Practical smart contract security, not theater.

JohnnyTime created Smart Contract Hacking to teach the part of security that only clicks when you actually exploit vulnerable contracts: reading code adversarially, building proof-of-concepts, understanding DeFi mechanics, and writing audit findings that matter.

He also founded Ginger Security, a Web3 security company focused on smart contract audits, research, and hands-on protocol security work.

He teaches from the work, not around it.

The course material is built around real vulnerability classes, exploit mechanics, and the audit workflow students need when they move from tutorials into contests, protocol reviews, and private audits.

JohnnyTime's public work spans smart contract hacking education, security research, YouTube walkthroughs, and protocol-facing security services. The goal is simple: make students better at finding the bug before attackers do.
