What is TopBidder?
TopBidder is an Ethereum auction protocol where each rNFT carries a self-assessed price set by its current holder under a Harberger-tax style mechanism inspired by Radical Markets. New owners can claim any rNFT by paying the standing price, with bonding-curve dynamics producing continuous price discovery and rewarding creators on every transfer.
