Stablecoins: The "Digital Dollars" Powering Crypto, Payments, and the Future of Money

Stablecoins have become the foundation of crypto markets and increasingly, the traditional financial system. When I first started researching digital assets, I found stablecoins difficult to grasp. They seemed too simple to be important, yet were everywhere. Years later, I've watched this category grow from a niche trading tool to a $320+ billion market that processes trillions in annual volume.

Coinminutes has spent years analyzing stablecoin mechanics, risks, and real-world adoption across different markets. This guide explains stablecoins from the ground up.

1The Basics of Stablecoins

Let's start with the fundamentals: what stablecoins actually are, why they exist, and how they differ from other cryptocurrencies.

Simple Definition of Stablecoins

Stablecoins are cryptocurrencies designed to maintain a stable value relative to a reference asset, usually the U.S. dollar. The value of an asset such as Bitcoin can fluctuate by up to 10% in a single trading day. On the other hand, a stablecoin like USDC or USDT has the goal of maintaining a value of $1.00 per unit.

Stablecoins are cryptocurrencies pegged 1:1 to the U.S. dollar.

The term “stablecoin” reflects its purpose: a digital token designed to hold a relatively stable price. Most stablecoins are pegged 1:1 to the U.S. dollar, though euro-denominated and other fiat-pegged versions exist.

Why Stablecoins Exist

Stablecoins help solve several real-world problems:

• Volatility protection: If you are holding Bitcoin, you can convert gains into a stablecoin designed to track the value of the U.S. dollar.

• 24/7 settlement: Banks have regular business hours. Blockchain networks don't. So if you need to make a transaction at any time, stablecoins are always available.

• Programmability: You can automate usage of a stablecoin within smart contracts and decentralized applications. This is difficult to do with traditional bank dollars without relying on intermediaries and additional infrastructure.

• Cross-border efficiency: Moving traditional currency across borders requires days and significant charges through traditional banking. However, with stablecoins, the transaction takes seconds or minutes and costs almost nothing.

Stablecoins offer volatility protection, 24/7 settlement, programmability, and faster, cheaper cross-border transfers.

The "Digital Dollar on Blockchain Rails" Analogy

A stablecoin is best understood as a digital dollar running on blockchain rails. They represent dollar value and exist as tokens on blockchain networks like Ethereum, Tron, or Solana rather than as numbers in a bank database. 

This makes a big difference because you do not need permission from an intermediary to send value directly to another person. Additionally, stablecoins can be programmed into automated applications and can settle transactions instantly on weekends or holidays.

Stablecoins vs Normal Cryptocurrencies

Unlike stablecoins, cryptocurrencies like Bitcoin and Ethereum are not pegged to an external asset, so their prices move freely based on supply and demand. Therefore, their value tends to be highly volatile. 

Stablecoins were created with the intent to hold a stable price. They achieve this through different backing mechanisms. Instead of offering potential upside from price appreciation, they offer price consistency.

For that reason, stablecoins are generally not used as speculative investments. However, they can be utilized for payment purposes, create trading pairs, and store your funds when there is high volatility in the markets.

2How Do Stablecoins Work?

Understanding the mechanics behind stablecoins helps explain why they maintain their value and what can go wrong when those mechanisms fail.

The Peg: Why Most Stablecoins Try to Stay at $1.00

The "$1.00 per unit," or the "$1.00 peg" is the core promise of the dollar-pegged stablecoin concept. If that peg is supported by credible mechanisms, users can usually trust that each token is redeemable for about one dollar.

Depending on which category of stablecoin you look at, there may be many ways to support the peg. However, they all have the same universal objective: to make sure the current market value is as close to $1.00 as possible at all times.

Minting and Redemption Explained Simply

Most popular stablecoins use the minting and redemption method:

• Minting: An approved user transfers $1 million to the stablecoin issuer. The issuer will create one million new tokens (one for each dollar) and give these to the approved user. The money is deposited into their reserves.

• Redemption: An approved user returns 1 million tokens back to the issuer. The issuer then deletes or "burns" those returned tokens and sends the equivalent of $1 million in cash from their reserves.

Together, minting and redemption help create a practical price floor and ceiling around the peg. Only institutions that are vetted typically have the ability to mint and redeem directly.

Major stablecoins maintain their peg through minting and redemption.

Why Arbitrage Helps Keep the Price Stable

If a trader has access to redeem their tokens and sees that USDC is trading at $0.995 on an exchange, they will be able to purchase those cheaper tokens and then redeem them for $1.00. Those actions create purchasing pressure which brings the price closer to $1.00.

