To track a Polygon wallet, paste its public address into a Polygon explorer. You'll instantly see the POL balance, every token it holds with USD values, and the full transaction history marked IN or OUT. No login and no wallet connection are needed. For ongoing tracking, add the address to a watchlist on PolygonScan or Blockscout and export the history regularly.
Quick answer
Paste the 0x address into our Polygon wallet explorer for the balance, tokens and recent IN/OUT activity. Use PolygonScan for alerts, the token approval checker and CSV exports. Ignore tokens you never bought; they're almost always scam airdrops.
We track a handful of wallets every day as part of testing explorers: our own test wallets, a few public project treasuries and some well-known exchange hot wallets. What follows is the routine we've settled on, with the pitfalls we see readers fall into most often.
Step by step: how to track a Polygon wallet
- Copy the address. In MetaMask it's under the account name; in Trust Wallet tap “Receive” and choose Polygon. It's 42 characters, starting with 0x.
- Look it up. Paste it into the search bar of our live explorer, PolygonScan or Blockscout, with Polygon PoS selected.
- Read the balance and tokens. Check POL first, then the token list and total USD value.
- Read the history. Scan the recent activity with IN and OUT labels, then look at token transfers and internal transactions.
- Review approvals. Check which contracts can spend your tokens and revoke old ones.
- Set up alerts. Add the address to a watchlist for notifications.
- Export for records. Download a CSV of transactions a few times a year.
How to check a Polygon wallet balance
The first thing an explorer shows for an address is its native balance. On Polygon PoS that's POL, the gas and staking token that replaced MATIC in September 2024. Older wallets and some articles still say MATIC; it's the same balance under a new name. Our explorer shows the POL balance next to its current USD value, which is fetched from a public price feed when you load the page.
Below the POL balance you'll see the transaction count and, for smart contracts, contract details. If the address is a contract rather than a personal wallet, explorers mark it. That's worth knowing when you're checking a “wallet” someone gave you for a payment: sending tokens to a contract that isn't designed to receive them can make them unrecoverable.
If your wallet app shows a different number from the explorer, trust the explorer. Wallets cache data, use their own price sources and sometimes read from an RPC endpoint that's out of sync. The chain is the ground truth. If the explorer shows zero and you expected funds, you may be looking at the wrong network. The same 0x address exists on Ethereum, Base and every other EVM chain, and funds on one don't appear on another. Our network settings page shows how to confirm you're on chain 137.
Polygon wallet tokens and USD values
The token tab is where most of the value usually sits. Explorers list every ERC-20 token the address has ever received and still holds, plus NFTs under ERC-721 and ERC-1155. Our tool shows each token balance with a USD value where a price is available, and sorts the list so the valuable ones come first.
This list will almost always include junk. Scam tokens get airdropped to active addresses in bulk, often with names that imitate stablecoins or contain a website address. Some even show inflated fake prices on less careful trackers. The rule is simple: if you didn't buy it, don't touch it. Interacting with a scam token, for example by trying to sell it on a site mentioned in its name, is how many wallets get drained.
For stablecoins, check the contract. Native USDC on Polygon PoS is 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359, bridged USDC.e is 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174, and USDT is 0xc2132D05D31c914a87C6611C10748AEb04B58e8F. Our USDT and USDC explorer guide explains why USDC and USDC.e are both legitimate but not interchangeable in every app. NFT holders will find a deeper walk-through on the Polygon NFT explorer page.
Reading wallet history: IN, OUT and everything in between
Explorer history lists are more nuanced than a bank statement. On our explorer, each entry in recent activity carries an IN or OUT label relative to the address you're viewing, plus the method, counterparty and amount. You can press “Load more” to go further back.
On PolygonScan and Blockscout the history is split across tabs, and that's where people miss things. The main Transactions tab lists only transactions the address signed or received POL in directly. Token transfers lists ERC-20 movements, which is where stablecoin payments live. Internal transactions show POL moved by contracts, such as the POL you receive after a DEX swap. A wallet that only receives USDT might look nearly empty on the main tab while its token transfers tab is full.
