# Introduction Introduction to Hardware Wallets Cryptocurrency hardware wallets are physical devices designed to securely store your digital assets, such as Bitcoin, Ethereum, and other altcoins. These devices offer a number of benefits compared to software wallets, which are programs that you can install on your computer or mobile device to manage your cryptocurrency holdings. Here are some of the key advantages of using a crypto hardware wallet: 1. Enhanced security: One of the main benefits of a hardware wallet is that it provides an additional layer of security to your cryptocurrency holdings. Unlike software wallets, which can be vulnerable to hacking, hardware wallets are stored offline, making them much harder for cybercriminals to access. 2. Easy to use: Most hardware wallets are user-friendly and easy to set up, even for people who are new to cryptocurrency. They typically come with clear instructions and a user-friendly interface, making it simple to manage your digital assets. 3. Backup and recovery: If you lose your hardware wallet or it becomes damaged, you can often recover your cryptocurrency holdings by using a backup phrase. This is a unique set of words that is generated when you set up your hardware wallet and can be used to restore your access to your digital assets if something happens to your device. 4. Compatibility: Hardware wallets are compatible with a range of different devices and operating systems, including Windows, Mac, Linux, and even smartphones. This makes it easy to manage your cryptocurrency holdings on the go. 5. Widely accepted: Most exchanges and other cryptocurrency-related businesses accept hardware wallets as a secure way to store and manage digital assets. This makes it easy to use your hardware wallet for a variety of different purposes, such as buying and selling cryptocurrency or participating in ICOs. In conclusion, a crypto hardware wallet offers a number of benefits compared to software wallets. Its enhanced security, ease of use, backup and recovery features, compatibility, and wide acceptance make it an excellent choice for storing and managing your digital assets. # Motivation Significance of the Problem and Opportunity The blockchain and distributed ledger technology (DLT) industry is experiencing rapid growth, which means that an increasing number of people will be using these technologies on a daily basis, often without even realizing it. Blockchain has a wide range of applications, use cases, and services which bring high level of security and trust to untrusted parties that need to transact over the internet. DLT accounts often hold real monetary value such as NFTs, Tokens, Cryptocurrency and other digital Assets, making them a target for hackers. Therefore, it is important to implement effective account protection methods, such as secure hardware wallet devices, to safeguard against potential threats. One of the most significant advantages of crypto is that users have full control over their accounts and can make transactions at any time without the need for approval from a bank or other authority. However, this also means that it is crucial for users to be responsible for the security of their accounts, as the theft of a private key or unauthorized access to an account could result in the loss of all funds without the possibility of recovery. To mitigate this risk, many people are turning to hardware wallets, which allow users to securely manage their cryptocurrency accounts without exposing their private keys. This is especially important for those who hold large amounts of cryptocurrency, as the use of a cell phone-based wallet may not provide sufficient security for such a high value. Hardware wallets are only used when a user needs to transfer funds or sign special transactions, and they are disconnected immediately after use to further enhance security. The hardware wallet industry is still in its early stages, and there is significant room for improvement. Some major issues Citadel Wallet is working on addressing include: * **Limited Feature Support:** Wallets have limitations in terms of storage capacity, performance, and the features they can support on various networks. Hardware wallets often try to support as many networks as possible, but this limits the number of DLT features they can support. On the other hand, Citadel Wallet prioritizes supporting the most advanced DLT technology Hedera, and provides full support for it. In the future, simply sending crypto will not be sufficient and it is important to have a wallet that can support advanced DLT features. * **Security:** The most commonly used hardware wallets in the cryptocurrency industry often utilize secure elements with a lower CC EAL5+ safety certification level. These wallets also typically utilize generic microcontrollers, which act as a bridge between the secure element and the external world and the user. However, these generic microcontrollers can potentially be exploited by hackers as an attack vector, allowing them to access the device and potentially sign unauthorized transactions. * **Ease of Use:** Hardware wallet solutions with small sizes often come with very small screens that are not touch-sensitive and have limited buttons for interaction. These wallets can be difficult to use due to their non-intuitive user interfaces and can be time-consuming to navigate and configure. On the other hand, larger size screens offer a more comfortable experience, but they come in the form of larger devices that consume more power and have shorter battery lifetimes. It is unlikely that users will want to carry another phone-sized device in addition to their smartphones, limiting the environments in which these wallets can be used. * **Battery Lifetime** – By implementing the latest low power microcontroller technologies, optimizing hardware and software design, and incorporating innovative mechanical and hardware design techniques, the power consumption of hardware wallets can be significantly improved. Additionally, using high capacity batteries with compact sizes can also contribute to longer battery life. These strategies will help to maximize the efficiency and lifespan of hardware wallets operating on battery. The Citadel Wallet aims to apply lessons learned from previous generations of hardware wallet technologies to create a secure, reliable, and user-friendly experience for interacting with the Hedera public network. It serves as a modern companion device that allows users to access decentralized applications and securely sign transactions. To ensure optimal