Roman Makitrenko: How to find a balance between losses due to errors and quick implementation of functionality

Roman Makitrenko, Head of QA Wirex
Since Wirex works with our users’ money, the cost of an error is especially critical in this industry and can depend on many factors. At the same time, a bug in a fintech product can be assessed not only by the company’s costs of developing a solution to the problem. Mistakes can also result in loss of customer and reputation, and other losses to the company, depending on the priority and severity of the problems.

Therefore, there are a number of criteria that QA specialists need to consider when working with a fintech product:

• Safety . Fintech applications use and store sensitive data, including personal, financial and banking information. Please be aware that hackers may try to gain access to this information.
• Data protection . In the world of financial technology, information changes hands frequently, so protecting and managing important data is key during the product testing phase. Gaps in this area can lead to lawsuits and regulatory compliance issues, which can cause customers to lose trust in the company.
• Regulatory Compliance . Licensed FI organizations must adhere to a strict set of rules and regulations from the regulators of the countries in which they operate. These laws are constantly evolving, so functionality testing must change along with them. Compliance issues may limit certain financial transactions or block the app entirely in some countries or regions.
• Functional testing is an important step in any testing scenario. This process ensures that the product meets all necessary requirements to operate effectively. Because fintech product software involves the exchange of sensitive data and information, testers must examine all possible risks, events, stressors, and interactions with other applications and system components. If some functionality turns out to be unavailable or inactive, customers may choose a competitor's product, as a result of which the company may receive less profit from operating activities. It is also important to understand that problems with third-party services need to be resolved as if they were your own, since users will complain about your application regardless of which side the problems are on.
• UX : The quality of a product is based on how convenient and easy it is to use. The main priority of a fintech product is customer experience, and QA must ensure that the product is understandable and easy to use for non-experts. UX problems usually have a direct financial impact on the company, as the user may choose a competitor's app.
• Performance - It is important to ensure that the platform and services continue to operate during peak hours, regardless of load. Often these problems don't come alone and tend to be combined with UX problems.

When testing any cryptocurrency operation, we must always remember that the testing environment is not always the same as the production environment. So do third-party sandboxes and blockchain testnets. All these ecosystems are actively developing, and often the test environment has a more advanced version than the production itself, and sometimes vice versa. Therefore, everything that we tested in the sandbox must be double-checked in production.

Also, before you start testing, make sure that you know where to get test cryptocurrencies, since Bitcoin on the testnet and the mainnet are still two different currencies, with completely different properties and speed of operation.

Treatment reduces the risk of exacerbation of prostatitis, male strength returns, orgasm lasts longer.

The Virex complex is used for therapeutic or prophylactic purposes for diseases of the pelvic organs of infectious or non-infectious origin. Used in complex therapy of prostatitis and decreased erection.

How the drug works

Basic functionality of a cryptocurrency fintech application

Let's now take a closer look at the basic functionality of a fintech application using virtual currencies.

Once users have completed the registration and verification process, they are ready to use the product to its full potential. And to begin with, the client wants to know how many digital assets are in the application and what their exchange rate is.

But before the user can use this functionality, he needs to create a cryptocurrency account . For some blockchain platforms, this operation requires payment of a fee on the blockchain. In such cases, the company bears the costs and divides this operation into creating an account in the system and activating the account in the form of a blockchain address for a specific currency.

Of course, the user will need money to use the application. This could be a Welcome bonus or any other method that provides a replenishment of the balance in the system .

In order for users to make money on the difference in exchange rates of digital assets, it is necessary to provide the ability to exchange cryptocurrency in the application , as well as transfer digital currencies outside the system.

Let's look at each of these functionalities in more detail.

Characteristics and composition

Virex cannot be bought in a pharmacy because it is sold online, officially on the manufacturer’s website. The drug is produced in the form of a blister with white capsules. The effect of the medicine occurs due to its components, which made it possible to create a formula to combat impaired potency:

1. Sage – contains a number of tannins, flavonoids, amino acids, and alkaloids. It has a positive effect on the pelvic organs, relieves inflammation, suppresses pathogenic viruses and bacteria, and improves the functioning of the reproductive system.
2. Beaver stream is a secretion from the glands with a proven effect. It is widely used for the treatment and prevention of impotence, normalizes hormonal levels, makes sex bright, improves metabolic processes, and relieves spasms of smooth muscles.
3. Lovage - the root of the plant is rich in carbohydrates, vitamins, and minerals. Contains tannins and furocoumarins. The extract increases physical activity, normalizes brain function, and protects against infections.
4. Cordyceps is a source of vitamins and minerals, contains polysaccharides and adenosine. The component improves immunity, improves the functioning of the heart and blood vessels, and removes poisons and toxic substances from the body.
5. Elecampane – contains essential oils, saponins, and is rich in inulin. Anti-inflammatory, diuretic effect, reduces the risk of developing prostatitis, prostate adenoma. The components complement each other and can solve a number of problems with men's health.

