Etherscan is a powerful blockchain explorer that allows users to monitor the Ethereum network in real time. Whether you're tracking a recent transaction, verifying wallet balances, or preparing for tax reporting, Etherscan provides transparent access to on-chain data. Despite its utility, many beginners find the platform overwhelming due to its technical interface and lack of native Japanese or simplified language support.
This guide breaks down Etherscan’s core functionalities in clear, step-by-step detail—complete with practical examples and visual descriptions—to help new users confidently navigate Ethereum transactions, token movements, and security settings. By the end, you’ll know how to view your activity, interpret key metrics, and export data for accounting or analysis.
What You Can Do with Etherscan
Etherscan serves as a public ledger for the Ethereum blockchain, offering real-time visibility into transactions, smart contracts, token transfers, and network health. Think of it as a search engine for everything happening on Ethereum.
Key features include:
- Checking wallet balances and transaction history
- Tracking the status of pending or failed transactions
- Analyzing token supply and holder distribution
- Monitoring overall network congestion and gas fees
- Revoking unnecessary token approvals for improved security
Let’s explore these functions in depth.
How to Check Your Transaction History
The most common use of Etherscan is reviewing your wallet’s activity. To get started:
- Visit etherscan.io
- Paste your Ethereum wallet address into the search bar at the top
- Press Enter
You’ll be taken to a detailed overview page showing all on-chain activity linked to that address.
Here’s what you can see:
- ETH Balance: Current amount of Ether held
- Estimated Value (in USD): Real-time fiat equivalent
Transaction History: Full list of sends, receives, and contract interactions
- Transaction Hash (TxID)
- Block number
- Timestamp
- From/To addresses
- Amount transferred
- Gas fee paid
Each transaction can be clicked for deeper insights—such as confirmation status, nonce value, and input data. This is especially useful when troubleshooting failed transactions or verifying receipt of funds.

How to Monitor Transaction Status
When sending crypto, delays can cause anxiety. Etherscan removes the guesswork by letting you track transaction progress using the Transaction Hash (TxID).
Steps:
- Copy the TxID from your wallet or exchange
- Paste it directly into Etherscan’s search bar
- View real-time status
Status indicators are color-coded:
- ✅ Success (Green): Confirmed and completed
- ⏳ Pending (Gray): Waiting for miners to process
- ❌ Failed (Red): Execution error—funds not sent
A transaction only finalizes once it reaches “Success.” If stuck in “Pending” for over 30 minutes, consider increasing gas fees via a replacement transaction.
Understanding these states helps avoid double-spending attempts and ensures timely fund delivery—critical during high-market-volatility periods.
Monitor Ethereum Network Health
Etherscan’s homepage displays live network statistics vital for informed decision-making:
- Current ETH price and market cap
- Average gas price (Gwei)
- Total daily transactions
- Latest block height and timestamp
High gas prices often signal network congestion—common during NFT mints or major DeFi launches. By checking this data before transacting, you can time your moves to save on fees.
For example, weekends or U.S. business hours typically see higher traffic. Scheduling non-urgent transactions during off-peak times (e.g., early morning UTC) may reduce costs by up to 70%.
How to View Token Information
Beyond ETH, Etherscan lets you explore ERC-20 tokens like USDT, DAI, or UNI.
To check a token:
- Search the token symbol (e.g., "USDT") in the search bar
- Select the correct contract from results
Review details like:
- Total supply
- Number of holders
- Top wallets by balance
- Recent transfer activity
This transparency helps assess token legitimacy and popularity—essential for due diligence before investing.
For instance, if one wallet holds 80% of a new token’s supply, it could indicate centralization risk or potential manipulation.
Advanced Security: Revoke Token Approvals
One often-overlooked but critical feature is Token Approval Revocation.
When using DeFi platforms or NFT marketplaces, you grant smart contracts permission to spend specific tokens on your behalf. Leaving unused approvals active poses security risks—if a contract gets exploited, attackers could drain your funds.
Etherscan allows you to revoke these permissions:
- Connect your wallet (e.g., MetaMask) via the “Connect Wallet” button
- Go to More > Token Approvals
- Review active allowances
- Revoke access for unused or suspicious contracts
Regularly auditing approvals enhances account security—think of it as cleaning up old app permissions on your phone.
How to Export Transaction History from Etherscan
For tax reporting or financial tracking, exporting your transaction history is essential. Etherscan supports CSV exports across four categories:
1. ETH Transactions (Outgoing & Incoming)
These are standard Ether transfers between wallets.
How to export:
- Search your wallet address
- Click Transactions under "Transactions"
- Scroll down and click CSV Export
- Note: Max 5,000 entries per export; split by date if needed
2. Internal Transactions (Contract-Based Transfers)
These involve ETH movements triggered by smart contracts—common in yield farming or bridge services.
How to export:
- After searching your address
- Select Internal Transactions
- Click CSV Export at the bottom
⚠️ These won’t appear if no contract interactions occurred.

3. ERC-20 Token Transfers
Includes all stablecoins and utility tokens built on Ethereum (e.g., USDC, AAVE).
How to export:
- After searching your address
- Go to Token Transfers (ERC-20)
- Export via CSV Export
Ensure this file is included for accurate profit/loss calculations.
4. NFT Transfers (ERC-721 & ERC-1155)
Tracks NFT minting, sales, and transfers across collections.
How to export:
- After searching your address
- Navigate to NFT Transfers
- Export using CSV Export
Useful for documenting NFT portfolio changes for tax or audit purposes.
