1. What are stablecoins?
Stablecoins are the quiet engine of Web3, powering nearly every corner of onchain activity, from DeFi lending to NFT trading and cross-border settlements. These cryptocurrency have been designed to maintain a 1:1 peg to fiat currencies, therefore they’ve become the primary bridge between traditional finance and blockchain economies.
But their evolution is far from static. In just a few years, stablecoins have expanded from simple tokenized dollars to a diverse ecosystem of financial instruments, each with different risk models, levels of decentralization, and design goals. Understanding how they work, and how they differ, is key to seeing where the next phase of digital money is heading.
Today’s stablecoins can be analyzed along two key dimensions:
- Collateral model: ranges from fully fiat-backed to crypto-collateralized and synthetic.
- Governance model: ranges from centralized corporate issuers to decentralized autonomous protocols.
When these two dimensions intersect, they define the three main categories of stablecoins we see today:
- Fiat-backed stablecoins (centralized and fully reserved)
- Asset-backed stablecoins (decentralized and crypto-collateralized)
- Strategy-backed synthetic dollars (SBSDs) — a newer class that combines elements of both stability and yield generation.
1. Fiat-Backed Stablecoins
Fiat-backed stablecoins mirror the principle of traditional money issuance. Every token represents a claim on real-world reserves, usually held in cash or short-term U.S. Treasuries. Their value depends on issuer credibility and convertibility through exchanges such as Coinbase or Uniswap. As of October 2025, fiat-backed stablecoins represent over 90% of total supply, solidifying their dominance in the ecosystem.
Tether (USDT)
Launched in 2014 by Tether Limited, USDT remains the most traded and widely adopted stablecoin across multiple chains, primarily Ethereum.
Market snapshot (October 2025)
- Market cap: $183 billion
- 24-hour trading volume: $109 billion
- Dominance: 59% of total stablecoin market
- Growth since 2023: +120% market cap, +890% trading volume
Tether’s scale makes it the liquidity backbone of the crypto economy, despite periodic controversy over reserve transparency.
USD Coin (USDC)
Issued by Circle and Coinbase, USDC is the most regulated and institutionally integrated stablecoin, fully backed by U.S. dollar reserves.
Market snapshot (October 2025)
- Market cap: $76 billion
- 24-hour trading volume: $8.5 billion
- Dominance: 24%
- Growth since 2023: +192% market cap, +183% trading volume
2. Asset-Backed Stablecoins
Asset-backed stablecoins are minted through decentralized lending, where users deposit onchain collateral such as ETH or tokenized Treasuries to generate new stable tokens. This mirrors how banks expand money supply via credit, except here, everything is transparent and programmable onchain.
Sky (USDS – formerly DAI)
Created by MakerDAO and rebranded to USDS in 2024, this stablecoin continues to define decentralized collateral-backed design.
Market snapshot (October 2025)
- Market cap: $9 billion
- 24-hour volume: $14 million
- Growth: +138% market cap, but -72% trading volume since rebrand
- Dominance: 2.8%
3. Strategy-Backed Synthetic Dollars (SBSDs)
A newer category, SBSDs are $1-pegged tokens backed not by static collateral but by active investment strategies, such as yield farming or basis trading. While they can generate returns, they behave more like tokenized hedge-fund shares than stablecoins, introducing exposure to market risk and centralized exchange dependency.
Ethena (USDe)
Founded in 2023, Ethena Labs developed USDe, a synthetic dollar maintaining its peg through delta-neutral positions rather than direct reserves.
Market snapshot (October 2025)
- Market cap: $10 billion
- 24-hour trading volume: $450 million
- Dominance: 3.2%
Ethena currently is the 3rd largest stablecoin, and its rapid growth highlights a new wave of “yield-bearing dollars”, though they remain structurally different from traditional stablecoins in terms of transparency and risk.
By October 2025, the total stablecoin market cap has reached $312 billion, comparable to the size of a top-20 U.S. bank or the economy of Finland. Stablecoins now represent the core liquidity layer of Web3, powering everything from trading and remittances to DeFi collateral and onchain payrolls.
2. Stablecoins regulation: building trust in digital money
As stablecoins evolve into the core liquidity layer of Web3, regulation has become critical to ensure stability, transparency, and consumer trust. Their goal is simple: maintain a 1:1 peg to fiat currencies and act as reliable, borderless digital money. But history shows what happens when that promise fails.
The collapse of TerraUSD (UST) in May 2022 wiped out nearly $60 billion in market value and triggered a domino effect across DeFi, highlighting the systemic risks of poorly collateralized models. Since then, policymakers have accelerated efforts to bring stablecoins under formal supervision.
While countries across Asia (notably Singapore, Japan, and Hong Kong) have already introduced licensing regimes or pilot programs, the most comprehensive rules so far come from the United States and the European Union.
The United States: GENIUS Act
Signed into law in July 2025, the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act established the first federal framework for payment stablecoins.
It sets clear standards for:
- Licensing and supervision of issuers;
- 1:1 reserve backing and regular audits;
- Consumer protection and redemption guarantees.
The GENIUS Act positions compliant stablecoins as part of the U.S. financial infrastructure, opening the door for banks and fintechs to issue digital dollars with regulatory approval.
The European Union: MiCAR
In Europe, the Markets in Crypto-Assets Regulation (MiCAR) entered into force in June 2023, with stablecoin-specific measures applying from mid-2024. It harmonizes requirements across all EU member states, covering:
- Transparency and disclosure obligations for issuers;
- Authorization and supervision by national authorities;
- Reserve and redemption rules to ensure user protection.
