Stablecoins have evolved from niche crypto experiments to pivotal tools in the global financial ecosystem. Initially designed to offer price stability by pegging to fiat currencies like the U.S. dollar, they are now unlocking transformative use cases—especially in cross-border payments, tokenized real-world assets (RWA), and integration with artificial intelligence (AI) agents. As regulatory frameworks take shape in key markets such as the U.S. and Hong Kong, stablecoins are poised for accelerated adoption across mainstream finance.
This article explores how stablecoins are redefining payment infrastructure, why competition among different stablecoin variants remains fierce despite their shared value pegs, and how emerging applications like tokenized equities and AI-driven transactions are set to reshape financial liquidity on a global scale.

Stablecoins vs. Traditional Finance: A New Paradigm in Payments
The Efficiency Edge of Blockchain-Based Transfers
Stablecoins operate on decentralized blockchain networks, enabling peer-to-peer transfers without reliance on centralized financial intermediaries. Unlike traditional banking systems—where users depend on institutions to maintain account records, process transactions, and enforce compliance—stablecoin users retain full control over their digital wallets.
One of the most significant advantages is payment finality. With stablecoins, transactions are settled instantly upon network confirmation, a concept known as payment-as-settlement. In contrast, traditional international wire transfers can take days due to intermediary banks, currency conversion layers, and compliance checks. Even stock trades require T+1 or T+2 settlement periods.
Moreover, opening a bank account often involves extensive documentation, credit checks, and geographic limitations—barriers that exclude nearly 1.4 billion unbanked adults worldwide. Blockchain-based stablecoin accounts, however, only require internet access and a smartphone. This lightweight onboarding enables financial inclusion in underserved regions, particularly where local currencies suffer from hyperinflation.
For example, in parts of Latin America, Africa, and Southeast Asia, residents increasingly use USD-pegged stablecoins like USDT not just for remittances but also as savings tools to hedge against currency depreciation—even in areas where traditional dollar banking services are unavailable.
However, scalability remains a challenge. Public blockchains like Ethereum face throughput constraints during peak usage, leading to higher fees and slower confirmation times. Layer-2 solutions and alternative high-performance chains (e.g., Tron) are helping mitigate these issues, but widespread payment adoption will require continued infrastructure innovation.
Traditional Giants Enter the Stablecoin Arena
Major financial and tech players are no longer观望—they’re actively building or adopting stablecoin infrastructure.
PayPal launched PYUSD (PayPal USD) in partnership with Paxos, enabling stablecoin payments across millions of online merchants. Walmart and Amazon are reportedly exploring their own branded dollar-pegged tokens to streamline checkout processes and reduce transaction costs. In Asia, Ant Group’s international arm has signaled interest in applying for Hong Kong’s upcoming stablecoin license, while JD.com’s stablecoin project is already in its second phase of regulatory sandbox testing.
Yet market traction varies widely. Despite PayPal’s massive user base of over 430 million active accounts, PYUSD’s circulating supply stood at just $950 million as of mid-2025—pale in comparison to market leaders like USDT ($156B+) and USDC ($61B+). This disparity highlights a crucial insight: user trust and ecosystem integration matter more than brand power alone.
Why Stablecoin Competition Is Fiercer Than It Seems
The "Non-Fungible" Nature of Fungible Tokens
At face value, all USD-pegged stablecoins should be interchangeable—one dollar is one dollar. But in practice, they aren’t perfectly fungible due to differences in issuance transparency, regulatory compliance, chain compatibility, and ecosystem support.
Think of it like USB ports: while all carry data, a USB-C cable won’t fit into a micro-USB device. Similarly, USDT on Ethereum cannot directly interact with USDC on Solana without bridging or swapping mechanisms.
This “non-homogeneity” creates competitive dynamics. On Coinbase, for instance, trading volume for USDC pairs was only about 1/8th that of USDT pairs in June 2025—despite Coinbase being USDC’s issuer. Why? Because USDT enjoys broader acceptance across exchanges, DeFi protocols, and peer-to-peer networks, especially in emerging markets.

