When I run my scrpt it gives me an error "No broadcast in progress to stop" when I comment out the vm.stopBroadcast() ti works... why is that?

[@vydesolaris]

if you are using methods with start prefix (vm.startPrank, vm.startBroadcast, etc), then you have to write their 'friends' aka methods with stop prefix (vm.stopPrank, vm.stopBroadcast, etc)

Did we not have to manually pass in the etherscan API key to the CLI command? What about using the other foundry commands like chisel and anvil for deploying?

[@priyanshupanda6699]

How to choose network while deploying like hardhat ? Also how to custom set constructor arguments using network provided

[@smartcontractprogrammer]

change it in your .env file

[@sayandcode]

I heard theres a better way to handle env like pvt keys in foundry now?

[@smartcontractprogrammer]

yeah there definitely is a better way, but I've never bothered

[@vydesolaris]

How can I verify contracts on other network like Arbitrum or Polygon?

[@smartcontractprogrammer]

Use the block explorer for the chain

[@neerosity]

using .env file is very bad idea in foundry... can you make a video how to use --keystore to store private key and then use that in script file set address as admin and also cli to call deploy script instead of using env variable.

[@vydesolaris]

this will be a good idea!

[@SynapseNervosa]

He has the vid he made recently where he sets up a keystore in cast wallet. Follow that tutorial to set up your wallet in cast, then instead of using the arg --private-key when deploying the script in the cli, you would use the arg --account to use your foundry keystore to deploy the contract.

@@SynapseNervosa thank you but I figured it out earlier, it's almost 5 months when I asked this🙂
