In Web3, code is law. Once a smart contract is deployed, bugs cannot be patched easily. A single Reentrancy flaw can drain a protocol's entire liquidity pool in seconds.
Defi protocols hold billions in TVL (Total Value Locked). Attackers scrutinize bytecode 24/7 looking for the smallest arithmetic overflow.
Security isn't just about the backend. It's about Wallets, RPC Nodes, Bridges, and the Frontend DApp interacting with the chain.
Learn to think like a auditor. We cover static analysis, fuzzing foundries, and formal verification techniques used by top firms like OpenZeppelin.
Architecture breakdown: RPCs, Wallets, IPFS, and the Ethereum Virtual Machine (EVM).
Deep dive into SWC Registry: Reentrancy, Oracle Manipulation, and Front-running.
Defense patterns: Checks-Effects-Interactions, Pausable contracts, and secure AccessControl.
