Sign once, prove on your device
One signature derives your keys. The proof is written in your browser.
Balances live in encrypted notes only you can read, and every trade pays the private holders.
Built on open, permissionless infrastructure
On most chains anyone can read your balance and every payment you make. HIDDEN keeps them in encrypted notes only you can open.

Send 1,500 HIDDEN to a friend and see what each part of the system learns along the way.
One signature derives your keys. The proof is written in your browser.
The fee comes from your notes. Your address never pays gas.
Their viewing key opens the note. Everyone else sees ciphertext.
A fee on every HIDDEN trade, wherever it happens, buys HIDDEN for the vault. Every note's share of the vault grows with it.
Every trade pays 3%: the 1% Pons fee and a 2% creator tax, on the curve, on Uniswap v4 or through any aggregator. 2.7% comes back to private holders.
Anyone can call harvest(). It keeps the gas for private payments topped up, then buys HIDDEN with the rest for the vault.
1.0000 at launch. It rises each time fees reach the vault, with no new shares minted.
Every note · Yours included
Each note's share of the vault is worth more HIDDEN. Only private notes earn; public HIDDEN does not.
Nobody can freeze a note, and nobody stands between you and your balance.
No admin key over notes and no upgrade. A note moves only with its owner's signature, the team included.
Zero-knowledge proofs are written in your browser in seconds. Your notes and keys never leave the page.
Private payments, sales and unshields pay a flat network fee from your notes, so your address never shows up.
Your keys come from one wallet signature. Same wallet, same keys, on any device.
Every private send comes with a proof of payment you can share: who was paid and how much, nothing about you.
Anyone can harvest the fees and any ERC-4337 bundler can carry a payment. Nobody but the owner can move a note.
HIDDEN is a plain ERC-20. Wallets, the Pons curve, Uniswap v4 and aggregators handle it unchanged.
Integration notesIntegration notesProve one payment to whoever needs it, and nothing else.
Every private send comes with a proof of payment: a link that shows who was paid and how much, checked against the chain. It says nothing about you, and it cannot move the funds.
No wallet needed to check one.
Example receipt
One private payment, told by every party that touches it.
What anyone can trace, side by side.
HIDDEN is an ERC-20 that trades like any other. Shielded, it lives in the vault as an encrypted note: the amount, the sender and the recipient are hidden, and moving it takes a zero-knowledge proof instead of a public transfer.
The purchase itself is visible on-chain, like any trade. What comes after is not: buy in the app and the tokens land straight in a private note, and the payments and sales you make from it do not link back to you.
From trading fees, not from new tokens. 2.7% of every HIDDEN trade is harvested: it keeps the gas for private payments topped up and buys HIDDEN for the vault, and the network fees private payments pay go to the vault too. It depends on how much HIDDEN trades, so nothing about it is guaranteed.
No. There is no admin key over notes and no upgrade path, and a note moves only with its owner's signature, the team included. The vault has one limited role, a guardian that can pause new deposits; it cannot move, freeze or reveal anything already inside, and it can be renounced.
A browser wallet such as MetaMask, on Robinhood Chain, and some ETH to buy HIDDEN. You sign one message to create your privacy keys; the first time, one small transaction registers them so others can pay you.
Yes. Every private send has a proof of payment you can share as a link. Whoever opens it can check, against the chain, who received that one payment and how much. It reveals nothing else about you.
Your keys come from your wallet's signature, not from this site, and the vault contract is public and immutable. Private payments go through standard ERC-4337 bundlers, so no single server stands between you and your notes.
