Neurai Sign od Neruraiproject

Use Neurai's blockchain (XNA) to authenticate yourself using coins or tokens through digital signatures.

Neurai Sign is a simple browser wallet companion for Neurai (XNA) that lets you prove wallet ownership by signing messages.

It’s built for real-world sign-in and verification flows: websites can request a signature, you review the request, and approve it only if you want to. The extension supports both Neurai Mainnet and Testnet, shows your wallet address and balances, and lets you manage multiple accounts in one place.

Security is a core focus:

Private keys stay on your device
Keys are encrypted locally with your PIN
Signature requests always require your approval
Auto-lock protects access after inactivity
If you use Neurai and need reliable message signing in the browser, Neurai Sign gives you a clean, straightforward workflow without unnecessary complexity.
