# Instructions
|
|
#
|
|
# Testing mode:
|
|
#
|
|
# 1) From the MMGen repository root, start the mainnet test suite daemons as follows
|
|
# (note that Geth is the default testing daemon for ETH):
|
|
#
|
|
# test/start-coin-daemons.py btc ltc eth
|
|
#
|
|
# 2) Then run the script as follows:
|
|
#
|
|
# PYTHONPATH=. MMGEN_TEST_SUITE=1 examples/coin-daemon-info.py btc ltc eth
|
|
#
|
|
# Live mode:
|
|
#
|
|
# 1) Start up one or more of bitcoind, litecoind or geth with the standard mainnet ports
|
|
# and datadirs. For geth, the options ‘--http --http.api=eth,web3’ are required.
|
|
#
|
|
# 2) Then run the script as follows:
|
|
#
|
|
# PYTHONPATH=. examples/coin-daemon-info.py btc ltc eth
