THE BUY BUTTON / EXPERIMENTS

ZK Stock.
GME put on sunglasses.

A tokenized stock. A zero-knowledge pool.
A very small round trip.

An independent, unaudited experiment using a separate pool based on RAILGUN contracts on Robinhood Chain. Not an official Robinhood, GameStop or RAILGUN product. Not anonymous stock ownership. No new stock token is issued here.

Real tokens. Tiny test. No guarantees.

Only use GME you can afford to lose. Maximum per deposit in this interface: 0.0001 GME (not a contract-wide cap). Native ETH on Robinhood Chain pays gas. No yield, stock purchase, bridge or reward claim is offered here.

Current pool fees: 0.25% in + 0.25% out, paid to the experiment operator. A 0.0001 GME deposit returns approximately 0.000099500625 GME, excluding gas. Token issuer rules, eligibility, freezes and corporate actions still apply.

Read the trust and privacy limits before depositing

This instance has not had an independent deployment audit. Its owner can change fees, token blocking and verification keys; compromised or malicious administration can jeopardize funds. A note backup cannot protect against a broken contract, issuer freeze or compromised device.

The pool is tiny. Deposit and withdrawal amounts, timing, sender, recipient and gas payments are public. This page uses your connected wallet to submit both transactions: linking them may be easy. It has no private relayer. There is no anonymity guarantee.

Your spending note is generated and encrypted in your browser, not sent to our server. The recovery file plus password controls the note. Lose either and you may lose the deposit permanently. The operator cannot recover your note. Do not upload your EVM wallet key or seed phrase.

This experiment is public. Visiting it or using a zero-knowledge proof does not make you anonymous. Public RPC providers can observe requests. Stock Tokens are tokenized debt securities, not direct ownership of GameStop shares. Use only if you are eligible under the issuer's applicable terms.

No wallet connected

Balance: —

Use an EVM browser wallet with GME and native ETH on Robinhood Chain (4663). Every transaction needs your approval.


One file = one deposit. Never reuse it for another deposit. Save the file and password separately before continuing. No wallet seed phrase is requested.


No note loaded

You can send directly to someone else. Double-check the address and network; transfers cannot be reversed. The connected wallet pays gas. The recipient address and withdrawal amount are public.

Connect only when you are ready. Nothing happens automatically.

Proofs run locally and can take a minute on slower devices. Keep the tab open. A delayed receipt is not a failed transaction: check before retrying. A new deposit is blocked after any ambiguous submission.

FIELD NOTES / THREE-MINUTE READ

The stock went incognito.
The issuer didn’t.

We gave a microscopic amount of tokenized GME a deeply unnecessary side quest: enter a zero-knowledge pool, move between encrypted notes, then return to a public wallet. It worked in our controlled mainnet test.

GME put on sunglasses. It was still the only GME in the room.

That is the joke. Here is the interesting part.

A normal brokerage balance lives inside the broker’s product. An ERC-20 token can encounter contracts its issuer did not design. Someone outside that company can write an experiment and ask: will this asset work here, too?

Our narrow test says this token could pass through this deployed pool at that time. It does not say every token will, every wallet is eligible, or tomorrow’s issuer rules will be identical.

Proof, not a magic invisibility cloak.

The pool records commitments. A holder uses a private note to create a mathematical proof that they can spend an unspent commitment, without publishing that note’s secret. The contract checks the proof and prevents spending the same note twice.

But hiding a secret is not the same as hiding a person. A small pool, distinctive amounts and the same wallet paying gas make for a terrible disguise. This interface is an experiment in execution—not a promise of financial secrecy.

The wrapper travels. Its obligations travel too.

Robinhood describes Stock Tokens as tokenized debt securities providing economic exposure, not legal ownership of the underlying shares. A different contract does not make issuer controls, redemption terms or eligibility requirements disappear.

The interesting implication is composability: financial assets can become material that independent builders experiment with. That opens a design space. It also opens a lot of ways to lose money if the engineering is bad.

So we started very small. No “untraceable stocks.” No revolution in a trench coat. Just one token, one working round trip, and a button that apparently needed a hobby.

still on. slightly overdressed.
