Assets

The core SuperRare protocol is asset agnostic but in order to stregthen the network we provide the community with art based tokens such as our shared ERC721 minting contracts (SuperRareV2 and SuperRareV1), creator owned minting contracts (Series), and curator owned/managed minting contracts (Spaces). On the ERC20 front, while our bazaar has the ability to support any token on the Approved Token Registry we’ll focus on the $RARE Governance token.

While the SuperRare Bazaar supports any arbitrary ERC721 token, we have gone ahead and provided a few of our own; SuperRareV1 (deprecated), SuperRareV2, Series, and Spaces.

The first version of the SuperRare ERC721 is a specal case where the market contract is built into the token allowing only offers and SalePrices and doesn’t let a user approve other operators to move tokens on their behalf (this is the reason that etherscan thinks they’re ERC20 tokens).

Note that this is a shared minting contract shared by all token creators.

In addition to the above there’s some more functionality built in:

function transfer(address _to, uint256 _tokenId)
	public;

function bid(uint256 _tokenId)
	public
	payable;

function acceptBid(uint256 _tokenId)
	public;

function cancelBid(uint256 _tokenId)
	public;

function buy(uint256 _tokenId)
	public
	payable;

function setSalePrice(uint256 _tokenId, uint256 _salePrice)
	public;

This is the current default minting contract used by the SuperRare ecosystem. Unlike the V1 token this one removes the builtin market functionality optiing for full composability.

Note that this is a shared minting contract shared by all token creators. Access to minting is controlled by SuperRare.

Additional Functionality:

The series NFT contract is an ERC721 contract supplied by SuperRare and allows artists to deploy their own ERC721 contract that is fully owned by them. We’ve adopted OpenZeppelin’s clones library to cut down on the cost of deployment by a factor of 10.

Note that this is a solo minting contract only able to be minted to by the contract owner.

Additional Functionality:

Space NFT contracts are ERC721 tokens that are the basis of our first step to decentralized curation. Under a Space NFT contract, the contract owner (often referred to as the Space Operator) can add artists to the allowlist to mint (this variation also has the concept of a minting allowance rather than being all or nothing).

Note that this is a shared minting contract shared by all token creators. Access to minting is controlled by the SpaceOperator.

Additional Functionality:

The $RARE token is the governance token (ERC20) of the SuperRare Network used to vote on SIPs (SuperRare Improvement Proposal).
