The best way to start writing smart contracts with fhEVM is to use our Hardhat template.
It allows you to start a fhEVM docker image and run your smart contract on it. Read the README for more information.
Welcome to the documentation for fhEVM Solidity Library! This comprehensive guide provides developers with detailed information on the library's functions, parameters, and usage examples. Explore how to leverage TFHE's powerful capabilities for computing over encrypted data within Solidity smart contracts, enabling secure computations and encrypted data manipulation. Unlock a new level of privacy and confidentiality in your blockchain applications with fhEVM Solidity Library.
To get started with fhEVM Solidity Library, you need to install it as a dependency in your JavaScript project. You can do this using npm (Node Package Manager) or Yarn. Open your terminal and navigate to your project's directory, then run one of the following commands:
This will download and install the fhEVM Solidity Library and its dependencies into your project.
You can use to interact with a blockchain using fhEVM. If you want to send an encrypted input, you need to encrypt it with for example. It becomes more complex if you want to reencrypt a value directly in Remix.
To avoid this problem, we developed a with these two missing features:
Encryption of input
Generation of public key and signature for reencryption and decryption.
You can use it on .
First, to import TFHE library, simply import it at the top of your contract.
import "fhevm/lib/TFHE.sol";
Be sure to be on the correct network before deploying your contract
We provide a docker image to spin up a fhEVM node for local development.
