Permissionless Domain Identifiers

Unique IDs for each Hyperlane-supported chain
Note that Hyperlane domain IDs are not guaranteed to be the same as EVM chain IDs, as Hyperlane will eventually support non-EVM chains.
Hyperlane uses proprietary domain IDs to reference each Hyperlane-supported chain.
When sending a message, users must provide the domain ID of the destination chain. When receiving a message, the recipient will be passed the domain ID of the origin chain.
This list includes only the deployments on chains that are managed by Abacus Works (our legal entity). Anybody can deploy Hyperlane on any chain using Permissionless Interoperability and thus this list may not be exhaustive.
