Panther is a cross-protocol layer that uses zero-knowledge technology to build DeFi solutions that meet regulatory requirements and satisfy users' on-chain data privacy needs. The goal of Panther is to allow seamless access to DeFi and create a cross-chain-supported architecture that serves different use cases. Panther's zero-knowledge primitives are also generalizable to KYC, selective disclosures between trusted parties, private ID, voting, and data verification services. Starting July 10th, Panther's Testnet will be available for voluntary testers.
