AI translates the explanation and quiz text while preserving code and answer scoring.

Native programs do not have Anchor macros to automate checks. Developers must manually assert `if !payer.is_signer { return Err(ProgramError::MissingRequiredSignature); }` and `if vault.owner != program_id { return Err(ProgramError::IncorrectProgramId); }`.

How to study this topic

  1. 1. Read the explanation once end to end, skipping the code.
  2. 2. Re-read the code snippets and say out loud what each line does.
  3. 3. Answer the quiz without scrolling back — that is the real check.
  4. 4. Read every explanation, even for the answers you got right.

Scoring

  • · Up to 30 XP from quiz accuracy.
  • · +15 XP for a perfect first attempt.
  • · +5 XP while a 3-day streak is running.
  • · 75% or higher marks the topic complete.

Check your understanding

  1. 1. What happens in native Rust if a developer forgets to check account.is_signer?
