With over 1.6 million active users, OpenSea is currently the largest marketplace to buy, sell, and trade non-fungible tokens (NFTs).
Originally, OpenSea’s platform was based solely on Ethereum, but they have since implemented Polygon PoS, to solve various issues that users face on the blockchain.
Ethereum is still the place to be for those looking to launch NFTs or build decentralized platforms. While ETH is still a wonderful choice for devs, it does come with some drawbacks.
It’s rather common for ETH users to encounter slow transaction times, high gas fees and a good deal of network congestion considering the chain is so widely used.
With Polygon’s sidechain technology, transaction times are faster and gas fees are nearly non-existent. Polygon can be implemented into all ETH-based applications and OpenSea has even implemented it.
Thanks to Polygon, users can experience a more seamless purchasing process, within this already widely popular marketplace.
Follow the guide below and you will be buying NFTs on Polygon in no time.
Your wallet will thank you…
If you wish to purchase an NFT on OS(OpenSea) using Polygon, you’ll first need to bridge ETH over to the Polygon network.
Thankfully, you can bridge your ETH right inside of OS!
After completing the conversion, you will see your newly converted ETH (Polygon) inside your wallet connected to OpenSea.
It should be noted that you will need to pay a gas fee in order to bridge the funds, but thankfully you will only need to do this once.
Your freshly converted ETH funds will remain on Polygon, unless you bridge them back. For this reason, it might be wise to move a larger sum of money over, to avoid having to bridge funds every time you wish to buy another NFT.
Now that your funds are available, it’s time to hit the marketplace.
There are two easy ways to find Polygon NFTs.
When browsing for NFTs, bring your attention to the side panel that lists filtering options. Below the “Price” and “Collections” filter tabs, you will see an option called “Chains”. Click the “Chains” option and select “Polygon” from the dropdown.
Now your browser will only populate Polygon compatible NFTs.
Other than using the filter, you can also look out for the purple hexagon.
All NFTs available for purchase on Polygon will have a purple hexagon (the ETH symbol) in place of the typical gray/black ETH symbol, or magenta WETH (wrapped ETH).
See the picture below for reference.
Buying is similar to making a purchase with ETH, only that you’ll be doing so with Polygon-based ETH.
Also, make sure to have some MATIC tokens in your wallet to cover the small gas fee.
Congrats on your new Crypto Unicorn 😉
If you would like to sell your NFTs, the process is quite similar to how you’d buy an NFT using ETH. When listing your NFT you will just need to switch your wallet to the Polygon Network, in order to sign off on the transaction.
Also, please remember that if your NFT was previously bought on Polygon, it will need to also be SOLD on Polygon.
Make sure you have MATIC tokens in your wallet to cover the transaction fees (just like when you bought).
According to Dune Analytics, Polygon’s total users over time on OpenSea, have increased from about 2,000 users in July of 2021, (when the service first became available) to over 1.2 million users in April of 2022.
OpenSea users are realizing the massive value add that Polygon provides, and as mass adoption of NFTs spreads, Polygon’s scaling solutions will only become increasingly necessary for sustainability.
