Why this module exists. Smart contract and Web3 pentest is its own discipline — the rules of “immutable, public, value-at-stake” change the testing approach entirely. This module covers fundamentals for traditional web pentesters extending into the Web3 surface.
What is different about smart contracts
- Immutable once deployed: no patch cycle (mostly). Find the bug, lose the funds.
- Public source code: bytecode is on-chain; usually source code published for verification.
- Direct financial exposure: vulnerabilities translate to ETH / tokens immediately.
- Gas economy: every operation costs; some attacks exploit gas pricing.
- Composability: contract A calls contract B which calls contract C; integration risks compound.
