Solidity Debugging & Tooling Hub
Smart contract debugging isn’t just about fixing “one bug” — it’s about understanding how state, logs, tools, testnets and mainnet all behave differently.
This hub collects all AOB discussions and quizzes related to:
Hardhat debugging
Testnet vs mainnet differences
Flaky tests and infra issues
Production incidents
Logging & monitoring
Client demo failures
Use this page as your starting point whenever you’re stuck, preparing for interviews, or trying to explain debugging stories to hiring managers.
1. Getting started With Hardhat Debugging
Debugging smart contracts is tough — how do you make it easier?
👉 https://artofblockchain.club/discussion/debugging-smart-contracts-is-tough-how-do-you-make-it-easier
Struggling with Hardhat debugging — am I missing something beyond console.log?
👉 https://artofblockchain.club/discussion/struggling-with-hardhat-debugging-am-i-missing-something-beyond-consolelog
Hardhat debugging mistakes juniors repeat (logs vs state assumptions)
👉 https://artofblockchain.club/discussion/need-help-hardhat-debugging-mistakes-juniors-repeat-logs-vs-state-assumptions
What does Hardhat mean in blockchain? (tool fundamentals)
👉 https://artofblockchain.club/discussion/can-anyone-tell-me-what-does-hardhat-mean-in-blockchain
Hardhat or Foundry first — what actually helps in your first smart contract role?
These threads are ideal if you’re stuck in day-to-day debugging and want to level up from “print logs” to real reasoning about state and tooling.
2. Testnet vs Mainnet: When Things Break Late
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
When blockchain QA tests pass locally but fail on mainnet — what’s happening?
👉 https://artofblockchain.club/discussion/when-blockchain-qa-tests-pass-locally-but-fail-on-mainnet-whats
These help you build stories around:
gas differences
fork vs live chain
environment assumptions
infra misconfigurations
Perfect for interview use-cases and postmortem thinking.
3. Flaky Tests, Infra & QA Pain Points
Flaky smart contract tests — how do blockchain QA engineers handle it?
👉 https://artofblockchain.club/discussion/flaky-smart-contract-tests-how-do-blockchain-qa-engineers-handle-it
Use this when you want to talk about:
nondeterministic behavior
async / timing issues
race conditions
CI problems in Web3 setups
4. Logging, Monitoring & On-Chain Visibility
Efficient logging & monitoring in Solidity smart contracts on EVM chains
👉 https://artofblockchain.club/discussion/how-to-implement-efficient-logging-and-monitoring-in-solidity-smart-contracts-on
This thread supports deeper topics like:
event design for debugging and analytics
log vs state-based observability
what to emit for post-incident analysis
5. Production Incidents & Client Demo Failures
Handling production incidents as a junior Solidity engineer — how do you respond?
👉 https://artofblockchain.club/discussion/handling-production-incidents-as-a-junior-solidity-engineer-how-do-you
When a smart contract demo fails mid–client call — how do you communicate?
👉 https://artofblockchain.club/discussion/when-a-smart-contract-demo-fails-mid-client-call-how-do-you-communicate
These are gold for:
incident storytelling in interviews
explaining failure handling
communicating calmly under pressure
learning how seniors expect you to behave when things break live
6. Debugging-Relevant Quizzes (Concepts That Cause Bugs)
When does a fallback function trigger? (Quiz)
👉 https://artofblockchain.club/quiz/when-does-a-fallback-trigger
What does delegatecall do? (Quiz)
👉 https://artofblockchain.club/quiz/what-does-delegatecall-do
These quizzes sharpen your understanding of:
control flow
how unexpected calls happen
where storage / context can get messed up
These are often the root cause of “weird” bugs and security issues.
7. Upgradeability & Storage Conflicts (Debugging State Layout)
Struggling to understand initializer guards & storage conflicts in upgradeable contracts
👉 https://artofblockchain.club/discussion/struggling-to-understand-initializer-guards-and-storage-conflicts-in-upgradeable-smart-contracts
Even though this looks like a “security / design” topic, most real-world upgrade bugs show up as confusing debugging sessions. This thread fits both the SC Security Hub and this SC Debugging Hub, so we cross-link it here.