On the flip side, if there are traders who have redemption available and see that the USDC is at $1.005, they would be able to mint new tokens using the $1.00 redemption price and then sell them for $1.005. That action creates selling pressure to bring the price of the token lower.

This arbitrage mechanism works properly as long as redemption is reliable, fast, and accessible. If this fails (as it did during the March 2023 Silicon Valley Bank Crisis), you may see large deviations from the peg.

Reserves: The Foundation of Many Stablecoins

Most major fiat-backed stablecoin issuers, such as Circle and Tether, rely on reserves that typically consist of short-term U.S. Treasury bills, overnight repos, and cash.

Reserve quality varies widely from one issuer to another. The better issuers will post monthly attestations performed by accounting firms that verify that the reserves match or exceed circulating supply.

Fiat-backed stablecoins depend on reserve quality.

Why Reported Volume Can be Misleading

Stablecoin “volume” is often reported as extremely high. Unfortunately, this number is often greatly exaggerated.

According to an analysis done by Boston Consulting Group and Allium Labs in 2026 of on-chain data for 2025, stablecoin gross on-chain transfers were over $62 trillion. However, after eliminating bot traffic (and internal routing), intermediary transactions, etc., that figure was reduced to about $4.2 trillion in what could be called “economically significant volume.” Only $350-$550 billion were real economy payments for goods or services.

So when you read “stablecoins have moved more volume than Visa”, that is almost certainly comparing gross transfer amounts with net payment volumes - two very different metrics.

3The Main Types of Stablecoins

Not all stablecoins work the same way. Each are designed differently and offer different trade-offs between simplicity, decentralization, and risk.

Fiat-backed Stablecoins

Fiat-backed stablecoins account for the majority of the stablecoin market by capitalization. They function by holding fiat currency or cash-equivalent assets in reserve, with each token representing a claim on those reserves.

Fiat-backed stablecoins are backed by reserves such as cash or Treasury bills.

• Examples: USDT (Tether), USDC (Circle), and PYUSD (PayPal) 

• How they work: The issuer holds fiat currency or short-term Treasury assets in reserve. In turn, the investor will purchase tokens which represent a claim on those reserves.

• Pros: Easy to understand, generally maintain their peg well, highest liquidity

• Cons: Requires trust in the issuer, subject to regulatory and banking risks

The GENIUS Act signed in the U.S. in July 2025 established a new federal regulatory regime for payments stablecoins. This new regime will require issuers to hold reserve funds in cash, Treasury bills, and other high-quality assets.

Crypto-backed Stablecoins

Crypto-backed stablecoins use other cryptocurrencies to back them rather than fiat currency. Because crypto assets are volatile, these stablecoins require over-collateralization.

Crypto-backed stablecoins use cryptocurrency collateral instead of fiat reserves.

• Examples: DAI (Maker DAO), USDS (Sky Protocol)

• How they work: Backed by using other cryptocurrencies as collateral. However, because the underlying value of those collateralized cryptocurrencies can be highly volatile, there must be an over-collateralization requirement in order to maintain stability (lock $150 of Ethereum to receive $100 of stablecoin tokens).

• Pros: Transparent on-chain collateral, do not rely on traditional banking systems

• Cons: Capital inefficiency, smart contract risks, vulnerable during severe market crashes

Algorithmic or Synthetic Stablecoins

Algorithmic or synthetic stablecoins do not rely on traditional fiat reserves, but instead use algorithmic mechanisms or synthetic hedging strategies to maintain their peg.

Algorithmic or synthetic stablecoins try to maintain their peg through automated mechanisms or hedging strategies.

• Example: USDe (Ethena)

• How they work: Utilize algorithmic mechanisms or synthetic hedging strategies. USDe holds crypto assets and offsets their price exposure with short futures positions, thus providing the theoretical stability of dollar value.

• Pros: Can be scaled without reserve equivalency of fiat currency, can provide yield

• Cons: Complex mechanisms that may fail under stress, regulatory status unclear

The Terra/Luna collapse in May 2022 showed how fragile algorithmic stablecoins can be under stress. Over $40 billion in value was lost from this failure.

Tokenized Treasury and Yield-bearing Dollar Products

A newer category sits between stablecoins and investment products: tokenized money market funds and Treasury products.

Tokenized Treasury and yield-bearing dollar products hold short-term Treasuries and pass yield to investors.

