NFT services offered on the OpenSea platform

opensea nft

The OpenSea platform offers two main services: NFT exchange and NFT creation.

The NFT marketplace

OpenSea’s primary function is to offer a wide range of NFTs. So, whether you’re an investor or a collector, you can buy the NFT of your choice. The transaction occurs directly between the seller and the buyer, thanks to the blockchain technology used on OpenSea. This is known as a peer-to-peer or decentralized transaction.

To buy or sell an NFT on OpenSea, you must:

1. Open an account on OpenSea;

2. Open a crypto wallet compatible with OpenSea such as:

  • MetaMask
  • Coinbase Wallet
  • WalletConnect
  • Phantom (for NFTs hosted on the Solana blockchain)
  • Glow (for NFTs hosted on the Solana blockchain)
  • Fortmatic
  • Kaikas
  • Bitski

NFT trading volume on OpenSea

On Opensea.io, you can also create your own NFT to offer it for sale. Creating an NFT involves registering your token on the blockchain. This is known as “minting”.

The advantage of OpenSea is that anyone can create their own NFT. In fact, you don’t even need to know the main principles of ERC tokens, let alone do any computer programming. You must create your NFT (image, video, etc.) and upload it to OpenSea via the “Create” button. But be careful! Before you start creating your NFT, be sure to check OpenSea’s file size and weight constraints.

OpenSea: NFT platform fees

Fees on the OpenSea NFT platform are set at 2.5% on all secondary sales and between a 2.5% and 10% fee on mints from primary drops. In other words, the platform charges 2.5% on each transaction. NFT creators, on the other hand, can set fees of up to 10%. These Opensea fees are charged to the NFT creator every time their NFT is sold and resold.

If you create (mint) an NFT on the OpenSea App, you must also pay a gas fee. The amount of this fee depends on the blockchain used and its traffic. These fees can be exceptionally high since OpenSea works mainly with the Ethereum blockchain. Indeed, the Ethereum blockchain encounters recurring congestion problems, which causes its gas charges to soar. On OpenSea, you can put your NFT up for sale without transferring it to the blockchain. As a result, you only pay the gas costs at the time of the transaction (sale).


OpenSea is today’s leading NFT platform. The platform shines for its simplicity and low fees. Moreover, you’ll find a huge choice of NFTs in many fields: art, music, maps, domain names, etc.
