The Bazaar

Overview

The entry point into the Rare Protocol ecosystem is the Bazaar. This contract unifies the previously separate Marketplace and Auction House, allowing users to only approve a single contract and give us the ability for new functionality such as converting offers into auction bids.

                    +-> Marketplace
                   /
         Bazaar --+
                   \
                    +-> AuctionHouse

This works by unifying the storage and interaction into the Bazaar with the logic for each living in the Marketplace and AuctionHouse contracts. Calls to the Bazaar are then delegated to the corresponding contract which allows the logic of the Marketplace/Auction House to be executed in the scope/state of the Bazaar.

Functionality Spec

Writes

offer(address originContract, uint256 tokenId, address currencyAddress, uint256 amount, bool convertible) -> ()

Places an offer on the ERC721 described by the given originContract and tokenId with the amount of currencyAddress. The zero address for currencyAddress corresponds to an offer in ether.

If a previous offer of the same currencyAddress exists then the new offer must be greater than minimumBidIncreasePercentage above the existing offer. The beaten offer is then refunded.

Note: Offers made with convertible set to true can be used as a reserve auction triggering bid.

Emits an OfferPlaced event.

Requirements:⟠ currencyAddress is approved via ApprovedTokenRegistry.⟠ _msgSender() approved marketplace for amount of currencyAddress.⟠ Amount sent/transfered must include amount + marketplaceFee. buy(address originContract, uint256 tokenId, address currencyAddress, uint256 amount) -> ()

Purchase an ERC721 token described by originContract and tokenId with the amount of currencyAddress. The zero address for currencyAddress corresponds to buying with ether.

A SalePrice of amount of currencyAddress must exist.

Emits a Sold event.

Requirements:⟠ The token owner must have the bazaar approved.⟠ Amount sent/transfered must include amount + marketplaceFee. cancelOffer(address originContract, uint256 tokenId, address currencyAddress) -> ()

Removes a given offer on an ERC721 token described by originContract and tokenId under the given currencyAddress and refunds the sender. The zero address for currencyAddress corresponds to an offer in ether.

Emits a CancelOffer event.

Requirements:⟠ offerCancelationDelay seconds must have passed since the offer was placed. setSalePrice(address originContract, uint256 tokenId, address currencyAddress, uint256 listPrice, address target, address payable[] splitAddresses, uint8[] splitRatios) -> ()

Sets the sale price for an ERC721 token described by originContract and tokenId of amount of currencyAddress. The zero address for currencyAddress corresponds to a sale price in ether.

This supports both general and direct sale prices through the target field where the zero address indicates a general sale price.

The splitAddresses and splitRatios correspond to the recipients of funds from a sale.

Note: Only 1 sale price for a target can exist.

Emits a SetSalePrice event.

Removes the sale price on an ERC721 token described by originContract and tokenId for a given target.

Emits a SetSalePrice event with all zero values.

Requirements:⟠ _msgSender() must be the token owner. acceptOffer(address originContract, uint256 tokenId, address currencyAddress, uint256 amount, address payable[] splitAddresses, uint8[] splitRatios) -> ()

Accepts an offer placed on an ERC721 described by originContract and tokenId for the amount of currencyAddress.

Zero address for currencyAddress means the offer was made in ether.

The splitAddresses and splitRatios correspond to the recipients of funds from a sale.

Emits an AcceptOffer event.

Requirements:⟠ currencyAddress is approved via ApprovedTokenRegistry.⟠ The token owner must have the bazaar approved.⟠ _msgSender() must be the token owner.⟠ splitAddresses and splitRatios must be the same length and the ratios must add up to 100. configureAuction(bytes32 auctionType, address originContract, uint256 tokenId, uint256 startingAmount, address currencyAddress, uint256 lengthOfAuction, uint256 startTime, address payable[] splitAddresses, uint8[] splitRatios) -> ()

Configures a fully onchain auction of an ERC721 token described by originContract and tokenId with a starting price of amount of currencyAddress. Only 1 auction per token can exist at a given time.

The splitAddresses and splitRatios correspond to the recipients of funds from a sale.

Auction Types:⟠ Reserve (Coldie): An auction that is triggered when the startingAmount is met.⟠ Scheduled: An auction with a minumum bid of startingAmount of currencyAddress that starts at startTime and runs for lengthOfAuction seconds.

The auctionType for reserve auctions is 0x434f4c4449455f41554354494f4e000000000000000000000000000000000000 and scheduled auction is 0x5343484544554c45445f41554354494f4e000000000000000000000000000000.

Note: The startTime must be 0 when the auctionType corresponds to a reserve auction.

Places a bid on an existing auction on ERC721 token originContract and tokenId for amount of currencyAddress. Beaten bids will be refunded to the previous bidder.

If a bid is placed and there is less than auctionLengthExtension seconds left then the auction ending is updated so that the legnth is equal to auctionLengthExtension.

Emits an AuctionBid event.

Requirements:⟠ An auction on the token must exist.⟠ Bidder cannot be the auction creator.⟠ Auction must have started.⟠ Bid must be greater than 0, minimumBid, or currentBid + minimumIncrease.⟠ Bid must be higher than marketplaceSettings.getMarketplaceMaxValue().⟠ Amount sent/transfered must include amount + marketplaceFee.⟠ Auction creator must be the owner or the token must be escrowed.⟠ Token owner must have the bazaar approved. convertOfferToAuction(address originContract, uint256 tokenId, address currencyAddress, uint256 amount, uint256 lengthOfAuction, address payable[] splitAddresses, uint8[] splitRatios) -> ()
