Letter

Messaging that bypasses Telegram. Post-quantum sealed end to end, zero metadata, and money that moves inside the conversation. No email. No phone. No IP.

🔐 ML-KEM-768 + ML-DSA-65

🫥 Metadata-blind relay

💸 Send USDm in chat

🧅 Onion-only, no servers

New chat

Enter a @username or paste a MonerousD address. Your correspondent's identity is their wallet — no phone number, no email, nothing to leak.

Recipient

New group

A private group, sealed to each member individually — the relay only ever sees opaque letters, never who is in the group or how many. Invite by @username or address; they join the moment they receive it.

Group name Invite members (one per line) Discoverable @handle (optional)

Your profile

Published on-chain, signed by your wallet — only you can ever write it (the chain refuses any other key, cryptographically). Photo optional: without one, your avatar is derived from your address.

Your photo lives on the chain, inside your signed profile — no photo host, no CDN, nothing fetches from a third party (so viewing it can't leak anyone's IP). Downscaled to 128px.

Display name Bio DM fee for new contacts (USDm) — 0 = open DMs

Strangers must attach this payment to their first message. Real anti-spam: spam costs money, and the fee is yours.

Send USDm

A real, private on-chain payment to this contact. It clears your wallet's own approval, then a sealed receipt appears in the chat.

Amount (USDm) Note (optional)