• Examples: BUIDL (BlackRock), USYC (Circle/Hashnote), USDY (Ondo Finance), YLDS (Figure Markets)

• How they work: These products hold short-term U.S. Treasuries and pass that yield through to investors. However, unlike other stablecoins which maintain a price of $1.00 per unit, these products track net asset value and accrue yield. They're regulated as investment funds rather than payment tokens.

• Important distinction: These are technically not stablecoins. As the value of the product varies based upon the current yield, this creates competition for “tokenized dollar” or “stablecoin like” use cases among stablecoin issuers.

• Pros: Offer yield to investors, operate under investment-fund laws, backed by high-quality, transparent assets

• Cons: Not payment stablecoins (price varies with accrued yield), may require investor certification, less integrated into DeFi applications

4Why Stablecoins Matter: Real Use Cases Beyond Trading

Beyond speculation and trading, stablecoins are solving real-world problems in payments, business operations, and financial infrastructure.

Trading and Exchange Liquidity

The original and still most common use of stablecoins is as quote currencies on crypto exchanges. Instead of conducting a transaction with BTC/USD via banking integration, exchanges offer BTC/USDT or ETH/USDC pairs. This provides faster, 24/7 trading without requiring traditional banking infrastructure for every trade.

Stablecoins provide liquidity that enables the functionality of crypto markets. Most of the trading volume within the crypto ecosystem occurs using stablecoin pairings instead of fiat pairings.

DeFi Lending, Borrowing, and Liquidity

The use of stablecoins is a vital component of decentralized finance (DeFi) applications. Users can:

• Deposit stablecoins into lending protocols to receive yields on their deposits

• Borrow stablecoins against cryptocurrency collateral without having to sell their cryptocurrencies

• Provide liquidity to stablecoins in decentralized exchanges

• Utilize stablecoins as collateral in derivatives and options contracts

Most DeFi applications use stablecoins because they remove price volatility from core protocol mechanics.

Cross-border Payments and Remittances

Traditional payment corridors typically have a total cost (combined fees + spreads) ranging from 5-8% and take 1-3 business days. Stablecoin-based corridors can lower their total cost to a range of 1-2.5% for compliant services or less than 1% peer-to-peer, and settle transactions in minutes.

Stablecoins can make cross-border payments faster and cheaper than traditional remittances.

Research suggests that adoption is especially strong in corridors involving Turkey, Argentina, Nigeria, and Vietnam. In these countries, stablecoins account for approximately 20-40% of all cross-border consumer transfer flows. The dominant choice is USDT on Tron due to extremely low fees.

Business Settlement and Treasury Operations

More and more corporations are using stablecoins for:

• Same-day business-to-business settlements 

• Cross-border payments to suppliers and contractors

• Treasury management and liquidity operations

• Invoice settlement without currency conversion

In my research for Coinminutes, I've clearly seen that businesses are focusing more and more on speed, cost, and integration with existing accounting systems. Bank-issued deposit tokens, such as JPMD from JPMorgan, are now competing with stablecoins in many of these use cases by offering similar benefits within a traditional regulatory framework.

Tokenized Finance and Settlement Rails

Tokenizing bonds, stocks, or other forms of financial instruments also requires a tokenized cash leg so both sides of the transaction can settle on-chain. The instant atomic delivery-versus-payment settlement process is then possible in place of multi-day settlement cycles, which may save billions of dollars in potential settlement costs. 

Major institutions including JPMorgan, Goldman Sachs, and HSBC have production platforms using stablecoins or bank deposit tokens for securities settlement.

5The Stablecoin Market in 2026: Who Dominates and Why?

The stablecoin market is dominated by just two players, but understanding the competitive landscape reveals why and what it means for users.

Market Size: Why Different Sources Show Different Totals

According to the data available at mid-2026, the total stablecoin market is estimated to be a minimum of $290 billion with some estimates suggesting it could reach or exceed $322 billion. The variations are primarily due to differences in how each estimate was developed (the inclusion criteria) and whether yield-bearing tokens that are not strictly pegged to $1.00 were included. 

Since the beginning of 2025, there has been a significant increase in the size of this market having reached about $207 billion. This represents an increase of roughly 50% over a one-year period.

USDT and USDC: The Two Giants

Two stablecoins dominate the market to an extraordinary degree:

• USDT: ~$184-$189 billion (59-60% market share)

• USDC: ~$73-$79 billion (24-25% market share)

Together, they account for around 83% of all stablecoins currently on the global market.

USDT and USDC dominate the stablecoin market.

Tether (USDT) was first launched in 2014, operates primarily outside the United States and has taken a significant position in remitting funds from emerging economies. In Q1 2026, Tether announced that it had earned a net income greater than $1 billion with more than $141 billion in exposure to the U.S. Treasury. 