The product contains no chemicals. With long-term use it does not cause addiction or side effects.

Victor, 47 years old Problems with erection appeared after suffering from prostatitis. I took medications and vitamins, but saw no results. I learned about the drug Virex on the forum and ordered it on the manufacturer’s website. I drank for a month, but the effect appeared within a week: potency increased, the penis really got stronger, discomfort in the lower abdomen disappeared, sex improved. I'm happy with the strength of the riser and there are no side effects! I used to take Viagra and Cialis, but they have a lot of contraindications and literally work for a couple of hours.

Wirex Account Security

For increased security, the service offers to set up two-factor authentication.

To activate it, you need to go to settings and move the slider to the right in the corresponding line.

Next, you will need to download an authentication application to your smartphone. Wirex offers two options – Google Authenticator or Authy.

The service will generate a unique QR code, which must be read through one of the authenticators.

A temporary code will appear in the application, which must be entered on wirexapp.

Now, every time you log into your account, the authenticator will create a random temporary code, which you will have to enter in the appropriate field.

Clinical researches

The effect of the formula has been proven by official testing, the results of which showed that proper use of the product will restore sexual function, increase libido and the quality of sexual life. The studies involved 486 men who experienced erection difficulties. They took the medicine regularly for a month.

After completing the course, the following results were recorded:

• 97% - increased potency, improved libido;
• 93% experienced an orgasm stronger than usual;
• 86% received a stable erection.

The drug passed a series of tests that showed:

• complex effect: eliminated problems with potency, increased desire;
• The course of treatment made it possible to control ejaculation and increase the duration of sex;
• In patients with prostatitis, inflammation decreased and symptoms disappeared.

The results of clinical studies have shown that Virex has a positive effect not only on sexual functions, but also on the body. Those who took it note that thanks to the drug they got rid of complexes and fear of failure during intimacy. It’s not difficult to order a natural product on the developer’s website - fill out the form, the store manager will contact you in 17 minutes.

During clinical trials, no negative effects on the body were recorded, which proves complete safety.

Withdrawing money outside the system

In this case the flow is as follows:

• The client selects the currency to send.
• Enter the value - the transfer amount.
• Confirms the transaction.
• The system publishes the transaction on the blockchain.

What is happening on the backend at this time?

The system checks the balance on the user's account. The system then calculates the commission. We remember that every transaction on the blockchain must be confirmed by miners. This means that such transfers require a commission for miners.

After sending the transfer, it is necessary to perform a credit operation and update balances in all services in the system. When checking the balance, we must ensure that users have enough money in their balance to cover the amount entered and the blockchain fee.

When withdrawing money outside the system, you need to check the existing limits.

Changing the cost of the commission when withdrawing money outside the system . Blockchain fees vary depending on the load on the blockchain - the higher the load, the more transactions are in the queue for confirmation. Therefore, in order for the client’s transaction to be confirmed faster, it is necessary to pay a higher commission to the miners. You should also consider these changes when testing your product.

Doctors' opinion

Positive reviews about the drug are left by doctors who have studied the complex. They claim that it truly works, copes with disorders in the pelvic organs, and makes orgasm brighter. Prescribed as a therapeutic or prophylactic agent.

Virex has received the approval of the Association of Urologists, has the necessary quality certificates, and meets the requirements of the EAC and GOST.

Sometimes there is a negative response about the medicine from doctors; they are skeptical about new products. But such reviews are not written often, since Virex contains components whose effects have been confirmed by official medicine.

Konstantin Nikolaev, sexologist Decreased erection is common among adult men, but not everyone rushes to the doctor and starts buying various potency stimulants. They do not eliminate the causes, but at the same time they have many side effects. In such situations, it is recommended to take Virex capsules. It treats all stages of prostatitis, helps solve decreased potency.

Valentin Markov, urologist Impotence begins after 35 years, and it needs to be treated comprehensively. Taking Viagra or other stimulants cannot cure the disease, only improve it for a short time. And with the natural drug Virex, everyone can have sex. The natural composition has a complex effect on the body, helps to obtain vivid emotions, restore the hardness of the penis, improve the functioning of the pelvic organs, and protect against prostatitis. I recommend using it for the treatment and prevention of impotence, and you can order the stimulator on the manufacturer’s website.

