JSON-RPC altered semantics

Zallet implements a subset of the zcashd JSON-RPC wallet methods. While we have endeavoured to preserve semantics where possible, for some methods it was necessary to make changes in order for the methods to be usable with Zallet's wallet architecture. This page documents the semantic differences between the zcashd and Zallet wallet methods.

Changed RPC methods

z_listaccounts

Changes to response:

• New account_uuid field.

z_getnewaccount

Changes to parameters:

• New account_name required parameter.
• New seedfp optional parameter.
  • This is required if the wallet has more than one seed.

z_getaddressforaccount

Changes to parameters:

• account parameter can be a UUID.

Changes to response:

• New account_uuid field.
• account field in response is not present if the account parameter is a UUID.
• The returned address is now time-based if no transparent receiver is present and no explicit index is requested.
• Returns an error if an empty list of receiver types is provided along with a previously-generated diversifier index, and the previously-generated address did not use the default set of receiver types.

listaddresses

Changes to response:

• imported_watchonly includes addresses derived from imported Unified Viewing Keys.
• Transparent addresses for which we have BIP 44 derivation information are now listed in a new derived_transparent field (an array of objects) instead of the transparent field.

z_sendmany

Changes to parameters:

• fee must be null if set; ZIP 317 fees are always used.
• If the minconf field is omitted, the default ZIP 315 confirmation policy (3 confirmations for trusted notes, 10 confirmations for untrusted notes) is used.

Changes to response:

• New txids array field in response.
• txid field is omitted if txids has length greater than 1.

Omitted RPC methods

The following RPC methods from zcashd have intentionally not been implemented in Zallet, either due to being long-deprecated in zcashd, or because other RPC methods have been updated to replace them.
