/**
   Instructions:

   This script is meant to be run as the daemon for ./rocketarb.js
   e.g. `./rocketarb.js --daemon ./allnodes.js`

   If doing a credit minipool, you need to also add ` --amount 0` to the
   command above.

   You should complete through step 17 in this guide:
   https://blog.allnodes.com/a-step-by-step-guide-for-launching-your-own-rocket-pool-minipool-on-allnodes-777c2972526e

   Then, start step 18 but don't submit the deposit transaction. Instead,
   copy the raw tx calldata and set as an environment variable (ALLNODES_DEPOSIT_CALLDATA)
   when you run the rocketarb.js script. You will also to set the PRIVATE_KEY envvar, using
   the private key you just used to register your node and stake RPL on allnodes.
