Non-fungible tokens (NFTs) are commonly seen as nothing more than digital art. But the utility of NFTs has the potential to go far beyond that single-use case. They can completely redefine customer experience, community engagement, and loyalty. SENTR3 is a blockchain-agnostic platform that lets any creator or organization easily put together NFT-gated communities and experiences, whether it’s online or in the physical world. The use cases are still in the early days and many more are to come.
