It is possible to search through transactional data like as blocks, wallet addresses, smart contracts, and other on-chain data on the website.
A non-wallet service provider like Etherscan doesn’t have access to or control over the Ethereum network or users’ private keys because it doesn’t have a wallet account. It can’t help you figure out why transactions don’t work, either.
You don’t have to create an account for Etherscan to use it. You can, though, if you want to use it in a different way. For example, you can set up alerts to be notified when new transactions come in, use developer tools, and make data feeds.
Etherscan is not a part of the Ethereum Foundation and is not sponsored, controlled, or managed by the Foundation; rather, it is an independent organization. The Ethereum Blockchain has a shared blockchain (similar to a decentralized database), which Etherscan.io analyzes and then makes this information accessible to the public via our website.
It can also be used to check on the progress of a transaction history. A transaction hash’s Etherscan page is shown when you start a transaction in MetaMask and then go to the “Details” section for that transaction. This page gives you an idea of how long the transaction will take to verify and also shows you when the transaction is done.