Together, these frameworks mark the transition from experimentation to integration. Stablecoins are moving out of legal grey zones and into regulated finance, a necessary step as their combined market cap surpasses $300 billion and their use expands across borders.
In short, regulation is no longer about restricting innovation, it’s about ensuring trust and resilience in the digital money of the future.
3. Stablecoins stats: adoption reaches record highs
Following the rapid expansion and regulatory clarity covered in previous chapters, 2025 has been a breakout year for stablecoins. Usage, holders, and transaction activity all point to one conclusion: stablecoins have officially gone mainstream.
According to Token Terminal, the stablecoin transfer volume, which measures the total value of onchain transfers, reached nearly $41 trillion in 2025. It was driven by the top 10 stablecoins by market capitalization.
Since users pay gas fees for every transaction, this metric is a strong proxy for real demand and transactional utility. To put this in perspective, a16z’s 2025 Crypto Report notes that stablecoin transfer volumes are now almost three times higher than Visa’s annual throughput and approaching the scale of the U.S. ACH banking network, the infrastructure that powers most American bank payments.
Another indicator of growth is the number of unique addresses holding a non-zero stablecoin balance, a proxy for user adoption.
As of October 2025, there are 129 million stablecoin holders, marking a 60% year-over-year increase.
- Tether (USDT) remains the leader with 93 million holders, up 43% YoY, reinforcing its position as the most widely held digital dollar.
Looking at stablecoin senders, the number of unique addresses transferring tokens, we see another sign of adoption momentum.
As of October 2025, there are roughly 26.6 million active senders, a 78% increase compared to 2024.
Every metric, from transaction volume to active addresses, points in the same direction: mass adoption. Stablecoins have evolved from niche trading tools into the most widely used crypto asset class, rivaling traditional payment networks in scale.
4. What can you do with the stablecoins?
After understanding what stablecoins are, how they’re regulated, and how fast adoption is growing, it’s time to ask the practical question: what can you actually do with them?
The traditional financial system still moves slowly and carries high fees. Stablecoins combine the speed and flexibility of crypto with the stability of fiat, unlocking an entirely new set of onchain opportunities. Below are the top use cases shaping the stablecoin economy today.
Borrowing with Stablecoins as collateral
Stablecoins are increasingly used as collateral in DeFi lending protocols. Because their value is stable, they lower liquidation risk compared to volatile assets like ETH or BTC. Users lock stablecoins such as USDC, USDT, or USDS to borrow crypto assets, often to gain exposure or leverage without selling their stable holdings.
Market snapshot (October 2025):
- Total DeFi lending market: $53.1B (+27% QoQ)
- Average borrowing rate: ~6%
- Top protocols: Aave, Compound, Maker (Sky), and Morpho — where utilization rates for USDT and USDC pools often exceed 90%.
Using stablecoins as collateral offers both liquidity and stability, letting users access new opportunities while maintaining a dollar-pegged position.
Lending Stablecoins: turning idle capital into yield
Stablecoins aren’t just a store of value, they’re productive capital. By lending them into DeFi protocols, users earn passive yield while providing essential liquidity.
Typical yield ranges:
- 🟢 Low risk (Aave, Compound, SparkLend): 2–7% APY
- 🟢 Moderate risk (Morpho, Curve pools): 8–14% APY
- 🔴 High risk (Experimental protocols, unaudited farms, or low-liquidity pools): 15–30%+ APY
A balanced portfolio might allocate 70% to low-risk pools and 30% to opportunistic high-yield strategies, mirroring traditional income investing.
Assume a $10,000 stablecoin portfolio spread across both low- and higher-risk strategies. Based on October 2025 averages:
| Allocation | Risk Level | Average APY | Estimated Annual Yield |
| $7,000 (70%) | Low risk (Aave, Compound) | 5% | ≈ $350 |
| $1,500 (15%) | Moderate risk (Curve, SparkLend) | 10% | ≈ $150 |
| $1,500 (15%) | High risk (Experimental protocols, unaudited farms, or low-liquidity pools) | 20% | ≈ $300 |
| Total | — | ≈ 8% blended APY | ≈ $800/year |
Note: These figures are purely illustrative and do not represent financial advice. Actual yields depend on market conditions, liquidity incentives, and protocol performance.
Payments, Payroll & Remittances
Stablecoins are also gaining traction in everyday payments.
- In emerging economies like Venezuela or Argentina, they help preserve value against inflation while reducing remittance fees.
- For businesses and freelancers, stablecoins simplify cross-border invoicing and payroll, cutting settlement times from days to minutes.
Whether through borrowing, lending, or real-world payments, stablecoins are turning digital dollars into active assets. Their growth isn’t just about price stability, it’s about financial accessibility, letting anyone, anywhere, move, earn, and build directly onchain.
The latest development in Web3 is the popularity of x402 Protocol. Designed by Coinbase for use with USDC on Base, but also applicable to other tokens across any EVM chain, x402 allows for automated, seamless and frictionless micropayments for APIs, AI agents, microtransactions and of course decentralized applications. Dive deeper into this topic by reading the x402 Protocol guide.
Closing words
Stablecoins are no longer a side story, they’re becoming the face of Web3’s maturity. In a space once defined by volatility, they’ve introduced stability, trust, and usability. For millions of users, stablecoins are the first real contact point with blockchain, and often, the reason they stay.
As regulation catches up and real-world use cases expand, we’re witnessing the moment where Web3 finally meets traditional finance. Stablecoins are bridging that gap, not by replacing money, but by redefining how it moves, earns, and connects globally.
The next chapter isn’t about hype; it’s about function. With the right tools and compliance, stablecoins could become the invisible engine powering the next generation of the internet economy.
