A payment.
Without the
open book.
A public transfer tells a story about your wallet. A shielded payment proves that the transfer is valid while keeping its note owners and value private.
Inside Zynull, a proof replaces public payment details. Deposits and withdrawals still have public addresses and amounts.

Is Zynull a wallet or a protocol?+
Zynull is a privacy protocol on Solana. The app is an interface to that protocol: it creates a private account, encrypts recovery data and generates proofs in your browser.
What can other people see?+
Internal note owners, assets and payment amounts are protected by the shielded protocol. Deposits and withdrawals expose public accounts and amounts. Timing, relayer activity and network metadata can also reveal information.
Can I send directly from Phantom?+
Connect Phantom in the Zynull app to approve a public deposit. Send privately and withdraw from your separate Zynull account. A Zynull private address cannot be pasted into Phantom’s standard Send field.
Can I try it with real SOL?+
The test release supports Solana devnet and an isolated local ledger with test SOL and TEST tokens. It is a development alpha with a test setup and no independent audit. It is not a mainnet release.
How does recovery work?+
Export the encrypted backup from your private account and keep its password separately. A recovery file and the correct password restore access. Create a fresh backup after adding a private address. The service cannot recover a forgotten password.
