Platform diagram - Neuron Agent API

These diagrams show how the Neuro platform is structured — the layers that make up every Neuron, and how Neurons, clients, and services connect across a federated network.

The platform stack

Every Neuron hosts the full platform stack. The layers build on each other — each one depends on the ones below it.

Layer	What it provides
The Neuron	The federated runtime. Handles all communication and interaction across domain boundaries.
Neuro-Ledger	Distributed, auditable persistence. Records signatures, state changes, and events.
Legal Identities & Smart Contracts	Verified actors and governed agreements tied to real identities.
Payments & Tokenized Assets	eDaler payments and Neuro-Feature tokens, built on top of the full stack.

The federated network

Neurons are independent nodes operated by different organisations, federated together into one network. Clients connect to the Neuron they are registered on and can interoperate with participants on any other Neuron in the network.

Client connection types

Client	How it connects	Typical use
Neuro-Access App	XMPP client-to-server (C2S)	End-user digital identity and wallet
Agent API client	HTTPS REST (Agent API)	Back-end services, server-to-server integrations
LegalLab	XMPP client-to-server (C2S)	Developer tool for designing contract templates
XMPP client	XMPP client-to-server (C2S)	Direct messaging and IoT integrations

How federation works

Neurons connect to each other using XMPP server-to-server (S2S) links — the same protocol used by the broader XMPP network. This means:

A contract can be signed by parties registered on different Neurons.
A token can be transferred between users on different Neurons.
An identity on one Neuron can be verified and trusted by another.

No central coordinator is required. Trust flows through the network based on the relationships between Neurons and the cryptographic signatures on identities and contracts.

Where to integrate

Depending on your use case, you connect at different points:

If you are building…	Use…
A back-end service or server integration	Neuron Agent API
A Neuron extension or custom package	Neuron Development
A payment or checkout integration	Neuro-Pay
A desktop tool for contracts and templates	LegalLab
A mobile app with identity and wallet	Neuro-Access App
