  • ZEN 5.0.0 is the official Mainnet Release
  • ZEN 4.1.1 (previous version) is going to deprecate on Mainnet at block #1502084, on February 6th, 2024 at approximately 6:00 AM UTC. Please, update to ZEN 5.0.0 before February 6th, 2024.
  • ZEN 5.0.0 will perform a network upgrade on Mainnet via Hard Fork at block #1502800, on February 7th, 2024 at approximately 12:00 PM UTC.
    • ZenIP-42207 to fully remove the shielded pool from Horizen will be implemented with this release:
      • All transactions involving shielded addresses will no longer be accepted at the consensus level once the hard fork activates
      • RPC calls z_sendmany and z_mergetoaddress have been partially disabled so that it will no longer be possible to submit transactions involving shielded addresses (transparent-to-shielded, shielded-to-shielded, and shielded-to-transparent) once the hard fork activates. Transparent-to-transparent transactions will still be accepted and submitted to the network.
  • Only nodes running on Mainnet have to be updated.


After the previously mentioned Hard Fork, it will no longer be possible to perform any transactions involving shielded addresses. It is highly recommended to move funds out of the shielded pool before then. Directly depositing funds from shielded addresses to exchange wallets is strongly discouraged.
