Voice messages
Record right in the chat and listen before you send. Your contact plays it as soon as every part is in, and you choose the sound quality in the settings.
Technologies
Chat on the chain. Sealed end to end.
Trai Messenger is built into the Tenrai Wallet. Write, talk, react and play with any Tenrai address, sealed with post-quantum encryption.
ML-KEM-512
Post-quantum handshake
Every chat opens with ML-KEM-512, NIST security category 1, standardized in FIPS 203.

Chat servers
There is no messenger server: the Tenrai network itself carries every message, fully decentralized.
60 s
Voice messages
A minute of speech fits in about 18 KB of Codec 2.
1 phrase
For all your chats
Your recovery phrase brings every chat back, on a phone or a computer.
How a chat starts
- 1
Start a chat
Enter an address, scan its QR code or pick a contact from your address book, and write a first message.
- 2
They accept
Your chat lands under Requests on the other side. When they accept, both wallets share the chat keys.
- 3
Chat privately
From then on every message is sealed end to end with XChaCha20-Poly1305. Only the two wallets can read it.
Everything a chat needs
Long messages
Write long texts in one go. The wallet sends them in parts on its own, and your contact reads one message, whatever order the parts arrive in.
Answer and quote
Answer a specific message, and both of you see it quoted above your answer. A tap on the quote shows where it stands. On a phone, swipe a message to the right to answer it.
Reactions and emoji
React with 👍 ❤️ 😂 😮 😢 🙏, and both of you see it under the message; tap it again to take it back. The emoji picker sits right next to the text field.
Forward
Pass a text or a voice message on to another chat. It arrives marked as forwarded, and the name of whoever wrote it stays with you.
Play Traiball
Challenge a contact to Traiball, a turn-based physics game played right in the chat. Every move is a sealed message, there is no time limit, and the game follows you to every device.
Your chats live on the chain
Every message is a small payment that carries its words in the payload, so the chain itself keeps the chat and there is nothing to back up. Use as many addresses as you like: give each contact a different one, and every chat still lands in the same wallet, whichever of your addresses it reaches.
Private where it matters
Sealed texts
Nodes, explorers and the API carry only sealed bytes, never your words.
No impersonation
A wallet accepts a message only from the side that sent it, so nobody can write in someone else's name.
Open by design
The first message of a chat travels in the open and carries your key. Who writes to whom, when, and how long a message is stay visible on the chain too.
You stay in control
Requests first
Anyone can write to any address, but a request costs its sender a fee, and nothing more reaches you until you accept.
Block and delete
Block an address or delete a chat in one step. Both act on your device only.
Your Messenger ID
One ID for your wallet on every device, such as TRM-4CA0-35E2-6A78-1786-FDC8-D8CA-0D7B-F39F. It is derived one way from your recovery phrase and reveals nothing about it.
Password if you like
Messages go out without your password by default. One setting asks for it before every message.
