fromAddress
is an internal (smart contract) address. (ex: a smart contract calling another smart contract or smart contract calling another external address).delegatecall
because although they have a "value" associated with them they do not actually transfer that value (see Appendix H of the Ethereum Yellow Paper if you're curious). We also do not include miner rewards as an internal transfer.event
