Feb 27 at 11:37 comment added Jon C Certainly! Here's the code in the syscall to perform a cross-program invocation. You'll see that it takes all the seeds from invoke_signed and creates program addresses with those, and promotes those addresses to signers in the instruction: github.com/solana-labs/solana/blob/…
Feb 27 at 7:44 comment added Maksim Tolstikov Thank you very much for your answer! Is it possible, if you know, to share the piece of Solana code where this check happens - "Only the program whose id is used to generate the PDA may "sign" for that account, so it's totally safe."?
