A send moves value from your notes to someone else's, inside the pool. The chain records that a transfer happened — not from whom, to whom, or how much.
Steps
- Open the Send tab.
- Enter an amount. Max shows the most a single transfer can move (why there is a limit).
- Paste the recipient into To:
- a shielded address — starts with
zks; - or any Solana address.
- a shielded address — starts with
- Press Send.
The activity panel walks through four steps: Building the proof, Waiting for your signature, Sending, Confirming. The proof takes a few seconds. The first send also downloads the transfer proving key, about 16 MB, which your browser then keeps.
Sending to a shielded address
Nothing more to do. The note is encrypted to the recipient's key; their wallet finds it on its next sync and it appears in their balance.
Ask the recipient for their address from the Shielded address row of their balance panel.
Sending to a Solana address
You can pay an address that has never heard of zkSVM — it does not need to exist yet, or hold any SOL. Two things are different:
You choose when it comes back. Under Comes back if unclaimed after, pick 1, 7 or 30 days, or Never. If the recipient has not collected by then, you can take the payment back. See Payments that come back.
You pass on a claim code. After sending, the activity panel shows a code
beginning with zkclaim. Press Copy claim code and send it to the
recipient, over any channel you like.
What the chain records
| Public | Hidden |
|---|---|
| That a transfer happened | The sender |
| The wallet that paid the network fee | The recipient |
| The amount |
The fee payer is visible on every Solana transaction, and when you send from the app that is your wallet. It shows that your address used the pool at that moment — not what it did there.
The two-note limit
One transfer spends at most two notes. If the amount you want to send is spread over three or more, the app tells you so. Merge first: send your balance to your own shielded address, which combines two notes into one, and repeat if needed. Notes and balance has the details.
Cost
The network fee, plus rent of about 0.00095 SOL for each note spent — the permanent record that makes double-spending impossible. A transfer uses about 172,000 compute units.
