Notable changes

zcashd is being deprecated in 2025. Full nodes are being migrated to zebrad, and the Zallet wallet is being built as a replacement for the zcashd wallet.

For some of zcashd's JSON-RPC methods, zebrad or Zallet should be a drop-in replacement. Other JSON-RPC methods may require modified usage, and some JSON-RPC methods will not be supported.

You can find all information about the zcashd deprecation process on this webpage, which you can monitor for future updates: https://z.cash/support/zcashd-deprecation/

We are collecting information about how zcashd users are currently using the existing JSON-RPC methods. The above webpage has a link to a spreadsheet containing the information we have collected so far, and the planned status for each JSON-RPC method based on that information. If you have not provided feedback to us about how you are using the zcashd JSON-RPC interface, please do so as soon as possible.

To confirm that you are aware that zcashd is being deprecated and that you will need to migrate to zebrad and/or Zallet in 2025, add the following option to your config file:

Platform Support

• Ubuntu 20.04 LTS has been removed from the list of supported platforms. It will reach End of Support on May 31st 2025, but it no longer satisfies our Tier 2 policy requirements because GitHub no longer supports Ubuntu 20.04 runners.

RPC Changes

• The RPC methods keypoolrefill, settxfee, createrawtransaction, fundrawtransaction, and signrawtransaction have been deprecated, but are still enabled by default.
• The RPC methods z_getbalance (which was previously deprecated), and getnetworkhashps, and the features deprecationinfo_deprecationheight and gbt_oldhashes, have been disabled by default. The addrtype feature is now disabled by default even when zcashd is compiled without the ENABLE_WALLET flag.
