Wallet-gated rooms for OTC deals
A room only two wallets can enter.
Open a room for your counterparty's address and send them the invitation. To get in, they sign it with that wallet — so the person on the other side is the owner of the address you are dealing with, not somebody who copied a profile picture. Your browser checks the signature itself, and then the two of you talk directly, with nothing in between.
Impersonation is impossible
Fake accounts are how OTC deals get robbed: a copied avatar, a lookalike handle, a convincing tone. Here the door does not read a name. You write down one address when you open the room, and the only way in is a signature from that address — which needs the private key, not a resemblance.
Nothing to hand over
No email, no phone number, no Google, no password. The account is the wallet you already have, and the invitation is a piece of text you carry across yourself. There is no room record on our side to leak, subpoena or forget to delete.
Encrypted between the two of you
Voice, video, screen and chat travel on one direct WebRTC connection, encrypted with keys the two browsers negotiate between themselves. Read the safety number aloud once and you have checked, yourselves, that nobody is in the middle.
How it goes
- 01
Write down their address
It goes into the address bar after the # — the part of a URL browsers never send to a server. The room is opened for that counterparty and for nobody else.
- 02
Sign the invitation
One free, off-chain signature. It seals your wallet and this exact connection into one block of text. No transaction, no approval, nothing that can move a balance.
- 03
Send it anywhere
Telegram, Signal, email — it does not matter, because a stranger holding it can do nothing with it. On Pro that block becomes a five-character link instead.
- 04
They sign back, you check them
Their reply comes back the same way. Your browser recovers the address from their signature and compares it to the one you wrote down. Nothing vouches for them but the maths on your own machine.
- 05
Close the tab
The connection dies with it. There is no transcript anywhere to ask for, and nothing to press to be sure of that.
Free, and not the trial kind
The encrypted chat, the wallet check and the safety number are free and always will be, because they cost us nothing — they happen entirely between the two browsers, and the free room touches no server of ours at any point. What the paid plans add is the two things that do cost money. Pro turns the invitation into a five-character link, which needs somewhere to put it for the few minutes before it is collected. VIP adds voice, video and screen sharing over a relay, which is bandwidth billed by the gigabyte — and is what makes a call between two phones on mobile data connect at all.
