A supplier issues a Digital Product Passport, the buying company receives it into its own wallet, and a customs office verifies it at the border. No account, no wallet, no setup — pick how you would like to see it.
The whole flow as an animation: three roles, one credential, and the path it travels. Nothing to click, nothing to read.
The same chain on the real screens, and you play every link in it: issuing the passport, clearing it at the border, building on it, then buying the result.
The Nexus app itself: your own wallets, your own credentials, nothing simulated. Everything the demo stands in for is set up here for real.
