Domain Identifiers
Core Domains
This list includes only the deployments on chains that are managed by Abacus Works (our legal entity). Anybody can deploy Hyperlane on any chain permissionlessly - we are building a registry to reflect the community's permissionless deployments.
Hyperlane uses unique IDs for each Hyperlane-supported chain. When possible Hyperlane domain IDs match EVM chain IDs, but this is not guaranteed as we support non-EVM chains as well.
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.
