MetaMask now compatible with NGRAVE hardware wallet

MetaMask has announced its integration with NGRAVE on Extension and Mobile, enhancing security of users’ digital assets. By leveraging both MetaMask hot wallet and NGRAVE ZERO hardware wallet, users can benefit from convenience and accessibility, while maintaining the highest levels of security.

Increased security

Because hardware wallets are offline, they significantly reduce the risk of being hacked, and unauthorized access to users’ private keys. Hardware wallets, sometimes called “cold wallets” also serve as a secure backup for private keys, ensuring that primary assets remain safe even if the hot wallet is compromised. Since users retain total control over their private keys, the integration expands self-custody management of their crypto assets. Additionally, as hardware wallets are online by default, MetaMask stays up-to-date with alerts, to minimize the risk of phishing attacks and malware that typically target hot wallets.

Convenience and accessibility

Users can quickly access and manage their funds through their MetaMask hot wallet, allowing them to buy, sell, transfer, bridge, stake, and more – while signing fully offline via their hardware wallet. This avoids compromising the security of larger holdings stored in the hardware wallet. MetaMask wallet allows for seamless transactions, without moving assets between different wallets frequently. A streamlined integration between hot and cold wallets provides a smoother user experience, making it easier for novice and experienced users to manage their assets versatile and securely.

Note: for the MetaMask browser extension, the minimum required version to use the NGRAVE integration is v. 12.3.0. For the MetaMask app, the minimum required version is v. 7.31.1.
