#Environment variables

Hardhat Ignition supports special environment variables that affects how deployment works:

• HARDHAT_IGNITION_CONFIRM_DEPLOYMENT: if set to false, Hardhat Ignition won't prompt the user asking for confirmation when deploying to a live network. This prompt is already not shown when running against the local Hardhat network (chainId: 31337), but you might want to set this variable if writing fully automated scripts that leverage Hardhat Ignition.
• HARDHAT_IGNITION_CONFIRM_RESET: if set to false, Hardhat Ignition won't prompt the user asking for confirmation when overwriting the previous deployment via the --reset flag on Hardhat Ignition's deploy task.
