cofhejs is a TypeScript library that enables seamless interaction with FHE-enabled smart contracts via the CoFHE service. CoFHE is a privacy-preserving computation service for EVM-compatible networks, currently supporting Ethereum Sepolia and Arbitrum Sepolia. The library handles encryption, decryption, and permit management, allowing dApps to keep user data private while leveraging fully homomorphic encryption on-chain.
- Encrypt input data before sending to smart contracts.
- Create and manage permits for secure access and decryption.
- Unseal and decrypt contract outputs for user display.
For more details, see the cofhejs documentation.
