fhEVM is a suite of solutions that enables confidential smart contracts on the EVM using Fully Homomorphic Encryption (FHE). This document provides a high-level overview of the fhEVM suite along with onboarding guidance tailored to specific audiences.
The fhEVM Protocol provides a TFHE Solidity library for building confidential smart contracts, a fhevm.js Javascript library to enable front‐end FHE interactions, and a range of developer tools, examples, and templates to streamline the usage for developers.
