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

Shank uses Rust macros (`#[derive(ShankInstruction, ShankAccount)]`) to generate full Anchor-compatible IDLs without adopting Anchor's execution framework.

How to study this topic

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