Open to the whole world, and to whatever else is out there looking for a door.
Five ways to lock a channel
- No email or phone
- End-to-end encrypted
- Open source
- Web and Android
Communities
Rooms that feel alive.
Public channels for anything: your city, your game, the hobby nobody around you understands. Join in one tap and you are in the conversation.
No algorithm decides what you see. A room is people talking, in order. Nothing gets boosted, buried, or reshuffled to keep you scrolling.
Everything you expect. Replies, reactions, edits, pins, unread tracking, photos and files. History loads when you come back.
Yours to run. Create a channel in seconds. You moderate it, you set who gets in, and it stays yours if you walk away for a year.
Conversations are
personal property.
Not data to be harvested. Not content to be ranked.
Not leverage to be sold back to you.
Nothing to sign up for
A key is made on your device the moment you open the app. No email, no phone number, no password.
No central servers
Messages travel across a peer-to-peer network. There is no Pombo server to hack, subpoena, or switch off.
Nothing to take on trust
Fully open source, on web and Android. The encryption runs on your device and anyone can read how.
No cut of what you make
Joining a public channel is free. Paid channels charge what their owner sets, and every cent of it reaches the owner.
Ownership
You own everything you create.
Your account and your channels answer to your key, and to nothing else.
Your keys, your identity.
Pombo generates an Ethereum key in your client and encrypts it at rest. That key is your account. There is no row in a database somewhere with your name on it.
Nobody can suspend you. There is no account to disable, because there is no account to begin with, only a key you hold.
As many lives as you want. Separate identities for work, for a project, for the part of yourself that does not need to connect to the rest.
It follows you. Channels, contacts and settings sync between your devices, encrypted end to end on the way.

Channels belong to their creators.
Creating a channel registers it on Polygon, to your address, where the rules are set. You control who joins, what’s encrypted, and how long messages are stored.
You set the rules. Permissions, encryption and storage: all yours to configure.
You hold the keys. No one, including Pombo, can take your channels away.
Pombo is just the interface. If Pombo disappears tomorrow, your channels still exist on the network.

Or create your own.
A channel is a room with a lock of your choosing. Pick one when you create it and the network enforces it from then on.
Protected
One shared password, and the room is encrypted with it. Only the people who have it can read a word.
Closed
You keep the guest list. Members are approved by address and the chain enforces it.
Gated
Hold the token or the NFT and the door opens by itself. Nothing is spent. It is a balance check.

Put a price and a period on a channel and it becomes a subscription. Your writing, your signals, your community, behind a door you own.

It goes from your subscriber to you, wallet to wallet. No escrow, no balance to withdraw, nobody in the middle. Set the price in POL, USDC, DATA or a token of your own.
Direct messages
Message anyone.
Message anyone.
Just an address.
Giving out your Pombo address works the way giving out an email or a phone number works. Someone has your handle, and they can write to you.
No company behind it. Nobody issued the address, nobody keeps the directory, and nobody can suspend it, resell it, or hand it to whoever asks.
The envelope is sealed. The network carries your message without knowing who wrote it.
The inbox is yours. You set it up once, in a single paid step, and from then on it belongs to you.
Under the Hood
How Pombo works.
Explore the architecture, storage, security, and notification system that power decentralized messaging.
Multiple Streams.
No central servers
When you create a channel, a set of smart contracts is deployed on Polygon PoS. They manage permissions, metadata, and ownership of its data streams on the Streamr Network.
Who can join and who can publish is enforced on-chain. A message reaches everyone in the channel in real time, with no central server in between, and history lives on storage nodes of your choice.
Live signals (who's online, who's typing, peer-to-peer file transfers) travel through a separate ephemeral stream that leaves no trace.

Your messages,
your storage choice.
Private messages travel fully encrypted across the network. Storage nodes hold public and encrypted data, but they can never read your private content.

On your device
Either way, storage nodes hold only encrypted data. The keys never leave your device.
Encryption you
can verify.
All encryption happens on your own device, in both clients, using the platform’s built-in crypto. No external libraries, no hidden servers. The source code is open for anyone to audit.
Password Channels
Your password is transformed into a strong encryption key using 310,000 rounds of key stretching, making brute-force attacks impractical.
Direct Messages
DMs use key agreement between your account and the recipient's. Both sides independently compute a shared secret that no one else can derive.
Account Storage
Your private key is stored locally on your device, encrypted with your passphrase.

On the web this runs through the browser’s own window.crypto.subtle; on Android it is native Kotlin
Strong passwords matter. They protect your channels, your account and your backups, and there is no "Forgot password" button.
Push notifications.
Privacy layer added.
Notifications still reach your phone through Google or Apple. Every app needs that last mile. The difference is what they learn. In most apps they see who is messaging whom, and when. Here a relay layer strips that before it reaches them.
K-Anonymity
Tags are truncated so the relay sends the wake to every device that matches, hundreds at once. Google and Apple deliver it to all of them. Only each device knows if it's the real recipient.
Proof-of-Work Anti-Spam
Sending a notification requires solving a computational puzzle. No accounts, no API keys, just math.
Open-source Relays
Anyone can run a relay server. It can't read messages, doesn't know the sender's IP, and can't identify receivers.

Questions
The short answers.
Do I need to know anything about crypto?
To talk, no. A key is made for you in the background. You touch the chain three times: setting up your inbox, creating a channel, and subscribing to a paid one, and the app shows the cost first.
What does Pombo cost?
Using it is free. Creating a channel costs a Polygon network fee, cents, paid to the network. Paid channels charge what their owner sets, and all of it reaches the owner.
Who can read my messages?
The people in the room. Direct messages and private channels are encrypted on your device before they go anywhere, and the keys stay there. Public channels are public by design.
What happens if Pombo shuts down?
Your channels are registered on-chain, and your history lives on the storage cluster you chose: the default one, or a node you run. Neither is a Pombo server, because there is none. The protocol and the clients are open, so anyone can build another way in.
Can I use it on my phone?
Two ways. It runs in any modern browser and installs to your home screen. There is also a native Android client (real Kotlin, not a wrapped page) on the same protocol, so both talk on the same channels. It is in beta, so it comes as an APK from GitHub rather than from a store.
