Their core product, CoFHE, is an FHE Coprocessor that enables confidential smart contracts and encrypted computation directly on encrypted data without trusted hardware. This allows developers to integrate privacy into existing EVM-compatible blockchains with standard tools like Solidity, serving DeFi applications, asset tokenization, and AI models.
