Make Wallet API calls


This page relates to the statechannels server wallet ONLY. It is a work in progress.

In the following diagram A and B are each a separate server application each with their own statechannels server wallet instance running in the same process.

The diagram shows a typical "happy path", directly-funded state channel interaction between those applications, their respective Wallets, and the Blockchain. The id of the channel is '0xabc', for illustrative purposes.
