I'm trying to create a Farming smart-contract. I'm completely new to solidity so i want to know if there's a way i can import an existing token from the blockchain, then call methods on that token's contract from my farm.
In tutorials I've seen, i see them create a "Fake token" then import it from same directory. My curiosity is; what if the token i want the users to deposit is already deployed to the network, how do i import that token so i can be able to call methods like transfer/transfer from on it.
