This page installs NeuraiHW, the official hardware-wallet software for
Neurai (XNA), onto a small pocket-sized device (the LilyGo T-Display S3).
Once it's installed, the device becomes your own offline wallet: your secret keys are
created and kept inside the device and never leave it — it simply approves and
signs your Neurai payments when you ask it to.
Everything happens here in your browser, talking to the device through its USB cable.
Nothing is sent over the internet. Just follow the three steps below.
This is how your wallet looks once it's set up:

STEP 1 · BEFORE YOU START
Can this computer do it?
Installing the wallet needs a browser that can talk to USB devices. Let's make sure yours can — these three things all need a green check.

STEP 2 · CONNECT
Connect your device
Plug the device into a USB port on this computer, then press the button below. Your browser will ask which device to use — pick it and continue.
Connecting for the first time?
A brand-new device connects on its own — just plug it in and press the button.
If your device already runs the wallet and won't connect, put it into install
mode: hold the BOOT button, briefly press RST
(reset), then release BOOT — and try again.
