Ethereum Blockchain

What is Etherscan?

Etherscan is a leading block explorer and analytics platform built specifically for the Ethereum blockchain. It functions as a “public search engine” for Ethereum—providing transparent access to real-time data on transactions, blocks, addresses, smart contracts, tokens (ERC-20, ERC-721, ERC-1155), NFTs, gas fees, and more. It’s important to note that Etherscan is not a wallet—it doesn’t store funds but rather helps users explore the Ethereum ledger in a clear and intuitive way .

How Does Etherscan Work?

1. Data Retrieval & Processing
   It fetches transaction and blockchain information from Ethereum nodes using JSON-RPC, indexes it into an organized database, and makes it available for easy use via its web interface .

2. Exploring with the Search Bar
   Users enter transaction hashes, wallet addresses, contract addresses, block numbers, or token identifiers to instantly retrieve details like balances, metadata, and activity logs .

3. Smart Contract Interaction
   The Read Contract tab allows you to query contract functions like name(), totalSupply(), or balanceOf() without gas costs. The Write Contract tab lets connected users (via Web3 wallets) interact directly with contracts—such as approving token spending .

4. Gas Price Monitoring
   Etherscan’s Gas Tracker provides current and historical gas fee data, including decimal precision for accuracy—and offers recommended prices based on network conditions.

5. Utility Tools & Settings
   The platform includes converters (Base64, block/date, UTF-8, Method ID), private tagging, “advanced mode,” ignoring suspicious tokens, and more to tailor user experience .
