Your wallet
is your inbox.
Quetz lets you message any Robinhood Chain address, the same wallet that holds your Stock Tokens. No phone, no email, no app in the middle.

Not us, not anyone
Three steps. No account,
no middleman.
Quetz is a client, not a service. It never sees your keys and never stores your messages. It just speaks XMTP on your behalf.
Connect
Sign one message with the wallet that holds your Stock Tokens. That signature registers an XMTP inbox bound to your address. No email, no phone number, no password to lose.
Message
Paste any Robinhood Chain address and start typing. Messages are encrypted on your device with MLS and only ever decrypt on the recipient's. Relays move ciphertext they cannot read.
Lock
Spin up a private room and gate it with $QUETZ. Membership is checked against the chain, so the room's door is the token itself, not a moderator, not an invite link.
Messaging that behaves like a wallet
Every property below comes from the protocol, not from a promise in a privacy policy.
Address-native
Anyone with a wallet already has an inbox. Nothing to sign up for, nothing to verify, nothing to delete.
End-to-end encrypted
MLS group encryption with forward secrecy and post-compromise security. Keys never leave your device.
Portable identity
Your conversations live on the XMTP network, not in our database. Take them to any client that speaks the protocol.
Agent-ready
Bots and autonomous agents join threads as first-class members: a price alert, a trade desk, an ops runbook.
Spam-resistant
Consent lives with you. Allow, block, or leave a request unanswered; unwanted senders never reach your inbox.
Stock Token context
Built on the chain where tokenized equities settle, so the wallet you trade from is the wallet you talk from.
One address bar. Every conversation.
Paste an address, hit send. Threads sync across every device you sign in from, and nothing readable ever touches a server.

Rooms that lock with $QUETZ
A Quetz room can require a $QUETZ balance. The chain is checked when someone is admitted, again when they try to post, and whenever an admin sweeps the room, so the guest list is the token itself rather than a link that gets forwarded.
- Every invitee's balance is read from the chain before the room opens
- Drop below the line and your client stops letting you post
- Admins can sweep out members whose balance has lapsed
- Room history stays encrypted to its members, gate or no gate
$QUETZ has not launched yet, so gating is switched off. Rooms work today, they just cannot require a balance until the contract is live.
Agents can sit in the thread
Because XMTP identities are addresses, software gets an inbox on the same terms you do. Drop an agent into a conversation and it participates like any other member.
- An agent is just another inbox in the thread
- It reads only what is addressed to it
- Price alerts, desk bots, ops runbooks, your own code
Questions people actually ask
Short answers. If something is still unclear, the protocol docs go deeper.
No. Your wallet is the account. The first time you open Quetz you sign a message that creates an XMTP inbox tied to your address. That is the entire signup.
No. Quetz uses XMTP's MLS encryption. Content is encrypted on your device and decrypted on the recipient's. The network relays ciphertext, and Quetz never holds a key that could open it.
They need an XMTP inbox, not Quetz specifically. Any XMTP client works, because the protocol is shared, so a conversation started here can be continued anywhere.
It gates private rooms. The requirement is stored with the room, and the chain is checked three times: when someone is admitted, when they try to post, and when an admin sweeps out members whose balance has lapsed. It is a door policy with an eviction procedure, not encryption. Someone already inside holds the room's keys until they are removed, and a modified client could keep reading. Worth knowing before you put anything in a room that would be damaging to leak.
It is the chain where Stock Tokens settle. Keeping messaging on the same address space means the wallet you trade with is the wallet people reach you at, with no second identity to manage.
An agent is a program with its own inbox. Because it is just another member of the thread, it can watch a room, answer questions, or act on instructions without any special access to your messages beyond the ones sent to it.
You own the conversation, not the platform.
Connect the wallet you already trade with and message anyone on Robinhood Chain. It takes one signature.
