Blockchain platform Harmony has announced that the Bored Ape Yacht Club Passport is ready to go. Passport allows users to import their NFT proofs into Defi Kingdoms, a play-to-win game built on the Harmony blockchain and boasting over 120,000 monthly active users.

When NFT holders link their MetaMask wallets to Defi Kingdoms, they will be able to verify and demonstrate their in-game assets across multiple blockchains. Harmony's Passport guarantees end-to-end authenticity by proving users' ownership of assets across multiple blockchains. Leo Chen from Harmony said:

   “We wanted to provide more contribution and more options for all NFT holders to join the Metaverse with their NFT. Bored Ape Yacht Club owners are among the first to try it out. The cross-chain identity option is a safe and secure way to do this without risking their assets. It offers an easy way."

Another development regarding NFTs came from the social media giant Twitter last month. Twitter has announced a development that allows paid subscribers to display their NFT as their profile picture, the technical part of which is still in the testing phase. Twitter currently only supports static images such as JPEG and PNG files created on the Ethereum blockchain, and NFTs with the ERC-721 and ERC-1155 token standards.

When and how did NFT come about?

The first NFTs were based on Ethereum and appeared around 2015. The growing interest in the market for NFTs has led to increased speculation as the same investors who previously speculated on cryptocurrencies began buying and selling NFTs in massively increasing volumes. NFTs are often used to buy and sell digital artworks and can take the form of GIFs, tweets, virtual trading cards, images of physical objects, game skills or skins, virtual real estate, and more.
