ZeroDay Dev vs Lattice

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.

The laptop is where you grind a full problem. The phone is where you learn which tool the brief is asking for. Lattice names the core sections of data structures and algorithms and quizzes you on them. A break is recognize, diagnose, reconstruct. Smell names the tool from an unlabeled brief. By the time you sit down to a problem set, you already have the map. Progress stays on the phone. A break Recognize. Name the pattern from a tight prompt and a strip of code. Diagnose. Find the stall: bound, structure, or walk. Reconstruct. Put the move back in order from tokens or blanks. Smell A separate gym. Name the tool from a brief with the label stripped. On the phone The pack ships in the app. Scores and review live on the device. You do not need an account. Offline. A spare minute is enough. Made by Embedded Nature.
