This Request Node acts as a relay server which helps reduce friction and costs for the end user. The user signs the request contents, but the node funds the fees required to persist the contents in the various protocol layers.
The Request Network Foundation operates several Request Nodes which builders can use to quickly test the protocol. However, for production, we advise you to run your own node which can be installed via either npm or docker.
Interaction between SDK and Request Node
Shown below is a diagram that depicts how the SDK and Node interact with the protocol.
