Anyone can start a party by simply clicking “Start a Party” and pasting the link to the NFT. See supported marketplaces here.
Anyone can join a party by contributing any amount of ETH. PartyBid automatically tracks all contributions.
Once the party has enough ETH, it can place bids in auctions or make buy now purchases.
The NFT is automatically fractionalized. Users claim fractional tokens proportional to the amount of ETH they contributed to the winning purchase.
Fractions allow users to vote on the NFT’s new reserve price.
