Polygon is a blockchain that provides scalable, secure, and quick transactions with Ethereum currencies like ETH, USDC, MATIC, and DAI.

Buying an NFT on Polygon requires using Polygon ETH or MATIC. In order to spend your Ethereum currencies on Polygon, you must first "bridge" them across to the Polygon blockchain.

To find items on Polygon, check Polygon under the Chains section on the left panel when browsing NFT items.

Polygon items can be identified by hovering over the item to see the Polygon logo in the upper left corner.

Buying NFTs on Polygon is just like buying NFTs on the Ethereum mainnet. Once you've found your item, click Buy now.

OpenSea supports typed signatures on Polygon, the same as we do on Ethereum, making it easier for users to understand what they are signing. In order to complete the signature request, you'll be prompted to switch your wallet network to Polygon.
