Cryptokitties was only the beginning of a larger adoption of the ERC721 standard to other sector of the real economy. Since, many projects are being prepared.

The standard was launched at the end of 2017 and introduces a new function within smart contracts by making it easy to exchange unique tokens known as “non-fungible”tokens. All ERC20 tokens are identical (fungible) in the sense that one token can replace another. In contrary, an ERC721 token is unique; it corresponds to the possession of a specific asset.

One token, one property

This new standard can represent the property of a physical or digital asset, its first and most famous use case being CryptoKitties. Let’s get back to this phenomenon. It was a great topic of discussion in the cryptocurrency community, this online game has made a splash this winter thanks to its fun concept.

Cryptokitties use case

CryptoKitties uses the ERC-721 standard to provide Internet users with collectible digital cats.

The implemented concept of crypto kitties is to exchange digital cats peer-to-peer using the blockchain. Each cats is represented by one ERC721 token and each token has a specific price that also fluctuate regarding the offer and demand.

Each animal is unique so that its value is its own. The dazzling success of the application showed the ERC721’s interest in the world of gaming and digital collectible assets, but it’s just one of many use cases.

ERC721 applications

Blockchain models using ERC721 is said to develop strongly, in other sectors such as:

-Real Estate

-The art trade

-Loan financing and other financial products

In fact, the ERC721 tokens are perfect for physical assets such as land.

The Fieldcoin project combines two types of tokens in its eco-system. On the one hand, unique ERC721 tokens, each corresponding to a land plot, and on the other, enhanced ERC20 tokens used for trading on its platform.
