Understanding everything about accounts
Ethereum accounts are made up of 20-byte addresses, and you can exchange data and values between two accounts with state transitions. In general, there are two types of account in Ethereum: EOA and contract accounts. Depending on the type of account, there are four fields associated with each account: balance, contract code, storage, and nonce.
EOAs are controlled by a private key, and contract accounts are controlled by the contract code. A normal user can create an EOA by using a wallet such as MetaMask or MyCrypto. As a developer, you need to know more about these accounts and other ways to create them. In this recipe, you will learn how to create and maintain EOAs in Ethereum.
