What is the Keystone Cold Wallet?
The Keystone Cold Wallet is a dedicated hardware device that helps you store and manage your cryptocurrency assets securely offline. It operates as a cold wallet, meaning it never connects directly to the internet. It protects your private keys from online threats such as hacking or malware. Keystone achieves this air-gapped security by using QR codes or a microSD card to transfer transaction data, so your sensitive information stays isolated from networked devices.
You can use the Keystone Cold Wallet to manage over 5,500 cryptocurrencies and tokens, perfect for a diverse portfolio. It supports major coins like Bitcoin, Ethereum, Dogecoin, Litecoin, and many others, including tokens and NFTs on several blockchains.
Through compatible wallets, Keystone also integrates with EVM (Ethereum Virtual Machine) and non-EVM chains, Cosmos, Solana, Sui, Aptos, and Cardano.
The Keystone wallet’s initial cost is $129. This is quite expensive for a hardware wallet, but not without reason. The wallet features a large display that shows you your crypto assets without connecting to a phone or computer.
However, you should be aware of some limitations. The wallet requires separate microSD cards for specific operations and cannot be used while charging, which some users find inconvenient during extended sessions. Battery life is also a consideration. And naturally, you must back up your recovery seed securely. Losing the device could mean losing access to your assets.

Keystone Wallet Timeline 📅
The company that would become Keystone was founded during the Bitcoin bull market by Discus Fish and Changhao Jiang. At this time, it operated under Cobo Wallet. Its headquarters were in Beijing, with additional offices in Shanghai, Xi’an, and Seattle.
The team launched its first premium hardware wallet, Cobo Vault Ultimate, after a successful Indiegogo crowdfunding campaign. This device was among the first in the industry to meet American military standards for robustness (MIL-STD-810G).
Keystone (then Cobo Vault) released its second-generation hardware wallet, focusing on global Bitcoin enthusiasts. This model maintained the air-gapped QR code system but was more affordable and accessible, and it marked the start of collaboration with the Bitcoin community on QR code standards.
The company received a Web3 Foundation grant to integrate the Cobo Vault with Polkadot.js, expanding compatibility with the Polkadot ecosystem.
Cobo Vault officially rebranded as Keystone, reflecting a renewed focus on open-source development and broader ecosystem integration.
Keystone addressed blind signing issues for Ethereum, integrated with MetaMask, and expanded support for major cryptocurrencies and tokens. The wallet became known for robust multi-signature solutions and enhanced security features.
Keystone 3 Pro was announced, with pre-sale beginning August 8. This third-generation model featured triple Secure Element chips, a longer warranty, fully open-source software, and improved battery design.
Keystone relaunched under its current brand, led by CEO Lixin Liu and CTO Aaron Chen. The Keystone 3 Pro was officially released, featuring a large color touchscreen, triple Secure Element chips, open-source firmware, and support for multiple blockchains including Bitcoin, Ethereum, and Solana. Previous Essential and Pro models were discontinued.
Keystone Hardware Wallet Security & Features
Air-Gapped Architecture
Keystone Wallet’s air-gapped architecture centres on complete physical and digital isolation from any networked environment. The air gap technology isolates your digital device from the internet and other connectivity technologies, meaning you never connect the device to the Internet, Wi-Fi, Bluetooth, USB, or NFC. It keeps your private keys offline at all times.
Being air-gapped sharply reduces the risk of malware, phishing, or remote hacking attempts.
When you want to send cryptocurrency, you start by creating a transaction on your online wallet. The transaction details appear as a QR code or a file, which you transfer to your Keystone device using its built-in camera or a microSD card. The Keystone wallet then signs the transaction internally and stores your private keys. It never exposes your keys to the connected device.
After signing, the wallet displays a new QR code or generates a file containing the signed transaction. You then scan or transfer this to your online wallet to broadcast the transaction to the blockchain.
Multi-Layered Secure Elements
Keystone’s multi-layered secure element architecture forms the backbone of its hardware wallet security. The Keystone 3 Pro uses three independent secure element chips sourced from different manufacturers. Each chip is EAL5+ certified, which is a high security standard used in banking and government applications.
