Stablecoins have evolved from being payment tools in the cryptocurrency market to an important component of global fund transfers, savings, and yield management, yet they still face challenges such as regulation and reliance on the banking system.

Stablecoins account for two-thirds of on-chain transaction volume, whether for exchanges, DeFi trading, or simple transfer payments. Initially, stablecoins gained attention through Tether (the first widely used stablecoin). Tether was created to address the issue faced by Bitfinex users who could not easily use fiat currency due to banking restrictions. Bitfinex launched USDTether, promising to be 1:1 backed by the US dollar. Since then, Tether has spread rapidly, with traders using USDT for arbitrage across different trading platforms. Compared to traditional bank wire transfers that take days to complete, Tether transactions can be confirmed in just a few blocks (minutes), making USDT a highly advantageous payment tool in the crypto market.

However, although stablecoins were initially designed to solve specific problems in the cryptocurrency ecosystem, they have long surpassed their original purpose, becoming the core driver of everyday fund transfers and increasingly used for earning yields and facilitating real-world transactions. Currently, the total market capitalization of stablecoins accounts for about 5% of the cryptocurrency market, and when considering the companies managing these stablecoins or blockchain networks like Tron that primarily rely on stablecoin usage for valuation, the overall market share of stablecoins is nearing 8%.

Despite the rapid growth of stablecoins, there is relatively little content on why stablecoins are so popular. Tens of millions of users are replacing traditional financial systems with stablecoins, yet there is little understanding of the true driving factors behind this shift. Furthermore, research on the platforms and projects supporting the stablecoin ecosystem and the different user groups is scarce. Therefore, this article will delve into why stablecoins are so widespread, who the main players in the stablecoin space are, and which user groups are driving this trend, as well as analyze how stablecoins are gradually becoming the next stage in the evolution of money.

1. A Brief History of the Dollar

When you think of "money," what comes to mind? Cash? The dollar? Price tags in supermarkets? Or taxes? In these scenarios, money is essentially a conventional unit of measurement used to assess the value of various different and heterogeneous goods and services.

Initially, the form of money was shells and salt, which then evolved into copper coins, silver coins, and gold coins, leading to today's dollars/ fiat currency.

1) Let's Focus on the Dollar

The dollar (and modern fiat currency, which is issued by the government and not backed by physical assets) has gone through several stages of development. In the United States, the initial dollar bills (bank-issued paper currency) were private. At that time, banks could freely print money, a model somewhat similar to the Hong Kong dollar (HKD) system. However, due to numerous issues with this model, the government eventually intervened and took over the issuance of the dollar, legally tying it to gold.
In 1871, Western Union completed the first wire transfer using telegraph, achieving a breakthrough in fund transfers without the need to physically move large amounts of cash. This innovation greatly enhanced the efficiency of the financial system by eliminating the physical limitations of money circulation, making the entire financial system more efficient.

2) A Brief History of Dollar Development

• 1913: The Federal Reserve System was established, beginning to regulate the issuance of dollars and monetary policy.

• 1971: Nixon ended the gold standard, decoupling the dollar from gold and transitioning to a freely floating currency system.

• 1950: The first credit card was born, marking the beginning of the cashless payment era.

• 1973: The SWIFT (Society for Worldwide Interbank Financial Telecommunication) payment network was established, making dollar transactions faster and more globalized.

• 1983: The first digital bank account was established at the Stanford Federal Credit Union, initiating the digitalization of banking.

• 1999: PayPal was launched, enabling purely digital payments without a bank account.

• 2014: Tether launched the first dollar-backed stablecoin (USDT), laying the foundation for today's stablecoin market.
  All these developments have brought us to the current era of stablecoins.

  This brief historical review reveals an important fact: the form of money and the way we use money are constantly changing.

  Today, whether paying $20 through PayPal, cash, Zelle, or bank transfer, all are completely viable options (though using traditional bank transfers might earn you some strange looks). In developing countries, and increasingly in many developed countries, this trend also applies to stablecoins.

  Personally, I pay salaries with stablecoins, have exchanged cash for stablecoins, and now even prefer to use stablecoins instead of bank accounts for savings, utilizing protocols like @HyperliquidX's HLP, AAVE, Morpho, and @StreamDeFi to manage funds.

