ERC7984ERC20WrapperMock - Fhevm

This example demonstrates how to wrap between the ERC20 token into a ERC7984 token using OpenZeppelin's smart contract library powered by ZAMA's FHEVM.

{% hint style="info" %} To run this example correctly, make sure the files are placed in the following directories:

.sol file → <your-project-root-dir>/contracts/
.ts file → <your-project-root-dir>/test/

This ensures Hardhat can compile and test your contracts as expected. {% endhint %}
