Smart Contract QA & Testing Hub
Your central hub for everything related to blockchain QA, including test coverage, CEI testing, flaky tests, mainnet/testnet mismatches, audit support, incident analysis, and how QA engineers grow into blockchain security roles.
This hub organizes the most important AOB threads that help testers, junior developers, and early-career auditors build a strong testing mindset that matches real-world Web3 engineering expectations.

👉 https://artofblockchain.club/discussion/when-blockchain-qa-tests-pass-locally-but-fail-on-mainnet-whats
Why might a contract work on testnet but fail on mainnet? (Quiz)
👉 https://artofblockchain.club/quiz/why-might-a-contract-work-on-testnet-but-fail-on-mainnet
These help you build stories around:
gas differences
timing issues
block conditions
inconsistent RPCs
live chain behavioural differences
These topics show up in audits, postmortems, and interviews.
5. Flaky Tests, Infra Issues & Debugging QA Failures
