On Robinhood Chain, anyone with your address can read your portfolio and every trade. Shield your stocks into one pool, then hold, send and swap them with nothing showing up against your wallet. Dividends keep landing while you are inside.
Not audited yet. No token, no points, no airdrop. Robinhood stock tokens are not offered to US persons.
A brokerage never showed your statement to strangers. Tokenized stocks put your whole account on a public ledger: what you hold, what you sold on Tuesday, what you paid a contractor, and where the proceeds went.

sees the whole account, forever, from one address.
sizes up targets by balance before the first message.
watches a founder’s wallet and reads the company off it.
Deposit NVDA, AAPL, TSLA, AMZN, SPY or USDG into the Kasper pool. This step is public on purpose. It waits one hour in a queue, then joins the pool.
Send to a Kasper address, a string starting with kasper1. The recipient gets an encrypted memo only they can read.
Trade one stock for another, or for USDG. The pool does the trade on Uniswap in its own name.
Withdraw to any wallet, including a brand-new one. A relayer sends the transaction so your wallet is never the sender.
Each one is a single zero-knowledge proof, made in your browser in seconds.
Robinhood stock tokens pay dividends by raising a multiplier on the token, not by moving tokens. A shielded note holds raw units, so when the multiplier moves your note is worth more shares without any transaction. Nothing to claim, nothing to reveal.
The multiplier read 1.0 a week earlier. A dividend landed, and every raw unit of NVDA on the chain, shielded or not, became worth that much more of a share.
Kasper follows the Privacy Pools line of research rather than the mixer model. Every deposit is screened, waits an hour in public, and can only ever be refunded, never seized. Here is the hour.
Every deposit is checked against the stock issuer’s blocklist and a sanctions oracle before the pool accepts it.
A deposit sits in a visible queue for an hour. A screener can reject it in that window. After that, nobody has a lever over it.
A rejected deposit goes back to the wallet that made it. There is no other destination in the code. Rejected money never enters the pool.
Withdrawal addresses are checked the same way. A blocked address cannot receive an unshield.
Hand your viewing key to an accountant, an auditor, or a regulator who asks. They see every note you received: asset, amount, when. They cannot move a cent, and they cannot see what you did next unless you show them that too. Privacy from strangers, disclosure on your terms.
The app warns about each of these before you act. We would rather you read them here first.
You own tokenized stocks on Robinhood Chain and do not want your portfolio and trades readable by anyone with your address.
Contractors, founders splitting exposure, families. A payment should not double as a public disclosure.
You do not want positions front-run or copied by wallet-watchers.
On-chain stock exposure without broadcasting the book. Viewing keys and screening are the parts you will read first.
Pulled from the docs, word for word where it mattered. If one is missing, ask and it goes in.
No. A mixer takes money from anyone, holds it in a shared pot, and pays out with no questions asked. Kasper screens every deposit, holds it in a public queue for an hour where a screener can reject it (refunding the depositor, not seizing), screens every withdrawal address, and gives you a viewing key so you can show your history to whoever you choose. The privacy is against strangers reading the chain. It is not a way to hide from a subpoena.
No account, no form, no email. Connect, pick, shield. Everything after that happens inside the pool with nothing showing up against your wallet.
No token, no points, no airdrop. Robinhood stock tokens are not offered to US persons and neither is Kasper.
Any wallet on Robinhood Chain. Kasper never holds your keys and never sees your spending key.
NVDA, AAPL, TSLA, AMZN, SPY or USDG, and an amount. Round numbers are harder to trace later.
One hour in the public queue, then the position is yours alone. Send, swap or unshield whenever you like.
