OpenSea.io is the largest NFT marketplace by trading volume. Built on the Ethereum blockchain, it offers various NFT types, including artwork, collectibles, domain names, in-game items, and more.
One of OpenSea’s key features is that it supports over 150 cryptocurrencies as a payment method. This makes it easy for investors to buy and sell NFTs using their crypto balances. OpenSea also supports 14 different crypto wallets and linking a wallet to the marketplace is straightforward.
In terms of fees, OpenSea charges a 2.5% transaction fee to sellers when their NFT sells, with no costs to the buyer (other than standard Ethereum network fees).
