Polygon Network Address – Frequently Asked Questions

What is a Polygon network address?

A Polygon network address is a unique identifier on the Polygon blockchain that starts with 0x followed by 40 hexadecimal characters. It is used to send, receive, and store POL tokens and ERC-20 assets on the Polygon PoS network. Because Polygon is EVM-compatible, your Ethereum address and Polygon address are identical.

How do I get a Polygon network address?

Install a compatible wallet such as MetaMask or Trust Wallet, create an account, and add Polygon Mainnet (Chain ID 137, RPC https://polygon-rpc.com). Your wallet automatically generates a Polygon network address from your seed phrase.

What is the Chain ID for Polygon?

The Chain ID for Polygon Mainnet is 137. In hexadecimal, this is 0x89. Always use this value when manually configuring Polygon in MetaMask or other wallets.

What is the RPC URL for Polygon?

The official public RPC URL for Polygon Mainnet is https://polygon-rpc.com. Alternative reliable endpoints include https://polygon.llamarpc.com and https://1rpc.io/matic.

Is my Polygon address the same as my Ethereum address?

Yes. Both Ethereum and Polygon use the same address format derived from your private key. Your 0x address works on both networks, but balances are separate – tokens held on Ethereum do not automatically appear on Polygon unless bridged.

How do I send tokens to a Polygon network address?

Open your wallet, go to "Send" or "Transfer", select the Polygon network (Chain ID 137), paste the recipient's Polygon address, set the amount, and confirm. Ensure you have a small amount of POL in your wallet to cover gas fees.

What happens if I send tokens to the wrong network?

If you send Polygon tokens to an Ethereum address using the Ethereum network, the funds may be lost or recoverable only through a bridge. Always verify the network is set to Polygon (Chain ID 137) before confirming a transaction.

How do I check my Polygon address balance?

Visit polygonscan.com and enter your 0x address in the search bar. PolygonScan will display your POL balance, ERC-20 token holdings, and full transaction history on the Polygon network.

What gas token do I need for Polygon transactions?

All transactions on the Polygon network require POL (formerly MATIC) to pay gas fees. Keep a small amount of POL in your Polygon network address to ensure you can always complete transactions and interact with dApps.

Is Polygon PoS the same as Polygon zkEVM?

No. Polygon PoS (Chain ID 137) and Polygon zkEVM (Chain ID 1101) are separate networks within the Polygon ecosystem. Both use the same address format, but they have different RPC URLs, explorers, and transaction histories. Most users on Polygon today use Polygon PoS.
