Stablecoins now account for up to two-thirds of all blockchain transaction volume. They are widely used for trading, decentralized finance (DeFi) applications, and daily fund transfers. The popularity of stablecoins began with Tether (USDT)—the first widely adopted stablecoin. Tether emerged as a solution for Bitfinex users who faced restrictions with traditional banking channels. To address this, Bitfinex created USDT, promising that each token would be backed 1:1 by US dollar reserves. USDT quickly gained traction as traders discovered it enabled efficient arbitrage across exchanges—transactions took minutes instead of days via bank wire.
Over time, stablecoin applications expanded far beyond cryptocurrency. Today, they serve as vital tools for cross-border payments, yield farming, and real-world transactions. Stablecoins currently represent about 5% of the total cryptocurrency market capitalization. When accounting for companies managing stablecoins and blockchains that rely on them (like Tron), this share rises to 8%.
Despite rapid growth, the reasons behind their widespread adoption remain underexplored. This article examines why stablecoins have become popular, identifies key market players, and highlights the user groups driving their expansion.
A Brief History of Money
What comes to mind when you think of "money"? Cash? Dollars? Prices in a supermarket? Taxes? In each case, money serves as a universal unit of account, measuring diverse and heterogeneous goods. Money has taken many forms throughout history—shells, salt, copper, silver, gold, and now, government-issued fiat currencies like the US dollar.
Modern fiat money evolved through several stages. In the US, early banknotes were privately issued. Banks could print their own currency, a system somewhat similar to today’s Hong Kong dollar (HKD). Eventually, the government intervened, centralizing the monetary system and backing the dollar with gold.
Key milestones in monetary evolution:
- 1871: Western Union executed the first wire transfer, eliminating the need to physically transport money.
- 1913: The Federal Reserve System was established.
- 1971: President Nixon ended the gold standard, making the dollar a free-floating currency.
- 1973: The SWIFT network launched, accelerating global dollar transactions.
- 1999: PayPal introduced digital payments without requiring bank accounts.
- 2014: Tether launched the first dollar-backed stablecoin.
This history shows that money and its uses are constantly evolving. Today, sending $20 can be done via PayPal, Cash App, Zelle, or bank transfer—though the latter is increasingly seen as outdated. In many developing and developed nations, stablecoins are filling similar roles. Personally, I use stablecoins to pay salaries, exchange for cash, and store savings instead of relying on traditional banks. I also use protocols like Hyperliquid’s HLP, AAVE, Morpho, and Stream Finance for yield generation.
We live in a world where the financial system often burdens the most vulnerable. Capital controls, monopolistic banking, and high transaction fees are commonplace. Stablecoins represent a transformative tool, enabling global value transfer and direct payment for goods and services. To understand this shift, we must examine how stablecoins outperform traditional finance.
Stablecoins vs. Bank Transfers: A Comparative Analysis
Stablecoins are tokens backed by fiat currencies like the US dollar or euro. Many readers from North America, Europe, or Asia may be accustomed to efficient financial systems. The US has PayPal and Zelle; Europe has SEPA; Asia has Alipay and WeChat Pay. In these regions, people trust banks with their deposits, and small transfers are often instant.
However, this isn’t the reality for much of the world. In Argentina, bank deposits have been confiscated by the government, and the peso is one of the worst-performing currencies in history. In Nigeria, official exchange rates differ vastly from market rates, moving money in or out is extremely difficult. In the Middle East, bank accounts can be frozen arbitrarily, discouraging liquidity storage in banks. Not only is saving risky, but remittances are also costly. SWIFT transfers are expensive and slow, and many people lack access to bank accounts. Alternatives like Western Union charge high fees (often 0.65%–4% or more) and use unfavorable official exchange rates.
Stablecoins allow users to bypass local financial systems. They are global by design, transferring value via blockchain instead of relying on banks. This development is rooted in history—early crypto exchanges struggled to secure banking services, making deposits, withdrawals, and settlements challenging. In 2017, Binance announced it would only support stablecoin-crypto trading pairs for faster settlement. By 2019, Binance launched USDT perpetual contracts, cementing stablecoins’ role in crypto markets.
Comparing stablecoins to fintech reveals critical differences in speed, innovation, and problem-solving. Fintech firms often optimize existing payment interfaces without changing underlying infrastructure. Stablecoins represent the most significant transformation in global finance in 50 years. They offer fast, reliable, verifiable transfers ideal for value storage and cross-border remittances—without high bank fees (though they sacrifice some protections).
Stablecoins compete with cash and services like Western Union but are more secure and durable. They can’t be washed away in floods or stolen in burglaries and are easily exchanged for local currency. Transaction fees (depending on the blockchain) are often under $2, compared to traditional services that charge percentage-based fees and hidden costs.
As stablecoins gain adoption, they fill gaps in the global financial system, especially where traditional institutions fall short. New services and products are emerging:
- Mountain USDM brings real-world asset (RWA) yield to platforms in Argentina.
- Ethena Labs lets users earn yield via delta-neutral strategies without relying on banks or custodial exchanges.
Today, stablecoins are used not only for payments and storage but also for earning yield and handling local transactions. They are becoming part of global financial planning and corporate balance sheets. Many users don’t even realize they’re using cryptocurrency—a testament to the maturity of stablecoin products.
Key Players Driving Stablecoin Adoption
Major stablecoin issuers include:
- Circle (issuer of USDC)
- Tether (issuer of USDT)
- Sky Ecosystem (issuer of DAI/USDS)
- PayPal and Paxos (issuers of PYUSD)
These are among the most widely used payment stablecoins. These companies hold bank accounts, accept traditional transfers, and convert funds into stablecoins. They charge low fees (typically 1–10 basis points) and earn interest on deposited reserves—similar to "float income" in DeFi.
