Bonding curve project for erc721 tokens

ERC721 & Bonding Curve

This experiment is a playground for the development of unique PROPERTY tokens for the Realestate. We use Truffle as a development environment for compiling, testing, and deploying our contracts. They were written in Solidity.

Idea

The idea is for an owner to purchase a retail PROPERTY whose price follows a bonding curve. An owner can only own one PROPERTY token, preventing anyone from gaining control of the entire mall by purchasing all the PROPERTY available

PROPERTY Token

The PROPERTY token is created in the RealestateToken.sol file. It follows a basic ERC721 implementation with nothing unique in particular.
However, to achieve the unique one-of-a-kind ownership and restriction, the ERC721 tokenID is based a keccak256 hash of the owner's address, making it impossible for an owner to mint an ERC721 token twice.

Estate Agent

The EstateAgent houses the bonding curve function as well as purchasing and selling of PROPERTY tokens.
Since the PROPERTY tokens have to be minted only when a buyer exists, the bonding curve requires a slight modification to its implementation. It allows for continuous minting of tokens but only up to a certain threshold which is declared during initialization under _currentLimit.

Rental Agent

Handles the renting of PROPERTY tokens. Each rental lasts for 1 year and will cost 1/10 of the current PROPERTY purchase price.

Admin

Handles adding/removing admins from control of the contract
