The Polygon block explorer URL for mainnet is https://polygonscan.com, the chain ID is 137 (0x89), the gas token is POL, and a working public RPC URL is https://polygon-bor-rpc.publicnode.com. For the Amoy testnet use chain ID 80002, https://polygon-amoy-bor-rpc.publicnode.com and https://amoy.polygonscan.com. The cards above let you copy each value or add the network to your wallet in one click.
Quick answer
Most wallets already know Polygon, so you rarely need to type anything by hand. When you do, the chain ID is what really matters: 137 for mainnet, 80002 for Amoy. The RPC URL decides who relays your transactions, and the block explorer URL only decides which website opens when you tap “view on explorer”. Avoid polygon-rpc.com, which stopped working for public use.
We rechecked every value on this page on 25 September 2026 by querying the endpoints directly and comparing the chain ID each one returned. If something changes, the settings cards are the first thing we update.
Polygon network settings at a glance
Three Polygon networks still matter for wallet settings. Polygon PoS is the live mainnet where payments, stablecoins and most apps run. Amoy is the current PoS testnet, anchored to Ethereum Sepolia. Polygon zkEVM is in archive mode after its sequencer shut down in July 2026, so you only need it to read old records.
Here are the mainnet values in the exact order most “add network” forms ask for them:
| Field | Polygon PoS mainnet |
|---|---|
| Network name | Polygon Mainnet |
| RPC URL | https://polygon-bor-rpc.publicnode.com |
| Backup RPC | https://polygon.drpc.org |
| Chain ID | 137 (0x89) |
| Currency symbol | POL |
| Block explorer URL | https://polygonscan.com |
A third free endpoint, https://1rpc.io/matic, also answered correctly in our test. All three are keyless and open to browser requests, which is why our own live Polygon explorer falls back to them when the Blockscout API is slow. If you are building an app rather than setting up a wallet, a private endpoint with an API key is more reliable; our Polygon explorer API guide compares the options.
Amoy testnet explorer URL and RPC
Developers need Amoy for testing contracts without spending real POL. The Polygon Amoy testnet explorer URL is https://amoy.polygonscan.com, the chain ID is 80002 (hex 0x13882), and the currency symbol is POL, even though testnet POL has no value. Working public RPCs are https://polygon-amoy-bor-rpc.publicnode.com and https://polygon-amoy.drpc.org.
You can get test tokens from the official Polygon faucet, which hands out small amounts and uses anti-bot checks. If you still have Mumbai (chain ID 80001) saved in your wallet, delete it: Mumbai was deprecated in April 2024 and no longer produces blocks. Our Amoy testnet explorer guide covers faucets, testnet explorers and common deployment errors in more depth, and the Mumbai explorer page explains what happened to old testnet data.
Polygon zkEVM settings (archived network)
Polygon zkEVM used chain ID 1101 and ETH as its gas token. Polygon Labs announced in June 2025 that the Mainnet Beta would be sunset, and the sequencer stopped around the start of July 2026. That means new transactions are no longer processed in the normal way. We keep the zkEVM card in the widget so you can recognise the network in an old wallet and open historical records on https://zkevm.polygonscan.com, but treat that explorer as read-only and be aware its availability may change.
If you still hold funds there, don't try random RPC endpoints or “recovery” sites. Follow the official process on the Polygon zkEVM page and read our zkEVM explorer overview first.
How to add Polygon to MetaMask
MetaMask ships Polygon Mainnet as a built-in popular network, and its default configuration points “view on block explorer” links at PolygonScan. You have three ways to get it:
- Use the button above. On desktop, click “Add to wallet” on the Polygon Mainnet card. The page asks MetaMask to add chain 137 with our tested RPC endpoints and PolygonScan as the explorer. MetaMask shows every value before you approve, so read them.
- Pick it from the popular list. Open the network selector, choose “Add network”, and select Polygon Mainnet from the suggested networks. This is the safest route because the values come from MetaMask itself.
- Enter it manually. Choose “Add a network manually” and paste the values from the table above. MetaMask queries the RPC and warns you if the chain ID it returns doesn't match 137.
On the MetaMask mobile app the flow is the same, but the one-click button only works inside MetaMask's built-in browser, because a normal mobile browser has no wallet injected. If you already have Polygon saved with polygon-rpc.com as the RPC, edit the network and add one of the working endpoints, then set it as the default.
Adding Polygon to Trust Wallet, Rabby, Ledger Live and others
Most modern wallets support Polygon PoS out of the box, so “adding” it usually means switching it on rather than typing values.
