PolygonScan is the premier block explorer for the Polygon network, an essential tool for anyone interacting with this high-performance blockchain. This guide provides a clear, step-by-step walkthrough for beginners, teaching you how to navigate the platform to track transactions, verify wallet balances, and explore on-chain data with confidence.
What is PolygonScan?
PolygonScan is a specialized blockchain explorer designed for the Polygon network. It serves as a public ledger and search engine, providing transparency and access to all activities occurring on the blockchain. By offering real-time data and detailed analytics, it is an indispensable resource for managing digital assets, verifying transactions, and conducting research.
Key types of data you can explore on PolygonScan include:
- Transaction History: Review complete records of past transactions, including token transfers and NFT movements.
- Gas Fee Analytics: Examine the network fees (gas) paid for each transaction.
- Block Information: Track the details of newly created blocks, including the transactions they contain.
- Smart Contract Interactions: Verify contract code and review all interactions with decentralized applications (dApps).
How to Check Transactions on PolygonScan
The process for locating transaction details is straightforward and user-friendly.
Step 1: Locate the Search Bar
On the PolygonScan homepage, you will find a prominent search bar at the top of the screen. This is your primary tool for navigating the blockchain.
Step 2: Enter a Wallet Address or Transaction Hash
To view all activity for a specific wallet, paste the public wallet address into the search bar and click the "Search" button. The results page will display two primary tabs for filtering activity:
- Transactions: This tab shows all transactions involving MATIC (Polygon's native token).
- Token Transfers (ERC-20): This tab filters for transactions involving other standard tokens, such as USDT, USDC, or WETH.
How to Read Displayed Transaction Data
Once you've pulled up a list of transactions, you will see a table with several key columns of information. Understanding these is crucial for interpreting the data:
- Txn Hash: A unique identifier for the transaction, often called a transaction hash or ID. This is its fingerprint on the blockchain.
- Age: Indicates how much time has passed since the transaction was confirmed.
- From: The wallet address that initiated the transaction (the sender).
- To: The wallet address that received the assets or interaction (the recipient). This could be another personal wallet or a smart contract address.
- Value: The amount of cryptocurrency that was transferred.
- Txn Fee: The cost in MATIC paid to the network to process the transaction, also known as the gas fee.
Viewing Detailed Transaction Information
For a comprehensive breakdown of any transaction, click on its unique Txn Hash. This will open a dedicated details page containing a wealth of information, including:
- Transaction Status: Confirmation of whether the transaction was successful or failed.
- Block Number: The specific block in which the transaction was included.
- Gas Details: A full breakdown of the gas limit, gas used by the transaction, and the gas price at the time.
- Input Data: For interactions with smart contracts, this shows the specific function that was called.

How to Check a Wallet Balance
Monitoring your or any public wallet's holdings is a fundamental use case for a block explorer.
- Enter the public wallet address into the main search bar and initiate the search.
- The overview page that loads will automatically display the total balance of MATIC in the wallet.
- To see other assets, navigate to the "Token" section. This will list all ERC-20, ERC-721 (NFT), and ERC-1155 tokens held by the address, along with their current quantities and approximate USD values.
Advanced Features of PolygonScan
Beyond basic tracking, PolygonScan offers powerful tools for advanced users:
- Verified Contracts: Developers can verify their smart contract code publicly, allowing anyone to review it for transparency and security.
- Gas Tracker: A helpful tool that estimates current gas prices on the network, helping users decide whether to transact now or wait for lower fees.
- API Access: Developers can integrate PolygonScan's data into their own applications and dashboards using its robust API.
- Beacon Chain Deposits: For users interested in staking, this section tracks deposits to the Polygon staking contract.
Frequently Asked Questions
What is the difference between a transaction hash and a wallet address?
A wallet address is a static identifier for a destination, like an account number. A transaction hash (Txn Hash) is a unique ID for a single specific transfer of funds or interaction, like a receipt number for that individual event.
Why would a transaction on PolygonScan show a status of 'Fail'?
A transaction can fail for several common reasons: the gas limit was set too low, the smart contract logic encountered an error (e.g., insufficient liquidity for a swap), or the sender didn't have enough MATIC to cover the gas fee for the complex operation.
Is it safe to share my public wallet address from PolygonScan?
Yes, it is generally safe. A public address is meant to be shared to receive funds. However, sharing it does allow anyone to see your entire transaction history and balance. For maximum privacy, many users employ separate wallets for different purposes.
Can I cancel a transaction after it's been sent?
Once a transaction is broadcast to the network, it cannot be cancelled. However, if it is still pending (unconfirmed), you may sometimes be able to speed it up or effectively replace it by sending a new transaction with the same nonce and a higher gas price.
How do I find information about a specific token on Polygon?
Use the search bar to look for the token's contract address. If you don't have it, you can often find it listed on the token's official website or on major coin data sites. The token's page on PolygonScan will show its total supply, holder count, and official links.
What does 'Internal Transactions' mean on a transaction details page?
Internal transactions refer to value transfers that occur as a direct result of a smart contract executing its code. For example, when you swap tokens on a decentralized exchange, your initial transaction triggers internal transactions that handle the transfer of the new tokens to your wallet.
