You can start Raiden with either Geth, Parity or Infura as RPC Endpoint. All you need is an Ethereum Account and the respective keystore file funded with the tokens you want to transfer.
Certain defaults for the usage of the Raiden services are set
Per default a Pathfinding Service is used by your Raiden client when a mediated transfer is initiated. The maximum amount paid for one request to the Pathfinding services is set to 0.05 RDN and 3 different paths are requested.
By default the Monitoring Services are disabled. Enabling monitoring of channels will require a default reward value of 5 RDN for successfully monitoring your channel.
