 This page lists the parent chains that are officially supported in Orbit, including mainnets, testnets, and options for local development. While the Orbit SDK provides functionality to enable custom parent chains, support is limited to the chains explicitly listed on this page. Developers are welcome to use the Orbit SDK to configure and deploy custom parent chains; however, such setups, including deploying the required creator and template contracts, are beyond the scope of our official support.
