What is Matcha Smart Contract?

ERC-721 is a standard for non-fungible tokens (NFT) or deeds. NFT are useful to represent digital or physical assets that cannot be divided, for example:

• Properties (houses, art pieces)
• Virtual collectibles (virtual pets, cards)
• “Negative value” assets (loans, burdens, and other responsibilities)

One of the most famous ERC-721 token is the CryptoKitties. The most expensive CryptoKitty to date is Dragon, with a price of 600 Ether (USD 232K value at the moment of writing).

But NFT is not only about kitties. There are all kinds of virtual assets. OpenSea, one of the biggest Marketplaces for NFT, has thousands of assets from Virtual Worlds to Football Fantasy Cards.

During late 2020 and 2021 the NFT market has reached incredible levels of monetization in different areas including arts, music, memes, tweets and all kinds of NFT. One of the most notable ones was the Beeple, Everydays – The First 5000 Days sold for more than 69M$
