Internal Transactions

Internal Transactions represent all transactions that have occurred in a smart contract call. Some important information included in the transaction are sender/receiver address in a token/trx transfer transaction, trx/token amount, and transfer status. Users can check all information about Internal Transactions in an internalTransaction list, which contains all transactions in a single triggerSmartContract or createSmartContract call.
