A Polygon explorer is a free, read-only website that shows everything recorded on the Polygon blockchain. To use one, paste a transaction hash, wallet address or block number into the search bar, then read the status, amounts, addresses and fee. The three guides below cover the most common jobs step by step, and the glossary explains every term you'll meet.
We wrote these guides after years of answering the same questions from readers: “Did my USDT arrive?”, “Why does it say failed if I paid a fee?”, “How do I prove I sent the money?”. Every example was checked on live Polygon PoS data in September 2026, using PolygonScan, Blockscout and our own Polygon explorer tool side by side.
What a block explorer shows you (and what it doesn't)
Think of an explorer as a window onto a shared public ledger. Every transaction on Polygon PoS is bundled into a block roughly every two seconds, and the explorer indexes those blocks so you can search them. When you look up a hash, you see the same data every node on the network agrees on, not a copy stored by some company.
What an explorer can't show you is equally important. It doesn't know who owns an address unless someone has labelled it. It can't reverse, cancel or refund anything. And it can't see what happens inside a centralised exchange: once your USDC lands in an exchange deposit address, internal movements between customer accounts stay off-chain. If a payment reached the exchange's address on the explorer but not your account balance, the exchange's support team is the one to ask.
Explorers also differ in how much they decode. PolygonScan and Blockscout turn raw input data into readable function names and list token transfers separately. Simpler multichain explorers might only show the basics. That's why we recommend checking an important transaction on two explorers; our comparison of Polygon explorers explains where each one is strongest.
Our three step-by-step guides
Each guide focuses on one job and goes deep enough that you won't need a second tab. They're written for regular users first, with notes for developers where it matters.
How to check a Polygon transaction
Find the hash, read every field, and understand success, failed, pending and dropped statuses, internal transactions, logs and finality.
How to verify a crypto payment
What counts as real proof, how to share a receipt link, QR or PDF, what the recipient must check, and the scams that fool people.
How to track a Polygon wallet
Balances, tokens with USD values, IN and OUT history, approvals, watchlists and alerts, privacy and exporting records.
Checking a transaction
This is the most searched task by far. The Polygon transaction guide starts with where to find the 66-character hash in MetaMask, Trust Wallet or an exchange withdrawal page, then goes through the fields in the order an explorer shows them. The section on failed transactions is worth reading even if everything works: “out of gas” and “execution reverted” have very different causes, and both still cost a fee.
Verifying a payment
Freelancers, small merchants and people buying crypto from each other need a way to prove a payment happened. Screenshots are easy to fake. The payment verification guide shows how to share a link that anyone can open on a public explorer, and gives the recipient a short checklist: correct token contract, exact amount, their own address, and enough confirmations.
Tracking a wallet
Whether it's your own wallet, a company treasury or a project you follow, the wallet tracking guide explains how to read balances and history, which tools send alerts, how to revoke risky token approvals, and what others can learn about you from a public address.
How to use a Polygon explorer in five minutes
If you only have a few minutes, this is the routine we use ourselves. Open an explorer and look at the search bar. It accepts four kinds of input: a transaction hash (0x plus 64 characters), an address (0x plus 40 characters), a block number, or a token name. Paste one and press enter.
For a transaction, look at the status first, then the “From” and “To” lines, then the token transfers section. The top-level “Value” field only shows POL; a USDT payment usually shows zero there because the real amount moves inside the token contract. That single detail causes more confusion than anything else on Polygon explorers.
For an address, check the POL balance, then the token holdings tab. Treat unknown tokens with caution; scammers airdrop worthless tokens with names like official stablecoins to lure people to phishing sites. Our USDT and USDC explorer page lists the real contract addresses.
If a transaction seems stuck, the Polygon mempool explorer shows whether it is waiting in the queue, and the gas tracker tells you whether your gas price was too low. Wallet setup questions, such as which chain ID or RPC to use, are answered on the network settings page.
Glossary of Polygon explorer terms
Here are the words you'll see on every explorer page, explained without jargon.
| Term | What it means |
|---|---|
| Transaction hash | Unique 66-character ID of a transaction, starts with 0x |
| Address | 42-character account ID, for a wallet or contract |
| Block | Batch of transactions added about every 2 seconds |
| Block number | Position of a block in the chain, also called height |
| Confirmations | Number of blocks added after yours |
| Finality | Point after which a block can't be reversed |
| Status | Success, Failed or Pending result of a transaction |
| Gas | Unit of computing work a transaction consumes |
| Gas limit | Maximum gas you allowed the transaction to use |
| Gas price (gwei) | Price per unit of gas; 1 gwei = 0.000000001 POL |
| Transaction fee | Gas used × gas price, paid in POL |
| Base fee / burnt fee | Protocol fee part that gets burned |
| Nonce | Counter of transactions sent from an address |
| Input data | Encoded instructions sent to a smart contract |
| Method | Decoded function name, such as transfer or approve |
| Logs (events) | Records a contract emits, like Transfer events |
| Internal transaction | Value moved by a contract during a call |
| Token transfer | ERC-20, ERC-721 or ERC-1155 movement in a transaction |
| Token approval | Permission letting a contract spend your tokens |
| Checkpoint | Snapshot of Polygon blocks submitted to Ethereum |
A few of these deserve a sentence more. Finality changed a lot in 2025: after the Heimdall v2 upgrade in July 2025, Polygon PoS reaches deterministic finality in about five seconds, compared with a minute or more before. For most payments that means a few confirmations are already irreversible. Checkpoints are Polygon's link to Ethereum; the validator layer called Heimdall periodically commits a summary of Bor blocks to Ethereum, and you can follow them live on our Heimdall checkpoint explorer. And token approvals are the silent risk in most wallets: an old unlimited approval to a compromised contract can drain a token balance without any new signature from you.
Which explorer to use for which job
You don't need to pick one explorer forever. We use PolygonScan when we want contract verification, labels and the familiar Etherscan layout. We use Blockscout when we want open-source transparency or a free API without a key. Our own tool is for fast lookups and sharing a clean receipt with someone who has never used an explorer before. For developers, tracing tools like Tenderly or Phalcon go deeper than any classic explorer. The details and scores are in the full explorer ranking, and the official Polygon documentation lists ecosystem explorers too.
If you're also funding a wallet for the first time, you can buy POL or USDC on a regulated exchange that is licensed in several jurisdictions and supports withdrawals straight to Polygon PoS. Pick the Polygon network, not Ethereum, when you withdraw, then use the guides above to confirm it arrived.
A few safety rules before you start
Explorers are safe to browse, but the ecosystem around them attracts scammers. Bookmark the explorers you use and type the address yourself; fake PolygonScan clones appear in search ads from time to time. No explorer will ever ask you to connect a wallet just to look something up, and none needs your seed phrase. The only time you connect a wallet to PolygonScan is to revoke an approval in its token approval checker or to interact with a verified contract, and even then you should read what you are signing. For background on how gas and fees work across EVM chains, the ethereum.org gas documentation is a clear primer.
