The rpc command

Available on crate feature rpc-cli only.

zallet rpc lets you communicate with a Zallet wallet's JSON-RPC interface from a command-line shell.

• zallet rpc help will print a list of all JSON-RPC methods supported by Zallet.
• zallet rpc help <method> will print out a description of <method>.
• zallet rpc <method> will call that JSON-RPC method. Parameters can be provided via additional CLI arguments (zallet rpc <method> <param>).

Comparison to zcash-cli

The zcashd full node came bundled with a zcash-cli binary, which served an equivalent purpose to zallet rpc. There are some differences between the two, which we summarise below:

For parameter parsing, zallet rpc is (as of the alpha releases) both more and less flexible than zcash-cli:

• It is more flexible because zcash-cli implements type-checking on method parameters, which means that it cannot be used with Zallet JSON-RPC methods where the parameters have changed. zallet rpc currently lacks this, which means that:

  • zallet rpc will work against both zcashd and zallet processes, which can be useful during the migration phase.
  • As the alpha and beta phases of Zallet progress, we can easily make changes to RPC methods as necessary.

• It is less flexible because parameters need to be valid JSON:

  • Strings need to be quoted in order to parse as JSON strings.
  • Parameters that contain strings need to be externally quoted.
