Inner Chain Transaction
Inner chain transaction means that both sender and receiver addresses belong to the same subchain.
For example, if sender’s address is 0000344d315050CA9B0938B6511EC342705a1f9c and the receiver’s address is 000050f134b8B0Db3D9Cc3F6cB262D4d4445Ee28 then the transaction is inner chain transaction as both address belong to the sub chain with Id 0000.
For inner chain transaction, the transaction fee will be significantly less than the inter chain transaction.
