How to use Polygon layer 2 network to make payments

Payment transactions on Polygon are confirmed in sub-seconds due to faster block generation times. This provides a payment experience with immediate delivery and close to zero transaction fees.

Polygon network can be used with wallets like Metamask, Rabby, Portis, Arkane, or Torus.

What is Polygon (formerly Matic)?

Due to high demand and network congestion, some of the most popular blockchains including Ethereum have seen increasingly high transaction fees, making the use of crypto for shopping more expensive and difficult for users.

Polygon is a layer-2 network designed to bring mass scalability to Ethereum and interoperability between other blockchains. Polygon (formerly Matic) resolves high gas fees and slow confirmation times for users who shop with crypto assets like USDT, USDC or DAI, and other ERC20 tokens.

After adding the product that you want to buy to your shopping cart, simply select the currency in “USDT” and “Available network” as “Polygon”. On the payment page, you will see a Polygon wallet address you can make your payment to.

It is that easy!
