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.

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.

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

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.

Transfer HWR 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.
