Component

Forge

Describe the feature you would like

To have a feature where we can access in our foundry scripts the private keys input from --interactives mode or the resolved public addresses of those private keys. This way, we don't have to repeat the sender address in the --sender because we can decide which private keys to use as the sender and pass the intended address as the sender in vm.startBroadcast(sender).

For example:

uint256[] privateKeys = vm.interactives();
// Or, an optional index parameter to get from the list of input private keys
// uint256 privateKey = vm.interactives(0);   // gets the first private key entered from interactive mode

address sender = vm.addr(privateKeys[0]);

vm.startBroadcast(sender);
// ...
vm.stopBroadcast();

Additional context

Currently, when forge is run with --interactives, it doesn't seem like there is a way to access the private keys or the public addresses of those private keys provided through the interactive input in the foundry scripts. The only way (as far as I have tried) to run the foundry scripts with --interactives is:

• Provide the address of the private key through --sender on top of --interactives
• AND only use vm.startBroadcast(). I cannot use vm.startBroadcast(sender) since I cannot access the private key supplied through the interactive input and so I won't know the sender address.

Supplying the public address through --sender feels repeated because the address should already be resolvable from the private key.

Moreover, the --interactives parameter can accept more than one private keys which seems to suggest a script should be able to select one of the keys supplied to be the actual sender.

If there is a feature where we can access the input private keys or their translated public addresses in our foundry scripts, we wouldn't have to repeat the address in the --sender because our foundry script can decide which private key to use as sender and pass the correct address as the sender in vm.startBroadcast(sender).
