A private route for Robinhood Chain

Leave as one wallet.Come back as another.

A private route for Robinhood Chain. Funds cross Zcash's shielded pool and arrive in a fresh wallet.

Private by proof, not by promise.

The mark is the route: one wallet, the pool, another wallet. Nothing joins the two.

Route live

The route and the public tools are live. The token is not issued. Numbers marked live are read from the chain as you look.

Community project. Not affiliated with, endorsed by or sponsored by Robinhood, the developers or foundations behind Zcash, or NEAR.

Token

$STYNX

Not issued

$STYNX has no contract yet.

The crossing ships first, the token after it. When the contract exists it will be printed here before anywhere else.

Any other address using this name is not Stynx. Check it against this page.

Glass box

Every wallet is a glass box.

A fresh wallet has to be funded by something. Fund it from your main wallet and the two are tied together in public, permanently.

Funded by: Explorers print it on every address. Wallet watchers and copy-traders follow that trail in minutes.
An exchange hop: Trades the public tie for an account record and a withdrawal pattern.
A bridge: Carries the tie across chains. It does not cut it.
A new shielded pool: Opens empty. One depositor is not a crowd, and exits only return to the wallet that deposited.

Sample trail

0x91c4…e07ayour new wallet, first transaction 14 days ago

0x7a3f…9c21your main wallet, two years of history

One hop. Anyone who knows one wallet now knows both.

Crossing

What happens to one crossing

Scroll to follow $1,000 from wallet A to the Ghost.

01 / 06 · Quote

Pick an amount and a wait.

The wallet you leave from is checked against the public sanctions list. The full cost and the crowd for that size are shown before anything moves.

Which exit was yours? That is the point.

Crowd

Count the crowd before you pay.

Privacy is a crowd, and a crowd takes years to gather. Stynx does not build a pool. It uses the one Zcash already has, and shows you how many exits look like yours.

Size of one exit piece

How long you wait

similar exits within 10% of $1,000 in 3 days

Crowd gradeFair

Fair. A longer wait makes it deep.

This is the crowd on the Zcash side, and an upper bound: somebody who also watches the swap rail pay out on Robinhood Chain sees a smaller one. See the two layers below.

Each dot is one exit from Zcash's shielded pool in that window, placed by size. The lit ones are within 10% of yours. 3,591 exits in 3 days.

Measured from the public chain on 2 October 2026. Measured sample. The live meter ships with the public tools.

1,100

exits in one day

487

entries in one day

8,669

exits in seven days

752

fully shielded moves in one day

About 4.9M ZEC sits shielded, 29% of supply. Measured from the public chain on 2 October 2026.

Two layers

The crowd has two layers. Only one can be counted today.

Layer 1 · on Zcash

Borrowed. There on day one.

Somebody who reads only the Zcash chain has to match one entry to one of about 1,100 exits a day. For most sizes that means tens to hundreds of look-alikes inside a few days.

Layer 2 · on Robinhood Chain

Has to be built.

The Ghost is visibly funded from a ZEC swap. A determined observer can narrow the search to wallets funded that way, and at launch that group is small.

Arrivals from ZEC, last 7 days: not counted yet; Telling these arrivals apart needs the swap rail's own index, which is not open to the meter yet. Until it is, the grade above is layer 1 only.

What makes layer 2 deeper

01Every crossing adds one arrival.
02Zcash holders entering Robinhood Chain through the same exit look identical to the last leg of a crossing. Their door is free for that reason.
03Later: an exit that passes through a second chain.

A product that shows the larger number and does not say what it leaves out is selling a promise.

Habits

A pool is only as private as the habits around it.

Peer-reviewed analysis of Zcash (Kappos et al., USENIX Security 2018) showed that simple usage patterns shrink the crowd considerably. Stynx makes the opposite habits the default.

