Etherscan is a blockchain explorer for the Ethereum network. It solely serves as a source of blockchain data and a repository for smart contract data. You can search through transactions, blocks, wallet addresses, smart contracts, and other on-chain information on the website. It is one of the most well-known and cost-free Ethereum blockchain viewers. You can better understand how you interact with the blockchain, other wallets, and DApps by using Etherscan. All interactions on Ethereum are public. This information can also assist in keeping you secure and identifying questionable and shady activity.

A wallet address, transaction ID (TXID), contract address, or other identifier can be pasted into the search area to utilise Etherscan. Depending on what you're looking at, you'll see different information, but for the most part, you'll see connected transactions, addresses, timestamps, and quantities. Also, you can use Etherscan to directly communicate with smart contracts to conduct transactions, check gas fees, and look for airdrops.

It’s a great lense to look at the blockchain through. You can trace a transaction back to the wallet that made the purchase, for example. You can look at an Ethereum token’s smart contract and see its entire history of transactions, from the exact second it went live to the last interaction it’s had presently. Other blockchains have similar sites, such as BSCscan and Solscan, that allow you the same abilities.
