Artizen Smart Contract

The Seasons contract provides a robust infrastructure for managing digital artifacts across different seasons in a decentralized manner on the Artizen platform. It leverages the ERC1155 token standard and access control mechanisms to ensure secure and efficient operation. It allows visionaries to participate in seasons to raise funds to kickstart their projects. With features for creating submissions, managing seasons, and minting artifacts, the contract offers a comprehensive platform for artists and collectors to engage in the creation and exchange of digital art.

Functions

function setProtocolWalletAddress(address payable protocolWallet)

Use this function to set central protocol wallet address after deployment. This wallet is a multisig wallet that will store all funds.

address payable protocolWallet: address of Ethereum wallet

function setTokenPrice(uint256 price)

Sets the price of a single NFT.

uint256 price: token price in wei

function shutdown(bool isShutdown)

This is an emergency function that shuts all main functionalities of the contract in case of a security alert.

function createSeason( uint startTime, uint endTime)

Creates a season with given details.

startTime: time of the season opening, in unix timestamp
endTime: time of the season closing, in unix timestamp

function createSubmission(uint256 _season, string memory _tokenURI address payable _submissionOwner)

Creates a submission with given details.

_season: ID of season
_tokenURI: tokenURI for NFT
_submissionOwner: address of the submission owner/registered project wallet

function closeSeason(uint256 _season)

Closes a season, so there can be no more submission submitted to it. It mints the amount of each tokenID sold within the season to the protocol wallet.

_season: ID of season

function mintArtifact( uint[] memory submissionID, uint[] memory amount)

Mints given amount of open edition artifacts to buyers wallet. It records a balance for the submission owner (artist) to be able to claim their tokens as well as other calculations for the leaderboard and the top submission of the season.

submissionID: ID of submission
amount: amount to mint for user

function artistClaim( uint[] memory submissionID,uint[] memory amount)

Submission owners (artists) can claim copies of their own artifacts according to their claim balance. The maximum amount of artifacts to claim is equivalent to the maximum amount of artifacts sold at any given time. Once their claim balance is 0, they claimed all available artifacts.

submissionID: ID of submission
amount: amount to mint for user

function calculateTopSubmissionsOfSeason(uint _seasonID)

Calculates the top submission with the most open edition NFTs sold. This function doesn't return any data, you have to call getSeason or getTopSubmissionOfSeason view functions to see the results.

_season: ID of season

function withdraw()

Withdraws all ETH from the contract to the protocol wallet.
