OpenSea's search engine and NFT analytics makes using the platform easy and painless. From linking my MetaMask to buying NFTs, everything was a one-click and done process. My only complaint is that stolen NFTs are still allowed to be sold on OpenSea and while OpenSea has done their best to flag these products, it's not enough and I believe they should ban these users from the platform, rather than letting them re-list. While the stolen NFTs can be confusing to a first time user, I do appreciate the blue check mark verification on projects. It makes me feel safe knowing that OpenSea has vetted a project to ensure that I am buying the official NFT project and not a derivative of the original.

It’s the go-to platform for NFTs, and the Polygon integration made it easy to distribute our Joey Giveaway NFTs to early backers.

I've used OpenSea for almost all of my NFT purchases. Overall my experience has been positive. However, the User Interface has been confusing when delivering error messages (such as just saying "transaction failed" with no clear indication as to why that happened) or an offer expires but still remains on my offers page. I believe OpenSea allows for people to purchase NFTs easily (even using Fiat currency) and provides overall good user experience.

Good marketplace which I think handles multi-chain relatively well - the studio stuff they've recently recently is really cool as it gives NFT projects the opportunity to really showcase their brand a lot more.

One of the first marketplace. Still pretty good. The Pro feature is a big plus.
