This is the final step. With the market configured, parameters verified, and user experience tested, the changes are ready to be pushed to the live blockchain.

### The Timelock Lifecycle

Gearbox governance enforces a **24-hour Timelock** on all critical changes. This security feature provides users time to exit if they disagree with a parameter change.

Deployment consists of two distinct actions:

1. **Queue (Propose):** Submit the transaction to the Timelock contract. The 24-hour countdown begins.
2. **Execute (Apply):** After the countdown ends, submit a second transaction to apply the changes.

### Finalize the Proposal

Navigate to the GIP page in the interface.

1. **Finalize:** Click **"Finalize GIP"**. This locks the configuration and prepares the transaction data.
2. **Set Earliest Execution Date:**
   * The default timelock is 24 hours.
   * **Calculation:** `Current Time + Signing Buffer + 24 Hours`.
   * *Recommendation:* Add a buffer (e.g., 2 hours) to allow sufficient time for collecting signatures from multisig signers before the target execution time.


**Troubleshooting:** If last-minute edits are required, click **"Reopen for Changes"**. Re-finalization is required after editing.

## Queue the Transaction

The interface generates a link to the **Permissionless Safe App**.

1. Click the link to open the Safe App.
2. **Sign & Submit:** Execute the transaction in the Safe. This initiates the onchain timer.

Once the timelock expires:

1. Return to the **Permissionless Safe App**.
2. **Sign & Submit:** Execute the final transaction.

### Deployment Complete

The market is now live on the blockchain.

* **New Pools:** Lenders can deposit assets.
* **New Strategies:** Borrowers can open Credit Accounts.

**Requirement:** Ensure the frontend PRs have been merged so users can view the new market and strategies in the app.
