Summary: Polygon, an Ethereum scaling solution, can be added to MetaMask via ChainList (Chain ID 137) or manual setup.
Built for fast, low-cost transactions, Polygon scales Ethereum with PoS consensus and zkEVM. Its ecosystem supports DeFi, gaming, and enterprise use while remaining fully EVM-compatible.
ChainList is the most trusted aggregator of EVM-based Layer 1 and 2 networks. It allows users to instantly connect their MetaMask to verified Chain and Network IDs, ensuring a safe connection.

Can I Add Polygon to MetaMask?
Yes, you can add Polygon’s PoS network to MetaMask as a custom network. This enables access to Polygon-based dApps, asset trading, and low-cost transactions.
To connect, enter the correct RPC details in MetaMask. Once set up, your wallet can send and receive assets on Polygon while remaining Ethereum-compatible.
How to Add Polygon to MetaMask
You can easily connect Polygon to MetaMask since it’s an EVM-compatible network. The best way to do this is by manually entering the official RPC details or using a trusted platform like ChainList.
Steps to Add Polygon via ChainList:
- Go to ChainList: Open ChainList and link your MetaMask wallet.
- Find Polygon: Type “Polygon” in the search bar.
- Add the Network: Select the correct Polygon network and click “Add to MetaMask.”
- Approve the Connection: Follow the prompts in MetaMask to confirm and complete setup.

Polygon RPC and Chain ID
To manually add Polygon to MetaMask without using tools like ChainList, enter the following network details:
- Network Name: Polygon LlamaNodes
- RPC URL: https://polygon.llamarpc.com
- Chain ID: 137
- Currency Symbol: POL
- Block Explorer: https://polygonscan.com
Always verify the latest network settings through Polygon’s official documentation to ensure accuracy.
About Polygon
Polygon is an Ethereum scaling solution that boosts transaction throughput and lowers costs. Its PoS chain operates as an EVM-compatible Layer 2, with Heimdall for consensus and Bor for execution.
Transactions settle off-chain before finalizing on Ethereum via checkpoints, ensuring security and interoperability. Polygon is shifting to a ZK-validium model, integrating zkEVM for greater efficiency and Ethereum-native compatibility, advancing its Layer 2 network vision.

Final Thoughts
Adding Polygon to MetaMask is a quick process that unlocks access to its fast, low-cost ecosystem while maintaining Ethereum compatibility. Whether you connect manually or through ChainList, ensuring you use the correct RPC details is essential for a secure setup.
As Polygon evolves with ZK technology, staying updated on network improvements will help you maximize its benefits for DeFi, gaming, and other dApps.