Alexander Penkov, urologist Erectile dysfunction in men occurs due to an incorrect lifestyle or as a result of internal pathologies. To get rid of weakness, it is important to determine the root cause. I have heard about Virex several times. Having studied quality certificates and clinical studies, I am confident that the stimulant can solve male problems, but it should be taken in courses in the initial stages of the disease or as a preventive measure. The components of the capsules will restore potency, relieve mental and physical fatigue, and improve the immune system. After completing the course, hormonal levels and reproductive functions improve, but before taking the product it is recommended to undergo a comprehensive study and consult a doctor. By using a stimulant, you can actually get rid of impotence and restore male strength. Using a natural complex, the treatment will bring quick results.

Reviews of the medicine are also left by men who have personally experienced the effects of taking it. They meet on our portal and forums where they discuss impotence.

Bitcoin in your pocket: startup Wirex wants to accustom the world to cryptocurrency debit cards

The founders of the London-based Wirex project, Russians Pavel Matveev and Dmitry Lazarichev, decided three years ago that cryptocurrencies (including the sensational Bitcoin) would be of interest not only to geeks, but also to a wide audience. Today, the number of daily transactions with Bitcoin has passed the 500,000 mark, and entrepreneurs, having decided in time to make Bitcoins understandable to ordinary people, are now selling a Wirex debit card (the number of cards issued exceeds 150,000), which can be used to pay in euros, dollars and pounds sterling and Bitcoins - where Visa and MasterCard are accepted. Services related to blockchain and bitcoins still remain a niche market, but in the future the technology and use of cryptocurrencies can become truly widespread, the creators of Wirex are sure.

Matveev worked for more than ten years as an independent consultant at Morgan Stanley, BNP Paribas, Societe Generale and Credit Suisse. With a diploma in computer science (a graduate of the Vologda Polytechnic Institute), he worked mainly on trading platforms and robots. Matveev also worked a lot with currency trading, so he learned about Bitcoin back in 2012. There was no interest in buying them for speculation; the new currency aroused more curiosity from a technological point of view. When Matveev tried to purchase the first bitcoins, he realized that it was not easy - he had to install software on the computer, think about sufficient power, so even the “techie” found all the nuances difficult. And the demand for cryptocurrency grew: the first stories about successful investments in Bitcoin began to spread on the Internet, the rate was steadily rising. More and more people stopped considering Bitcoin “outlaw”. Matveev thought about a service where it would be possible to work with cryptocurrencies in a simple interface and with an understandable product. Soon, in one of the London pubs, he was already discussing the idea of ​​a new startup with an old acquaintance, Dmitry Lazarichev. The entrepreneurs met in Moscow, at English courses. They then moved to London almost simultaneously. While Pavel was working in investment banking, Lazarichev began studying at Cass Business School, where he met the third co-founder, Georgy Sokolov (he invested about $30,000 at the start).

Lazarichev and Matveev discussed a debit card linked to a Bitcoin wallet. “At that time, there were already services that simplified the process of buying bitcoins, but there was still practically nowhere to spend them,” recalls Lazarichev. “People usually trust both the banking system and credit cards,” adds Matveev. “And we decided to combine this - cryptocurrencies, in particular Bitcoin, and cards.” Now at the startup’s office in the City of London, visitors are greeted by a sign: “Spend bitcoin anywhere.” During the first year of development, the three founders, including funds from acquaintances and friends, invested about $300,000. Money was needed not only to create IT products, but also to ensure card processing and build partnerships with payment providers.

Advertising on Forbes

At first, Matveev, Lazarichev and Sokolov created the Ecoin platform, where it was possible to convert fiat and cryptocurrencies; six months after the launch, the startup began issuing virtual and physical debit cards. Finding a bank that would issue cards and cooperate with Visa or Mastercard took longer than planned. “Three years ago, and, frankly, still, when people hear the word “bitcoin,” they imagine buying drugs or paying a ransom from some blackmailers,” says Matveev. — When we tried to open even an ordinary bank account, they told us: “You are a Bitcoin startup, we will not work with you. What can we say about finding a banking partner.” Entrepreneurs wrote letters to banks all over the world, and only in this way, by “selection,” were they able to get banking partners to work in 130 countries. To create fiat accounts and issue cards, a partnership was concluded with the payment company Wave Crest Holdings Limited and with the Japanese holding SBI (also became an investor in the startup; today it became known that they raised $3 million). But banks, for example, in India and the USA could not be convinced.

