JohnnyTime
JohnnyTime is a security researcher and educator. He founded Smart Contract Hacking to make developers dangerous enough to audit real smart contracts.
He builds security training and audits protocols.
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 findings a protocol will act on.
He also founded Ginger Security, a Web3 security company focused on smart contract audits, research, and hands-on protocol security work.
He teaches the work he actually does.
The course material covers real vulnerability classes, exploit mechanics, and the audit workflow students need when they move from tutorials into contests, protocol reviews, and private audits.
His public work covers security research, YouTube exploit walkthroughs, and audits for Web3 protocols. Students learn to find the bug before attackers do.
