OpenSea – Largest marketplace for crypto goods

OpenSea.io is the first and biggest marketplace for blockchain backed assets (like eBay or Amazon, but for crypto goods), which includes NFT art collectibles, domain names, game items, trading cards and other virtual goods secured by a blockchain.

To get started with Opensea.io, simply plug in a Web3 wallet like MetaMask and you’re good to start browsing.

While average sales have a fixed price, auctions usually sell rare or unsold items, which therefore have a higher rate.
You can make an offer for crypto collectibles that are not even on sale, which is a very good feature for users who can’t simply set a price for their items. Besides, you can make an offer for more than one items with the same ETH.

It provides a one-stop shop for creating your own customizable marketplace for your ERC721 or ERC1155 non-fungible token (NFT) project. Allow users to smoothly buy and sell your items, get custom stats and analytics, and earn revenue when your items get traded.
Listing is free of charge, and if items are sold successfully, OpenSea will charge a 2.5% fee on the final sale price (and in some cases the creator gets a cut).