As exchanges limit direct fiat-to-stablecoin conversions, trading firms have become key players in large-scale conversions. They offer better pricing than local exchanges, improving liquidity and efficiency. Sky Ecosystem (formerly Maker) employs a hybrid model:
- Its stablecoin, USDS, is backed by multiple collateral types.
- Users can deposit assets and borrow SUSDS at predetermined rates.
- Options include low-risk savings (near risk-free rates) or higher-risk lending on platforms like Morpho and Aave.
Most major issuers don’t interact directly with consumers but work through intermediaries. This resembles Mastercard’s model—serving users via banks rather than directly. For example, Lemon Cash, Bitso, Buenbit, Belo, and Rippio are less known in Crypto Twitter but have substantial influence. These Argentine platforms alone have over 20 million KYC’d users—half of Coinbase’s user base, despite Argentina having one-seventh the population of the US. In 2023, Lemon Cash processed around $5 billion in volume, mostly stablecoin-to-stablecoin or peso-to-stablecoin conversions.
Platforms like Lemon act as bridges for non-P2P stablecoin transactions, forming critical infrastructure. They focus on retail user experience rather than building trading infrastructure—similar to Robinhood, which routes orders to market makers rather than maintaining its own exchange.
Blockchains facilitating stablecoin transfers include Tron, Binance Smart Chain (BSC), Solana, and Polygon. These networks enable value transfer between users, though not necessarily for DeFi interaction or yield earning. While Ethereum leads in total value locked (TVL), high transaction costs have driven most stablecoin transfers elsewhere. Data shows:
- 92% of USDT transactions occur on Tron.
- 96% of Tron transactions involve stablecoins.
- Ethereum’s share of stablecoin transactions is 70%—significant but lower than Tron’s.
New, efficient blockchains are emerging optimized for stablecoin transactions. LaChain, a consortium chain by Ripio, Num Finance, SenseiNode, Cedalio, Buenbit, and FoxBit, serves Latin American users and platforms. These trends indicate a maturing, diversifying ecosystem.
As stablecoins gain use in cross-border remittances, they’re increasingly applied to local payments. This has spurred new infrastructure—crypto payment gateways that convert stablecoins to fiat or enable stablecoin-denominated payments. For example, a merchant might accept crypto but instantly convert it to dollars deposited in a bank. Alternatively, they might hold stablecoins directly.
Since converting stablecoins to fiat involves friction (e.g., delays or fees), companies are streamlining the process. Solutions range from simple products like Pomelo (which offers crypto debit cards) to complex systems like Bridge (acquired by Stripe), which facilitates conversions between stablecoins, blockchains, and local currencies.
As more merchants accept stablecoins to reduce costs (compared to cards or bank transfers), stablecoin-to-stablecoin transactions and direct payments will grow. This could lead to a post-banking payment world.
Companies are also focusing on helping users earn yield on stablecoins. Lemon Cash lets users deposit funds into Aave to earn interest. Mountain USDM, integrated into several Latin American retail platforms, offers yield-bearing stablecoins. For platforms, yield services provide stable revenue, reducing reliance on transaction fees that fluctuate with market conditions.

The Future of Stablecoins
Stablecoins’ primary non-crypto use is international transfers, but they’re increasingly used for payments. As infrastructure improves, applications will broaden, and savings could flow into crypto—especially in developing countries. Weeks ago, I heard a story from Georgia: a shop owner accepts lari deposits, converts them to USDT, earns yield, and records balances in a handwritten ledger. The same shop accepts payments via Trust Wallet QR codes. Notably, this occurs in a country with a relatively healthy banking system.
In Argentina, an estimated $200 billion in US cash is held outside the financial system. If half of that entered blockchain, DeFi would double, and the global stablecoin market cap would grow by 50%. Argentina is just one example; China, Indonesia, Nigeria, South Africa, and India have vast informal economies or distrust in banking systems.
As stablecoin usage grows, additional applications may emerge. Currently, stablecoins are used for "fully collateralized credit," rare in global finance. However, new tools from companies like Coinbase could use KYC data to extend credit, with non-payment affecting credit scores. issuers are also increasingly passing yield directly to holders—USDC offers 4.7% APY, while Ethena’s USDe often yields over 10%.
Cross-currency transactions are another growing trend: a transaction starts in one currency, converts to a dollar stablecoin, then to a third currency. If this continues, executing directly on-chain will be more efficient, avoiding double conversion fees. As more funds flow into stablecoins, on-chain financial products will diversify, accelerating mainstream adoption.
Future Challenges
Despite promise, stablecoins face unresolved issues. Almost all existing stablecoins rely on banks to some degree. The 2023 USDC depeg and Silicon Valley Bank collapse showed that the banking system isn’t foolproof.
Additionally, stablecoins are widely used for money laundering. If you agree they help users evade capital controls or escape currency devaluation, you acknowledge this use may be illegal under local laws. This is an open secret with profound implications. Currently, neither Circle nor Tether allows stablecoin reissuance. If funds are frozen due to legal action or being deemed stolen, they can’t be returned to rightful owners—even with a court order. This mechanism is morally questionable and likely unsustainable.
Governments will increasingly demand compliance, making stablecoins subject to seizure. In extreme cases, this could lead to replacement by central bank digital currencies (CBDCs). However, regulatory pressure may also create opportunities for truly decentralized, privacy-focused stablecoins operating beyond government reach.
