Optimism Playbook: Execution Guide with Fees & Endpoints

Preparation

• Regional endpoints with low variance.
• Gas/fee awareness; set per‑trade caps.

Execution steps

1. Simulate, validate assumptions.
2. Canary attempts with private delivery.
3. Monitor inclusion percent and adjust.

Fee management

Optimism fees include L1 data costs. Track realized gas per filled bundle, not just estimates from the mempool. During high activity (bridges, airdrops) add 20% buffer to maxFeePerGas and tighten slippage so you do not chase bad fills. Let FRB’s refund guard halt routes if spend/inclusion ratios drift beyond your thresholds.

Endpoint hygiene

• Benchmark two WSS providers per region.
• Log p50/p95 latency and error codes inside Ops Pulse.
• Rotate automatically when variance or throttling spikes.

Reporting

Share a one-page summary with your team after each rollout:

• Which endpoints performed best.
• Inclusion vs refund stats.
• Recommended parameter tweaks.

Link to /optimism-mev and /hub/execution so new operators can dive deeper.

Timeline example

Share this with stakeholders so expectations stay aligned.

Ops checklist before each session

• Confirm latest release hash and refund policy version.
• Snapshot endpoint latency and compare to baseline.
• Verify session budget plus guardrails still match treasury limits.
• Review pending support/compliance tickets before sending live capital.

FAQ

How long should simulation last?
At least 24 hours covering multiple volatility regimes.

What bundle size is safe for canaries?
~10% of your intended production size, adjusted after two clean sessions.

Do I need public fallbacks?
Yes, but cap them tightly and log every attempt for the compliance team.

What if inclusion drops midweek?
Pause, rotate endpoints, review refunds, and resume only after documenting root cause plus approval.
