private messaging, built on bitcoin·in beta
no phone number. no signup. just
an inbox that's actually yours.
Sign in with a Bitcoin wallet or an email code. Your identity becomes a private inbox.
§ how it works
three steps. one tap. no account.
sign in
A wallet or an email code. No password, no phone.
your address is your inbox
Share it like a username. No directory to hack or shut down.
only you can read it
Messages open on your devices alone. Not ours. Not anyone’s.
§ three ways to send
three ways to send. two no other app can.
- [01]
speak-now
Everyday messages, free. Like any chat app — minus the phone number.
- [02]
pay-to-reach
Charge strangers a small fee to reach you. The sats go to you, not us.
- [03]
seal-til-block
Write now, opens later — locked until a future point on Bitcoin’s clock.
the questions we hear most. answered plainly.
- do I need to own bitcoin?
- No. Chatting is free, and an email code is enough to sign in.
- can you read my messages?
- Never. They’re encrypted on your device — we see only scrambled text.
- will you touch my coins?
- No custody, ever. Payments go straight to your wallet.
- how is this different from signal?
- Your identity is a Bitcoin address, not a phone number. Nothing to phish or reset.
§ open your inbox
your address is your inbox.
your wallet is your sign-in.
the chain is your clock.
No phone. No account. No custody. Free to start, and yours to keep.
