Let’s get real: Your DMs aren’t yours.

Every message you send is hosted on servers owned by a handful of tech CEOs. Jon Stewart nailed it: “There’s not one communication app not controlled by one of six individuals.”

We’re done letting them own our conversations.

2/7

Come build the most secure and private messaging network in the world—owned by the people who build it and use it.

“Decentralized messaging is the foundation for a free society.” — @ethereumjoseph 

🚫 No censorship.
🔐 No backdoor surveillance.
🛡️ Owned by you, not a CEO.

XMTP isn’t just a protocol—it’s sovereign communication.

3/7

How it works:

💸 Micro-fees paid by apps in USDC are automatically distributed to node operators.
⚡ Msgs are delivered in milliseconds via an offchain broadcast network
✨ Consensus on critical state is maintained using Arbitrum Orbit on @base.