Circle (USDC) launched in 2018, became listed publicly on the NYSE in June 2025 and positioned itself as the regulatory-compliant U.S. alternative. Most of USDC’s reserves are managed by BlackRock through a money market fund held at BNY Mellon.

As stated above, each serves different types of customers. USDT has a strong presence in both offshore exchanges and retail cross-border payments. In contrast, USDC has a large client base within the institutional markets and compliance-focused DeFi ecosystems in the U.S.

Why the Stablecoin Market Is so Concentrated

It is no coincidence that the market for stablecoins is so concentrated. In fact, there are at least four additional competitive advantages (each one compounded by having a larger scale) that contribute to this concentration:

• Liquidity depth: Trading pairs tend to be developed for the most liquid stablecoins.

• Redemption credibility: The reputation of being able to redeem your coin has taken many years to establish. There is no way for a new issuer to create the same level of credibility in such a short period of time.

• Multi-chain presence: Many of the top stablecoins have been deployed on multiple (20 or more) blockchain platforms.

• Integration depth: A number of stablecoins have been fully integrated into card networks, exchanges, wallets and DeFi protocols which was a time-consuming process.

These moats compound over time, making concentration the predictable outcome.

Important Stablecoins Beginners Should Recognize

Beyond USDT and USDC:

• USDS (Sky Protocol): ~$7.9-$10.9 billion, a crypto-backed stablecoin evolved from MakerDAO

• DAI (MakerDAO): ~$4.6 billion, the original crypto-backed stablecoin

• PYUSD (PayPal): ~$3.5-$4.1 billion, integrated into PayPal and Venmo

• FDUSD (First Digital): ~$347 million, popular on certain Asian exchanges

• USDG (Global Dollar Network): ~$2.8 billion, MAS-regulated in Singapore

There are some euro-denominated stablecoins available, but they are significantly less popular than those that are dollar-denominated. For instance, there is Circle’s EURC with around €447 million available at present. The entire euro stablecoin market is roughly 450 times smaller than dollar stablecoins.

Chains Matter: Ethereum, Tron, Solana, Base, and Beyond

The total stablecoin supply is distributed across multiple blockchain networks, and which network a stablecoin is deployed on will provide insight into the intended use cases.

• Ethereum: ~$162-$170 billion, is still the most popular platform for institutional use DeFi applications, and large transfers

• Tron: ~$86-$87 billion, provides the majority of low-cost retail remittances

• Solana: ~$15-$16 billion, is emerging as an alternative to Ethereum for high-frequency trading and micropayments

• Base: ~$7.5 billion, Coinbase’s Layer-2 solution, is being increasingly adopted by institutions

• BNB Chain: ~$11 billion, is being used retail and Asian exchange-related uses

• Others: ~$2-$5 billion each, including Polygon, Arbitrum, Avalanche, Stellar, etc.

Chain selection is now a routing decision. Advanced treasury systems are beginning to route transfers through the best possible blockchain network, taking into account fee, speed, and integration considerations based on the transfer amount, counterparties, and intended use case.

6Stablecoin Risks, Regulation, and How to Evaluate Them

Every stablecoin carries risks, and knowing how to evaluate them is essential before committing significant capital or building business processes around them.

Depegging Risk

Stablecoins are most vulnerable to depegging risk. When this risk materializes, it represents an unstable or non-stable relationship in terms of the market value of a stablecoin vs. its target peg of $1.00.

Depegging occurs when redemptions become uncertain. When users doubt whether they can redeem their tokens for $1.00, they are going to begin selling their tokens on the open market at reduced prices. Since no one has confidence that an arbitrageur will purchase their tokens and then redeem them, the discount may grow substantially.

Depegging risk occurs when users lose confidence that a stablecoin can be redeemed for $1.

Reserve and Transparency Risk

In fiat-backed stablecoin reserves, there are several risks to reserve quality. These include:

• Insufficient reserves: The issuer holds less than 100% backing for circulating tokens

• Poor reserve quality: Reserves include risky assets that might not be liquid or might lose value

• Lack of transparency: The issuer provides inadequate disclosure about reserve composition

• Banking concentration: Reserves held at a small number of banks create single-point-of-failure risk

The best issuers will provide monthly attestations from reputable auditing firms. In my evaluation of stablecoins for Coinminutes, I start with how often you receive attestations from reputable auditing firms, consider the reputation of the accounting firm, and then evaluate the quality of your reserve assets.

