you'll need to put a config.json
file under src
folder, the content should look like this:
{
"name": "Test",
"pk": "0xaaaaaa............", // private key
"url": "http://warringstakes.meter.io:8669", // full node API url
"alice": "0x1f9983a259f023f733978582259267c1f17303ce", // test recipient address #1
"bob": "0xf30320537817d49ddb4f3f6878296e046de0a6fe" // test recipient address #2
}
