Transferring Ether between Ethereum accounts is the fundamental financial transaction performed by smart contracts for you Blockchain solutions. This detailed, 13-video course continues exploring Ethereum's use of Solidity language by examining the more advanced functions included in smart contracts, specifically the payable functions which allow the contract to receive Ether. Participants explore the use of fallback functions, the simplest forms of payable functions, and then define their own payable functions. Learn what happens when a smart contract has lived out its life and it needs to be destroyed; the Ether it still holds must be handed to another account and the original contract destroyed, but how? Explore the special function called selfdestruct, which deletes the smart contract from the Ethereum network. By the end of this course, you should have acquired a productive understanding of how assignment operations work depending on whether the variables on either side have been created in storage or memory.