Issuer and Redemption Risk

Although reserve levels are typically sufficient to cover redemptions, many potential problems still exist:

• Redemption access: Most issuers will not permit retail investors to directly redeem their tokens. Instead, retail investors must rely on an exchange or intermediary to complete this process

• Redemption windows: In addition to determining whether the funds will be available immediately or within one trading day (T+1), you should also consider how long it may take to receive payment after submitting a redemption request

• Minimum redemption sizes: Some issuers require that there be a minimum of $100,000 worth of tokens for direct redemption

• Bankruptcy priority: If the issuer fails, what is your legal claim to reserves? This varies significantly by jurisdiction and legal structure

NYDFS-supervised trust companies (Paxos, Gemini) structure reserves in bankruptcy-remote accounts held in trust for token holders. Circle holds most reserves in a registered money market fund. Tether's offshore structure provides less clear bankruptcy protection.

Smart Contract and Bridge Risk

Smart contracts and bridges both present a significant risk of failure:

• Smart contracts can have bugs that lock up funds or allow unauthorized minting or redemption of stablecoins

• Bridges are vulnerable to exploits as over $2.5 billion in losses have occurred since 2022 due to the following examples of third-party bridges being compromised (Wormhole, Ronin, Nomad, Multichain, etc.)

• Upgrades are also an issue for almost all stablecoin contracts as they typically use issuer-controlled admin keys for upgrade purposes. Although using these keys allows the contract bug fixes, it also gives them unilateral ability to change how the contract behaves

Native cross-chain mechanisms like Circle's CCTP are safer than third-party bridges because they eliminate custody by bridge operators.

Stablecoins face smart contract, bridge, and upgrade risks, with third-party bridges especially vulnerable.

Regulatory Risk

There have been tremendous changes to the regulatory environment surrounding stablecoins: 

• United States: GENIUS Act (signed July 2025) creates comprehensive federal framework requiring high-quality reserves and federal or state supervision

• European Union: MiCA regulation (full effect July 2026) requires authorization as e-money token issuers or asset-referenced token issuers. Tether has been delisted from major EU venues for non-compliance

• Singapore: Since June 1, 2023, the Monetary Authority of Singapore’s single-currency stablecoin license is available, with licensing under the broader Digital Token Service Provider regime

• Hong Kong: The Stablecoin Ordinance which created a licensing structure via the Hong Kong Monetary Authority was passed in August 2025

Regulatory risks are two-edged. A clear regulatory framework (GENIUS Act) creates certainty and encourages institutions. Regulatory actions directed at a specific stablecoin (NYDFS issued cease and desist order closing Binance USD in February 2023) can rapidly eliminate a multi-billion-dollar product.

Confusing Stablecoins with Bank Deposits

One of the most serious misconceptions: stablecoins aren't bank deposits and don't typically have deposit insurance coverage.

When you hold USDC or USDT, you have a claim on the reserves held at Circle or Tether. You are not a depositor. Your right to recover from those reserves in the event of failure depends on the terms of the agreement under which the reserve was created. Specifically, it will depend on applicable law in the relevant jurisdiction and the outcome of subsequent bankruptcy proceedings, not on deposit insurance.

Stablecoins are not insured bank deposits.

How to Evaluate a Stablecoin Before Using It

Before you use a stablecoin, ask these questions:

• Who issues it? Research reputation and regulatory status.

• Where are the reserves? Are they disclosed transparently?

• Who attests the reserves? Monthly attestations by reputable firms are minimum standard.

• What is the redemption process and timeline?

• What jurisdiction and regulation applies?

• What is the market depth and liquidity?

• Which chains is it deployed on?

For most users, using either USDT or USDC will provide protection through their established track records, high liquidity, and widespread integration. Smaller or newer stablecoins may have specific advantages to offer, but they also bring with them significant risk.

7A Final Word on Stablecoins

Stablecoins have evolved from niche trading tools into foundational infrastructure connecting traditional finance with blockchain applications. By providing additional payment paths and empowering financial services that could never be implemented using traditional banking infrastructures, the growth in this market has opened up vast possibilities. 

However, there exist significant risks. The reserve backing of each stablecoin matters. Regulatory requirements also must be met and reliable redemptions of funds matter. The large concentration of reserves behind USDT and USDC can be attributed to their long-term competitive advantage. 

At Coinminutes, we have observed stablecoins evolve from experimental tokens to financial infrastructure. As such, if you are a trader, a business looking at quicker settlements, or an individual simply interested in how money is evolving, it will become increasingly important to understand stablecoins. The category is no longer experimental; it is infrastructure enabling the next generation of digital finance.
