6/6 — Gas Optimisation Basics — Check your understanding
Guardrail You should be able to justify every optimization with numbers and explain why it’s still safe. If you can’t, revert it.
Privacy is necessary for an open society in the electronic age.
Audit-ready You should have proofs/tests for unchecked code, and a short note on why each optimization exists. If an auditor asks, you can point to numbers.
Clarity bias If two approaches are close in gas, you default to clearer code. You can articulate why.
Key points
- Explain your data-location choices:And impact on gas.
- Describe one safe unchecked:Use and the proof/tests behind it.
- Show before/after numbers for:An optimization and why it stayed.
- Name an “optimization” you:Rejected and why (clarity/safety/cost).