Building Moats Through Ecosystem Utility
Market dominance isn’t determined by issuance alone—it hinges on utility across use cases:
- Remittances: USDT dominates in Latin America and Southeast Asia due to established off-ramps.
- DeFi: USDC leads in regulated lending platforms like Aave and Compound due to compliance assurances.
- Institutional Payments: Circle’s USDC is favored by fintechs integrating via APIs thanks to strong audit trails.
The winner in the stablecoin race won’t necessarily be the one with the best backing—but the one embedded deepest into everyday financial workflows.
Stripe’s acquisition of Bridge for $1.1 billion underscores this trend. Its USDB stablecoin allows businesses to accept fiat or crypto and pay out globally using programmable stablecoin rails. By abstracting away the complexity between traditional banking and blockchain systems, Stripe is building a hybrid infrastructure where stablecoins serve as interoperable settlement layers.
Still, performance lags behind legacy systems. While Alipay handles over 250,000 transactions per second during peak events, even high-throughput blockchains like Tron manage only ~2,000 TPS—highlighting the need for ongoing scalability improvements before mass retail payment adoption.
Emerging Frontiers: Tokenized Stocks and AI Agents
Tokenized U.S. Equities – The Next Catalyst for Stablecoin Demand
Stock tokenization—the process of representing real-world equity shares as blockchain tokens—is gaining momentum. Unlike earlier experimental platforms like Mirror Protocol (which faded amid regulatory scrutiny), today’s efforts involve major institutions pushing for compliant frameworks.
Coinbase is reportedly seeking SEC approval to offer tokenized stocks, allowing users to trade fractional shares of Apple, Tesla, or Nvidia directly on-chain using stablecoins. Kraken has partnered with Backed Finance to launch xStocks, offering non-U.S. clients exposure to over 50 U.S.-listed equities via tokenized instruments.
These developments could unlock trillions in new demand for stablecoins as settlement mediums. Investors would buy tokenized stocks using USDC or USDT, creating recurring flows between off-chain capital and on-chain markets.
Regulatory clarity from jurisdictions like Hong Kong and Switzerland is accelerating this shift. As institutional confidence grows, tokenized equities may become the largest driver of stablecoin usage beyond remittances.
AI Agents and Autonomous Financial Interactions
AI agents—autonomous software entities capable of executing tasks independently—are becoming central to Web3 automation. Stablecoins provide the ideal payment layer for these agents due to their programmability, low friction, and 24/7 availability.
Traditional bank accounts require multi-step authorization processes ill-suited for machine-to-machine interactions. But with blockchain wallets, an AI agent can execute payments instantly upon meeting predefined conditions—enabled through smart contracts.
Consider intent-based trading: a user specifies a goal (“swap Token A for Token B at optimal price”), and an AI agent finds the best path across multiple decentralized exchanges (DEXs), executing swaps seamlessly using stablecoins as intermediate mediums.
Protocols leveraging this model—like CowSwap or Anoma—are proving that AI + stablecoins = autonomous finance. In the future, AI assistants could manage subscriptions, rebalance portfolios, or pay invoices—all without human intervention.
Regulatory Challenges: Security, Compliance, and Systemic Risk
Despite their promise, stablecoins face critical hurdles:
- Private key management: Individuals risk permanent fund loss if keys are lost; enterprises face internal control risks.
- Custody solutions: While firms like Coinbase Custody offer institutional-grade storage, custodial models conflict with decentralization principles.
- Regulatory arbitrage: Unregulated stablecoin flows can facilitate capital flight or illicit activities—UNODC reported in 2024 that USDT was exploited for money laundering in Southeast Asia.
- Dollar offshoring: Unlike CHIPS (which handles ~95% of global USD settlements), blockchain-based dollar movements evade centralized oversight.
U.S. and Hong Kong regulators are responding with licensing regimes aimed at ensuring reserve transparency and anti-money laundering (AML) compliance. These frameworks won’t stifle innovation—they’ll legitimize it.
