# Elys-Network Automation Script
# This script was created to automate voting and upgrade for Elys-Network.
# It checks if the latest proposal is upgrade-related and has VOTING_PERIOD status.
# If yes, it votes for this proposal and saves its id to a file (this part is temporary till I test the API option).
# Then it scrapes the binary version from the proposal "Plan" object and builds it. (also considering to download binary using proposal info instead of building)
# Creates a related folder in .elsy/cosmovisor and copies the new binary.

This script was created to automate voting and upgrade for Elys-Network.

1. It checks if the latest proposal is upgrade-related and has VOTING_PERIOD status.
2. If "yes", it votes for this proposal and saves its "id" to file(this part is temporary till I test API option).
3. Then it scrapes the binary version from the proposal "Plan" object and builds it. (also considering to download binary using proposal info instead of building)
4. Create a related folder in .elsy/cosmovisor and copy the new binary.