Trust Wallet
Polygon is built in. Search “Polygon” or “POL” in the token list and toggle it on. Your address is the same 0x address you use for Ethereum.
Rabby
Rabby detects Polygon automatically and switches network when a dApp asks for chain 137. Custom RPCs can be set in the network settings.
Ledger Live
Polygon accounts appear as a separate account in Ledger Live. Ledger's own instructions tell you which device app to install; follow the current version of those.
Coinbase Wallet, OKX Wallet, Rainbow
All list Polygon as a supported network. Check the network badge on each asset before you send.
For any other EVM wallet, look for a “custom network” or “add chain” option and use the same five values. Hardware wallets connected to MetaMask or Rabby don't need separate Polygon settings; the software wallet handles the network, the device only signs.
What the block explorer URL field actually does
People worry about this field more than they need to. The block explorer URL doesn't change your balance, doesn't send data to the explorer and has nothing to do with security. It's just a template. When you tap “View on block explorer” after a transaction, the wallet takes that base URL and appends /tx/ plus your hash, or /address/ plus your address.
That's why the URL must be the explorer's root with no trailing path, like https://polygonscan.com. Paste https://polygonscan.com/tx/ and your links break. You can point it at Blockscout (https://polygon.blockscout.com) if you prefer an open-source explorer; both follow the same /tx/ and /address/ pattern. For a head-to-head on which explorer to pick, see our ranking of Polygon explorers and the individual reviews of PolygonScan and Blockscout.
There's no single “official” explorer URL. Polygon's documentation lists several ecosystem explorers, and PolygonScan is simply the de facto default that wallets use. Our own tool at polygon-explorer.org isn't meant to go in that field; it's for quick lookups and shareable receipts.
How to check you're on the right network
Most “my tokens disappeared” messages we get come down to a wrong network. A few checks save a lot of stress:
- Look at the chain ID in your wallet settings, not just the name. Anyone can call a network “Polygon”. Only chain 137 is Polygon PoS mainnet.
- Check the gas token. Mainnet fees are paid in POL and cost fractions of a cent; our Polygon gas tracker shows live gwei prices. If your wallet asks for ETH, you're on Ethereum or zkEVM.
- Look up your address. Paste it into the Polygon address explorer. If the balance there matches your wallet, the wallet is reading the real chain.
- Match the withdrawal network. When moving funds from an exchange, choose “Polygon” or “Polygon PoS”, never ERC-20 on Ethereum, unless you mean to. If you need POL or USDC in the first place, buy it on a regulated exchange that holds licences in several jurisdictions and supports direct withdrawals to Polygon PoS, then confirm the network before you press withdraw.
Stablecoins deserve extra care because the same ticker exists as several contracts. Native USDC on Polygon PoS is 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359; the older bridged USDC.e is a different token. Our USDT and USDC explorer guide lists every official contract.
Fake RPCs and phishing “network add” pop-ups
A malicious RPC can't steal your keys, but it can lie to you. It can show fake balances, hide pending transactions, log your IP address alongside your wallet address, or refuse to broadcast your transaction while pretending it went through. Scam sites also trigger “add network” pop-ups with an RPC they control, sometimes with a wrong chain ID so that signed transactions are replayed elsewhere.
Other red flags: a “support agent” in a chat telling you to change your RPC to fix a stuck transfer, sites offering “boosted” or “private” RPCs that need your seed phrase, and tutorials that list endpoints no one maintains. A legitimate RPC never needs your seed phrase or private key. If a transaction looks stuck, check it on a public explorer before changing anything; our transaction checking guide walks through what each status means.
The polygon-rpc.com auth error and other dead endpoints
For years, https://polygon-rpc.com was the endpoint in almost every tutorial and many wallet presets. When we tested it on 25 September 2026 it returned an authentication error stating that the tenant was disabled, so it no longer works as a free public RPC. If your wallet shows balances that never update, transactions that fail with a vague “internal JSON-RPC error”, or a script that suddenly throws 401 or 403 responses, check whether it still uses that URL.
The fix takes a minute: edit the Polygon network in your wallet, add https://polygon-bor-rpc.publicnode.com or https://polygon.drpc.org, and make it the default. The same applies to Ankr's public endpoint, which now requires a key. For current official guidance on node providers, the Polygon documentation keeps an updated list, and our API page explains when a free endpoint stops being enough.
Public endpoints are shared by thousands of users, so short outages and rate limits happen. Keeping two RPC URLs saved, as the “Add to wallet” buttons above do, means your wallet can fall back automatically.