At the beginning of 2016, when Ecoin already had more than 100,000 users, Matveev, Lazarichev and Sokolov decided to rebrand and launch a new product called Wirex. The money for its creation (more than €150,000) was received on the BnkToTheFuture site - a crowdfunding platform like KickStarter, only exclusively for blockchain projects. Since the “investors” (about 90 people supported the project in total) of BnkToTheFuture were well acquainted with blockchain technology and cryptocurrencies, the idea of ​​Matveev, Lazarichev and Sokolov quickly found a response: they managed to raise about €40,000 more than planned.

The idea of ​​Wirex involved not just issuing debit cards with bitcoins, but a “personal bank” in which users could transfer money from one continent to another and convert a variety of currencies – both fiat and cryptocurrencies. The idea is that if you use Bitcoin as an “intermediate” currency when converting dollars to euros, the exchange rate may be better. In calculations, the Bitcoin rate (since it does not have an official rate set by central banks) is determined on an internal exchange, usually based on data from several Bitcoin exchanges and the XBX Bitcoin Index, one of the main Bitcoin indices since late 2014. Transactions are carried out using a third-party instant payment service between Bitcoin wallets, BitGo Instant.

In February 2016, entrepreneurs released a virtual card application for iOS and Android and began sending plastic cards to residents around the world. In the application, you can make domestic and international transfers (costing about 1¢ - this is usually a commission to the miner), pay for purchases on the Internet and at offline points - wherever Visa and Mastercard work. Wirex also supports NFC payments from a mobile phone. Accounts are replenished either through cash at ATMs, or through bank transfers, or from wallets with cryptocurrencies (in the beginning there was only Bitcoin, then, with a connection to the Shapeshift exchange, Wirex began to convert any others - Litecoin, Voxels, Ethereum, etc.). The mobile application contains an analysis of expenses and recommendations based on the user’s financial activities and, for example, you can split the cost of a gift or check in a restaurant between several people.

However, Matveev asks not to put Wirex on a par with neobanks (banks that operate via the Internet, usually without any offices). “Millennials carry their smartphones, they are more internet-savvy than previous generations, they don’t like going to branches, and they don’t need face-to-face interactions with consultants at all,” says the entrepreneur. Millennials, earning more money than others, are becoming the dominant segment of the mass audience, which is why we see so many neobanks, Matveev explains. But Wirex is not banking 2.0, but 3.0, he emphasizes: the new era of banking will be based on multi-infrastructure applications, allowing the user to combine traditional and blockchain ecosystems in everyday life.

The startup takes money from clients' monthly account maintenance fees, domestic and international ATM transactions, and transfer fees. The tariff schedule is based on the cost of services for Wirex Visa and Mastercard, as well as partner banks. On top of these amounts, Wirex adds its own markup (the founders do not disclose its size). The startup's monthly revenue is about $250,000.

Today Wirex has more than 500,000 accounts, the total amount of transfers every month exceeds $15 million, the total amount of deposits is $5 million. Most of the startup's clients are in Europe and Southeast Asia. Accounts in cryptocurrencies have proven to be in demand as an alternative investment instrument. For some users (for example, in Venezuela and Ukraine), it turned out to be attractive due to the unstable local currency. For others (eg in the UK) it is due to low interest rates on savings accounts at regular banks. And in Japan, Wirex customers preferred a Bitcoin debit card to regular deposits and bank cards, as they did not want to lose money due to deflation. For part of Wirex's audience, a single mobile account is important for international payments and fast currency conversion. Among the startup's users, for example, is the owner of a small surf school in the Canaries. All his clients are foreigners, they pay in different currencies, and now they can also pay with bitcoins. Freelancers are also often issued a Wirex card to receive payment for their work. It is very convenient for programmers, designers or copywriters to accept payments in bitcoins - it is fast, and the transfer amount can be accurate to a fraction of a cent (digital currencies also provide the possibility of microtransactions). With Bitcoin, for example, you can receive payment for completed work several times a day, and the transaction status is always publicly available.

Some of the freelancers working with Wirex are involved in the development of blockchain projects and are paid in Bitcoin. “Traditional financial products solve the problem locally perfectly – you can go to almost any store and pay with a card,” says Lazarichev. “When there is a need for international transfers, transactions via blockchain are much faster and more efficient.”

