Have a look through the code repo - https://github.com/project-serum/anchor/blob/3958533750c83c3e90709448c4f30ed9cce0b9b8/tests/cashiers-check/programs/cashiers-check/src/lib.rs#L99
I cloned the entire program and searched around accounts and creation in my IDE.
Sweet thanks!
Hope you're on sosol.app my dude. See you in there! :)
Thanks for posting this - has been super helpful. I'm learning Rust & Sol/anchor/serum concurrently. Quick question - why use of 'to_account_info().clone()" rather just setting to accounts? Assuming it's something with rust and ownership, which I'm still wrapping my head around.

Hey @h4rkl, where did you find this in the anchor_spl documentation to add this validation? I've been working on a contract that issues token from the mint rather than transferring from a reserve account like in your example.
