ERC721-O is a standard interface and implementation for omnichain non-fungible tokens (NFT) based on ERC721.
It aims to allow third-party applications (e.g., wallet/marketplace) to interact with any token implemented in this interface uniformly.
It also enables the implementation of multiple new features and proposed solutions to mitigate security issues in the cross-chain domain.
