# Fetches the collateral from the ARTIS ValidatorSet contract (pre POSDAO).
# Will succeed only if the validator was first removed through a governance vote (https://voting.artis.network)

# The script assumes a node with unlocked and funded account (the one for which collateral is deposited) to be running on localhost, with http RPC available on port 8545.
# It will create and send the transaction, print the transaction hash and then exit.
