Polygon Nightfall Docs
Welcome to the documentation site of the Polygon Nightfall project.
Polygon Nightfall is an upgraded version of Nightfall aimed to lower the transaction cost of ERC20, ERC721 and ERC1155 token private transfers. It uses Optimistic Rollup for lowering the costs and the privacy is attained by leveraging zero knowledge proofs. The optimistic rollup contracts are deployed on Ethereum (Layer 1). Proposers will roll up transactions into blocks and submit them to the Optimistic contracts. Challengers will submit fraud proofs for any invalid block to the same contracts. All the information required to perform a private transfer exists with clients and does not rely on any off-chain third party.
