Wei to ether web3

Web3.js is the most popular js library to interact with Ethereum blockchain. There are some steps you can get started with web3.js. Read your Ethereum account balance through web3.js. Make balance transactions on the Ethereum network through web3.js. Make deploying smart contract transactions on Ethereum through web3.js.

As you can see, we use a built-in Web3 function to abstract away complexity and any floating-point style issues that could arise like this: Web3.toWei(1, 'ether') Making a contract call Ether vs Wei. The Ethereum Virtual Machine does not support decimals or floats. Apparently, calculations in finance are easier in integers. Therefore, to be able to send a fraction of 1 ETH, the Ethereum foundation decided to create their own metric system where the smallest unit would be 1 Wei, and 1 Ether is 1e18 Wei. Inital balance has to be less by 2 Ether const initialBalance = await web3.eth.getBalance(accounts[0]); // amount of Ether in units of wei in an account // 3. After picking the winner, the amountd are reset await lottery.methods.pickWinner().send({from: accounts[0]}); // 4.
