Ethereum has revolutionized the world of blockchain with its smart contract capabilities and decentralized applications. But how do you see what's actually happening on the Ethereum network? Enter Etherscan — the go-to tool for exploring every transaction, wallet, and smart contract on the Ethereum blockchain. Whether you're a crypto beginner or an experienced trader, understanding how to use Etherscan is essential for transparency, security, and insight into your digital assets.
This guide will walk you through everything you need to know about Etherscan — from basic functionality to advanced on-chain analysis — all while keeping your experience smooth, secure, and informative.
What is Etherscan?
Etherscan is a blockchain explorer specifically designed for the Ethereum network. Think of it as a search engine for Ethereum: just like Google lets you find web pages, Etherscan allows you to look up wallets, transactions, smart contracts, and NFTs on the Ethereum blockchain.
All data on Etherscan is public and immutable, meaning once a transaction is recorded, it can't be altered or deleted. This transparency ensures trust and accountability across the decentralized ecosystem.
With Etherscan, you can answer critical questions such as:
- Was my ETH transfer confirmed?
- How much did I pay in gas fees?
- Which wallets have I interacted with?
- Where did my tokens go after a DeFi swap?
- What dApps (decentralized applications) has my wallet used?
👉 Discover real-time blockchain insights with powerful tools that simplify crypto tracking.
How Does Etherscan Work?
Etherscan functions by connecting directly to Ethereum nodes — computers that maintain and validate the blockchain. It continuously pulls data from these nodes and organizes it into a user-friendly interface.
Key services provided by Etherscan include:
- Live blockchain data retrieval: View transactions as they happen.
- Historical transaction records: Access every Ethereum transaction ever made.
- Searchable interface: Look up addresses, hashes, blocks, and contracts instantly.
Because Ethereum is open-source and decentralized, anyone can view this data — no login required. Etherscan simply makes it easier to interpret.
How to Use Etherscan: Step-by-Step Guide
🔍 Look Up a Wallet Address
Want to check someone’s Ethereum balance or transaction history? Here’s how:
- Enter the wallet address in the search bar on etherscan.io.
- Press Enter — you’ll be taken to the wallet’s overview page.
View key details:
- Current ETH balance
- Total number of transactions
- Token holdings (ERC-20, ERC-721 NFTs)
- Scroll down to see the full transaction history, including dates, amounts, and interacting addresses.
You can also explore tabs like:
- Tokens: See all tokens held in the wallet.
- NFTs: View NFT collections and individual items.
- Analytics: Track portfolio value over time.
- Multichain Portfolio: Monitor assets across 25+ blockchains.
⛽ Check Current Gas Fees
Gas fees are crucial when sending transactions. Too low, and your transaction may get stuck; too high, and you overpay.
To optimize:
- On the homepage, find the Gas Tracker widget.
- Click on it to access the Gas Tracker page.
Review suggested gas prices for:
- Low priority: Cheaper but slower confirmation.
- Average: Balanced speed and cost.
- High priority: Fastest processing (ideal during network congestion).
This helps you time your transactions wisely and save money.
🔗 Search a Transaction Hash (TxHash)
Every Ethereum transaction has a unique identifier called a transaction hash (or TxHash). To track any transaction:
- Copy the TxHash from your wallet or exchange.
- Paste it into Etherscan’s search bar.
Press Enter — you’ll see:
- Sender and recipient addresses
- ETH/token amount transferred
- Gas used and fee paid
- Confirmation status (Success/Pending/Fail)
This is especially useful when troubleshooting failed or delayed transactions.
📄 Explore Smart Contracts
Smart contracts power DeFi platforms, NFT mints, and token launches. With Etherscan:
- Paste the contract address into the search bar.
Navigate to the Contract tab to:
- Read verified source code (if available)
- See internal transactions
- Interact with functions (advanced users only)
Developers often verify their contracts on Etherscan so users can audit them for safety.
Understanding Common Etherscan Terms
Navigating Etherscan becomes easier once you understand key terminology:
| Term | Meaning |

👉 Stay ahead with live blockchain analytics that empower smarter crypto decisions.
Can You See NFTs on Etherscan?
Yes! Etherscan supports NFT tracking. If a wallet holds ERC-721 or ERC-1155 tokens:
- Go to the wallet’s page on Etherscan
- Click the NFTs tab
- View thumbnails, collection names, token IDs, and transaction history
Each NFT entry includes:
- Date of acquisition
- Transaction hash
- Amount of ETH paid (if applicable)
- Link to view full transaction details
This transparency helps verify ownership and provenance — critical for collectors and traders.
Does Etherscan Support Other Blockchains?
Etherscan was built exclusively for Ethereum. However, its parent company has launched similar explorers for other networks:
- BscScan – Binance Smart Chain
- Polygonscan – Polygon Network
- SnowTrace – Avalanche
- Arbiscan – Arbitrum
For non-Ethereum blockchains like Bitcoin or Solana, you’ll need dedicated explorers such as Blockchain.com or SolScan.
Can You Make Money Using Etherscan?
While Etherscan itself doesn’t generate income, it’s a powerful tool for on-chain analysis, which many investors use to inform trading strategies.
Key metrics to monitor:
📊 Transaction Volume
High or rising transaction volume often signals increased network activity — potentially bullish for ETH price.
🏦 Exchange Inflows/Outflows
Large withdrawals from exchanges suggest long-term holding ("hodling"), while large inflows may signal upcoming sell-offs.
👥 Active Addresses
An increasing number of daily active wallets indicates growing adoption and ecosystem health.
🐋 Whale Watch
Tracking large "whale" wallets can reveal major movements. For example:
- A whale moving 10,000 ETH to an exchange might precede a market dump.
- A whale accumulating ETH could signal confidence in future price growth.
By analyzing these patterns, traders gain an edge in predicting market trends — all using free data from Etherscan.