A few patterns are worth recognising. An OUT transaction with the method approve didn't move any tokens; it gave a contract permission to spend them. Tiny or zero-value IN transfers from an address that looks almost like one you've used are a sign of address poisoning, an attempt to get you to copy the wrong address next time. And a failed OUT transaction still costs a small POL fee. For how to read an individual entry field by field, see our transaction checking guide.
Token approvals: the risk hiding in your wallet
Every time you use a DEX, lending app or NFT marketplace, you usually sign an approval allowing that contract to spend a specific token from your wallet. Many apps ask for an unlimited amount for convenience. Those approvals stay active until you revoke them, even years after you stopped using the app. If the contract is later exploited, or you once approved a malicious one, your tokens can be moved without any new signature.
PolygonScan has a token approval checker. Enter your address to see every active approval with the token, the spender contract and the allowed amount. To revoke one, you connect your wallet and sign a small transaction that sets the allowance to zero, which costs a tiny POL fee. We review approvals every few months and after any app we used makes security news. Keep in mind that revoking only protects against future misuse; it can't reverse anything already taken.
Watchlists, alerts and portfolio trackers
Checking an address by hand works for occasional lookups. For ongoing monitoring, let a tool watch for you.
| Tool | What it's good for | Account needed |
|---|---|---|
| PolygonScan watchlist | Email alerts on IN/OUT | Free account |
| Blockscout My account | Watchlists, private tags | Free account |
| DeBank / Zerion | Portfolio and DeFi positions | Optional |
| Our live explorer | Quick lookup, shareable result | None |
PolygonScan's watchlist, run by the Etherscan team, lets you add addresses with private notes and choose notifications for incoming, outgoing or all transactions. Blockscout's “My account” offers similar watchlists and private address tags, and because Blockscout is open source you can check how it works in the Blockscout docs. Portfolio trackers like DeBank and Zerion aren't explorers; they aggregate balances across many chains and show DeFi positions, which explorers don't value well. For a full comparison of what each explorer offers, our ranking of Polygon explorers scores them side by side, and the PolygonScan review goes deeper on its account features.
Developers who need custom alerts can poll an explorer API or subscribe to new blocks via RPC. Our explorer API page shows the endpoints we use for address balances and token lists.
Privacy: what your Polygon address reveals
Every address on Polygon is public. Once someone links an address to you, perhaps because you sent them a payment or posted it on social media, they can see your balance, what you hold, who you transact with and when. Analytics platforms go further, clustering addresses and labelling exchanges, funds and known entities.
A few habits limit what others learn. Use separate addresses for different purposes: one for receiving payments, one for DeFi, one for long-term holdings. Don't publish your main address. Remember that receiving from an exchange hot wallet often reveals which exchange you use. And be careful with watch-only tracking apps that ask for your address and email together; they create exactly the link you might want to avoid.
Lookups on our explorer go straight from your browser to public data providers, and we don't store queries or keep an account for you. Third-party providers may still see your IP address, as with any website. If you're funding a fresh wallet to keep things separate, you can buy POL or USDC on a regulated exchange that holds licences in several jurisdictions and withdraw directly to the Polygon PoS network; just make sure you select Polygon, not Ethereum, as the withdrawal network.
Exporting Polygon wallet history for your records
Sooner or later you'll need your history outside an explorer: for bookkeeping, a tax return, an audit or a dispute. PolygonScan offers CSV exports on the address page, with separate files for normal transactions, internal transactions, token transfers and NFT transfers. Choose a date range, download and store the files somewhere safe. Blockscout also offers CSV downloads per address.
Export at least once a year, and more often if you're active. Explorers occasionally change formats or limits, and it's much easier to reconcile three months of activity than three years. Keep the explorer links for significant transactions alongside the CSV; a link is easier to share with an accountant than a spreadsheet row. For payments you made or received, our payment verification guide shows how to save a receipt as a PDF, and the guides hub links everything else you might need.
