Foundry

The fhEVM does not work with Foundry as Foundry employs its own EVM, preventing us from incorporating a mock for our precompiled contract. An ongoing discussion is exploring the possibility of incorporating a plugin system for precompiles, which could potentially pave the way for the utilization of Foundry at a later stage.

However, you could still use Foundry with the mocked version of the fhEVM, but please be aware that this approach is NOT recommended, since the mocked version is not fully equivalent to the real fhEVM node's implementation (see warning in hardhat). In order to do this, you will need to rename your TFHE.sol imports from fhevm/lib/TFHE.sol to fhevm/mocks/TFHE.sol in your solidity source files.
