The competitive focus of stablecoins has clearly shifted—no longer about "who has the larger market cap," but "who can become the default settlement unit in more real-world scenarios." Wallets, payment scenarios, and end-user channels are becoming the decisive factors. Issuance itself is gradually commoditizing, and distribution capability is the real moat.

1. Understand Why "Distribution" Matters More Than "Issuance"
The stablecoin market is currently dominated by the duopoly of USDT (~$184 billion) and USDC (~$73 billion), together accounting for about 83% of the market share.
But the strategy of new players has already changed. MetaMask's mUSD saw its market cap surge from $25 million to $65 million in less than a week, not due to technological differences, but because it directly owns a wallet entry point with over 30 million monthly active users. Stablecoin issuance itself is becoming "commoditized"—the white-label model (Stablecoin-as-a-Service) allows platforms to leverage stablecoin capabilities without building their own reserve and compliance systems. This means differentiation no longer comes from the asset itself, but from who can deliver stablecoins to more users and merchants.
2. Wallets: From "Tools" to "Default Currency Issuers"
Wallets are becoming the most critical part of stablecoin distribution.
MetaMask's mUSD is a typical case. It allows users to buy directly with fiat currency, swap within the wallet, and even spend via the MetaMask card in stores, wrapping the entire closed loop from "onboarding" to "spending" inside the wallet. This essentially upgrades the wallet from a "signing tool" to a "currency issuance and distribution platform."
Telegram once tried to achieve a similar goal with TON, but its 500 million messaging users did not migrate on-chain. The difference with MetaMask is that its users are already on-chain users, requiring no additional behavioral conversion.
3. Payment Scenarios: The "Functional Division" Between the Two Leaders
The divergence between USDT and USDC is already apparent, which in turn confirms that distribution channels are reshaping the competitive landscape:
| Dimension | USDT | USDC |
|---|---|---|
| Primary Scenario | Payments, remittances, B2B settlement | DeFi, on-chain trading |
| H1 2026 merchant payment volume | ~$95 billion | ~$14 billion |
| B2B payment share | ~92% | ~8% |
| Typical circulation network | Tron (~93% supply in non-exchange wallets) | Base, Ethereum |
| June single-chain transfer volume | — | Base ~$2.6 trillion |
USDT's advantage comes from channel distribution—through low-fee chains like Tron and TON and P2P/OTC networks in emerging markets, it has become "digital dollar cash." USDC's advantage comes from protocol integration—stronger composability in DeFi lending, DEXs, and on-chain settlement.
These two paths are not about "which is better," but represent two different distribution logics: USDT reaches end users through payment channels, while USDC embeds into financial infrastructure through DeFi protocols.
4. "The Last Mile" Is the Real Battlefield
Meta's use of USDC to pay creators exposes a deeper problem: stablecoins have proven themselves in "cross-border distribution," but the "last mile" from on-chain dollars to locally spendable balances has not yet been connected.
For average users, what really determines the experience is not "how big the market cap is," but three specific questions:
- Can it immediately enter local life scenarios upon receipt?
- Are conversion costs low enough?
- Who is responsible if something goes wrong?
Stripe's acquisition of Bridge, Mastercard's partnership with Circle to enable stablecoin settlement in the EEMEA region, and Visa's launch of the enterprise-grade Visa Stablecoin Platform (VSP)—these moves show that payment giants are embedding stablecoins into their own settlement networks, not just "supporting stablecoin payments."

5. Practical Guide: How to Assess a Stablecoin's "Distribution Competitiveness"
Step 1: Check if it has a "native wallet entry point"
- What to do: Check whether the stablecoin is natively supported or integrated by default in major wallets (such as MetaMask, Coinbase Wallet, and Telegram Wallet).
- How to interpret: If users need to manually add a contract address to see the balance, distribution is still at the "passively available" stage. mUSD's rapid growth shows that "displayed by default" is orders of magnitude more effective than "can be added."
Step 2: Check whether it is embedded in real payment scenarios
- What to do: Look for clear merchant payment, B2B settlement, or cross-border remittance data for the stablecoin.
- How to interpret: Dune data shows that USDT's merchant payment volume in the first half of the year was about $95 billion, while USDC's was about $14 billion. If more than 90% of a stablecoin's transfer volume comes from internal exchange circulation rather than external payments, it has not yet entered the substantive phase of distribution competition.
Step 3: Check whether it has a "revenue sharing" mechanism to attract channel partners
- What to do: Check whether the stablecoin incentivizes wallets, exchanges, and market makers through reserve yield sharing (like the USDG/Global Dollar Network model).
- How to interpret: For every $1 billion in circulation, MetaMask's mUSD can generate approximately $40 million in annual interest from treasury yields. This model of "yield flowing back to distribution channels" is more sustainable than simple airdrops.
Prerequisites: You are evaluating the long-term competitiveness of a stablecoin project or considering integrating a stablecoin into a wallet/payment product.
Risk Warning: No matter how strong the distribution capability, stablecoins are still subject to regulation and reserve transparency. BIS research points out that the stability of stablecoins depends entirely on the quality of reserve assets and market arbitrage mechanisms. The brief depeg of USDC in 2023 taught us that "compliance" does not equal "risk-free." Additionally, wallets issuing native stablecoins may blur the boundary between "tool" and "platform," raising questions about data ownership and selection bias.
After completing the above analysis, how do you confirm you understand this "distribution war"?
Open CoinGecko or DeFiLlama and look at stablecoin market cap rankings—but if you only look at market cap, you're already behind. More importantly, look at each stablecoin's "on-chain activity distribution": what percentage of USDT supply is on Tron? How many times greater is USDC's transfer volume on Base compared to its market cap? Did mUSD's first-week growth mainly come from Linea or other chains? If you can clearly explain "why a stablecoin with a smaller market cap may be more distribution-competitive than a larger one," it shows you truly understand the essence of this competition. In the next step, if you are choosing a default stablecoin for your users, prioritize those assets already embedded in real payment scenarios and mainstream wallet entry points.
