StreamVeil lets a company or DAO send salaries, grants, and vesting as a steady, real-time flow of money — not awkward monthly lump sums. And here's what makes it different: every amount stays scrambled on the public blockchain. The network still does the accounting perfectly; it simply never gets to see the numbers.
Send someone a salary on a typical public chain and the amount is right there for the whole world to read — competitors, counterparties, and curious strangers alike. They can see what you pay, work out the rate, and follow every withdrawal. For a real company or DAO, that simply isn't an option.
You decide how much to stream. Your browser scrambles that number before it ever leaves your device, so the amount is confidential from the very first moment.
StreamVeil releases the money continuously over the period you set. Every calculation runs on the scrambled numbers, so the contract keeps the books perfectly without ever seeing a figure.
The recipient can withdraw whatever has built up, whenever they like. Each person unlocks only their own numbers with a quick signature — and you can invite an auditor any time you need to.
Deposits, rates, and balances are encrypted from end to end. Outsiders see only scrambled data, never a real figure.
Money accrues every single second against the clock. Watch it tick upward live, unlocked right in your browser.
Stop the flow in a click. When you resume, the end date shifts forward so the full amount still arrives — just a little later.
Changed your mind? Cancel any time and the unsent remainder comes straight back to you, privately, down to the last unit.
Let a trusted address view a stream's figures, one stream at a time. Compliance on your terms — never automatic, never global.
Group related streams under an organization or DAO for tidy treasury records and clean payroll management.
StreamVeil makes a deliberate choice: keep the money private, but leave the schedule out in the open. That keeps the timing logic simple, cheap, and trustless — while the only things kept secret are the figures that actually matter.
For the curious (and the judges): here's what's actually doing the work.
Deposits are pulled in and payouts are sent back using the token's own confidential transfers, and StreamVeil always books the exact amount that actually moved — so the numbers stay correct to the unit, and nobody is ever overpaid.
Pay contributors a steady salary that arrives in real time — without publishing what everyone earns.
Release funding gradually, without broadcasting the size of every award to your rivals.
Vest team and investor allocations privately, with the option to cancel and refund.
Stream invoices by the second, and pause the moment the work pauses.
Through a breakthrough called Fully Homomorphic Encryption (FHE), provided by Zama's fhEVM. It lets the network do maths directly on scrambled numbers. StreamVeil works out rates and balances on the encrypted values; the answer stays encrypted, and only the right person can unscramble it — on their own device.
Only the people on its private guest list: the sender, the recipient, and an auditor if the sender chooses to add one. To everyone else, the amounts are just unreadable data.
The addresses involved, the schedule (start, stop, and pause times), the stream's status, and the organization's name. We hide the salary, not the payday — which keeps the timing logic cheap and trustless.
It runs on the Sepolia test network, where Zama's encryption infrastructure lives. There's a built-in faucet that hands you free test tokens, so you can try everything end to end without spending any real money.
Yes. The asset you stream is an OpenZeppelin ERC-7984 confidential token, so its balances and transfers are encrypted too — not just StreamVeil's own internal bookkeeping.
Open a confidential stream in under a minute. Free test tokens are built right in — no real funds needed.
