Hi @Nadim,
OpenZeppelin Network.js is deprecated. See: Doubling down on security
You could look at: https://github.com/NoahZinsmeister/web3-react
Alternatively (_from: https://forum.openzeppelin.com/t/doubling-down-on-security/2712_)
The full code of network-js is not very long and it’s easy to follow, making it easy to replicate the logic in your own app if needed.
Otherwise you can use https://github.com/PaulRBerg/create-eth-app.
