In the vast landscape of cryptocurrency storage solutions, three hardware wallets stand out for their unique features and commitment to security. In this review, we’ll delve into the features of the Coldcard Mk4, the Keystone Crypto Wallet, and the Ngrave Zero, evaluating their strengths and weaknesses to help you determine which one is the best fit for your needs.
Coldcard MK4 Physical Crypto Wallet
In the realm of cryptocurrency storage, the Coldcard Mk4 stands out as a hardware wallet designed specifically for Bitcoin. Developed by a team of experts in Toronto, Canada, the Coldcard Mk4 offers robust security features and user-friendly functionality. Let’s delve into the details of this wallet and explore its strengths and weaknesses.
Unique Security Features
- Air-Gap Functionality: The Coldcard Mk4’s hallmark feature is its air-gap functionality, which allows it to operate fully offline. This means that the wallet is never exposed to the risks of online hacking, as it doesn’t need to be connected to an internet-connected device at any point during its usage, from seed generation to transaction signing. This impressive security feature is made possible by the wallet’s full support of Bitcoin Improvement Proposal 174 (BIP174), a standard that enhances the security of Bitcoin transactions.
- Dual Secure Element Chips: Another unique security feature of the Coldcard Mk4 is its use of dual Secure Element chips from two different manufacturers. These chips are specifically designed to securely store sensitive information, making the Coldcard Mk4 particularly robust against potential security threats.
- Trick PIN Options: Beyond its air-gap functionality, the Coldcard Mk4 offers additional security-enhancing features, such as support for Micro-SD cards for effortless backups of your wallet’s seed phrase and the ability to conduct Bitcoin transactions offline. The wallet also provides a range of “trick PIN” options, including a “duress PIN code” that directs users to a separate wallet containing decoy Bitcoin keys, serving as a deterrent to potential intruders. Additionally, the “Brick Me” PIN option seals the gateway to the wallet’s secure elements, rendering them inaccessible.
User-Friendly Interface
The Coldcard Mk4’s user interface is straightforward, displaying white text on a black OLED screen. This design provides a clear and concise user experience, particularly during critical tasks like signing or exporting transactions.
In summary, the Coldcard Mk4 is a specialized hardware wallet designed for users who prioritize the security and convenience of their Bitcoin transactions. With its air-gap functionality, dual Secure Element chips, and range of security-enhancing features, the Coldcard Mk4 stands out as a strong contender in the market for Bitcoin wallets.

Mastercard Partners with Mercuryo to Expand Support for Non-Custodial and Physical Crypto Wallets
Published date: 09 September 2024
Global payment leader Mastercard has joined forces with European crypto payments provider Mercuryo to broaden support for non-custodial wallets, including physical crypto wallets. This collaboration introduces a euro-denominated debit card, enabling users to spend cryptocurrencies like Bitcoin stored in self-custody and physical crypto wallets at over 100 million merchants worldwide within the Mastercard network.
Non-custodial wallets, particularly physical crypto wallets, allow users to store their cryptocurrency without relying on centralized platforms such as exchanges or banks. In contrast to custodial wallets, where a third party holds the private keys, physical crypto wallets give users full control and responsibility for securing their funds.
Physical Crypto Wallets: The Ultimate Security Solution
Physical crypto wallets, also known as hardware wallets, have gained significant popularity among crypto enthusiasts who prioritize security. These devices store private keys offline, providing an additional layer of protection against cyber threats and unauthorized access.
“The integration of physical crypto wallets into our payment ecosystem marks a significant step towards enhanced security and user control,” said Christian Rau, Mastercard’s Senior Vice President for Crypto and Fintech Enablement. He added that the collaboration with Mercuryo aims to bridge the gap between blockchain technology and conventional payments, with physical crypto wallets playing a crucial role.
Users of physical crypto wallets can now benefit from the convenience of spending their digital assets at Mastercard-accepting merchants while maintaining the robust security offered by these hardware devices.
The partnership aims to offer consumers a seamless, reliable, and secure way to spend digital assets wherever Mastercard is accepted, with physical crypto wallets at the forefront of this innovation.
Mastercard’s latest initiative with Mercuryo builds on their successful pilot program launched in August, where the firm collaborated with MetaMask, a leading self-custodial crypto wallet, to offer crypto debit cards. The new venture extends this functionality to users of physical crypto wallets, addressing the challenges faced when navigating between blockchain assets and traditional payment systems.
The Mastercard-branded Spend card, compatible with various non-custodial solutions including physical crypto wallets, comes with fees set by Mercuryo, including a €1.60 issuance fee, a €1 monthly maintenance fee, and a 0.95% off-ramp fee.
Mastercard’s Continued Push into Crypto
Mastercard’s support for physical crypto wallets is part of its broader strategy to embrace blockchain technology and cryptocurrencies. The payment giant recently announced that its new “Crypto Credential” service has gone live, making peer-to-peer crypto transfers more intuitive for average users, including those using physical crypto wallets.
Last year, Mastercard emphasized that crypto and blockchain can bring significant value to financial industries, particularly when addressing security and ease of use issues to build trust. The integration of physical crypto wallets into their payment ecosystem aligns perfectly with this vision, offering users enhanced security and control over their digital assets.
As the crypto landscape continues to evolve, the role of physical crypto wallets in providing secure, user-controlled storage solutions is likely to grow. Mastercard’s partnership with Mercuryo represents a significant step towards mainstream adoption of these devices, bridging the gap between traditional finance and the world of cryptocurrencies.
