# TEP-721

## What is TEP-721 ?

***TEP-721*** is a token standard for non-fungible tokens (NFTs) on the TAN-chain blockchain. Similar to ERC721 on Ethereum,  TEP-721  defines a set of rules and behaviors for implementing NFTs, allowing developers to create unique digital assets that are indivisible, distinguishable, and provably scarce.

## Key Features of TEP-721

* **Non-Fungible Tokens (NFTs) :** TEP-721 tokens are non-fungible, meaning each token is unique and cannot be replaced or exchanged on a one-to-one basis like cryptocurrencies. Each token represents a distinct digital asset, such as artwork, collectibles, or in-game items.
* **Indivisibility :**  TEP-721  tokens are indivisible, meaning they cannot be divided into smaller units like fungible tokens (e.g., cryptocurrencies).
* **Ownership and Transferability :**  TEP-721  tokens allow for ownership transfer between addresses on the TAN-chain blockchain. Ownership is tracked on-chain, providing transparent and immutable records of token ownership history.
* **Metadata and URI :**  TEP-721  tokens can optionally include metadata, such as descriptions, images, or other attributes that provide additional information about the token and its associated digital asset.
* **Approval and Operator :**  TEP-721  tokens support token approval and operator functionalities, allowing token owners to grant specific addresses permission to transfer tokens on their behalf.

## Use cases

* **Digital Art and Collectibles :**  TEP-721  tokens can be used to represent digital art pieces, collectible items, and limited edition assets.
* **Gaming Assets and Items :** In gaming,  TEP-721  tokens can represent in-game assets, characters, skins, weapons, and other virtual items.
* **Real Estate and Property Ownership :**  TEP-721  tokens can tokenize real-world assets such as real estate properties, land parcels, and luxury goods.
* **Digital Identity and Credentials :**  TEP-721  tokens can be used to tokenize event tickets, concert passes, festival tickets, and VIP access passes. Organizers can issue  TEP-721  tokens as digital tickets, allowing attendees to securely purchase, transfer, and redeem tickets on the blockchain.
* **Intellectual Property and Licensing :**  TEP-721  tokens can represent intellectual property rights, copyrights, patents, and licenses for digital content and creative works.

## Deploying  TEP-721  Token Contracts