  The world we live in often places a heavy burden on the most vulnerable groups due to the traditional financial system. Capital controls, the monopoly of banks, and high fees have become the norm. In such an environment, stablecoins have become a powerful tool for financial freedom—not only making cross-border currency transfers more convenient but also gradually being used for direct payments for goods and services.

  To understand how stablecoins have achieved success in such a short time, we first need to clarify why stablecoins can outperform the traditional financial system.
   

  2. Stablecoins vs. Bank Transfers: A City, Two Stories

  
  The essence of stablecoins is that they are tokens backed by fiat currencies (such as the US dollar or the euro).

  Many readers of this article may come from developed countries in North America, Europe, or Asia, where the financial systems are relatively efficient, smooth, and stable. In the US, there are PayPal and Zelle, in Europe, there is SEPA, and in Asia, various fintech companies are emerging, with the most well-known being Alipay and WeChat Pay.

  In these regions, people are accustomed to depositing money in banks without worrying that their account balance will disappear the next day, nor do they have to fear hyperinflation. Small transfers can usually be completed quickly, and even large fund movements, while they may take longer, are not unbearable. Additionally, most businesses force customers to use local banking systems because it is considered safer and more convenient.

  However, the reality is starkly different in another part of the world.

  In Argentina, bank deposits have been forcibly appropriated by the government multiple times, and the local currency is one of the worst-performing currencies in history.

  In Nigeria, the official exchange rate and the black market rate are severely disconnected, making it extremely difficult to move funds in and out of the country—ironically, this also applies to Argentina.

  In the Middle East, bank accounts can be arbitrarily frozen by the government, causing many ordinary citizens (especially those without political connections) to hesitate to store most of their liquid assets in banks, opting for other means to hold their funds.

  Not only is there a risk in holding funds, but transferring money is often even more challenging. SWIFT (Society for Worldwide Interbank Financial Telecommunication) cross-border transfers are expensive and cumbersome, and in these countries, most people do not have bank accounts due to the aforementioned reasons.

  As for alternatives like Western Union, while they can facilitate cross-border remittances, they typically charge extremely high fees (you can check their fee calculator). Worse still, they often settle at the official exchange rate, which is usually much higher than the actual market rate, leading users to bear huge "invisible" costs.
  
  Stablecoins allow people to hold funds outside the local financial system because they are essentially globalized, relying on blockchain for transfers rather than local bank servers. This characteristic stems from their historical background—cryptocurrency exchanges faced challenges in opening bank accounts, handling large deposits and withdrawals, and transferring across trading platforms.

  One of the most notable cases is Japan. Due to the bureaucratic complexities and strict capital controls of the Japanese banking system, there has long been arbitrage space between global cryptocurrency prices and local prices in Japan.

In 2017, BN announced in its white paper that its trading platform would only support stablecoin-cryptocurrency trading pairs to accelerate settlement speed. This move directly drove market trading volume towards stablecoin trading pairs. In 2019, BN launched USDT perpetual contracts, allowing users to trade on margin using USDT instead of BTC, further solidifying the dominance of stablecoins. Today, stablecoins have become the recognized foundational asset in the cryptocurrency market, and this acceptance is gradually expanding to applications beyond cryptocurrency.

3. Stablecoins vs. Fintech: Speed, Innovation, and Solutions to Global Financial Issues

When we look at transaction speed, innovative design, and the ability to solve global financial problems, stablecoins and fintech (Fintech) have significant differences.

So far, the main contribution of fintech has been to optimize and beautify existing payment infrastructure rather than fundamentally changing its underlying architecture. Essentially, they merely add a layer of "coating" on top of the traditional financial system, without addressing its inherent inefficiencies and complexities. In contrast, stablecoins represent the most significant transformation in the global financial system in 50 years.

• Fast, reliable, and transparent: The transfer speed of stablecoins far exceeds that of traditional banking systems, while also providing on-chain verifiability, making fund circulation more efficient.

• Low-cost remittances: Compared to traditional payment methods like bank wire transfers or Western Union, stablecoins almost eliminate high fees (though this also means losing some protections offered by traditional financial systems).

• Competitors to cash and payment processors: Stablecoins can not only replace cash but also compete with payment processing institutions like Western Union, while being safer and more durable than cash.

• Not easily destroyed or stolen: Stablecoins do not disappear like cash due to floods, fires, or theft, and can be converted to local currency at any time.

