked it out

Was luck... just remembered the number of optimization was 100, pure luck.

But I think if somebody has the same problem he can write an script that compile with diff optimizations and compare the output code with the one given by ethscan/bscscan
