Sqwid is the official NFT marketplace of the Reef chain, an EVM compatible L1 built on the Substrate framework. Sqwid NFTs are ERC1155 compatible which means each one can have multiple copies. They also implement the EIP-2981 Royalty Standard, which allows creators to set a royalty percent that automatically gets transferred to their wallet whenever future sales of the NFTs happen. No extra work needed. Sqwid supports image, video, and audio NFTs and all metadata is stored on Filecoin and IPFS which means the content you’re buying or selling will never be taken down or tampered with.
