# Multi-Fractional Non-Fungible Token
Solidity Implementation of Multi-Fractional Non-Fungible Token.

## Problem Trying to solve
Before, ERC20 Token contract should be deployed every time when fractionalizing a specific NFT.

To solve this problem, this standard proposes a token standard to cover multiple fractionalized nft in a contract without having to deploy each time.
