Adding --dry-run & --quiet Arguments for Testing Vanity Safe Addresses

[dysbulic]

This PR adds support for two new arguments to the safe-creator command: --dry-run and --quiet.

--dry-run will cause the system to stop after the projected Safe address is generated. It also prevents the system from prompting before doing the generation.

--quiet limits the amount of information output to the console to prompts, errors, and the address of the generated Safe. If used in conjunction with --dry-run, only the projected Safe address will be output, making it suitable for easy scripting.

@dysbulic I like your idea. I guess this runs inside of a script. So I think the solution should be to edit the code to allow vanity addresses, right?

Could you share the script you are using with your code?

while [[ $COUNT -gt 0 ]]; do
  SALT=$(cat /dev/urandom | tr -dc 0-9 | head -c${2:-25})
  ADDR=$(docker run -it safe-cli:testing safe-creator --threshold 2 --owners ${OWNERS[@]} --salt-nonce $SALT --dry-run --quiet https://mainnet.optimism.io $KEY)
  echo "$(printf '%4d' $COUNT): $SALT: $ADDR"
  COUNT=$((COUNT - 1))
done

It's pretty slow, but it illustrates the procedure. (Also, I renamed --only-generate to --dry-run to be in line with other programs.)
