Overview

On-chain code is adversarial by default: it is public, immutable once deployed, and directly custodies value, so every bug is a standing bounty for an attacker. Billions have been lost to a short, well-known list of vulnerability classes. This skill is the deep reference for finding and defending them — the mental model, the concrete patterns, the trade-offs, and the mistakes that keep recurring.
