#
# This script helps initializing the JoinMarket docker containers.
# Its main goal is to make CoinJoin transactions possible in the regtest environment.
#
# It has two responsibilities:
# - funding wallets in all containers with some coins
# - starting the maker service in the secondary and tertiary container
#
