Polygon for payers

About Polygon

The Polygon network is an Ethereum scaling solution built to provide faster, cheaper transactions. Polygon is a Layer 2 network that uses sidechains to expand Ethereum’s transaction throughput. This allows payers to make payments for a fraction of the cost of sending on Ethereum Mainnet.

Coinbase Commerce supports USDC, WETH (wrapped ETH), and MATIC payments on Polygon.

Coinbase has a number of resources for you to learn more about Polygon. Our Polygon Learn page gives you a brief overview of what it is, how it works, and how you can use it. You can also find information about Polygon on the Assets tab of the website.

This article will provide you with instructions on how to pay with USDC, WETH (wrapped ETH), or MATIC (Polygon) funds on Polygon.

Pay with funds on Polygon

When you pay with USDC, WETH, or MATIC funds on the Polygon network, you’ll pay cheaper network fees (typically a few cents) and have faster confirmation times than when you pay with these same funds on the Ethereum network.

If you’re paying for something with Coinbase Commerce and the merchant has enabled payment on the Polygon network, you can pay with funds on Polygon in two ways: 

  1. Select Pay with coinbase at checkout and follow steps to pay using your Coinbase account.

  2. If you’re using another wallet, locate the token you’d like to pay with on the Polygon network from the list of cryptocurrencies that the merchant accepts. You’ll see the Polygon icon Image showing the Polygon (MATIC) icon on the token’s tile to indicate that it’s on the Polygon network.

If you’re paying from your Coinbase account with USDC, ETH, or MATIC, the payment process will automatically configure the cheapest, fastest way to pay. That means USDC, WETH, or MATIC will be sent on Polygon if the merchant has enabled it and you will not need to manually select the network. 

Get funds on Polygon

If you’re using Coinbase to get funds on the Polygon network, you can: 

  • Buy the funds directly on the Polygon network

  • Use Coinbase's multi-chain support to send certain tokens on the Polygon network from your stored balances even if you have not purchased those tokens on Polygon.

You can also bridge funds to Polygon from your existing cryptocurrency balances, either on Coinbase or on another exchange or wallet.

Buy funds on Polygon

Many major exchanges, including Coinbase, allow you to buy cryptocurrency directly on the Polygon network. You can find instructions for buying on on our Help Center. If you're using another exchange, look for instructions on their site or help center.

Use multi-chain support

Although most assets on Coinbase are only supported on the blockchain network that hosts them (even though the asset may technically be available on multiple networks), we do offer multi-chain support for select assets.

The benefit of being able to choose from more than one network for your Coinbase transaction is that some networks may offer lower fees and higher speeds.

For assets with multi-chain support, you’ll have the option to choose which network to use when you’re sending or receiving the asset.

Note: The same network must be used on both the sending end and the receiving end unless the transaction involves the Polygon and Ethereum networks. See examples below.

You can send USDC, ETH/WETH, and MATIC on Polygon using Coinbase's multi-chain support.

  1. Sign in to Coinbase.

  2. Select Pay.

  3. Select Send, then select the token you'd like to pay with. 

  4. Enter the amount you want to send.
    Note: The amount that you send should correspond with the amount of cryptocurrency that the merchant is requesting, not the amount of local currency. This is intended to help prevent shortages or overages in your payment.

  5. Enter the address you’re sending to or scan the QR code from the merchant’s Coinbase Commerce checkout page.

  6. Preview your send and then select the Network you'd like to use to send your funds.

  7. Complete your send.

Please note that multi-chain support is not yet offered in New York or Japan.

Bridging is the term used to describe the action of moving assets from one blockchain to another.  Blockchain assets are not always compatible with each other, so blockchain bridges create derivatives (or copies) that represent an asset from another chain.

For example, if you use a bridge to send a token on the Polygon blockchain to an Ethereum wallet, the Ethereum wallet would receive a bridge version of the Polygon token that was converted to an ERC-20 token for use on the Ethereum blockchain.

Note that bridging funds across blockchains costs network fees on both chains.

The Wallet Help Center provides more general information about bridging and how to bridge with Coinbase Wallet. For bridging with other wallets, check your wallet’s help center to see which bridges are supported or visit a bridge directly.