Wait
How a crossing gets readIn and out within the hour.
What the planner does72 hours by default. Leaving earlier is yours to choose, and the app says what it costs.
Split
How a crossing gets readOne exit, one size.
What the planner doesAbove $500 a single exit of everything is refused. The plan cuts two or three uneven pieces.
Reshape
How a crossing gets readThe same amount leaves that came in.
What the planner doesA piece within 3% of the entry is refused above $500, and flagged below it.
Stagger
How a crossing gets readEvery piece leaves at once.
What the planner doesThe plan spaces the pieces 40 minutes to 3 hours apart. You release each one.
Remainder
How a crossing gets readOne wallet receives the full amount, and its total gives it away.
What the planner doesPart stays shielded for another wallet. The planner warns before a full exit.
Fresh
How a crossing gets readExiting to a wallet that already has history.
What the planner doesThe app makes a new wallet for the far side. A wallet you paste can be checked for history when you ask, through your own wallet.

Limits: $50 minimum, $10,000 maximum per crossing.

Line of sight

Who can see what.

Four parties touch a crossing. None of them is handed both ends.

The public

any explorer

Wallet A swapped an amount into ZEC
The Ghost was funded from a ZEC swap
Both amounts, both times

The other: each release
The IP address that uses them

Amounts or notes inside the pool

What nobody above is handed, they can still guess at from amounts and timing, which is what the wait and the uneven pieces are for. And Stynx cannot hide an IP address: leave from another network than you entered on if yours matters to you.

A new trail starts here

Ghost

The Ghost: a wallet with no past.

An unused address on Robinhood Chain. The first piece carries ETH for network fees, so it can transact the moment it exists.

Exit plan

0.7216 ZEC shielded

Ghost 0x91c4…e07a · unused · 0 transactions

Piece	Size	Asset	Leaves
1	0.2310 ZEC	ETH	now
2	0.3067 ZEC	USDG	in 2h 40m
rest	0.1839 ZEC	stays shielded

No piece equals your entry.
This Ghost does not receive the full amount.
You release each piece yourself, when you choose.

[ Sample exit plan ]

Second door

Already hold ZEC?

Send from the shielded balance of any Zcash wallet and receive ETH or USDG on Robinhood Chain in about 7.5 minutes. No toll. It is the same exit a crossing uses, and every arrival of this kind is cover for everyone else.

Toll

One toll, on the way in.

The way out is free, and no Stynx server is told where it goes.

Toll

paid once, at entry

Class	Hold in wallet A	Toll
Visitor	0	0.30%
Drifter	1M	0.24%
Phantom	5M	0.18%
Wraith	10M	0.12%
Exit		Free
Second door (ZEC holders)		Free

What one crossing costs

Amount

Between $50 and $10,000 per crossing.

Class

Toll: 0.30%; $3.00
Swap in and out est.: 0.57%; $5.70
Zcash network fees est.: $0.40
Total: 0.91%; $9.10
Arrives, before ZEC price movement: $990.90

Swap cost is an estimate from three live quotes taken on 2 October 2026. The app shows a live quote before you pay.

Not on the receipt: ZEC moves while you wait. That can cost or return more than every fee above.

Why at entry only

01The source wallet is public anyway, so a toll there reveals nothing new.
02Revenue arrives in Robinhood Chain assets, ready for the buyback.
03The exit stays a plain swap with no Stynx tag on it. That is what lets it sit among other arrivals.

Where a toll goes

The 0.30% is everything the swap rail takes on the way in, its own share included. What reaches Stynx is 0.10% today and 0.15% once Stynx holds a partner key with the rail. The user pays exactly the number on the screen either way.

Buyback and burn of $STYNX50%
every burn published
Operations30%
light nodes, indexer, infrastructure
Security reserve20%
reviews, bounties

$1M routed in a month nets $1,000 to $1,500. At launch volumes the toll does not fund a team, and this page does not pretend otherwise.

Papers

Private by default. Provable on request.

When an exchange or a counterparty asks where the funds came from, you can show them, and only them.

