Are Hardware Wallets Really Impenetrable?
And Which One Tops the List?
Your crypto could be at risk. Millions of dollars worth of crypto-related assets have been stolen by scammers, and you could be their next victim.
Countless NFT holders, with BAYC holders being the most infamous, have fallen prey to phishing scams, malicious websites and wallet drainers.
You may not think much of it, owing their mistakes to stupidity and carelessness, thinking how you’d never fall for similar scams if you were in their shoes. But don’t be mistaken, even the most experienced on-chain experts are susceptible to security breaches.
These scams aren’t just unique to NFT (or BAYC) holders. Various wallet drainers, either through phishing websites or malicious smart contracts, have the sole purpose of getting you to connect your wallet and sign transactions for them to steal your coins.
No matter how experienced or smart you think you are, you should always equip yourself with the best on-chain security practices possible, and one of the ways you can do so is by using a hardware wallet.
Hardware Wallets
Hardware wallets are physical, pocket-sized vaults for your crypto assets. They store your private keys – cryptographic sequences that let you access your crypto-assets – offline in a protected area of a microcontroller.
Hardware wallets epitomize the principle of self-sovereignty, and while this empowers individuals with full control and unrestricted access to their assets, it also transfers the burden of security onto them. This form of 'cold storage' reduces your exposure to the hacking risks associated with 'hot wallets', which are online methods of storage like Metamask.
There are a lot of hardware wallets to choose from. So, let's delve into some that we think are the best in the industry, from ones you may have not heard of to the most popular ones, focusing on their unique attributes, advantages, and potential downsides.
NGRAVE ZERO
In the rapidly evolving landscape of hardware wallets, NGRAVE ZERO is quickly setting itself apart as a game-changer. Promising an unrivaled level of security, it employs an entirely air-gapped approach that earned it an EAL7 security certification.
Supplemented with protective measures such as light sensors, pin protection, biometric scanners, and tamper-proof technology, NGRAVE ZERO's security offering outclasses many of its peers, while retaining a user-friendly interface encased in a robust, military-grade metallic shell.
Moreover, NGRAVE ZERO worked with the Interuniversity Microelectronics Centre (IMEC) and The Computer Security and Industrial Cryptography (COSIC) group, along with Jean-Jacques Quisquater - a distinguished cryptographer cited in Satoshi's Bitcoin Whitepaper - to produce its ground-breaking technique for private key generation and recovery, aptly dubbed the "Perfect Key".
The "Perfect Key" complements the NGRAVE GRAPHENE, creating a unique recovery system that eliminates third-party risk. This approach ensures that users, and only users, have exclusive access to their recovery phrase, a level of security unseen in the hardware wallet domain.
Admittedly, NGRAVE ZERO's staunch dedication to security comes with a higher price tag, and its offline-only operation might restrict its appeal to users seeking convenience. Nevertheless, for those prioritizing ironclad security, the device's novel features and robust architecture make a compelling case.
GridPlus Lattice1
The GridPlus Lattice1 stands out in the hardware wallet landscape, eschewing the usual USB-stick design for a 5-inch TFT touchscreen. This choice reflects the device's intended use as a desktop-based wallet, although this does mean typing on the tilted screen can be somewhat cumbersome.
The key innovation of the Lattice1 is its two-pronged internal architecture, designed to minimize potential security threats. It contains a General Compute Environment (GCE) for internet connectivity and a Secure Compute Environment (SCE) that is insulated from the outside world by a tamper mesh. The SCE handles crucial tasks such as signing transaction messages and controlling the display, and in the event of a physical attack, the tamper mesh triggers a complete data wipe.
Complementing Lattice1's security features are SafeCards, offering a secure storage option for seed phrases. Each SafeCard is PIN-protected and features a digital certificate issued by GridPlus. Unlike traditional written seed phrases, the cards refuse interaction with cloned or counterfeit SafeCards, further bolstering security.
Nevertheless, potential users should be aware of Lattice1's constraints. The device needs a constant power source, currently supports only Bitcoin, Ethereum, and EVM chains, and its physical dimensions may deter those looking for a portable solution.
Furthermore, the $397 price tag could be a stumbling block for some. Yet, for those who prioritize advanced security features and user-friendly touchscreen interaction, the Lattice1 could make a valuable addition to a home or office setup.
Ledger Nano X
The Ledger Nano X, the flagship product from Ledger, shares the limelight with Trezor as a pillar of the hardware wallet landscape.
The Nano X is capable of supporting over 1,800 distinct digital assets. In terms of security, the device comes equipped with a secure element chip certified to CC EAL5+ standards, reinforcing its safeguarding capabilities. Beyond the confines of wire-related connectivity, it also provides wireless connections via Bluetooth to both desktop and mobile devices, thus offering flexible usage across multiple operating systems from Windows to iOS and Android. Compared to Ledger's basic model, the Nano S, the Nano X provides a wider array of features, which is reflected in its $149 price tag.
However, despite its advantages, discussions, and doubts surrounding Ledger's recent moves are important to take into account for a well-rounded choice:
Ledger recently rolled out a service dubbed Ledger Recover, crafted to facilitate users in the retrieval of their misplaced secret keys.
This announcement of this service, though seemingly advantageous, stirred significant ripples in the industry as it presented an aspect of centralization and doubt over how much self-sovereignty Ledger devices actually provide, which prompted a notable portion of users to renounce their devices.
Ledger Recover Controversy
Ledger Recover operates as an ID-based key recovery service that archives users' seed phrases and requires a passport or national ID to confirm identity. Critics argue that the presence of a code path to transmit private key material over the internet, whether used or not, could expose users to increased security risks. The initiation of this service has stirred controversy, owing to the potential security hazards and a previous data leak incident at Ledger in 2020.
A cornerstone rule in the realm of cryptocurrency self-custody is the confidentiality and offline safeguarding of private keys. Ledger's latest move deviates from this principle, raising concerns about the possibility of hackers acquiring private keys or authorities compelling users to disclose their private keys.
Such a turn of events has discouraged a considerable number of users, guiding them towards alternative solutions such as Trezor and NGRAVE. This inclination is reverberated across different community channels and social platforms.
Trezor Model T
As a pioneer in the sphere of digital asset security, Trezor stands as the epitome of secure crypto storage. Its flagship offering, the Trezor Model T, emerges as one of the best choices for a crypto wallet.
Introduced in 2013, Trezor has continually proven its mettle by delivering a product that, to date, has not fallen victim to successful remote hacks. This track record, corroborated by third-party security audits, highlights Trezor's prominence as the gold standard in secure crypto wallets.
The Model T, retailing at $219, offers compatibility with over a thousand cryptocurrencies. The wallet can be managed via an online interface available for both desktop and mobile platforms, or through a specially designed Trezor suite application for desktop. The reach of Trezor is further extended through its integration with web 3.0 wallets, such as Metamask, and a strategic alliance with software wallet service Exodus. However, despite its premium features, support for iOS is currently not available.
This collaboration with Exodus ingeniously blends the user-friendly interface of Exodus with the high-security framework of Trezor. Another feature of the Model T is its touch screen, facilitating the direct entry of sensitive data, such as pin codes and recovery phrases.
