What Is Etherscan?

Etherscan is a blockchain explorer specifically built for the Ethereum network. It allows users to search, view, and verify data related to:

• Transactions

• Wallet addresses

• Smart contracts

• Tokens (ERC-20, ERC-721, etc.)

• Gas fees and network activity

Unlike a wallet or exchange, Etherscan doesn’t store your assets or require login. It simply reads and displays publicly available blockchain data in a clean, searchable format.

Key Features of Etherscan

🔍 Address & Transaction Tracking

You can input any Ethereum wallet address and instantly see balances, token holdings, and a full transaction history. This is incredibly helpful for tracking your own assets, auditing contract interactions, or following large whale movements.

📜 Smart Contract Verification

Developers and users can inspect a contract’s source code and read/write functions directly from the site. Verified contracts build trust by making the code transparent and callable from the front end.

⛽ Gas Tracker

Etherscan provides real-time gas fee estimates based on network congestion. You’ll also find analytics like average block confirmation times and historical fee data—essential for optimising transaction costs.

🧠 Token & NFT Tracking

The explorer supports token balance tracking and full visibility into ERC-20 transfers or NFT collections tied to a wallet.

📈 On-Chain Analytics

Etherscan also includes simple charts and dashboards showing ETH supply, top tokens, block times, validator performance, and more. It’s a valuable resource for both individual users and analysts.