performance, the hardware components of the Citadel wallet have been carefully selected for their ability to support ample dynamic memory, encrypted intra-core communication, long battery life, a full color touchscreen display, and all necessary cryptographic operations for transactions on the Hedera network. Additionally, a software development kit will be provided to make it easy for both users and developers to access the core features of Hedera and integrate the Citadel wallet into their distributed applications. **Citadel Wallet's key value propositions:** * High Security EAL 6+ Secure Element * Secure Microprocessor with Trust Zone * Full support for all possible Hedera services and transaction types * Intuitive touchscreen and User Interface * Physical buttons to approve transactions * Full color 1.28” round display * Long battery life: 12 Days * USB-C Communication * NFC Wireless Communication * Integrated Storage * SDK to integrate with software wallets such as Hashpack, Blade, My HBAR Wallet, etc. # Why Hedera Hedera Network's Characteristics Hedera is a distributed ledger technology (DLT) platform that aims to offer fast, secure, and fair transaction consensus for a variety of Enterprise and Web 3 use cases. Some key features and advantages of the Hedera network include:
1. **Speed:** Hedera can process hundreds of thousands of transactions per second, making it the fastest DLT in the world. Currently network is throttled down to 10k+ Tps with plans to raise the throttle in the future as more applications onboard and TPS starts to rise. 2. **Security:** Hedera uses a novel consensus algorithm called "hashgraph" which is based on a type of directed acyclic graph (DAG) and is designed to be secure and resilient against all types of attacks. Hashgraph consensus is the only public DLT network which was able to achieve the highest form of security possible called Asynchronous Byzantine Fault Tolerance (ABFT). 3. **Finality:** Because of Hashgraph consensus algorithm, Hedera network is able to achieve complete transaction finality within 3-5 seconds. Competing blockchain networks on the other hand are probabilistic, which means transactions are never 100% confirmed but users become more certain over time that transactions won't be reverted. 4. **Leaderless:** Hedera network is leaderless, which means no single node determines or dictates the order of transactions at any point in time for rest of nodes in the network. All nodes come to the same consensus independently which makes the network resliliant against DDoS attacks. 5. **Fairness:** Hedera's consensus algorithm is designed to ensure that all transactions are processed in a fair and deterministic manner and each message or transaction submitted to the network is fairly ordered and timestamped by all participating nodes independently. 6. **Cost:** Transaction fees on Hedera network are extremely low and on average cost $0.0001 per transaction. They are also fixed for each transaction type and are pegged to a US Dollar but paid in HBAR. Hedera network is designed to provide a sustainable and predictable fee model to Enterprises and business who can plan their expenses ahead of time regardless of HBAR price volatility. 7. **Governance:** Hedera is a decentralized platform that is operated by a consortium of trusted organizations called "governance council members." These members play a crucial role in the operation and development of the platform, but they do not have sole control over it. There will ever be up to 39 Council Members in Hedera network, which are term limited to 2 times and 3 Years each terms. Besides Council nodes Hedera network will add more community nodes over time and eventually opening up the network to anyone who would like to run a node. 8. **Energy:** Hedera network has been recognized as the most energy-efficient public distributed ledger technology (DLT) network in the world, according to a study conducted by University College London (UCL). This makes it a highly sustainable and environmentally friendly option for businesses and individuals seeking a secure and efficient means of conducting digital transactions. 9. **Flexibility:** Hedera supports a variety of use cases including DeFi, NFTs, Gaming, Tokenization, Payments, CBDC, Data Integrity, Digital Identity, Stablecoins, Supply Chain, IoT and more. It also offers APIs and SDKs that make it easy for developers to build on the platform. 10. **Compliance:** Hedera is designed to meet regulatory requirements and has partnerships with various organizations and agencies to ensure compliance with relevant laws and regulations under different jurisdictions. 11. **Scalability:** Hedera is designed to scale as the number of users and transactions on the platform increases, making it suitable for large-scale deployments. Initially network will scale vertically by increasing numbers of transactions per second processed by a genesis shard. Eventually Hedera will scale horizontally by adding as many shards as there is demand for. We are excited to be launching our Hardware Wallet exclusively on Hedera, a reliable and scalable network that is essential for Web 3 to reach the mainstream. We believe that Hedera's robust infrastructure is crucial for the success and widespread adoption of Web 3, and we are proud to be able to bring these benefits to our users. # Certifications, Audits and Licenses **Secure Audits Public Report by Kudelski Security:** {% file src="/files/B6SX9Tn6VKWlNRstugJD" %} **CE Declaration of Conformity:** {% file src="/files/W4EZQlzfOkTEzr18jeZj" %} **UK Declaration of Conformity:** {% file src="/files/MYNAZNNvmJxQXGkm8V45" %} **FCC Certification:** {% file src="/files/IzBuRhyi6S9rv65k8JSd" %} **ISED Canadian Certification:** {% file src="/files/CkeGbYqRoPW539fkAs9x" %} **Australia and New Zealand Declaration of Conformity:** {% file src="/files/I1zGsV1hGRBiPnU3z5Gh" %} **IEEE MA-L OUI Assignment is:**

Citadel Wallet is utilizing a microcontroller based on a newly released ARM Cortex-M33 core architecture developed for IoT and embedded applications that require high security and low power consumption. Advanced dual core technology allows separation of secure and non-secure applications running on the same chip without risking security. The processor has a built in TrustZone security extension for hardware-enforced isolation, a coprocessor interface, memory protection units, and a floating-point unit. The Cortex-M33 processor with TrustZone and memory protection is PSA certified providing security assurance for applications that require high levels of protection.