• Extremely low transaction fees: The transfer cost of stablecoins depends on the blockchain network but is usually less than $2, and is a fixed fee, far lower than the fees of traditional payment systems like Western Union (which typically range from 0.65% to over 4%).
  All of this indicates that stablecoins not only dominate the cryptocurrency space but are also challenging the foundations of the traditional financial system.
  
  Once stablecoins are widely accepted and gradually mature, they will inevitably fill the gaps in the global financial system that traditional financial institutions have yet to cover. As stablecoins continue to gain popularity, the financial services and complex products surrounding them are also growing rapidly.

  For example, @MountainUSDM has introduced RWA (Real World Assets) yields on multiple platforms in Argentina, while @ethena_labs allows users to profit through delta-neutral trading without relying on traditional banking systems or trading platform custody.

  Today, the uses of stablecoins have far exceeded simple payment processing or hedging; more and more people are starting to use stablecoins to earn yields and even for local payments. As this trend develops, stablecoins are gradually becoming an important part of global financial planning, even being incorporated into corporate balance sheets.
  Notably, many stablecoin users may not even realize they are using cryptographic technology—this is a significant breakthrough in product innovation surrounding stablecoins in recent years. Major companies are continuously optimizing user experiences, making the use of stablecoins more seamless and intuitive, further driving their global adoption.

4. Companies Driving the Adoption of Stablecoins

The major stablecoin projects primarily consist of the companies issuing these stablecoins. These include:

• The issuer of USDC, @Circle
• The issuer of USDT, @Tether_to
• The issuer of DAI/USDS, @SkyEcosystem
• PYUSD, jointly launched by @PayPal and @Paxos. Of course, there are many other stablecoins not mentioned, but the above are the most significant stablecoins for payment purposes. These companies typically have bank accounts, receive traditional bank wire transfers, and convert these funds into stablecoins for users.

1) The Funding Operation Model of Stablecoins

Stablecoin issuers will hold the funds deposited by users and charge users very low fees (usually 1-10 basis points). Users can transfer these assets at any time, while issuers earn interest on the funds in their bank accounts (i.e., the "floating yield" or "yield" in the context of DeFi).

Trading companies play an important role in this process, responsible for large-scale processing of fiat and stablecoin conversions (on/off ramp). As more trading platforms begin to crack down on users who only use stablecoins for deposits and withdrawals without paying trading fees, the role of trading companies in this market becomes increasingly critical.

• Trading companies often offer better prices than local trading platforms, further enhancing the efficiency and competitiveness of stablecoins.
• As all major trading companies engage in fierce competition in this market, they continuously optimize liquidity and services, making stablecoin trading smoother.
• Stablecoin issuers earn interest in this process rather than charging users high fees, which is also the core of their business model.
  It is worth mentioning that @SkyEcosystem (formerly Maker) has a different model.
  • SkyEcosystem employs a hybrid model, with its stablecoin USDS backed by multiple collateral assets (including other currency reserves).
  • Users can deposit these collateral assets and borrow USDS at a predetermined interest rate.
  • They can choose to **deposit into a "savings rate module" (similar to a *risk-free rate)*, or borrow USDS on platforms like *@MorphoLabs, @Aave*, or simply *hold USDS*.
  • This model allows users to choose safer yield options or take on higher risks for higher returns.

2) User Growth of Stablecoins: Not Directly Consumer-Facing

Currently, most major stablecoin issuers do not directly target ordinary consumers, but rather provide stablecoin support indirectly through various financial service companies. This model is similar to MasterCard—it collaborates with banks but does not directly interface with end users.

You may rarely hear the names @LemonCash, @Bitso, @Buenbit, @Belo, @Rippio in the crypto community (CT), but they play important roles in the stablecoin trading market. For example:

• Just the few Argentine trading platforms mentioned above have over 20 million KYC certified users, nearly equivalent to half the user base of Coinbase, while Argentina's population is only 1/7 that of the United States.
• Lemon Cash had a trading volume of $5 billion in 2023, a significant portion of which was stablecoin-stablecoin trading or ARS (Argentine Peso)-stablecoin trading. These platforms serve as the entry point for most non-peer-to-peer stablecoin trading, and they themselves also have substantial crypto trading volume and stablecoin deposits. However, most platforms, except for Rippio, do not have their own order books, but rather rely on order routing systems to complete transactions.

