# democlip on https://www.youtube.com/watch?v=e_V9V7n2p_I

# depends on:
#  - pycoin (with small patch for DOGE : https://github.com/richardkiss/pycoin/issues/332)
#  - jq
#  - qrencode
#  - wget
#  - bc

# does not depend on:
#  - own running coin daemon

# key.sh just contains key=dgpv5xxxxxxx from a walletdump, you could also put key=dgpv5xxxxx in this script
. ./key.sh

# to get all 1000 keys into a dogecoin 1.14, set keypool=1000 in dogecoin.conf and do the rpc call keypoolrefill