The secure elements operate in a coordinated trust architecture. Each chip handles distinct security-critical tasks. One chip generates cryptographic keys using physical entropy sources, such as thermal noise and quantum tunneling. Another chip manages transaction signing by operating with isolated cryptographic modules. The third chip validates firmware integrity with TPM 2.0 standards for secure boot and update processes.
Technically, each secure element is a 32-bit ARM Cortex-M0 microcontroller. It includes 256KB of embedded flash memory, 16KB of ROM, 16KB of SRAM, and 4KB of dedicated SRAM for cryptographic algorithms. The chips support various cryptographic functions, including AES (128/192/256), RSA (up to 4096 bits), ECC, DES/3DES, and SM series algorithms.
Hardware random number generators (HRNG) compliant with FIPS 140-2 ensure that key generation is truly random and unpredictable. Performance metrics show that a 2048-bit RSA key can be generated in 2.3 seconds, while a 256-bit ECC multiplication completes in 7.4 milliseconds.
Using three separate secure elements means an attacker must compromise all chips simultaneously to access sensitive data. This redundancy raises the cost and complexity of attacks to a level that is currently computationally infeasible. Keystone further incorporates physically unclonable function (PUF) technology so that cryptographic keys remain unique and cannot be extracted or duplicated.
Anti-Tamper and Self-Destruct Mechanisms
Keystone wallets incorporate advanced anti-tamper and self-destruct mechanisms to protect your assets against physical attacks and unauthorized access. The device uses PCI-grade anti-tampering technology, which surrounds all core integrated circuits and secure element chips with a specialized security mesh and capacitive grid.
This system continuously monitors the integrity of the device’s casing and internal components. If the wallet detects any attempt to open, probe, or manipulate the hardware physically, it instantly triggers a self-destruct protocol.
The self-destruct mechanism erases all sensitive data, including private keys and wallet access information, within a fraction of a second. Independent testing has measured this wipe process at under one second.
The wallet also responds to multiple incorrect PIN entries or suspicious activity by activating the same memory wipe. Some models allow you to manually trigger the self-destruct feature if you suspect your device is compromised.
Open Source Transparency
Keystone made its firmware, hardware schematics, and secure element code publicly available. You can review the firmware’s source code on platforms like GitHub, where Keystone maintains repositories for the primary device and the secure element chips. If you’re critical of transparency, you can always look up the code.
Keystone Wallet’s firmware is written in Rust and C, with blockchain operations and cryptographic functions implemented in Rust for reliability and performance. The project also uses FreeRTOS as the operating system; you can access the code structure, documentation, and even testing tools.
Keystone publishes its hardware design, including circuit diagrams and the bill of materials. You or any independent developer can audit the device’s physical and software security. The company has also released third-party audit reports, uncommon in the hardware wallet industry.
Biometric Authentication
Keystone hardware wallets integrate biometric authentication to add a personal layer of security to your device access. The wallet uses a capacitive fingerprint sensor that stores your fingerprint template in encrypted form within the secure element.
When you enroll your fingerprint, the sensor captures multiple images and creates a composite template. The system allows you to register up to five different fingerprints. You can choose which fingers to use or allow trusted family members access in case of emergency.
The sensor compares your fingerprint scan to the stored template using a secure matching algorithm during each authentication attempt. The matching process takes less than 500 milliseconds and operates entirely within the secure element, so your biometric data never leaves the chip or gets exposed to the main firmware.
If the fingerprint does not match after a set number of attempts, the wallet locks itself and requires a PIN for further access.
Large Touchscreen Interface
The Keystone wallet features a 4-inch IPS touchscreen with a 480-by-800-pixel resolution. The screen supports multi-touch gestures and clearly displays detailed transaction information, QR codes, and settings menus.
You interact with the wallet much like you would with a modern smartphone, using taps and swipes to move through menus, enter PINs, and confirm actions. The interface uses large, well-spaced buttons to reduce the risk of input errors, especially when reviewing or approving transactions.
The touchscreen also boosts your ability to verify transaction details. You can fully view recipient addresses, amounts, and network fees before confirming any action. The display shows smart contract data for complex transactions so that you can spot discrepancies or potential scams.
The high brightness and wide viewing angles make the screen readable in various lighting conditions, whether indoors or outdoors. The familiar responsive interface gives it an edge over other cold wallets in the market.
