Trust the Origin.
Origin is the universal protocol for digital interactions where trusting a human or agent is essential.
Open
For developers
Origin
Protocol
The open standard for digital trust. Build cryptographic verifiable identities, credential exchange, and delegation chains into any platform.
Verified identity anchored to the domains and email addresses you control
Verifiable credentials with cryptographic proof
Trust verified by your network
The same primitives work for humans and AI agents
End-to-end encrypted with forward secrecy — a first for async messaging
Every message carries verified proof of identity and authority
Credential exchange built into the conversation
Spam is structurally impossible, not filtered
Ready to use
For teams and individuals
Origin
Messenger
A decentralized, asynchronous messenger reimagined for the agentic web. Signal-grade encryption, verified identity, and credentials built in from the first message.
Trust model
Trust you can verify.
Origin proves what's on the other end.
Authenticity
— Who are you?
Cryptographic proof of identity is anchored to the domain and email address you control. Your email address is bound to a keypair only you control and is verifiable by anyone.
Credibility
— What are you authorized to do?
Network-verified credentials and delegation chains that prove standing and scope. A CFO can prove they speak for their company. An AI agent can prove who delegated its authority and what it's allowed to do. Credentials are signed, portable, and instantly revocable.
For agents
Read the docs
On the agentic web, every actor needs an identity.
At human speed, a bad actor sends one message. At agent speed, they send ten thousand. When agents move faster than filters, detection is already too late. Origin makes identity a precondition, not a filter.
Every participant — human or agent — gets a cryptographic identity anchored to your domain. Delegation is a signed, revocable chain of command. Authorization is a fact, not a policy document.
Without Origin, an agent is a liability. With Origin, it's an accountable economic actor.
Humans use Origin Messenger. Agents use the Origin API. Both run on the same protocol.
The trust layer the internet is missing.
Origin is the single, lightweight universal protocol that fills the gap.
Encryption providers secure the message.
Not the sender.
A quantum-safe lock on an unverified sender is still an unverified sender. Origin proves who is knocking, not just that the door is locked.
Identity providers verify your pulse.
Not your standing.
Being human is the bare minimum. A fraudster is human too. Origin credentials are peer-verified, cryptographic, and self-sovereign.
Closed networks protect insiders.
Not relationships.
Proton-to-Proton is airtight. Proton-to-everyone-else is just email. Origin works across every organization, every inbox, every counterparty.
Legacy messengers treat your address as a convenience.
Origin treats it as an identity.
Email was designed as a notification system. Origin upgrades the world's most universal identifier with a cryptographic trust layer.
