Ethereum/EVM Smart Contract Reverse Engineering & Disassembly - Blockchain Security #3

Today I'm showing how EVM disassembly works and how to reconstruct the control flow graph (CFG) of an Ethereum smart contract when you only have access to the bytecode (closed-source). It's really useful when you're looking to analyze in-depth a contract at the EVM assembly level.
