What stays private
Robinhood Chain is a public ledger. Gloam adds a vault on top. Here is what that does and does not hide.
At a glance
While in the vault
Your open wallet no longer shows that amount. Harder to read your full bag from the street.
Private send (live)
Pay someone inside the vault with a receive tag. The chain sees a transfer proof, not “Alice paid Bob 0.01 ETH”.
When you enter / exit
Shield and cash out touch the public chain. Someone can see that the vault was used.
Private trade (live)
Vault ETH → vault stock with a sealedSwap proof. Size is private by default (min-out floor, not your exact size). Pair and caller still public.
Via market adapter
Cash out → public swap → re-shield. Swap size is public on that edge. Prefer Private trade when a pool is empty or you want size privacy.
Cash out
Unshield publishes asset, amount, and destination. Stay in the vault to stay private.

We aim to hide
- How much you hold while it is in the vault
- Who paid whom inside the vault (private send, live on testnet)
- Trade size on private trade (default max size privacy, see sealed trade)
The public can still see
- That someone used Gloam (shield / sealedSwap / unshield txs)
- Asset pair on a private trade (e.g. ETH → TSLA), not the size
- When money went in or out of the vault (and amounts on cash out)
- Caller address on each tx; timing clues if few people use the system
We will not promise
- Invisibility from law or courts
- Safety if your phone is compromised
- Privacy if you clear the browser note and lose the secret
- Strong anonymity with almost no users
