Frequently asked questions
HASHWallet provides a stronger security level than other hardware wallets due to several key features:
- It’s a non-programmable device. This feature creates a really secure environment for signing transactions and the safeguard of the keys.
- The private key is not known even by the user, and there is no way to extract it from the card. You can’t steal what you don’t know. This makes HASHWallet invulnerable to external attacks.
- Public/Private keys are generated inside the card through a random process, which cannot be replicated. No external seeds are used to generate keys.
- Its large screen of electronic ink allows to visualize all the details of the transactions and validate them, avoiding any possibility of fraud or identity theft, and it complies with the philosophy “What You See Is What You Sign”.
Yes. As an Open Source Project, it promotes collaboration between users and is open to developers and third parties in the future. We can integrate with other platforms such as exchanges and will offer APIs to work with HASHWallet system.
Key recovery and access
HASHWallet comes with two additional cards named Recovery Cards. When the device is first initialized, it will pair with the Recovery Cards via NFC, so these will store a Recovery Seed. Also, during this set-up process the card will generate a Recovery Key, which will be stored on the eSignus Vault. In case of losing the device, simply purchase a new HASHWallet and recover the keys from one of the Recovery Cards and the Recovery Key.
It is an encrypted code that is generated during the HASHWallet activation process. The Recovery Seed is stored inside a Recovery Card, and serves the purpose of recovering, once combined with the Recovery Key, the public and private keys in case of loss of the device.
In the rare event that eSignus ceases to operate, there would be a period where HASHWallet users could download their Recovery Key and store it by themselves.
In case you lose your Recovery Cards, you can purchase new ones through the official HASHWallet store. Once you have them, you must connect to your eSignus account and link HASHWallet with your eSignus Vault account, so the Recovery Seed will be generated and pair them again with your smart card. Your keys will be safe again.
If you lose your phone, simply install the App on a new mobile device and pair it again with the smart card.
If the password is lost, simply use the card as a double authentication factor (2FA) to access the app.
HASHWallet is a totally secure device, and your assets will always be protected against any hacking attempt. Although the private key is stored on the card, it is totally inaccessible from the outside; not even the user himself can read it. Therefore, you can’t steal what you don’t know.
The device and its technical specifications
HASHWallet has a format proper for bank cards, sized 85.60 × 53.98 mm and 1.5 mm of thickness. The Recovery Card also use the same size but with 0,76 mm of thickness, and complies with the ISO/IEC 7810.
HASHWallet complies with the IP67 protection level against dust and water. This results in a solid and durable device.
The card includes a Bluetooth antenna and an NFC reader, which allow wireless communication with other devices in a secure way.
Bluetooth connectivity establishes encrypted two-way communication with the smartphone or computer to receive transactions to be signed and returned once signed or rejected after reading on the e-Ink WYSIWYS screen.
NFC connectivity allows the recording of the Recovery Card, as well as receiving your data for the recovery of HASHWallet in case of loss of the original card.
The use of this NFC chip as a payment method is planned for future developments.
Also, HASHWallet includes a wireless charger that serves as a connection to a computer at the same time, to synchronize the card with the desktop application.
Remember that HASHWallet is a non-programmable device, and the keys that it stores cannot be accessed or modified from the outside.
HASHWallet incorporates a dedicated microprocessor for performing cryptographic operations such as generating recovery key and recovery seed in a non-replicable random way and every process related to confirming user operations. It is built into the smartcard with strong physical security measures.
Being a non-programmable device is one of HASHWallet’s essential security features. Therefore, the user must acquire a new device to have successive updates and improvements. To facilitate the upgrade, eSignus will offer its users an interesting discount for the renewal of their device.
HASHWallet is a simple device; it allows the user to view a transaction and decide to sign it or not. This simplicity is its greatest strength since it is impossible to alter a transaction at any time.
The process has two stages: the first is the construction of the transaction, which is mounted on the App. Once set up, this is transferred to HASHWallet which must be switched on and linked to the device and the active App. Once the transaction has been received on the screen, we only have to accept it through our fingerprint and it will be transmitted to the Blockchain via Bluetooth, using the device with the App as a communication channel.
If a transaction is left incomplete, this transaction does not exist.
- If it is incomplete in the App, it will wait for the user to finish it.
- In case it has been completed but not transmitted to HASHWallet, the transaction will be pending to link HASHWallet to the device.
- If an operation arrives to HASHWallet doesn’t return, it will retry for 1 minute and if no connectivity is available, it will be deleted.
Crypto assets and exchange management
HASHWallet supports the major cryptocurrencies, including the most widely used currencies such as Bitcoin, Ethereum, Litecoin and many others. Also, it is ready to hold any token based on the ERC-20 protocol.
If you don’t find the one you need, please contact us to request it.
HASHWallet allows multiple wallets from one single user account. It is not necessary to create different user accounts to use more than one wallet. It is possible to have as many wallets as needed for the same coin. Also, you can leave a wallet and transfer its funds to a new one with the same account and App.
No, there is no token related to HASHWallet project. Also, there are no plans to launch an ICO or IEO.
HASHWallet will provide the user with a complete suite of applications to manage the device and its crypto-assets, both on the Android and iOS mobile platforms and in desktop versions for PC, MacOS and Linux. These Apps are currently under development and are scheduled to be released in October 2020, prior to the delivery of the first smart cards.
Download the official application from Google Play or Apple Store and install it on your mobile device.
When you open it for the first time, it will ask you if you already have a HASHWallet. If you don’t have it, the App will enter in demo mode so you can take a look at its features and register in eSignus Vault. If you already have a HASHWallet, the App will look for your HASHWallet card through Bluetooth and detect it. You must follow the instructions to pair your mobile device with the card.
During this process, it will create your new user account, which requires a username and password to store (and retrieve if necessary) your Recovery Key. The process is identical whether the device is on a smartphone, a laptop or a desktop computer for user registration.
To register new devices, after linking the first one to your HASHWallet, you must allow the registration from the hardwallet to enable the connection to eSignus Vault.
No, you can work with HASHWallet without going through any KYC and AML check.
