# Introduction

## What is CoiNFT?

**CoiNFT = Coin x NFT, which is a type of token(ERC20) with a built-in NFT(ERC721)**, also known as [HIP-404](https://docs.hyppies.io/hip-404-the-mixed-ft-nft-standard) on HyperLiquid.

Technically, HIP-404 is a mixed FT/NFT standard for semi-fungible tokens, combining features of both fungible and non-fungible tokens. This allows assets to switch between states of fungibility based on the application, enabling flexible token design and use cases like NFT fractionalization and liquidity pooling.

**Today, we bring it to HyperLiquid!**

## Why CoiNFT?

CoiNFT takes your token to the next level by combining culture and identity with real utility.

Instead of just another meme coin, your project gets a built-in NFT collection, making every token more than just a number—it becomes a symbol of a community.

With CoiNFT, every token launch becomes a story, every holder becomes a part of the movement, and every trade carries meaning.
