S&P 500NvidiaAppleTeslaUSDGUniswapRobinhood ChainOn Robinhood Chain a wallet is a brokerage statement anyone can open. Every stock, every size, every trade.
Noma keeps your holdings off the public chain and puts only the settlement on it.
You see your portfolio. The chain sees one vault, one net trade per batch, and a total for each stock. Nothing about you.
A shared vault, a hidden ledger, batched trades and a withdrawal you control.
Your positions are entries in a ledger the chain never sees. Each one belongs to a fresh key only you can derive. The chain stores a single total per stock and nothing about you.
Connect a wallet, put in a stock or USDG, trade it inside the vault and take it out to any address. Live on Robinhood Chain.
Open the app →Every position gets a fresh address. When you withdraw, that address has no history and no link to your other holdings.
Buyers and sellers of the same stock are matched inside the vault first. Only the difference reaches the market, so the market never sees your order.
If the operator ignores you for 24 hours, or goes silent for 48, anyone can freeze the vault. Then every holder withdraws with a proof they make themselves.
Every withdrawal is checked against the vault's last total and signed with the holder's own key. A batch that claims more than the vault holds is rejected.
Every batch publishes one total per stock: how much everyone holds together. The vault compares it to its own balance, so the ledger can never claim more than the vault has, and nobody can read who holds what.

Tesla—Short answers. The docs have the long ones.
Every batch is checked against the vault's balance, and every withdrawal against your own signature.
