SyncSwap, a zkSync-based decentralized exchange platform, announced the launch of the ERC404-inspired SyncSwap 404 Wrapper, which allows existing ERC-721 NFTs to be wrapped into ERC404 fungible wrapped tokens. 404 Wrapper is a public product of SyncSwap that operates on a completely permissionless and open source basis, with no fees for wrapping and unwrapping NFTs. LIBERTAS OMNIBUS is an experimental NFT project by the zkSync team.
