Came across PrivaMesh – interesting take on private messaging

[hoseinm339]

Been looking around for messengers that don’t rely on the usual phone number / email signup and don’t keep everything on their own servers. Ran into PrivaMesh the other day and figured I’d share it here since it sits at that weird intersection of crypto and privacy tools.

It’s an iOS app (App Store) that calls itself a serverless end-to-end encrypted messenger. The big points that stood out:

- No phone number or email needed at all. You just generate a key on the device and that’s your identity.
- There’s no central message server run by the project. Encrypted messages get sent as Solana transactions.
- Everything personal (keys, contacts, chat history) stays on your phone, locked in the Keychain. Keys never leave the device.
- Uses the same general crypto approach a lot of people trust (X3DH handshake + Double Ratchet).

I like the idea in principle – no company holding your contact list or message metadata, and the delivery layer is just the blockchain. Of course it means you need a tiny bit of SOL for fees, and the user base is still small, so it’s not something you’d switch your whole group to tomorrow. But as a concept for people who actually care about not leaving a trail on someone else’s servers, it feels different from the usual suspects.

Website is privamesh.org if anyone wants to check the details or the GitHub. Curious if anyone else has tried it or has thoughts on using Solana txs this way for messaging

If I don't need my number to sign up does it have any link to my contacts? How would I get people to talk to on there, I'm guessing it'll be through usernames.

You will never get your entire friend group to be into a privacy focused messenger, they will be there specifically for you, you just need to convince them to download it to send/receive messages to/from you. This is why I think the need to have SOL to make transactions may discourage some people.
