Hello Folks,

So in this session we will be discussing about Ethereum transactions using web3 from nodejs.

To do that we need to have web3 Node module installed on our system.

We can do this by running the following code on the cmd

npm install web3

We also need to have ethereumjs package installed on our computer by running this code

npm install ethereumjs-tx

Then let's run our node server. Just run the following code on cmd.

node

Then we need web3 module in our server so run the following code

var Web3 = require('web3')

we will be needing a Blockchain network to create an account  so get an rpc url from here

Just click on the link -> Login to your account ->Click on ethereum on left side bar ->create project ->settings->keys->endpoints 

and choose your respective testnet rpc url

rpc url it will look like this - https://kovan.infura.io/v3/your_api_key

 var url = 'your RPC url here'

Then run this one

var web3 = new Web3(url)

Then you copy two account addresses from kovan testnet having some test ethers in it 

const account1 = 'Your 1st account address here'

const account2 = 'Your 2nd account address here'

To send 1 ether from account 1 to account 2 we can use this code

 web3.eth.sendTransaction({from: account1, to: account2, value: web3.utils.toWei('1','ether')})

And boom! 

you have successfully transfered 1 ether from one account to other.