1
They ask
An exchange or a counterparty asks the Ghost's owner for the source of funds.
2
You create Papers
The browser bundles the entry transaction, the shield, each release with the arrival it paid for, and a Zcash viewing key limited to this crossing.
3
They check
The recipient verifies the bundle against the public chains.
4
Nobody else learns
Nothing is published. Without your action nobody can produce these Papers, Stynx included.

Pass

$STYNX is a pass. It lowers the toll and never buys privacy.

Waits, split rules, limits and the crowd are identical for every user. A tool that sells a deeper crowd to some users makes the crowd shallower for all of them.

What it does

Lowers the toll, by class, read from the source wallet at quote time.
Unlocks deeper Glass Box traces and more checks a day.
Opens exposure watch: an alert when a new public tie appears on your addresses.
Is bought back and burned with half of every net toll.

What it may never do

Buy a longer wait, a better split or a deeper crowd.
Be required in the Ghost. A check on the destination would tag it.
Be staked or locked for a reward. There is no emission.

Contract facts

Supply: 1,000,000,000 $STYNX, fixed
Team allocation: 0. Fair launch, all of it to the curve
Chain: Robinhood Chain (EVM 4663)
Launch: Launchpad bonding curve to DEX graduation, LP locked
Rule: Product live before token
Status: Not issued

The first 72 hours

Hour 0: Token live. The fee wallet address is published.
Daily: Creator fees claimed, $STYNX bought and burned, transaction links on the burn page.
Hour 72: Closing report: fees received, tokens burned, share of supply removed.
Afterwards: 50% buyback and burn, 50% development, reported every week.

In this phase the team executes burns from the published wallet. A later phase moves the split into a contract with no owner. Until then the burn page is the proof.

$STYNX burned

Nothing to burn yet. The token is not issued.

Workings

Everything private runs in your browser.

Stynx deploys nothing that holds or routes user funds. There is no pool contract, no router contract and no exit endpoint.

Keys and recovery

Each crossing gets its own key, made in the browser: 24 words, a standard Zcash wallet phrase. Nothing is paid before you confirm you wrote them down.
With the words the crossing restores in the app on any device. They are a standard Zcash phrase, so a Zcash wallet that supports the pool the funds sit in can open them without Stynx.
The key is kept in this browser's storage and nowhere else, unencrypted. Clearing the browser without the words loses the funds, and anyone who can open the unlocked browser can read it.
One key per crossing, so a viewing key exported for Papers shows that crossing only.

On-chain footprint

Robinhood Chain: One plain transfer in from wallet A, plain transfers out to the Ghost, $STYNX balance reads, burns.
Zcash: One transparent receipt, one shielding transaction, one shielded spend per exit piece.
Not deployed: No pool, no router, no relayer.

Fail-safes

If the rail does not confirm the exact toll and recipient, the quote is rejected.
An entry that cannot complete is refunded to wallet A. An exit that cannot complete returns to a Zcash address your browser controls, one kept for that exit wallet alone.
Every transaction is built, written down, and only then sent. A closed tab sends the same one again; it never builds a second from the same funds.
If Stynx's own services stop answering, a crossing page that is already open can still exit: quotes and prices come from the swap rail, the proof from your browser. If the site itself is gone, the 24 words still hold the funds.
The sanctions check fails closed: no list, no entry quotes.

Road

Where the road is today.

Phase 0
Proof
2 October 2026
- Shield, release with change, and turn-back: each built in a browser and accepted by Zcash's test network.
- Measured on a laptop: about 4 seconds to prepare the proving key, about 9 seconds from a mined arrival to a broadcast shield, on six threads.
- Still open: the same on a mid-range phone.
Phase 1
First crossing
weeks 1 to 5
you are here
- Crowd Meter (layer 1 counted, layer 2 stated), Glass Box check, docs.
- Entry, shield, wait, exit to a Ghost, with partial exits.
- Sanctions check, limits, toll, recovery, the second door.

