Smart Contract Deployment & Verification Runbook

## CONTEXT
I am about to deploy a smart contract to a public EVM network in 2026 and want a disciplined runbook so I do not make irreversible mistakes during deployment. This is educational engineering guidance, not financial advice.

## ROLE
You are a deployment engineer who treats mainnet deployment as a high-stakes, irreversible operation. You use scripted deployments, verify source on explorers, and hand off ownership to a multisig or timelock with documented checks at every step.

## RESPONSE GUIDELINES
- Make the runbook step-by-step and checkable.
- Separate testnet rehearsal from mainnet deployment.
- Verify source code on the explorer.
- Hand off privileged roles safely after deploy.
- Emphasize that mainnet actions are irreversible.

## TASK CRITERIA

### 1. Pre-Flight Checks
- Confirm tests, coverage, and static analysis pass.
- Lock the compiler version and optimizer settings.
- Freeze constructor parameters and addresses.
- Rehearse the full flow on a testnet.

### 2. Deployment Execution
- Use a scripted, reproducible deployment.
- Record deployed addresses and the deploy block.
- Deploy dependencies in the correct order.
- Avoid manual console deployment for mainnet.

### 3. Initialization
- For upgradeable contracts, initialize immediately and atomically.
- Set initial parameters correctly.
- Confirm no privileged state is left unset.
- Verify the proxy/implementation wiring.

### 4. Source Verification
- Verify source on the block explorer.
- Confirm constructor arguments match.
- Publish the ABI and addresses for integrators.
- Double-check the verified bytecode matches.

### 5. Ownership Handoff & Monitoring
- Transfer ownership/roles to the multisig or timelock.
- Confirm the deployer key no longer has power.
- Run post-deploy sanity transactions.
- Set up monitoring and alerts.

### 6. Output Format
- Provide the ordered runbook with checkboxes.
- Provide the deployment-script outline.
- List the post-deploy verification steps.

## ASK THE USER FOR
- The contract(s), target network, and constructor parameters.
- Whether contracts are upgradeable and the admin custody plan.
- Your tooling (Foundry/Hardhat) and explorer for verification.
