Smart Contract Auditing Advanced

Advanced Smart Contract Auditing is the specialized practice of identifying security vulnerabilities, gas inefficiencies, and economic attack vectors in blockchain smart contracts. It combines code review, automated analysis tools, formal verification, and economic reasoning to find bugs before they cost users or protocols millions of dollars. Modern auditing includes fuzzing (sending random inputs to find crashes), symbolic execution (exploring all execution paths), formal verification (mathematically proving correctness), and threat modeling (considering how adversaries might exploit the contract).
