The OpenSea NFT Marketplace

The reason for Opensea’s popularity doesn’t fall just on their reputation for being the world's first and largest NFT marketplace but for their continued interest in their community and frequent platform upgrades. From changing their Ethereum-only marketplace to a multi-chain marketplace that now supports Polygon and Klatyn to adding a feature for users to buy NFTs directly with their cards, it’s easy to see why it’s the #1 rated NFT marketplace worldwide. 

Some of the most popular NFT collections including Crypto Punks, Bored Ape Yacht Club, Metaverse, Pudgy Penguins and more were born on the OpenSea marketplace.


OpenSea Fees

As the platform is a multi-chain marketplace, we will take you through the fee’s for all three networks. OpenSea boasts some of the lowest transactions in this space by taking a 2.5% cut of every item (regardless of network) sold on their marketplace.

For the Ethereum network, you will need to pay around $10 - $100USD to cover transaction (gas) fees when purchasing or selling NFT’s. The price of gas fees can vary depending on the time of day. 

For the Polygon network, Opensea offers its users to create, buy and sell NFTs without paying transaction (gas) fees, essentially creating a gas-free marketplace. 


Supported Crypto Wallets

OpenSea has integrated with a multitude of secure crypto wallets, which means you can store NFTs in many different ways. They currently offer 15 different crypto wallets. Some of the wallets supported include:

  • MetaMask
  • Coinbase Wallet
  • TrustWallet
  • WalletConnect
  • Dapper
  • Portis 
  • Fortmatic
  • Venly
  • Authereum + many more
