On-chain code doesn’t forgive messy control flow. https://academy.extropy.io/pages/courses/rust-fundamentals-landing.html Mutable loops and ignored errors don’t just slow you down, they make state harder to reason about. This session focuses on Rust’s data-flow model: iterators, closures, collections, and explicit error handling.

2026 started with exploits already stacking up. Don’t let vague architecture or weak access control be your downfall. We just dropped our Web3 Dev General Security Checklist: defensive invariants, circuit breakers, granular roles, replay protection + more. Derived from real 2025 findings. 👇 https://hackmd.io/@Extropy/2026Sec1

Most bugs aren’t logic errors. They’re missing types. If your data model is vague, your code will lie at runtime. Structs. Enums. Traits. Compile-time truth, not runtime hope. Module 3 of our free Rust course 🦀Types & Traits, is live: https://academy.extropy.io/pages/courses/rust-fundamentals-landing.html