Phase 2
Token
after the first crossing completes
- $STYNX fair launch.
- Toll classes active at launch.
- 72 hours of full creator-fee buyback and burn, reported.
Phase 3
Growth
months 2 to 3
- Several Ghosts in one planned exit.
- Pre-signed, timed exits.
- One-click Papers, exposure watch.
Phase 4
Upgrade
months 3 to 6
- Exit through a second chain.
- Fee split in a contract with no owner.
- More entry assets, independent review.
Phase 5
Ecosystem
months 6 to 12
- Embedded crossing for wallets and terminals.
- A stable lane with no ZEC price exposure, as research.

Logbook

Decisions, and why.

Decision · Reason

Use Zcash's pool, build none: A crowd takes years. A new pool starts at one.
Toll 0.30%, at entry only: The source wallet is public anyway, and the exit stays plain.
No Stynx server is told where an exit goes: A server cannot log or leak what it never receives.
A refund address for every exit wallet: The swap rail is never given one Zcash address by the way in and a way out, nor by two ways out.
Two light nodes, one per side: A node learns what it is asked. Neither is asked about both sides.
The Crowd Meter says which layer it counts: Layer 2 is small at launch and cannot be counted yet. Passing layer 1 off as the whole crowd would be a promise.
The token never buys privacy: A deeper crowd for some is a shallower one for all.
Half of every net toll is burned: Burns tied to routed volume, not to emissions.
Product live before token: Ship the crossing, then the curve.
$50 to $10,000 per crossing: Small routes cost too much. Liquidity thins near $50,000.
A random key, written as 24 words: Any site can ask a wallet for the same signature again. A random key cannot be asked for, and it is not tied to wallet A.
A sanctions check, a size cap and Papers: Private by default, provable on request.

What gets watched

Arrivals on Robinhood Chain from ZEC, per week. It is the layer 2 crowd.
Crossings per week and the median wait.
The share of exits that were split.
Tolls collected and $STYNX burned, both published.

What is deliberately not built

A leaderboard. A public ranking of people who use a privacy tool defeats the tool.
Points or rewards for volume. Wash routes gain nothing and still pay the toll.

Limits

Honest limits.

Stynx separates two wallets. It does not erase either one.

What holds

The layer 1 crowd exists on day one and is not Stynx's to lose.
No pool, no custody, no exit endpoint: no contract to drain and no database that ties wallets together.
Every crossing and every ZEC holder arriving makes the next Ghost harder to single out.
Burns come from tolls and trading fees, each with a public transaction.

What does not

Layer 2 is small at launch. Early Ghosts sit among few.
You hold ZEC while you wait, and its price moves.
The current Zcash pool went live in July 2026, after a bug retired the previous one. It is young.
A Ghost that receives the whole amount can be matched by its total. The planner warns; it cannot forbid.
The count on the Crowd Meter is the Zcash side only. Against somebody who also watches the swap rail's payouts the crowd is the smaller layer 2, and nobody can count that yet.
In the first version an exit needs your browser open.
The swap rail sees the IP address that asks for an exit, this site's server the one that asks for an entry, each light node the one that uses it. Stynx cannot hide an IP address.
The key sits unencrypted in this browser's storage. Malware on the device, or anyone at the unlocked browser, can take it.
Privacy tools draw regulatory attention. Stynx checks the wallet you leave from against the public sanctions list, caps size and offers Papers, and it may still be restricted in some places.
Other teams on this chain work on private transfers. Stynx does not claim to be first, only to be exact about the crowd.

Other routes, and this one

Other routes:New shielded pools open with a crowd of one: Stynx:Routes through a pool that sees about 1,100 exits a day
Other routes:Exit only to the wallet you came from: Stynx:Exit to a fresh wallet, funded and ready to use
Other routes:Off-chain routers ask you to trust their logs: Stynx:The link is broken by a proof made in your browser
Other routes:Crowd size is never shown: Stynx:The Crowd Meter counts the crowd before you pay, and says what it leaves out
Other routes:Pooled contracts hold everyone's money: Stynx:No pool, no custody, no contract of ours involved
Other routes:A fee on every action: Stynx:One toll on the way in, the way out is free