Comprehensive Transaction Verification
Keystone wallets prioritize comprehensive transaction verification to protect your assets from accidental or malicious transfers. Before you approve any transaction, the device displays all relevant details on its screen, including recipient address, transaction amount, network fees, and, for smart contracts, decoded contract data.
The wallet parses and presents this information in a human-readable format, so you do not have to interpret raw hexadecimal data or blindly trust external software.
This verification process is significant for complex transactions in decentralized applications, token swaps, or NFT transfers. Keystone uses on-device parsing to decode smart contract calls and token standards like ERC-20 and ERC-721.
You can review the exact function being called, the contract address, and the parameters involved. If the transaction data does not match your intentions, you can reject it before signing. The wallet stores a history of recent transactions so you can cross-check past activity if needed.
Multi-Signature and Multi-Seed Support
In a multi-signature setup, you can require two or more devices or users to approve a transaction before it is executed. This approach is beneficial for managing shared funds, organisational treasuries, or high-value accounts. Keystone integrates with popular multi-signature platforms like BlueWallet, Sparrow Wallet, and Gnosis Safe.
When you use Keystone in a multi-signature arrangement, the device decodes and displays detailed transaction information, including transaction IDs, addresses, fees, and transfer values. This transparency helps you verify every aspect of a transaction before signing, so the risk of mistakes or malicious activity stays minimal.
The Keystone 3 Pro model introduces multi-seed support that lets you manage up to three separate seed phrases on a single device. Each seed phrase can represent a completely independent wallet, and you can toggle between them by entering the corresponding PIN at startup.
You can separate savings and daily spending, and even create a decoy wallet for added security. Most hardware wallets only support one seed phrase at a time.
Wide Asset and Wallet Compatibility
Keystone supports over 5,500 cryptocurrencies, including Bitcoin, Ethereum, Solana, Cosmos, Cardano, and major EVM and non-EVM chains. It integrates with popular software cryptocurrency wallets like MetaMask and BlueWallet, allowing you to manage diverse assets from one device.
Supported assets are discussed shortly after in detail.
Limitations
While effective for security, Keystone’s air-gapped architecture introduces extra steps to every transaction. You need to scan QR codes or use a microSD card to transfer data between your wallet and a computer or mobile device. Scanning for each transaction can feel slower than wallets using USB or Bluetooth connections.
The device does not support charging and usage at the same time. If the battery runs low during a session, you must pause your work to recharge. Battery life is sufficient for routine use, but frequent signing or extended sessions will surely put it to the test.
Keystone also does not offer built-in features for staking, swapping, or earning yield directly from the hardware wallet. You need to rely on external software wallets or platforms for these functions.
Firmware updates require careful handling. You must download updates to a microSD card and install them manually, which adds another layer of responsibility. There’s a faster USB update method that requires a non-air-gapped approach.
If you lose your recovery seed, you cannot recover your assets. While valuable for security, the self-destruct feature will permanently wipe your wallet if triggered, so you must always store backups securely.
Keystone Wallet – Supported Coins

Before transferring less common tokens, you should always check the latest supported asset list on the official website or app.
How Does the Keystone Wallet Work?
The Keystone Wallet works as an air-gapped hardware wallet that keeps your private keys completely offline. You start by setting up the device, creating or importing a wallet, and securely recording your recovery seed. The device never connects to the internet, Wi-Fi, Bluetooth, or USB, so your sensitive information remains isolated from online threats.
To receive cryptocurrency, you select the coin or token on the Keystone device. The wallet generates a unique receiving address and displays it as a QR code. You share this address with the sender. Once the network confirms the transaction, your funds become visible when you connect Keystone to a compatible software wallet.
To send assets, you initiate a transaction using a software wallet, such as MetaMask or the Keystone Companion App. You enter the recipient’s address and transaction details into the software wallet. The software wallet generates a QR code containing the unsigned transaction. You scan this QR code with your Keystone device, which displays all transaction details for your review.
After confirming, you sign the transaction on the Keystone using your fingerprint or PIN. The wallet then generates a QR code with the signed transaction. You scan this code back into the software wallet, which broadcasts the transaction to the blockchain.
Keystone’s workflow never lets your private keys leave the device or touch an internet-connected environment. You manage assets, sign transactions, and verify details entirely offline. Regular firmware updates and secure backup practices further protect your funds.
