// QuickNode endpoints consist of two crucial components: the endpoint name and the corresponding token
// For eg: QN Endpoint: https://docs-demo.tron-mainnet.quiknode.pro/abcde123456789
// endpoint will be: docs-demo.tron-mainnet.quiknode.pro:50051  {50051 is the port number for Tron gRPC}
// token will be : abcde123456789
