PayPal (NASDAQ:) made major progress toward creating its own blockchain ecosystem by filing a patent application for a nonfungible token (NFT) purchase and transfer system. The application, filed in March and published Sept. 21, describes a means of carrying out transactions with NFTs, both on- and off-chain.

The patent application, which is still pending, describes a system where users can buy and sell NFTs through a third-party service provider. That provider is not specified, though is mentioned in the text.
