If you’ve ever used the Ethereum network (ERC-20), you’re likely familiar with gas fees—the transaction costs that fluctuate based on network congestion. Sometimes they’re bearable; other times, they’re shockingly high. With the growing popularity of NFTs and platforms like OpenSea requiring ETH for transactions, many users are looking for cost-effective ways to access ETH on low-fee networks like Polygon.
But here’s the catch: simply transferring ETH from Ethereum to Polygon isn’t always straightforward—or cheap. In this guide, we’ll walk you through a smart, budget-friendly method to obtain ETH on the Polygon chain without paying excessive fees. We’ll also explain the underlying mechanics so you understand why this process works and how to avoid common pitfalls.
Understanding Cross-Chain Transfers: Why Can’t I Just Send ETH?
You might be wondering: “If it’s all ETH, why do I need to ‘cross’ chains?” Great question.
Blockchains operate as independent networks. Even though Ethereum (ETH) exists on multiple chains, each version is native to its respective network. For example:
- ETH on the Ethereum mainnet
- ETH on the Polygon PoS chain
These are technically the same asset but exist in separate ecosystems. To move assets between chains, you need a bridge—a protocol that securely transfers data and value across blockchains.
While bridges make cross-chain transfers possible, they often come with high gas fees when interacting with the Ethereum mainnet. That means even if Polygon itself has low transaction costs, initiating a bridge transfer from Ethereum can still cost several dollars in gas.

The Smart Way to Get ETH on Polygon
Instead of paying high gas fees to bridge ETH directly, there’s a more economical alternative:
- Acquire MATIC (Polygon’s native token) on a centralized exchange
- Withdraw MATIC directly to the Polygon network
- Swap MATIC for ETH on a decentralized exchange (DEX) like QuickSwap
This method avoids expensive Ethereum mainnet transactions entirely and leverages Polygon’s low-cost environment from the start.
Why This Works:
- MATIC can be withdrawn directly to the Polygon network from supported exchanges.
- Once on Polygon, swapping MATIC for ETH costs only a fraction of a cent in gas.
- No need to interact with the Ethereum mainnet until absolutely necessary.
Step-by-Step Guide: Getting Started
1. Add the Polygon Network to MetaMask
MetaMask doesn’t include the Polygon network by default. You’ll need to add it manually.
- Visit the official Polygon Wallet site.
- Click “Connect to a Wallet” and select MetaMask.
- Approve the connection request in your wallet.
- On the Polygon dashboard, click “Switch to Polygon”.
- If prompted, approve adding the Polygon network to MetaMask.
- Confirm the switch when asked.
After this one-time setup, your MetaMask will have Polygon listed as an available network.
💡 Tip: The network may appear as “Matic Mainnet” in older versions—this is the same as Polygon.
Now you’re ready to receive funds on the Polygon chain.
2. Use a Supported Exchange to Withdraw MATIC
Not all exchanges support withdrawing MATIC on the Polygon network. Some only offer ERC-20 withdrawals, which send tokens to the Ethereum mainnet—not what we want.
Currently, Binance is one of the most reliable options that supports direct MATIC withdrawals to the Polygon network.
Here’s how:
- Deposit any cryptocurrency (e.g., USDT via TRC-20 for low fees) into your Binance account.
- Trade it for MATIC.
Withdraw MATIC to your MetaMask address.
- Crucially, during withdrawal, select “Polygon” as the network.
- Never choose ERC-20 unless you intend to stay on Ethereum.
⚠️ Warning: MetaMask addresses are compatible across both networks, so sending to the wrong chain won’t trigger an error—but your funds could be lost or require complex recovery steps.
Binance charges just 0.1 MATIC (~$0.15–$0.16 at current prices) for each withdrawal, making it highly cost-effective.

3. Swap MATIC for ETH on QuickSwap
QuickSwap is a leading decentralized exchange (DEX) built on Polygon. It allows seamless token swaps with near-zero gas fees.
Steps:
Go to QuickSwap and connect your MetaMask.
- Make sure your wallet is set to the Polygon network.
Click “Select a token”, search for ETH, and select it.
- If it's your first time, click the + icon to add ETH to your wallet interface.
- Enter the amount of MATIC you’d like to swap.
- Review the estimated output and fees (paid in MATIC).
- Click Swap, then confirm the transaction in MetaMask.
The swap typically confirms within seconds. Once complete, you’ll see ETH appear in your MetaMask balance under the Polygon network.
You can now use this ETH for NFT purchases on OpenSea or other dApps on Polygon.
Cost Breakdown: Total Fees Comparison
| Step | Estimated Cost |
|---|---|
| Deposit USDT (TRC-20) to exchange | $1–$2 |
| Trade USDT → MATIC | Minimal (typically 0.1%) |
| Withdraw MATIC to Polygon | 0.1 MATIC (~$0.15) |
| Swap MATIC → ETH on QuickSwap | < 0.01 MATIC |
✅ Total cost: Under $2.50, mostly from initial deposit fees
❌ Direct bridge from Ethereum: Often $5–$15+ in gas
Clearly, this method saves significant money—especially for small transfers.
Frequently Asked Questions (FAQ)
Q: Can I send ETH directly from Ethereum to Polygon using a bridge?
A: Yes, but gas fees on Ethereum can exceed $10 during peak times. For small amounts, this makes bridging inefficient.
Q: Is swapping MATIC for ETH on QuickSwap safe?
A: Yes. QuickSwap is a well-established DEX on Polygon with audited smart contracts and strong community trust.
Q: Will my MetaMask address work on both Ethereum and Polygon?
A: Yes—the address format is identical. However, always ensure you're using the correct network when sending funds.
Q: What happens if I withdraw MATIC to ERC-20 instead of Polygon?
A: Your funds will arrive on the Ethereum mainnet, where gas fees are much higher. You’d then need to bridge them manually—which defeats the purpose of saving fees.
Q: Can I reverse a mistaken network selection?
A: Not automatically. If you send tokens to the wrong chain, recovery depends on exchange support or manual bridging—often costly and complex.
Q: Are there alternatives to Binance for withdrawing MATIC to Polygon?
A: A few smaller exchanges offer this feature, but Binance remains among the most accessible and reliable globally.
Final Thoughts and Next Steps
Getting ETH on Polygon doesn’t have to be expensive. By leveraging centralized exchanges that support direct withdrawals to Polygon and using efficient DEXs like QuickSwap, you can minimize fees and maximize value.
Whether you're diving into NFTs, yield farming, or exploring Web3 apps, understanding cross-chain mechanics empowers you to make smarter financial decisions in the crypto space.