This model is very similar to Robinhood—Robinhood is not a true trading platform but routes pricing through liquidity providers (Market Makers). I refer to these platforms as “Retail Venues” because their focus is on optimizing user experience and retail products, rather than building their own trading platform infrastructure.

• Robinhood's API does not allow high-frequency traders or market makers to use it, as its target users are not professional traders but ordinary investors.

• Similarly, BuenBit and Lemon do not attract market makers; their main target users are ordinary consumers, not professional trading firms or high-frequency traders. In this model, the application of stablecoins is entering the global financial system in a low-cost, high-efficiency manner, impacting not only the crypto market but also changing the landscape of traditional payments and remittances.
  
  Next, let's look at the blockchain where stablecoins actually operate, which is the place for stablecoin transfers, transaction records, and balance storage. Currently, the main chains for stablecoin trading include:

• @justinsuntron's @trondao (Tron)

• BN Smart Chain (BSC) from @binance

• @solana (Solana)

• @0xPolygon (Polygon). The main purpose of these chains is value transfer, and they do not necessarily involve DeFi interactions or yield generation.

  Although Ethereum still leads in TVL (Total Value Locked), it is not attractive for most stablecoin trading due to high transaction costs. Data shows:

• 92% of USDT transactions occur on the Tron chain.

• Approximately 96% of the transaction volume on the Tron network is related to stablecoins.

• In contrast, on Ethereum, stablecoin trading still accounts for a high proportion, but only 70%.
  Additionally, some new blockchains are trying to efficiently and cost-effectively handle stablecoin transactions, notably LaChain.

• LaChain is operated by an alliance of Ripio, Num Finance, SenseiNode, Cedalio, Buenbit, and FoxBit, primarily targeting users and platforms in the Latin American region.

• This also indicates that as the stablecoin market continues to mature, the ecosystem is becoming more complex and diversified.

5. The Evolution of Stablecoin Payments: From Cross-Border Remittances to Local Payments

Stablecoins have become the main tool for cross-border remittances, but today, they are increasingly being used for local payments.

This involves cryptocurrency payment gateways and payment portals, which:

• Convert stablecoins into fiat currency, or
• Allow merchants to directly accept stablecoin payments priced in fiat currency. For example, a merchant can “accept” crypto payments, but in reality, the cryptocurrency from this transaction will be immediately converted to USD and then settled into the merchant's bank account. Of course, merchants can also directly accept stablecoin payments.

However, due to the friction still present in redeeming stablecoins (whether in terms of time or fee costs), a large number of companies dedicated to optimizing this process have emerged, offering solutions ranging from simple and efficient to complex and comprehensive.

• Pomelo (https://www.pomelogroup.com/): A platform that supports cryptocurrency debit card payments, allowing users to spend directly with stablecoins.

• @zcabrams's Bridge: Provides convenient conversions between stablecoins, across different chains, and between fiat currencies, significantly reducing the friction costs for merchants and payment platforms.

  • @stripe even acquired Bridge to enhance the efficiency of its own payment system.
  • Currently, payment gateways like Bridge are mainly used in scenarios where merchants do not yet directly accept USDC or USDT; they first help users complete the conversion and then charge a fee.

  As stablecoin payments become more widespread, and given their lower costs compared to traditional bank cards and banking systems, the usage rate of stablecoin-stablecoin transactions will continue to rise. In the future, more and more merchants will directly accept stablecoin payments to optimize unit economics, driving stablecoins to build a payment system for a post-banking era.

6. The Financialization of Stablecoins: How to Make Stablecoins "Appreciate"

In addition to payments and remittances, more and more companies are exploring how to utilize stablecoins to enhance their asset utilization, such as:

• Lemon Cash: Offers @aave deposit features, allowing users to deposit funds to earn yields.
• @MountainUSDM's USDM: Allows stablecoin holders to earn yields and has been integrated into multiple trading platforms and payment services in Latin America.

Many trading platforms and retail financial platforms view stablecoin yield as a stable source of income, hoping to balance the income fluctuations caused by market cycles.

• Traditional trading platforms heavily rely on trading fees, which leads to a surge in income during bull markets, but a sharp drop in income by several orders of magnitude during bear markets.
• By offering stablecoin deposit yields and related services, these platforms can achieve more stable income, reducing the impact of market volatility on their profitability.

