Smart Contract Security

Covers the essential vulnerability patterns you need to know,reentrancy, access control failures, oracle manipulation, precision loss,with before/after code examples for each. The skill walks through a systematic audit process from static analysis with Slither and Mythril to fuzz testing and invariant checks in Foundry. What's genuinely useful here is the severity classification table and the audit checklist that maps common DeFi-specific risks like flash loan attacks and sandwich prevention. You get practical tooling commands and incident response steps, not just theory. The vulnerability quick reference alone saves you from having to remember which pattern prevents which exploit when you're reviewing code at 2am before a mainnet deployment.
