OpenSea – An Abstract

OpenSea, the largest decentralized marketplace for trading NFTs in the world, is a revenue-generating platform for creators and artists. It allows users to buy, sell, trade, mint, and hold NFTs securely on the Ethereum and Polygon blockchain networks.

Being backed by eminent crypto investors, including Mark Cuban, a16z, Ashton Kutcher, etc., OpenSea is one of the youngest NFT platforms achieving the massive feat of Unicorn status. Yes, you've guessed it right! OpenSea's valuation is more than $1 billion now.

The features and functionalities of the platform offer users a seamless and hassle-free NFT trading experience. To put it in simple terms, the web 2.0 version of OpenSea would be something similar to that of eBay, where people can list their items for sale, and buyers who require the items will have the opportunity to bid on them.

As a Web 3.0 platform, OpenSea does the same by allowing people to tokenize artworks, videos, music, in-game assets, domain names, sports collectibles, and anything that humans feel is unique in NFTs.

Requirements to Mint your NFT in OpenSea

  • A device- possibly a PC, laptop, tablet, or smartphone, with a good internet connection is mandatory. 
  • A wallet is crucial for any operation in the crypto realm. Similarly, you would require a web 3.0 wallet like MetaMask. 
  • Note that OpenSea is a marketplace that runs on robust Ethereum and Polygon networks. So your web 3.0 wallet should support Ethereum or Polygon network.

Wrapping Up

You might wonder why OpenSea didn’t charge you a penny. Yes, because they follow a mechanism called Lazy Minting. Earlier, artists had to pay for all the NFTs they mint on the platform, which may or may not get sold among NFT enthusiasts. It becomes difficult for them to pay each time when they mint an NFT. To get rid of this limitation, OpenSea introduced Lazy Minting. 

This feature will allow anyone to mint and list the NFT for absolutely free. Once any NFT admirer comes forward to buy the asset, the gas fee will be added. During the purchase of the NFT, the trading fee (commission for OpenSea), plus the gas fee, will be deducted from the total price. This late implementation of the gas fee is called lazy minting. And it is really helpful for the artists to list their masterpieces then and there without worrying about the gas fee. 

Why are you still waiting? Go create your first-ever NFT absolutely free in the OpenSea! Happy Minting!
