Ganache includes 10 accounts, and which each has 100 Eth in its account. These accounts can then be used to perform transactions on the blockchain. The server places itself on a certain port. In the example above, this port is TCP port 8545. This port will be used to connect from Remix to our blockchain and deploy our smart contract.

Once we deploy our contact, we can use Remix to test it. In the following we see we can test the add() method for the contact, and add 5 and 3, with a result of 8:
