# Overview

To launch your Hyperlane deployment into a production environment, follow these steps to set up your chain’s core deployment and configure Hyperlane Warp Route (HWR) deployments.

### 1. Core Deployment

To begin you'll need to set up and productionize the core components of your Hyperlane deployment.

  <Card title="Update Mailbox Default ISM" icon="link" href="./core-deployment/update-mailbox-default-ism">
    Update the Interchain Security Module (ISM) associated with the Mailbox
    contract. The ISM acts as a critical security layer, verifying messages
    between chains. Ensure that the default ISM settings align with your
    security requirements.
  </Card>

  <Card title="Transfer Mailbox Ownership" icon="link" href="./core-deployment/transfer-mailbox-ownership">
    Transfer ownership of the Mailbox contract to a production-ready owner
    account. This step secures the Mailbox by ensuring only trusted parties have
    control over its configuration.

### 2. HWR Deployment

<Columns cols={2}>
  <Card title="Remove Trusted Relayer" icon="link" href="./warp-route-deployment/remove-trusted-relayer">
    Remove any test or development relayers that may have been configured
    initially. In production, ensure that only trusted, secure relayers are
    used to prevent unauthorized message relaying.
  </Card>

  <Card title="Transfer HWR Ownership" icon="link" href="./warp-route-deployment/transfer-warp-route-ownership">
    Transfer ownership of the HWR to the designated production owner. This step ensures that only trusted parties have control over critical HWR settings, such as ISM configurations, Validator options, and relayer settings.
  </Card>

  <Card title="Configure Rate Limit ISM" icon="link" href="./warp-route-deployment/configure-rate-limit-ism">
    Set, update, or remove the Rate Limit ISM on your HWR. The Rate Limit ISM
    caps the daily token volume that can be delivered to your HWR on each
    destination chain, bounding the worst-case loss from a bridge compromise.
  </Card>

  <Card title="Configure Pausable ISM" icon="link" href="./warp-route-deployment/configure-pausable-ism">
    Pause and unpause your HWR in an incident. The Pausable ISM is an
    emergency stop: while paused, all inbound deliveries on that destination
    chain are rejected.
  </Card>
