 # GRY.PH NFT Smart Contracts
 
-The contract defined here are to allow auditors to evaluate the contracts that
-are designed and specifically for the purpose of the GRY.PH project. It
-specifies the process of digitizing collectable designs. Some of the business
-requirements include the following.
-
- - Ability to cheaply define a set of tokens that can be minted for each design which include the following.
-   - Design information
-   - Token quantity limits
-   - Royalty Fees
- - Ability to mint tokens cheaply or,
-   - Ability to facilitate air drops off chain and,
-   - Ability for buyers to redeem air drops and pay the minting costs.
- - Ability for holders to list tokens in a decentralized manner and,
-   - Ability for buyers to purchase listed tokens on any NFT marketplace while having,
-   - Ability to distribute royalties no matter where it was exchanged
-
-# Considerations
-
- - Use ERC1155 instead of ERC721
- - Use Enjin or Polygon instead of Ethereum
- - Rarible Compatibility
-
 #### Compatibility
 
 Solidity ^0.8.0
 
- - Recommended v0.8.4
+ - Recommended v0.8.9
