  • L_node_update
  • L_cluster_node_update
  • L_token_price_changed
  • L_blockchain_rid_topic
  • L_subnode_image_update
  • L_cluster_subnode_image_update

From the EVM transaction submitter chain:

  • G_evm_transaction_submitter_cost_topic

EIF configuration​

The Economy Chain configuration also includes the configuration for EIF.
