Private payments for Robinhood Chain
A quieter way to pay.
Veilport is a private wallet for Robinhood Chain. Shield ETH, pay anyone without publishing who paid or how much, and withdraw to any address. The zero-knowledge proof is made on your own device.
Unaudited beta. Pool deposits are capped while Veilport is new.
How it works
-
1
Shield
Deposit ETH from any EVM wallet into the Veilport pool. The deposit is public; what happens next is not. Your funds become a private note only your recovery phrase can spend.
-
2
Pay privately
Send to a Veilport receive address. Inside the pool, the chain sees that a valid payment happened, never the amount or who holds the notes. Your browser builds the Groth16 proof; keys never leave your device.
-
3
Withdraw anywhere
Move funds to any public address. The relayer pays gas so the new address needs no ETH of its own, or submit directly from your own wallet. Nobody can block a direct withdrawal.
What stays private, and what does not
Privacy tools that overstate what they hide put people at risk. Here is the exact boundary.
| On-chain observers | Can they see it? |
|---|---|
| Amount of a payment inside the pool | Hidden |
| Who paid whom inside the pool | Hidden |
| Which deposit funded a withdrawal | Hidden by the proof |
| Your balance | Hidden |
| Deposits: address, amount, time | Public |
| Withdrawals: recipient, amount, time | Public |
| Relay fee amount and asset | Public |
| VPORT trading on PONS | Public |
A new pool has a small crowd to hide in. Withdrawing the exact amount you deposited, right after depositing, links the two by timing. Wait, and vary amounts.
VPORT
VPORT is Veilport's token, launched on PONS V2 on Robinhood Chain.
- Pay relay fees for less. Paying the relayer in VPORT costs half the ETH-equivalent fee, and the payment proof and fee proof settle atomically.
- Hold it privately. VPORT gets its own shielded pool: private transfers and withdrawals like ETH.
- Fair launch. 1,000,000,000 supply entirely on the PONS bonding curve. No team allocation, no presale, no developer opening buy.
- 1% creator fee on PONS trades funds relayer gas and development. PONS's own fees are separate. Buybacks are off.

Built so you do not have to trust us
No one can take your funds
The pool contracts have no owner, no upgrade path and no pause on withdrawals. The only role, the deposit guardian, can change how much new ETH the pool accepts. It can never touch notes already inside.
Withdraw even if this site is gone
The app ships its proving files and contract list with every copy. Restore your 24-word phrase, rescan straight from a public RPC, and submit a withdrawal from your own wallet.
A public trusted setup
Proof parameters come from the PSE Perpetual Powers of Tau (80 public contributions) plus a Veilport contribution sealed with the hash of a Robinhood Chain block chosen before it existed. Transcript.
Questions
Is my Robinhood or MetaMask wallet my Veilport wallet?
No. Veilport creates a separate 24-word recovery phrase for your private balance. Your EVM wallet funds deposits and can submit withdrawals, but it cannot recover shielded funds. Write the phrase down.
What does it cost?
Shielding costs normal network gas. Relayed payments and withdrawals charge a network reimbursement plus a small service fee, both shown before you sign. Paying in VPORT halves the total. Direct withdrawals from your own wallet have no Veilport fee.
Does Veilport screen addresses?
The Veilport app declines deposits from, and the relayer declines withdrawals to, addresses on the U.S. Treasury OFAC sanctions list. Neither can see hidden payments, and the contracts themselves stay open for direct use.
What happens if the relayer or this website goes down?
Your funds stay in the contracts. Restore your phrase in any copy of the app, rescan from a public RPC, and withdraw directly. Your wallet pays the gas and its address is visible as the sender.
Why is there a deposit limit?
An unaudited system should not hold more than people can afford to lose. The limit rises as the code earns trust. Private transfers and withdrawals are never limited.
Is the code open?
Yes. Circuits, contracts, the wallet and the relayer are open source, derived from Nethermind's MIT-licensed shielded pool research code with Veilport's hardening on top.
