We don't see a reason to call a flash loan inside a CPI, typically you would build a tx like <flashloan start, your ixes, flashloan end>, what's the motivation to flash loan inside an instruction?

transfer hooks

[jgur-psyops]

What's the application where you need a flashloan on a transfer hook? You need to react atomically and perform a flashloan after an incoming or outgoing transfer to do some re-balancing or similar?

[staccDOTsol]

no it's just to create volume thru a roundtrip tokena -> tokenb -> tokena trade, then repay flashloan.

tldr it's a lot easier to have these execute thru a transfer hook than it is to do all the logic offchain

cuz offchain is silly

so this is an offchain example:

here's one enabled by transfer hook, with a unique and real signer pushing value around:

but the pitch is immeasurably better should we be able to flashloan with mrgnfi
