Creator Core is the set of smart contracts to create a sovereign minting contract (ERC721/ERC1155 supported). Currently, you can deploy your own Creator Core instance using Manifold Studio.
Manifold Studio currently supports the Ethereum network. However, the Creator Core contracts work with any EVM network (e.g. Polygon, Optimism, Arbitrum). To use Creator Core on any other EVM network, you will need to clone the github repo and deploy using a Solidity IDE like remix.
