How to test interactions of my contract with other contracts, like a USDT/BUSD on a hardhat local environment?
I write a smart contract, that should interact with another smart contract, such as USDT and BUSD.
I use a hardhat environment and her local environment, not a testnet.
For testing those interactions I must copy needed smart contracts locally, or I can just extend safeERC20 with name USDT and BUSD accordingly?

Create a Mock of USDT, BUSD

Or if you want, you can fork mainnet data to interact with the exact contract in the real world (locally)
