Today: Users need a wallet app (e.g., MetaMask, Ledger, Phantom) or an external device.
Key management is outsourced and complicated → Beginners often give up.
With Nimiq:
Since the blockchain itself runs in the browser, the wallet function could be integrated directly at the browser level – just like a password manager.
This means that private keys are not stored in an external add-on or app, but in the browser profile itself.
This is what it could look like technically key management in the browser core
Browsers (Chrome, Firefox, Safari) manage Nimiq keys like passwords or certificates.
Access via biometric authentication (FaceID, TouchID, Windows Hello).
Standardized interfaces
Websites can communicate directly with the browser wallet via JavaScript (similar to navigator.credentials today).
No MetaMask pop-up, no extension required.
Synchronization
Keys can be encrypted and backed up using the browser’s existing cloud sync (Google Account, Apple iCloud, Firefox Sync).
Advantage: Users never lose their coins due to forgotten seed phrases.
Security Keys are never stored unencrypted on third-party servers → full self-custody.
Browser can fall back on hardware security modules (TPM, Secure Enclave).
Recovery possible via cloud backup or social recovery mechanisms.
Competitive advantage
Mass appeal: Everyone already has a browser – no additional app, no add-on, no ledger.
Simplicity: “Using crypto = opening a website.”
Exclusivity: Nimiq could be the first and only blockchain to be natively embedded in browsers.
In plain language:
Other chains also run in the browser (via RPC + wallet extension), but none run truly natively. Nimiq could say:
“We are the first protocol that the browser itself understands.”
Realistic strategy
Start with a partnership with smaller browsers (e.g., Brave, Opera, Vivaldi).
Integration as proof of concept: “Brave has Nimiq wallet out-of-the-box.”
Later: Put pressure on big players (Google, Apple) with the argument:
User-friendliness
Security
“Crypto = standard browser feature, like HTTPS”
This would make Nimiq make custody as natural as:
Passwords (password manager)
Certificates (SSL/TLS)
Cookies (session management)
