// When using the hardhat network, you may choose to fork Fuji or Avalanche Mainnet
// This will allow you to debug contracts using the hardhat network while keeping the current network state
// To enable forking, turn one of these booleans on, and then run your tasks/scripts using ``--network hardhat``
// For more information go to the hardhat guide