The Cortex-M33 microprocessor achieves an optimal blend between real-time determinism, energy efficiency, software productivity, and system security which opens the door for many new applications and opportunities across diverse markets including blockchains. M33 microprocessor is based on the ARMv8-M architecture which reduces the complexity of developing secure embedded solutions that scale all the way from the smallest IoT device to complex SoCs. When M33 core is in Secure state, it can access both Secure and Non-secure memories. If the ARMv8-M architecture with Security Extension is implemented, the processor starts up in Secure state. When the core is in Non-secure state, it can access Non-secure memories only. Secure core will allow to use a TRNG (True Random Number Generator) block to generate truly random FIPS 140-2 compliant private/public key pairs required for cryptocurrency account creation. MPU (Memory Protection Unit) and KMU (Key Management Unit) will allow secure storage of keys and management of them for different needs such as encrypted wireless communication, off chip memory communication and handling of public keys. Secure core of the microcontroller will interact with off chip Secure Element for submitting messages that need to be signed and returned. Non-Secure core of the microcontroller will be responsible for running the general application for the wallet communication with the PC or mobile device through USB, BLE or NFC. It will handle user inputs through touch or button user interfaces and drive the LCD. # Secure Element Secure Element utilized in Citadel Wallet has an independent Common Criteria EAL 6+ security certification up to OS level and supports both RSA & ECC asymmetric cryptographic algorithms with high key length and future proof ECC curves. Latest security measures in this secure element protect the chip against invasive and non-invasive attacks. For a comparison, Ledger hardware wallets are certified to only up to EAL 5+ security level.
Secure element is specifically designed for blockchain, secure IoT, government ID and secure key storage applications. It requires a host controller, which will communicate with the secure element through I2C interface and make key operation requests such as key creation, message signing and verifying. It generates the private/public key pairs for asymmetric encryptions internally to the secure element and private keys never leave the chip. Some of the major features of the Secure Element include: * CC EAL 6+ and SESIP4 certified HW and OS * FIPS 140-2 certified platform with Security Level 3 and Security Level 4 related to Physical Security of the HW * Effective protection against advanced attacks, including Power Analysis and Fault Attacks * Multiple logical and physical protection layers, including metal shielding, end-to-end encryption, memory encryption, tamper detection * RSA and ECC asymmetric cryptography algorithms, future proof curves and high key length, e.g. Brainpool, Edwards and Montgomery curves * AES and DES symmetric cryptographic algorithms for encryption and decryption * HMAC, CMAC, SHA-1, SHA-224/256/384/512 operations * Extended temperature range for industrial applications (-40 °C to +105 °C) Hedera accounts require ED25519, RSA-3072 or ECDSA cryptographic pairs for account creation and interaction with the network. Secure Element used in Citadel Wallet support all options. # Storage To add support more features in the future in the wallet additional external storage space might be required. Having larger storage will also allow for more graphical objects, ability to store images for NFTs and design a better user experience. External Flash Memory will be used to store non-secure applications only and will never store private keys associated with cryptocurrency accounts. All communications between Secure Microcontroller and the off-chip flash memory will be handled through OTF (On the Fly) encryption, which means data that exits microcontroller through the communication interface will be already encrypted and when retrieved will be decrypted in the microcontroller. AES keys are stores in the microcontroller and will never leave the secure domain. ## Storage Spec: * **Capacity:** 16 MBytes * **Type:** Non-Volatile Flash # Battery Hardware wallet is equipped with a small, 200 mAh rechargeable Lithium Ion battery. According to our estimates, this battery should be able to power the wallet for approximately one week without needing to be charged, assuming an average daily usage of one hour. This makes it an ideal choice for those looking for a reliable, convenient way to store and manage their digital assets. Citadel Wallet is designed to be portable, thanks to its battery-powered feature. This allows users to take their device with them wherever they go, making it convenient for those who need to access their crypto assets while on the move. Whether you're traveling for business or leisure, the Citadel Wallet offers a secure and convenient way to manage your digital assets. ## Battery Spec: * **Capacity:** 200mAh * **Type:** Li Ion * **Lifetime:** About a week with an average of 1 Hr/Day usage # Wallet Comparisons Below table provides side by side comparison of Citadel Wallet with 2 other popular hardware wallets in the market Ledger X and Trezor T.
