To start testing transactions and smart contracts, you add an account. Accounts are password-protected keys that can hold ether, secure ethereum-based tokens or coins, and control contracts. In the Ethereum Wallet, go to File, New Account, enter a password, and press Enter. Confirm your password, and press Enter. If you're new to Ethereum and haven't done any coding with smart contract languages yet, we recommend getting started with Solidity or Vyper. Only look into Yul or Yul+ once you're familiar with smart contract security best practices and the specifics of working with the EVM. Yul. Intermediate language for Ethereum.

This is a decentralized “world computer” where the computing power is provided by all those Ethereum nodes. Any nodes providing computing power are paid for that resource in Ether tokens. With smart contracts, you can perform various tasks such as decentralized voting and much more. In simple terms, a smart contract is a contract that executes, enforces, manages, and handles the payment automatically. To execute a smart contract on Ethereum, you’ll need tokens (Ether).
