This is the last part of the tutorial on how to build an Ether wallet smart contract. You will learn: how to do an ether transfer in Solidity the different unit of Ether (wei, gwei...)

In the previous episode we started an Ether wallet smart contract, and we can now send Ether to another address. However, everybody can call the send() function and steal all the Ether! Not great... In this video you will learn how to implement access control with the revert() built-in Solidity…

In this video, we will start to code a wallet for Ether, using a Solidity smart contract. You will learn how to send money to another address with the transfer() method of an address variable. with the transfer() method of an address variable.
