Etherscan is a blockchain explorer that allows you to view addresses, activities, and blocks of the Ethereum network. Block explorers are crucial tools for people who want to follow transactions and what is going on in the world.
There are also explorer options available for testnets.
When using Remix and other tools for deployment, you will be provided a link to Etherscan that is to the address of your smart contract. It is good to get comfortable using Etherscan as a developer as it can give you some important information and insights about the Ethereum blockchain.
