You can test NU7 without risking real ZEC by using Zcash’s public testnet and checking that your wallet or node is on the test network before you create addresses or send funds. NU7 activated on public Testnet on October 4, 2026, at height 4,465,026, according to the Zcash Foundation’s October 6 update. Testnet coins are not actual ZEC and have no monetary value.
How do I test NU7 without real ZEC?
- Select public testnet. In the Zcash CLI,
-testnetselects the test chain. Before generating an address or sending anything, confirm that the wallet or node itself reports testnet. The CLI manual lists testnet RPC port18232; keep testnet and mainnet configuration and data clearly separated. Zcash CLI manual. - Use NU7-capable software for consensus testing. Zebra
7.0.0-rc.0was announced as a release candidate supporting NU7 on public Testnet, with testnet operators encouraged to run it. It is a release candidate, not a stable release. Check the relevant release notes before installing or upgrading: Zcash Foundation: Zebra 7.0.0-rc.0. - For wallet-only experiments, use the documented developer-tool walkthrough. The zcash-devtool documentation walks through initializing a testnet wallet, syncing it against a testnet light-wallet service, receiving test funds, and checking a balance. Treat its commands and service details as version-sensitive.
- Keep test value separate from real value. Testnet coins cannot be redeemed as ZEC. Never send mainnet funds to a testnet address, and do not assume funds or addresses transfer between networks. The Zcash Android Wallet SDK documentation states that testnet coins are distinct from actual ZEC and have no value.
The official materials cited here establish the network selection, the NU7-capable testnet release candidate, and a wallet workflow, but they do not establish one fully verified, current sequence for installing Zebra and creating and confirming a post-activation NU7 transaction. Check the matching release documentation for exact commands rather than treating examples as tested instructions.

The October 2 Zebra announcement also said no Mainnet activation height had been set at that time and identified 7.0.0-rc.0 as a release candidate, not a stable release. That was a statement about the situation on October 2, not a current Mainnet schedule: Zebra 7.0.0-rc.0 announcement.
Public testnet or regtest: which should I use?
| Environment | Network exposure | Block production | Best fit | CLI selection |
|---|---|---|---|---|
| Public testnet | Shared public test chain | Live chain behavior | Testing NU7 on the public network | -testnet |
| Regtest | Special regression-test chain | Blocks can be solved instantly | Repeatable regression tests and application development | -regtest |
These modes are not interchangeable. Regtest is useful for controlled, quick development cycles, but it does not show how software behaves on the shared public testnet or demonstrate public-testnet NU7 activation. The Zcash CLI manual documents both options: Zcash CLI manual.
