Wallet RPC Guide
​
This is a list of the RPC calls, their inputs and outputs, and examples of each. This list is autogenerated and was last generated on: 2019-04-08
Many RPC calls use the JSON RPC interface while others use their own interfaces, as demonstrated below.
Note: "atomic units" refer to the smallest fraction of 1 BELDEX which is 1e9 atomic units.
