Hamonis

Hamonis is a Web3 learning platform that teaches blockchain development and security through hands-on exploit challenges. Rather than relying on slides or simulated exercises, it gives learners containerized environments with live RPC endpoints, real bytecode, and vulnerable smart contracts to investigate. Challenges cover DeFi security topics such as reentrancy, oracle manipulation, flash-loan attacks, and signature replay, with guided learning paths that progress from introductory flaws to advanced protocol auditing.

Learners can solve challenges, record demonstrated flaw-finding skills on their profiles, earn points and badges, climb a leaderboard, and unlock more difficult tracks. The platform also supports community contributions: users can upload challenges, review others’ work, and learn from security researchers’ write-ups. Its instant deployment is designed to let participants begin without setting up a local node or dependencies.

For organizations, Hamonis offers team training with customized learning paths, private challenges, analytics, onboarding and support, SSO, and enterprise integrations. Its services are aimed at developers, researchers, startups, universities, and Web3 teams seeking practical blockchain security training.
