laanwj / sendalert.cpp
Last active Jul 9, 2018
Bitcoin send alert code
View sendalert.cpp
So you need to broadcast an alert...
... here's what to do:
1. Copy sendalert.cpp into your bitcoind build directory
2. Decrypt the alert keys
copy the decrypted file as alertkeys.h into the src/ directory.
3. Modify the alert parameters in sendalert.cpp
You can’t perform that action at this time.
