Adding USDC on the Polygon network to your MetaMask wallet unlocks access to faster transactions and lower fees within the growing Polygon DeFi ecosystem. This guide provides clear, step-by-step instructions to help you integrate this popular stablecoin seamlessly.
Prerequisites
Before you begin, ensure you have the following ready:
- A MetaMask wallet installed in your browser or on your mobile device.
- Some MATIC tokens in your wallet to pay for network (gas) fees. You cannot add tokens or interact with the Polygon network without MATIC.
- USDC tokens on the Polygon network in an exchange account or another wallet ready to be sent.
Step-by-Step Guide to Adding USDC Polygon
1. Switch to the Polygon Network
First, you must configure MetaMask to connect to the Polygon network.
- Open your MetaMask wallet extension or app.
- At the top of the window, click on the network dropdown (it likely says "Ethereum Mainnet").
- Select "Add Network" or "Add a network manually" from the list.
Enter the following Polygon Mainnet details exactly:
- Network Name: Polygon Mainnet
- New RPC URL:
https://polygon-rpc.com/ - Chain ID:
137 - Currency Symbol: MATIC
- Block Explorer URL:
https://polygonscan.com/
- Click "Save". Your MetaMask is now connected to the Polygon network.
2. Add USDC as a Custom Token
Even after switching networks, you often need to manually add the token contract to make your USDC balance visible.
- While on the Polygon network in MetaMask, click "Import tokens".
- Go to the "Custom Token" tab.
In the "Token Contract Address" field, paste the official USDC Polygon contract address:
0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174- Crucial Warning: Always verify this address from an official source like the Polygon blockchain explorer (Polygonscan) to avoid scams. Other fields should auto-populate.
- The "Token Symbol" should show "USDC" and "Decimals of Precision" should be 6.
- Click "Add Custom Token" and then confirm the import.
Your USDC balance on the Polygon network will now be visible in your MetaMask asset list.
3. Receiving USDC Polygon
To receive USDC on Polygon, simply share your MetaMask wallet address with the sender. Double-check that the sender is withdrawing to the Polygon network (not Ethereum or another chain) on their exchange or platform to prevent permanent loss of funds.
Why Use USDC on Polygon?
Integrating USDC on Polygon into your wallet offers significant advantages:
- Low Transaction Fees: Gas fees on Polygon are a fraction of a cent, making small transfers and DeFi interactions economically feasible.
- High Speed: Transactions are confirmed in seconds, providing a smooth user experience.
- DeFi Access: Gain entry to a vast ecosystem of Polygon-based decentralized applications (dApps), including lending protocols, decentralized exchanges (DEXs), and yield farming opportunities.
- Stable Value: As a stablecoin pegged to the US dollar, USDC provides a safe haven from crypto market volatility while remaining digitally native.
Troubleshooting Common Issues
- Balance Not Showing? Ensure you are on the correct "Polygon Mainnet" in your network list and that you have successfully imported the token using the correct contract address.
- No MATIC for Gas? You must acquire MATIC tokens first. You can buy them on an exchange and withdraw them to your Polygon wallet address, or use a MATIC faucet for a small amount to get started.
- Transaction Stuck or Failed? This is often due to too low of a gas fee. You can usually adjust the gas settings or simply try the transaction again.

Frequently Asked Questions
What is the official USDC contract address for Polygon?
The official USDC contract address on the Polygon network is 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174. It is critical to copy this address directly from a verified source like the Polygonscan block explorer to avoid sending funds to a malicious contract.
Why do I need MATIC tokens to add USDC?
MATIC is the native cryptocurrency of the Polygon network. It is used to pay for transaction fees (gas), including the computational effort required to add a new token to your wallet's interface. Without MATIC, you cannot perform any actions on the network.
Can I send USDC from Ethereum directly to my Polygon address?
No, you cannot send tokens directly across different blockchains. You must use an official bridge. For example, you can use the Polygon Bridge to move USDC from the Ethereum network to the Polygon network. Sending directly to an address on another chain will result in lost funds.
Is there a difference between USDC on Ethereum and USDC on Polygon?
While both tokens represent the same stablecoin value (pegged 1:1 with the USD), they exist on separate blockchains. They are not natively compatible. You must bridge them to move value between the Ethereum and Polygon ecosystems.
My transaction is taking a long time to confirm. What should I do?
Polygon transactions are typically very fast. If a transaction is pending for an unusually long time, it may have been stuck due to low gas. You can try speeding it up within MetaMask or simply wait for it to eventually drop from the mempool.
How do I bridge USDC back to Ethereum if needed?
To move USDC from Polygon back to Ethereum, you would use the reverse process on the Polygon Bridge. This will require paying gas fees on both the Polygon and Ethereum networks and involves a waiting period during the challenge period on the bridge. Always view real-time tools for the most current bridge interfaces and fees.
