Deep Dive
1. Zcashd Deprecation Plan (August 2025)
Overview: The Electric Coin Company announced the phase-out of the legacy zcashd
node software, with full migration to Zebrad (Rust-based node) and Zallet (new wallet) by 2025.
Key changes include:
- Discontinuation of 12+ RPC methods (e.g., keypoolrefill
, signrawtransaction
).
- Ubuntu 20.04 support dropped due to GitHub CI limitations.
- Users must explicitly confirm awareness via config file (i-am-aware...=1
).
What this means: This is neutral for ZEC as it modernizes infrastructure but requires node operators to adapt. Long-term, it aims to improve scalability and developer experience. (Source)
2. Zashi CrossPay Upgrade (16 September 2025)
Overview: The Zashi wallet integrated Near Protocol’s “Intents” system, enabling shielded ZEC to perform cross-chain swaps across 20+ blockchains without exposing metadata.
Technical highlights:
- Uses zero-knowledge proofs to validate transactions off-chain.
- Supports encrypted memos and privacy-first architecture.
What this means: This is bullish for ZEC because it expands real-world utility for private payments in DeFi and bridges Zcash’s privacy with broader ecosystems. Shielded transaction volume spiked 18% post-launch. (Source)
3. NU6.1 Testnet Activation (April 2025)
Overview: Network Upgrade 6.1 deployed on testnet, introducing:
- Enhanced Orchard pool logic for shielded transactions.
- Fixed transparent balance calculation bugs affecting RPC methods like getbalance
.
What this means: This is neutral-to-bullish, as it strengthens ZEC’s privacy guarantees but requires mainnet validation. Developers can test NU6.1 via -nuparams=4dec4df0:HEIGHT
. (Source)
Conclusion
Zcash’s 2025 updates prioritize privacy interoperability (CrossPay) and infrastructure modernization (Zebrad migration). With shielded transactions now usable cross-chain and node software evolving, will ZEC’s developer activity sustain its 90-day 89% price rally?
