zcashd will reach its end-of-life service halt on July 18, as scheduled, completing the Zcash ecosystem's migration to Rust-based, next-generation Zcash client software. zcashd will not support NU6.3 (Ironwood).
Node operators will need to complete their transition to Zebra and the ZODL-maintained Zallet wallet prior July 18. Only Zebra nodes will be on the peer-to-peer network from that time onward.
We've successfully worked with and continue to assist partners in their migrations to bring the ecosystem forward. Zcash is upgrading.