7. What is the Future Development of Stablecoins?

Non-Crypto Uses of Stablecoins: Expansion of International Transfers and Payments

The main non-crypto application of stablecoins is international transfers, and they are now increasingly used for payments. However, as the infrastructure for stablecoins continues to improve and gradually become widespread, they may also be used for savings, a trend that is already beginning to emerge, especially in developing countries.

A few weeks ago, @tarunchitra told me a story: In Georgia, a convenience store owner accepts deposits in Georgian Lari (GEL), converts them into USDT to earn interest, and keeps a simple paper ledger to record customer balances, taking a certain fee from the interest. In this store, customers can also pay using Trust Wallet's QR code. Notably, Georgia's banking system is relatively healthy, yet this alternative financial model is still developing here.

In Argentina, according to estimates from the Financial Times (FT), the total amount of cash in dollars held by citizens has exceeded $200 billion, and this money is outside the traditional financial system. **If even half of this money enters the on-chain or crypto ecosystem, the *DeFi* market size would double, and the total market capitalization of stablecoins would increase by about 50%**—and this is just the potential of one country. Similar situations exist in *China, Indonesia, Nigeria, South Africa, and India*, where there are *large informal economies or a certain level of distrust in the banking system*.

More Potential Use Cases for Stablecoins

As the use of stablecoins grows, their application scenarios are also continuously expanding.

• Credit Substitution: Currently, stablecoins are mainly used for fully collateralized credit substitution, a model that is extremely rare in the global credit market. However, with the launch of new tools by institutions like Coinbase, KYC certification data may be used in the future to expand the credit market and may introduce a negative credit record mechanism (i.e., failure to repay will affect credit scores).

• Yield Distribution: Stablecoin issuers are gradually allowing yields to be “passed” to holders, for example:

  • USDC offers an annualized yield of 4.7%
  • Ethena's USDe has a dynamic yield, usually exceeding 10%
     

• Cross-Fiat Transactions: Currently, many transactions are starting to adopt a “dual conversion” method— for example,

  • A transaction is first converted from the local currency to a dollar stablecoin, and then
  • converted to the target currency (such as Argentine pesos or Nigerian naira).
  • This practice means users need to pay fees twice, but as blockchain technology matures, it may be possible in the future to directly convert to stablecoins of the target currency to reduce costs.

As more capital flows into stablecoins, the variety of on-chain financial products will further enrich, making the application of cryptocurrencies in daily life more mainstream.

8. Challenges Facing Stablecoins

When discussing the future of stablecoins, we also need to face some overlooked issues.

1) Stablecoins Depend on the Banking System

• Currently, almost all stablecoins rely on bank accounts as their supporting assets.

• However, the banking system itself is not absolutely safe; for example:

  • In 2023, USDC briefly depegged due to the collapse of Silicon Valley Bank (SVB), indicating that even the most trusted stablecoins may face risks from the banking system.

2) Stablecoins are Widely Used to Evade Capital Controls and Money Laundering

• If you agree that stablecoins are used to bypass capital controls and escape local currency devaluation, you have effectively acknowledged a fact—that such behavior may be classified as money laundering under local legal frameworks.
• This is an open secret, but its legal and ethical implications have not been fully explored.

3) The Issue of Freezing and Inability to Reissue Stablecoins

• Currently, neither Circle (USDC) nor Tether (USDT) allows for the reissuance of stablecoins.
• If a user's funds are frozen for legal reasons (such as involvement in a crime or being deemed illicit funds), then these assets will not be returned to the victims, even if the latter holds court ruling documents.
• This handling is highly controversial on an ethical level and may even be difficult to sustain in the long term.

4) Government Regulatory Pressure & CBDC Replacement Risks

• Governments may require enhanced regulation of stablecoins, making them “seizable”.
• In the long run, Central Bank Digital Currencies (CBDCs) may become the official alternatives to stablecoins.
• This topic covers a wide range of issues, which I will explore in detail in future articles.

9. Truly Decentralized Stablecoins May Be the Solution for the Future

In the coming years, government regulatory pressure on stablecoins will drive the development of truly decentralized, privacy-preserving stablecoins.

• These stablecoins will not be able to be unilaterally frozen or seized by the government and will be completely decentralized.
• This may spark a new competition in financial technology, and the development of stablecoins may evolve from regulated financial instruments to truly decentralized currencies.
• Of course, this also means new compliance challenges.

Regarding the “dark side” of stablecoins, I plan to write more in-depth analytical articles in the future, as this is an extremely vast and far-reaching topic.
