PHCR

PhotoChromic introduces a unique use case for non-fungible tokens (“NFTs”) by integrating them with user identity, to develop a biomimetically managed model of Self-Sovereign Identity (“SSI”) on the Blockchain. Using NFTs, PhotoChromic aims to make identity programmable, verifiable, universally addressable, and digitally secured.

Powered by an ERC-20 token, $PHCR, running on the Ethereum blockchain, PhotoChromic addresses the current challenges faced by people the world over, as they pursue ownership over, and the ability to secure, their identity. PhotoChromic gives control and ownership of user identity back to the individual, where it belongs.
