# This script will auto claim BP rewards
#
# The premise is based on a safe "claim" only account permission
#
# Please refer to https://github.com/BlockMatrixNetwork/eos-bp-failover/tree/master/claim-rewards
# for more info on how to set this up
#
# Example call:

# ./claim_rewards.sh PW5JfDojLFSmMTJfDLwQE5zvE4mjSBDwUpfuZWmws5Ecm4AF2StjW

# Update SLACK_WEBHOOK if you want to be notified via an incoming webhook
