A blockchain explorer is an essential tool for anyone navigating the world of cryptocurrency. It allows you to inspect wallet addresses, track transactions, and analyze digital assets with transparency. Mastering its use can help you verify holdings, understand project risks, and make more informed decisions in the decentralized space.
In this guide, we’ll walk through the core features of a typical blockchain explorer, using Etherscan—the leading explorer for the Ethereum network—as our primary example. The principles covered apply to most major blockchain explorers.
What Is a Blockchain Explorer?
A blockchain explorer is a search engine for blockchain networks. It provides a window into public ledger data, allowing users to:
- View wallet balances and transaction histories
- Track token movements and smart contract interactions
- Monitor network activity, gas fees, and block confirmations
- Investigate project tokenomics and ownership distribution
Whether you're a trader, developer, or casual user, knowing how to use a blockchain explorer is a foundational skill.
Setting Up the Interface in Your Language
Many explorers support multiple languages. Here’s how to switch Etherscan to Chinese or other languages:
- Navigate to the Etherscan website.
- Scroll to the bottom of the page and select “Preferences” or “Settings.”
- Choose your preferred language (e.g., 中文 – Chinese).
- Save your settings and refresh the page.
You’re now ready to use the explorer in your chosen language.
How to Check Wallet Holdings
To view the holdings of any Ethereum wallet:
- On the Etherscan homepage, paste the wallet address into the search bar.
- The results will show the ETH balance and its current USD value.
- Below, you’ll see a list of ERC-20 tokens held in the wallet.
For more detailed information:
- Click “View Expanded” to see token values in both USD and ETH.
- Analyze percentage changes over 24 hours.
- Review individual tokens, their contract addresses, quantities, and prices.
This helps you understand not just what assets an address holds, but their performance over time.
Analyzing Transaction Details
Every on-chain action leaves a trace. To inspect transactions:
- Enter the wallet address again in the search bar.
- Scroll to the “Transactions” section to see recent activity.
- Each entry includes a transaction hash, block number, timestamp, gas fee, and involved addresses.
You can also filter by transaction type. For example, under “ERC-20 Token Transactions,” you can see token swaps, transfers, or smart contract interactions—essential for tracking DeFi activity or investment moves.
Researching Token and Project Information
Blockchain explorers are invaluable for due diligence on crypto projects. By examining a token’s contract address, you can uncover:
- Market cap, circulating supply, and max supply
- Number of holders and transfer count
- Official links: website, social media, whitepaper
One of the most powerful tabs is “Holders.” It shows:
- The distribution of tokens among addresses
- Percentage held by top wallets
- Insights into exchange holdings, team allocations, or whale activity
Watching these metrics can reveal concentration risks, potential sell-offs, or growing adoption.
Frequently Asked Questions
What is a transaction hash?
A transaction hash (or TXID) is a unique identifier for a transaction on the blockchain. It allows you to trace and verify every transfer or contract interaction.
Can I use blockchain explorers for networks other than Ethereum?
Yes. Most major blockchains have their own explorers, such as BscScan for Binance Smart Chain or Tronscan for TRON. The functionality is often similar to Etherscan.
Is it possible to track smart contracts with a blockchain explorer?
Absolutely. You can review contract code, published transactions, and internal calls. This is useful for verifying the behavior of DeFi protocols or NFT projects.
How do I know if a token is legitimate?
Check verified contract addresses, holder distribution, and transaction history. Be cautious of tokens with anonymous teams, uneven distribution, or no audit history.
Can I see pending transactions?
Some explorers show mempool transactions—pending but not yet confirmed. This helps estimate network congestion and gas fees.
Are blockchain explorers completely free?
Yes, they provide read-only access to public blockchain data. There are no fees for searching addresses or transactions.
Exploring Other Blockchains
While this guide used Etherscan, other networks have their own explorers. Here are a few commonly used ones:
- Bitcoin: BTC.com
- Ethereum: Etherscan.io
- BNB Smart Chain: BscScan.com
- Polygon: Polygonscan.com
- TRON: Tronscan.org

Conclusion
Blockchain explorers turn the invisible details of cryptocurrency into actionable insights. Whether you're due diligencing a new token, tracking influential wallets, or simply verifying a transaction, these tools bring transparency to your crypto experience.
With practice, you can identify trends, avoid scams, and gain an edge in fast-moving markets. So dive in, start exploring, and turn data into wisdom.
