Is there some generic bridge support to allow xdai user to swap token minted on the xdai chain into the ethereum mainnet.
For example let say I built some ERC721/ERC20/ERC1155 smart contracts on both xdai and eth mainnet. Could I for example relies on the validator signature in some way to let users swap token between the two so they can start using their NFT on the mainnet ?
Is there already some work done on that front?
Could validator provide this kind of service with their node?
