MetaMask is one of the most popular crypto wallets for interacting with decentralized applications (dApps) on Ethereum and EVM-compatible blockchains. Integrating the Polygon network into MetaMask unlocks access to its fast, low-cost Layer 2 solutions. This guide covers everything from setup to advanced usage.
Key Takeaways
- Polygon is a leading Ethereum Layer 2 scaling solution with 7,000+ TPS and $0.001 average fees.
- Adding Polygon to MetaMask requires manual RPC configuration.
- MATIC tokens are needed for gas fees on Polygon.
- Polygon significantly outperforms Ethereum L1 in speed and cost efficiency.
What Is Polygon?
Polygon (formerly Matic Network) is a proof-of-stake sidechain that processes transactions off-chain while periodically committing checkpoints to Ethereum for security.
Core Benefits
✅ High throughput: 7,000+ TPS vs. Ethereum’s ~15 TPS
✅ Ultra-low fees: Average $0.001 per transaction
✅ EVM compatibility: Supports all Ethereum tooling
✅ Growing ecosystem: 750+ dApps including OpenSea and Aave

Step-by-Step: Adding Polygon to MetaMask
1. Set Up MetaMask
- Install the MetaMask browser extension.
- Create a wallet and securely store your seed phrase.
- Fund your wallet with ETH for initial transactions.
2. Add Polygon Network
- Open MetaMask and click the network dropdown.
- Select “Custom RPC”.
- Enter these details:
| Field | Value |
|-------|-------|
| Network Name | Polygon |
| RPC URL | https://polygon-rpc.com/ |
| Chain ID | 137 |
| Currency Symbol | MATIC |
| Block Explorer | https://polygonscan.com |
- Click “Save”.
Acquiring MATIC Tokens
To transact on Polygon, you’ll need MATIC for gas fees:
- Buy MATIC on exchanges like Coinbase (ERC-20 network).
- Withdraw to your MetaMask Ethereum address.
- Bridge to Polygon using the PoS Bridge.
Pro Tip: Always keep a small MATIC reserve to avoid failed transactions.
Benchmark: Polygon vs. Ethereum
| Transaction Type | Ethereum Fee | Polygon Fee |
|------------------|-------------|------------|
| Token Transfer | $20 | $0.0001 |
| ERC-20 Approval | $50-$80 | $0.001 |
Polygon reduces costs by 100-1,000x while maintaining sub-5-second finality.
Troubleshooting Common Issues
❌ “No MATIC Balance”
- Ensure you’re on the Polygon network.
Manually add MATIC token:
- Contract:
0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270
- Contract:
❌ “dApp Not Loading”
- Refresh the page and reconnect MetaMask.
- Confirm the dApp supports Polygon.
FAQs
Q: Is Polygon safe?
A: Yes, it uses Ethereum’s security model with PoS validators and checkpointing.
Q: Can I use my existing MetaMask wallet?
A: Absolutely! Just add the Polygon network settings.
Q: How do I bridge assets back to Ethereum?
A: Use the Polygon Bridge – expect ~45-minute processing.
