Learn to break things—before attackers do.
ZeroDay Dev teaches secure coding and blockchain security through 4,000+ hands-on challenges. Learn from 120+ real-world exploits: Beanstalk, Indexed Finance, bZx, VeilCash, Sigma.Money, Bybit, and more. Each exploit is linked to verified incident records so you learn from actual on-chain events, not hypotheticals.
Practice — Build exploit intuition without reading docs. Tap vulnerable lines, drag tokens into code, get instant feedback. Filter by domain (Exploits, Solidity, Rust, DeFi, Solana) or difficulty.
Exercises — Full code challenges with reference solutions. Deeper dives when you're ready.
Exam — Prepare for real security assessments. Timed tests across domains with performance tracking. Memory-match decks for opcodes, EIPs, and security terms.
Deep Dive Hub — Curated learning tracks for Web2, Web3, Rust, ZK Proofs, and Trading. Recommended tracks driven by your weak areas. Build your own from bookmarks or missed questions.
Streaks & XP — Stay consistent and level up. Daily streaks, badges, and progression keep you coming back.
Offline-first — Learn on the subway, no Wi‑Fi needed. All content lives on your device. No account required—start immediately.
Covers reentrancy, oracle manipulation, flash loans, proxy races, ZK trusted setup, and more. Rust, Solidity, DeFi, Solana & cybersecurity.
評価とレビュー
このアプリは、概要を表示するには評価件数やレビュー件数が不十分です。
> Breaking incidents, improved — Better live/recent incident discovery, clearer briefings, and easier rediscovery from the archive.
> Completed deep dives show as finished challenges and appear in your progress history.
> Three Home Screen widgets — Glossary, Exploits, and Checklist widgets now cover more of the app, with better layouts, rotation controls, and deep links.
> Chain Guide upgrades — Sort chains faster, scan updated details, and get clearer context around decentralization, privacy, and centralized-exchange risk.
> Build lab polish — A cleaner lesson layout gets you to the code faster while keeping the guided context close by.
> More current reference material — Refreshed glossary, reference, and exploit content make the app feel more useful as a daily study and security reference.
