 **Interoperable Address**
 : A binary payload which unambiguously identifies a _target address_ on a target chain. e.g. `0x00010000010114d8da6bf26964af9d7eed9e03e53415d37aa96045`
 
+**Chain Identifier**
+: An _Interoperable Address_ with a zero-length _Address_. It identifies a chain rather than a specific address on that chain. e.g. `0x000100022045296998a6f8e2a784db5d9f95e18fc23f70441a1039446801089879b08c7ef000` is a Chain Identifier for Solana mainnet.

 : Variable length, binary representation of the [CAIP-350] chain reference. Serialization of the _ChainReference_ within a specific namespace MUST follow the algorithm defined in the namespace's [CAIP-350] profile. Chain profiles are maintained by the Chain-Agnostic Standards Alliance (CASA).
 
 **AddressLength**
-: 1-byte integer encoding the length of Address in bytes. Note that it MAY be zero, in which case the _Interoperable Address_ MUST NOT include an address. It MUST NOT be zero if the _ChainReferenceLength_ is also zero.
