The project requires a .env file in the root directory to run properly. The .env file should contain the following:

INFURA_WSS=wss://rinkeby.infura.io/ws/v3/xxxxxxx
ACCOUNT_ADDRESS=xxxxxxxxxx

The INFURA_WSS value is an endpoint address from infura.io, however it can be any valid address to an Ethereum network WebSocket endpoint.

The ACCOUNT_ADDRESS is the address of a Ethereum wallet, not including the "0x" prefix.

If this configuration is in place the program can be run using cargo:

cargo run
