7/9 — Ethereum Accounts & EOAs — Good practice
ChecklistsA few habits erase most account headaches. Think checklists: fetch nonce → sign → broadcast → monitor → replace if needed. Add guardrails like “warn if pending with same nonce” and “show the gas payer clearly.”
TrainingOnboard teammates with screenshots so they understand nonces and gas before touching production keys. Codify in runbooks; don’t rely on tribal knowledge. As you scale, give different services different keys to avoid collisions, and rehearse recovery steps.
Key points
- Always model flows explicitly:As “EOA signs → contract executes → downstream calls,” with the EOA paying throughout.
- Fetch the latest nonce:From a reliable source before sending; handle “nonce too low” and “replacement” errors clearly in UIs.
- When batching, pre-compute and:Lock in nonce assignments to avoid accidental collisions.
- Explain gas payment up:Front so users know they will pay even when interacting with contracts.
- Use keeper services or:Cron jobs deliberately; treat them as EOAs that must be funded and monitored.
- In testing, avoid sharing:One dev key across many people; give each tester their own funded EOA.
- Document how to speed:Up or cancel a transaction so users and support teams can fix problems fast.
- Instrument scripts to alert:On pending transactions older than a threshold so you can replace or cancel proactively.
- Keep a small “break:Glass” wallet with spare funds to rescue stuck transactions by bumping gas or replacing them.
