This small express server acts as faucet. Users can request Ether by sending a request and if they have not more Ether then a threshold value, they are being send a small amount of Ether.
The account to be used for sending Ether from, must be specified in config.json:
{
"MNEMONIC": "",
"INFURA_API_KEY": "",
"PRIVATE_KEY_OF_FAUCET_ACCOUNT": ""
}The Infura API key can be obtained by creating a project on infura.io: it is the Project ID under View Project.
