regarding the ResupplyFi hack, preliminary investigation shows that the ResupplyPair contract uses an empty ERC4626 wrapper as the price oracle. thus the hacker used only 2 crvUSD to borrow 10M reUSD.... 0xffbbd492e0605a8bb6d490c3cd879e87ff60862b0684160d08fd5711e7a872d3

good example of how auditors and *hackers* think differently: - threat model: inputs are generated by associated ix builder, so minimal checks is needed on chain. there is not attacking surface in this senario - svm: if the unsafe code fuck up, invalid memory access only leads
Good example of how *not* to use unsafe - `from_raw_parts` instead of `.get_unchecked(data_offset..)` - does not mark his method as unsafe or explain why the assumption on the data should always hold - probably didn't even benchmark before making this change
