# Non-Fungible tokens in Venom network

Non-fungible tokens aka NFT are unique cryptographic tokens that exist on a blockchain and cannot be replicated. Non-fungible is an economic term that you could use to describe things like your picture, a song file, or even your furniture. These things are not interchangeable for other items because they have unique properties.

Venom network uses the standard of fungible tokens TIP-4

### What is TIP-4?

Same as Ethereum ERC-721 standard, TIP-4 provides similar functionality for Venom Blockchain. As well as TIP-3, TIP-4 was designed to match the distributed system design of the Venom network. It is cost-effective for it's fee-paying model.

TIP-4 provides following functionality:

* minting and burning NFTs
* transferring NFTs from one account to another
* selling your NFTs

### ERC721 differences

ERC721 generally is a monolith smart-contract, which stores mapping, that show token owners by token ids. Tokens metadata can be stored here too in another mapping or you can store only `tokenUri` (mapped the same way - by token ids), which can help you to reach token metadata.

TIP-4 consists of collection contract and personal contracts for each non-fungible token. As a results, users owns concrete amount of NFT contracts, that stores metadata.
