This year we\'ve fully immersed ourselves in the digital world and cryptocurrencies. As we mentioned in previous posts, NFTs and digital currencies have reshaped the landscape for digital consumers. Within this new and unfamiliar world, new businesses have emerged around the sale of assets, such as OpenSea. This platform functions as a decentralized virtual marketplace specializing in the trading of NFTs. It was launched in late 2017, the brainchild of Devin Finzer and Alex Atallah. Since then, the platform has experienced continuous growth. Currently, the platform offers more than 20 million collectible assets, or NFTs, for virtual trading. It also boasts a user base of over 2 million active users and around 200 different categories for filtering NFTs. OpenSea\'s interface was created using blockchain technology from the Ethereum virtual currency, which has recently positioned itself as the most secure cryptocurrency. However, the platform not only accepts Ethereum as its currency but also supports other blockchains such as Polygon and Klatyn. The platform features around 150 payment tokens, although the primary cryptocurrencies are WETH, USDC, and DAI. To buy or sell NFTs on OpenSea, users need a digital wallet. The most well-known is MetaMask, which is frequently used in conjunction with OpenSea. The wallet is personal, meaning you will need to validate your data and identification to connect the platforms for trading. To buy an NFT, you need to use the filters to select the categories you prefer via a search engine. Each NFT also comes with its own descriptions. Information about the creators, collections, and NFT characteristics is also provided.
