Demo Day
10 SEP 2026Two days of building. Then you show what's possible.
Demo Day is what the 7th and 8th are for. Selected teams take the stage at King's Garden to showcase their products and demonstrate working prototypes, and show how AI and blockchain solve real business and societal problems.
Selected teams present, the room asks questions, and the conversations carry on afterwards. That is where the visibility, the honest feedback and the first customer usually come from. Build like you're going.

Build with Neuro
FIG. 2.1The hard half is already built. Spend your two days on the interesting half.
Verified identity, legally binding signatures, smart contracts, tokens and payments: four groups on one API, backed by the same keys and the same Neuro-Ledger. Not four vendors. Turn the dial and see what each one costs you in code.
Verified legal identities
People, organisations and machines, validated by Trust Providers and bound to a cryptographic key, so they hold across domain boundaries.
Legally binding signatures
Sign contracts or arbitrary binary data, with the legal standing that implies and an auditable record of who signed what.
Smart contracts & tokens
Create from approved templates, collect signatures across the network, mint tokens with full event history.
Wallet and payments
eDaler peer-to-peer, programmatic, and built for AI agents that pay for the APIs they call.
KYC/KYB as a service
Run compliance checks on people and businesses through the same API, in the hours you have rather than the quarters it usually takes.
Federated by design
Neurons talk to Neurons over XMPP, so contracts get signed across node boundaries.
Identity
Application note · getting your credentials
The Agent API is served from your Neuron's own domain. There is no shared central URL. Every deployment has its own host, and every host issues its own API key and secret.
At FIRSTBLOCK-ATHON, Neuro is your Neuron operator. Your host, API key and secret are handed to you at Netlight on the morning of 7 September. Read the quickstart before you arrive and you'll be making your first calls by 09:30.
Note: the Agent API is for trusted back-end clients that can protect keys and secrets. For browser-based flows, use CreateWebForm.

All POST · JSON bodies · every path prefixed /Agent/ · HMAC-signed to create and log in, JWT bearer thereafter. Every group above opens in the interactive OpenAPI playground, where you can fire real requests from the browser.

What to build
AND WHO'S BUILDINGFour things that fit in 48 hours.
Shapes that lean on the parts we already solved, so your two days go into the idea rather than the plumbing.
A product passport that survives resale
Tokenize an object, attach its lifecycle to a state machine, let every owner read the full event history.
An agent with a wallet
Give an AI agent a verified identity and a balance, and let it pay for the APIs it calls, with an audit trail.
Agreements that sign themselves
Two verified parties, one contract from a template, signatures collected across federated Neurons.
Onboarding without the compliance detour
KYC/KYB as an API call, with the identity attached to everything the user signs afterwards.
Already running on this.
Five products in production today, built on the same layer you'll be handed on the 7th.
- Wawcash
Fuel credit made accessible to drivers in Senegal.
- Creturner
Turning carbon credits into trusted digital assets.
- Innova
A trusted marketplace for assets as different as gold and coffee.
- Neuro Pay Travel
Simplifying payment flows in travel.
- Digitala Lagkassan
Payments for clubs and associations.

ORDERING INFORMATIONRegister, then read. In that order.
Step 1 · Secure your spot
Free, limited, and reviewed by the hosts. Get this bit done today and the rest can wait.
Apply to join ↗Step 2 · Understand the platform
Start where the docs start. Fifteen minutes here before the 7th is the difference between building at 09:30 and building at lunch.
Introduction — what Neuro is What is the Neuron? Trust model Glossary Get started ↗Step 3 · Make your first call
Authentication first — HMAC to create and log in, JWT for everything after. Then walk whichever of the four flows sits closest to your idea.

Neuro-Access, Neuro-Assets and Neuro-Pay: secure identity, asset digitalization and smart payments, built by Trust Anchor Group. The hackathon is one door into a much bigger platform, and we'd love to show you the rest of it.
