Inco is a confidentiality layer designed to extend privacy to public blockchains by enabling confidential smart contracts without modifying existing chains. Developers can use its fhEVM—an EVM-compatible environment powered by Fully Homomorphic Encryption (FHE), Trusted Execution Environments (TEEs), and Multi‑Party Computation (MPC)—to operate on encrypted inputs such as euint256, ebool, and eaddress while preserving composability with other EVM-based protocols. Its architecture includes smart contract libraries, Confidential Compute Nodes, and Decryption Nodes to manage encrypted workflows and callback relays securely. By abstracting cryptographic complexity behind standard Solidity interfaces, Inco allows developers to integrate privacy-preserving operations seamlessly into familiar stacks like Remix, Hardhat, or MetaMask.
