The secure element and important parts of the processor are covered by epoxy at the factory. In addition, it ensures that there is zero transaction leakage. SecuX wallets contain Infineon Chip CC EAL 5+ Secure Element, the highest grade for the financial industry to protect your private keys. You can get more information about their hardware from the Github repository. They use STM32F205VG chips with a true random number generator (RNG). This prevents brute force attacks and provides additional security to private keys. In addition, for protection against physical tampering, they use the secure chip ATECC608A. BitBoxīitbox uses the ATSAMD51J20A micro-controller with a true random number generator. You can check the detailed procedure to upgrade here. Then, the SD card has to be inserted into the wallet. In Ellipal wallets, you have to download the updated firmware from the manufacturer’s page and copy it to an SD card. Furthermore, firmware updates are an important part of increasing cryptocurrency support and updating the firmware. Furthermore, they are planning to open-source the firmware for community review. It uses custom firmware, which security experts have verified. The metal casing helps reduce the range of private keys while making a brute force attack and guards the radio frequencies that an attacker could pick. Ngrave provides a multi-layered anti-tempered hardware device made up of high-end material. Trezor Model T consists of a micro-controller or one chip or for storing and generating the private keys. In addition, it has a micro SD card slot. Trezor uses an ARM Cortex-M3 processor 120 MHz, with custom software. Ledger WalletĪlso, read Ledger Nano S vs Trezor one vs Trezor T vs Ledger Nano X Trezor The Secure Element contains an STM32 microcontroller (MCU) that acts as a router between the secure Element and peripherals. Ledger uses a distinctive hardware architecture, BOLOS (Blockchain Open Ledger Operating System), and specialized chips called Secure Elements. ![]() ColdcardĬoldcard wallets do not require a battery. It takes two hours to charge the battery fully. SecuX offers a 600 mAH Li-polymer battery with up to seven hours of use and three months of idle time. You need to plug it into a device such as a laptop to make it on. BitBoxīitbox wallets do not use a battery. The battery can be charged using a USB cable. EllipalĮllipal consumes a 1400 mAH battery with a standby time of 259 hours. In addition, it uses a USB-compatible battery charger. Ngrave uses a 1200 mAH (Ultra-Efficient Low Power) battery. Instead, they consume power through a USB connection. It provides a battery life of 8 hours if in continuous use, but it extends up to three months if it is kept idle. However, Ledger Nano X consumes a battery of 100 mAh, which you can charge by connecting a USB cable to a PC or laptop. Additionally, if you wish, you can connect it to Coldcard Adaptor, a 9V battery. Instead, it draws energy from a USB power pack or AC power adapter. ColdcardĬoldcard wallets do not need to connect to a computer or smartphone. Additionally, you can connect via USB Type-C for SecuX V20 or USB-Micro B for SecuX W20/W10. Prokey uses a USB Type Micro-B to connect to any internet-enabled device such as a Desktop, laptop, or phone. Additionally, they provide a USB C to A adaptor. BitBox02 uses a USB-C port which is attached to the device.
