Stock tokens on Robinhood Chain settle on a public ledger. Every position, entry, exit and running balance is readable by anyone with a block explorer, permanently and without consent. That is a worse privacy posture than the market these instruments were built to mirror, where only the venue sees the tape.

RhMask is a privacy layer for those assets. It gives holders a way to receive unseen using ERC-5564 stealth addresses derived entirely in the browser, a way to pay and be paid privately through a three-scan QR flow that needs no server, and a way to be paid in stock tokens for securing the protocol. No component takes custody, and no server ever sees a private key.

The privacy claim is narrow and deliberate. RhMask unlinks identity from receiving addresses. It does not hide settlement, does not obscure amounts, and is not a mixer. Every surface in the product states which of those applies.