SBI’s money is needed to make the service, still known among blockchain enthusiasts, widespread. The startup’s plan is to issue 1 million plastic cards and, possibly, the same number of virtual cards during 2017. Today, Wirex is already developing educational programs so that freelancers and remote workers, as well as those who transfer money to their relatives and friends living abroad, become the main audience of the service (so far less than half of them). For example, it will soon be possible to top up Wirex cards using any other debit and credit cards. In particular, the startup is working on a full-fledged bank statement for blockchain transactions. Contactless Bitcoin payments from smartphones (“cryptocurrency PayPass”) will appear, Matveev promises. In addition, the founders of the startup expect to expand the capabilities of accounts in cryptocurrencies: just as today money in accounts in regular banks can serve as a source for investments, for example, in securities or funds, or go to secure loans - funds in cryptocurrencies also, with the consent of their owner, can work using the same mechanics.

Wirex plans for 2022 include expansion into the United States and China (in China they will establish a partnership with UnionPay, which often replaces Visa and Mastercard, and conversion into yuan, Japanese yen and Canadian dollar will appear). So far, only about 5% of Wirex’s audience is from Russia and the CIS countries - there are cheap transfers within the country, explains Matveev. The service's audience will grow by at least 10% monthly, adds Lazarichev.

Cards are just one of the service areas that banks will enter as soon as cryptocurrencies become widespread, says Mikhail Lobanov, managing partner of Target Global. In his opinion, the game is not worth the candle: while the audience of such services is limited to “geeks”, large banks do not contact this market - they are deterred by increased risks in the field of compliance and regulation, and the costs of releasing and servicing a new product are higher. And this is for the sake of a small audience of users who, moreover, withdraw only a few thousand dollars from the ordered card (which can be created without identification) and never use it again. This is why, Lobanov explains, companies like Wirex charge fees for issuing cards. Ordinary banks do not charge any fee for this from the client, counting on a different format for using the card - the client remains with the bank for several years, makes transactions using the card, and the bank makes money on fees for transactions and on additional services. “As soon as the use of cryptocurrencies becomes widespread, banks will come to this segment and reduce commissions so that individual companies will have a hard time,” Lobanov sums up.

In addition, if at the start in 2013 Wirex had only one major competitor - the Xapo service, financed for $40 million, with coverage in China, Japan, Canada and the UK - now Matveev, Lazarichev and Sokolov will have to bypass about a dozen more companies . Their tariff schedule and set of options are almost the same, so the only way to get ahead is through new services. In addition, there are convenient mobile applications with connected multi-currency bank cards without cryptocurrencies: for example, another British startup with Russian roots, Revolut, has more than 500,000 users and a total amount of venture investments of $4.8 million.

Cryptocurrencies still remain in a gray zone, notes Alexander Lazarev, partner at Maxfield Capital. “Much of the Bitcoin transaction volume comes from countries with a high share of the shadow economy, and because of this, cryptocurrency cards are under regulatory pressure,” he says. This is a serious blow to competitive advantages (such products actually outperform conventional multicurrency cards in transfers and conversions in terms of speed and cost). Another problem is that it takes time for providers to complete a transaction in Bitcoin. Therefore, to ensure instant exchange on the client side, they need to reserve significant working capital in their accounts.

However, Matveev, Lazarichev and Sokolov are optimistic. “Some competitors have a conventional card infrastructure, good design and are well suited for individual user problems,” explains Lazarichev. “Other competitors rely only on blockchain and cryptocurrencies, but do not use the developments created in ordinary fintech at all.” Entrepreneurs expect that by “building bridges” they will be able to occupy a place in a new major niche.

How to buy a stimulant on the manufacturer’s website

As an official supplier, we offer to order and buy the drug on the company’s page in Russia without overpayments, and receive a certified product. All you have to do is request a call back by filling out the form. A manager will contact the buyer for consultation and answer any questions.

Alexander, 50 years old, a doctor friend advised me to buy Virex as a preventive medicine for diseases of the pelvic organs. I took 1 piece a day for a month. I can say with confidence that the drug works, increases potency, makes orgasm bright, and sex lasts.

Rounding the amount

One of the most common cases to check in a fintech product, especially one that works with cryptocurrencies, is difficulties with rounding, long numbers, and many signs after “,” in decimal values. For example, a user sends 1.999998 into the system, but as a result of rounding/type conversion, is able to send 1.999999 out of the system.

Cryptocurrencies, unlike traditional ones, have high accuracy; the response of a crypto exchange can look like 8, and sometimes 15 decimal places. For some currencies it can be significantly higher. Please be aware that automatic calculations can be erroneous, and it is best to fully test libraries that perform calculations with such figures. We also know that rounding is present throughout the system and needs to be checked. Some operations will be rounded to the nearest value within the specified precision, others will be rounded up or down as required.
