Remix
You can use Remix to interact with a blockchain using fhEVM. If you want to send an encrypted input, you need to encrypt it with fhevmjs CLI tool for example. It becomes more complex if you want to reencrypt a value directly in Remix.
To avoid this problem, we developed a version of Remix IDE with these two missing features:
Encryption of input
Generation of public key and signature for reencryption and decryption.
You can use it on https://remix.zama.ai.
Usage
First, read the usage section regarding Solidity version and EVM.
To import TFHE library, simply import it at the top of your contract.
import "fhevm/lib/TFHE.sol";
UPDATE: Remix doesn't take into consideration the package.json of fhevm to fetch dependencies. If you're using fhevm/abstracts/EIP712WithModifier.sol, it will fetch the latest version of the @openzeppelin/contracts package, which runs only on the Shanghai EVM (Solidity version ^0.8.20). Since fhEVM is not compatible with versions above 0.8.19, it will fail. To fix that, go to .deps/fhevm/abstracts/EIP712WithModifier.sol and change the imports as follows:
Be sure to be on the correct network before deploying your contract
