)

DomainTypes represent specific forks for specific chains, messages are signed with the domain type making 2 messages from different domains incompatible Historical Note: The fork version values for JatoTestnet and JatoV2Testnet are both set to 0x1 due to an error when these networks were initially introduced. This inconsistency does not align with the sequential versioning observed in other network and fork definitions. It's retained to maintain historical accuracy and to avoid any unforeseen issues that might arise from changing these established values. Future references and modifications should acknowledge this historical inconsistency.
