Wallets

Whenever you are storing objects with a market value, security is necessary. This applies to barter systems as well as economies using currency as a medium of exchange. While banks store balances on a private ledger, cryptocurrencies store balances under unique addresses on a distributed public ledger. The cryptographic private keys to access the balance stored on each public address are therefore the object of value in this system. This section of the documentation discusses different practical methods of keeping these keys safe in wallets, while still remaining useful for day-to-day needs.

For safety, it is not recommended to store significant funds on exchanges or software wallets. If you are holding cryptocurrency worth more than the device you use to store it, you should purchase a hardware wallet.

NodeClient Wallet

SmartCash NodeClient Wallet is the full official release of SmartCash, and supports all SmartCash features as they are released, including InstantPay and SmartNodes, as well as an RPC console and Voting features. SmartCash NodeClient Wallet (sometimes known as the QT wallet, due to the QT software framework used in development) is a professional or heavy wallet which downloads the full blockchain (several GB in size) and can operate as both a full node or smartnode on the network. Because of the requirement to hold a full copy of the blockchain, some time is required for synchronisation when starting the wallet. Once this is done, the correct balances will be displayed and the functions in the wallet can be used. SmartCash NodeClient Wallet is available for macOS, Linux,and Windows.

Features:

• InstantPay
• Wallet encryption
• Coin control and fee control
• QR code generation and address book
• SmartRewards Monitoring
• SmartNode and SmartVote
• Automated backup
• Debug console

Electrum Wallet

SmartCash Electrum is a light wallet which uses powerful external servers to index the blockchain, while still securing the keys on your personal computer. Transactions are verified on the SmartCash blockchain using a technique called Secure Payment Verification (SPV), which only requires the block headers and not the full block. This means that wallet startup is almost instant, while still keeping your funds secure and mobile. It does not currently support advanced InstantPay features.

SmartCash Electrum is a fork of the Electrum wallet for Bitcoin. While this documentation focuses on using SmartCash Electrum, full documentation of all Bitcoin Electrum features (mostly identical in SmartCash Electrum) is available at the official documentation site.

FUTURE POTENTIAL OF SMARTCARD…

Debit and credit card payments have arguably become the dominant way for many to carry out most, if not all, of their daily transactions. Adoption of card payments became increasingly simple for smaller businesses, and now quick and affordable smartphone-powered solutions are already a reality. SmartCard emerged offering to solve many of the problems facing traditional systems. SmartCard is blockchain-based solution that aims to improve on the digital payment card model. Our main goals are to streamline crypto transactions and make them practical for use in real-life payment scenarios. At the same time, we aim to drastically reduce fees and confirmation time frames over those found in current solutions.

SOLVING MAJOR CHALLENGES WITH A SIMPLE SOLUTION

As they currently stand, both traditional cards and crypto payment solutions leave a lot to be desired. Transaction fees of over 3% for some cards can add up to substantial losses over time for businesses of all sizes. For even small businesses, it’s normal for more than $50,000 a year to be lost in processing fees.

In addition to this, both buyers and sellers must have access to major banks and their services in order to facilitate these types of transactions; a major problem in many parts of the world. Also, traditional services inherently have long confirmation times of up to several days, which can themselves lead to other issues. Cryptocurrencies have indeed proposed solutions to many of these challenges, as it is easy to find many projects today that offer instant transactions and virtually no fees. But, this doesn’t change the fact that using this new technology in its current form is like trying to send an email in the 80s – too time-consuming to setup and operate to be practical for most everyday applications.

Using their new feature called the SmartCard, the developers of SmartCash are looking to improve upon and/or eliminate entirely the present limitations of payment cards. SmartCard is the crypto alternative to the debit card which uses the SmartCash blockchain to easily initiate and verify transactions of any size and frequency. As with many other cryptocurrencies, the fees are right around 0%; it costs just fractions of a cent to process a transaction, regardless of the amount. The payments will be instantly confirmed at the time of purchase, meaning there is no delay between authorization of the payment and the transfer of the actual funds.

In a way, the purchases made with SmartCard combine the best of cash, card, and crypto payments. The funds are moved between parties instantly, like cash, but the transaction is authorized by the buyer with a simple code that can be either digitally stored on a smartphone or printed and carried separately as a physical QR code. This makes the payment process just as convenient as regular card payments, and far easier than having to send cryptocurrency manually from a mobile app.

HOW IT ALL WORKS

There are just two main applications: the card app for the consumer and the Point of Sale (PoS) app for the merchant.

The card app allows anyone to create a SmartCard with just a few taps. Each card has an associated public address which can be used to load more funds onto the card from any wallet or exchange that offers SmartCash. Also included into each one is a QR code which can be scanned by the PoS application from either a phone screen or from a simple piece of paper. Once loaded through this address, the card works very similar to a pre-paid debit card.

The PoS app is equally responsible for this convenience. The merchant only has to specify the transaction amount in the local currency, and the app automatically initiates a transaction in the equivalent amount of SmartCash. The merchant uses the app to scan the code and requests the buyer to enter a confirmation pin. After entering it on the merchant’s smartphone, the app connects to the blockchain to submit the transaction. If the code and pin match, and there are enough funds in the card address, the transaction is instantly verified and recorded on the blockchain. The process of scanning a card and entering a pin to confirm is already well familiar to current debit card users, and so it would be easy for everyone to get used to.

A REVOLUTIONARY PAYMENT SYSTEM EVERYONE CAN LOVE

This ease of use and familiarity present the key advantage of this system over other crypto payments, which require both parties to be online for a transaction. Once the card is created and loaded, only the merchant is responsible for having a live connection to the internet and the consumer can take the funds anywhere without worrying about a dead battery or lack of signal in remote areas. No need for fumbling with mobile wallet apps, nor any memorization beyond the simple numerical pin just like the ones used for debit purchases. In addition to this, it also offers the advantage of being usable in places where traditional banking services are only partially available, or even absent entirely. Whereas other mobile payment solutions require bank accounts for both parties to send/receive the funds, this one uses the SmartCash blockchain instead and is thus accessible to anyone who wishes to use it.

Naturally, these benefits would also be quite attractive to buyers and sellers in more developed nations as well. Other crypto solutions fall somewhat short of their promises. Crypto debit cards suffer from the same fees and transaction delays as any other current plastic card, and sending money through current mobile wallets requires a lot of time and effort to make the payments. Compared to these options, SmartCard payments are in a league of their own in convenience and speed. Add to this the fact that the SmartCash community is actively seeking, recruiting, and sponsoring business owners and entrepreneurs globally, and it is easy to imagine how the SmartCard could increasingly gain global adoption across a wide range of markets and economies.

Hardware Wallets

A hardware wallet is a type of device which stores private keys for a blockchain in a secure hardware device, instead of in a database file such as wallet.dat used with common software wallets. This offers major security advantages over software wallets, as well as practical benefits over paper wallets. To date, there is no verifiable evidence of hardware wallets being compromised by viruses, and they are also immune to keylogger attacks that could be used to steal passwords to unlock the private keys used with software wallets.

Hardware wallets function by storing your private keys in a protected area of a microcontroller. It is impossible for the private key to leave the device in plain text - only the signed output of the cryptographic hash is ever transmitted to the device interacting with the blockchain, such as your computer or smartphone. Most hardware wallets feature a screen which allows you to independently confirm the address you are sending to is correct.

This section lists the most common commercial hardware wallets supporting SmartCash, although some other enthusiast projects may also be available.
