The numbers are in. EURe, the flagship euro-denominated stablecoin issued by Monerium, now holds a mere 2% share in crypto card payments. USDC swallowed the rest. This isn't a blip. It's a verdict.
For months, the narrative was clear: MiCA would be the great equalizer. European regulation would force dollar stablecoins out of the EU, and euro stablecoins like EURe would inherit the payment rails. The data tells a different story. In the one metric that matters—real-world spending—EURe is being systematically marginalized. USDC isn't just winning; it's becoming the default settlement layer for crypto cards, and the margin is widening.
Context: Why We Expected More
EURe was designed as the regulated euro alternative. Monerium holds an electronic money institution (EMI) license in Iceland, operates under the European Economic Area framework, and has been positioning itself as the compliant euro stablecoin for the MiCA era. USDC, issued by Circle, is a dollar stablecoin under U.S. state regulation, but it has aggressively expanded into Europe, securing partnerships with Visa, Mastercard, and major card issuers like Wirex and Crypto.com.
The expectation was that MiCA would create a regulatory moat for euro stablecoins. But the data from the crypto card segment—where stablecoins are actually used for daily purchases—shows that compliance alone doesn't drive adoption. Users choose convenience, liquidity, and trust. USDC has all three. EURe has only the regulatory stamp.
Core: The On-Chain and Off-Chain Truth
Let's start with the technical side. Both EURe and USDC are ERC-20 tokens, backed by fiat reserves, and issued by centralized entities. The code is nearly identical. The real difference is in the banking rails. Circle has built a multi-chain infrastructure with native support for Ethereum, Solana, Avalanche, and over a dozen other networks. Its API suite allows card issuers to integrate USDC settlement in days, not weeks. Monerium, by contrast, has limited chain support and a less mature developer toolkit.
But the deeper issue is liquidity. Volume spikes lie; liquidity flows tell the truth. USDC has a market cap of over $30 billion; EURe's is a fraction of that. In crypto card payments, the issuer needs to pre-fund settlement accounts with the stablecoin. A larger market cap means deeper on-chain liquidity, tighter spreads, and lower slippage when converting between fiat and stablecoin. EURe's thin liquidity makes it a second-class asset for card programs. Issuers prefer USDC because they can move large amounts without moving the market.
Then there's the dollar hegemony effect. The chart doesn't lie, but the narrative does. The MiCA narrative promised that euro stablecoins would gain share as European regulators cracked down on dollar stablecoins. But the reality is that merchants and consumers don't care about the stablecoin's denomination. They care about final settlement. USDC settles in dollars, which are accepted globally. A euro-denominated stablecoin only makes sense if the merchant is invoiced in euros and wants to avoid FX conversion costs. That's a niche use case, and the data shows it's not growing.
Speed is safety when the exploit is already live. In 2020, during the Curve treasury drain, I learned that real-time on-chain vigilance separates the informed from the victims. The EURe decline is not a sudden exploit; it's a slow bleed. But the same principle applies: if you wait for the official announcement, you're already behind. The 2% share is not a new development; it's the culmination of a trend that has been visible in on-chain volumes for months. EURe's daily transfer volume on Ethereum has been declining since Q1 2024, while USDC's payment volume has surged.
From a tokenomics perspective, EURe has no value capture mechanism. It's a pure payment token. The incentive to hold it is purely transactional. When the payment use case shrinks, the holding demand evaporates. USDC, on the other hand, benefits from the Circle's yield-bearing products (e.g., Circle Yield) and the ability to earn interest through Treasury bills. Euro stablecoins lack a similar yield because the ECB interest rate is lower and the regulatory framework for passing through interest is less developed. This creates a structural disadvantage for EURe.
Contrarian: The Blind Spots in the USDC Dominance
The conventional wisdom says that USDC's dominance is unassailable. But that's a dangerous assumption. The same single-point-of-failure risk that haunts Bitcoin exchanges applies here. If Circle faces a regulatory crackdown, a banking partner failure, or a reserve audit scandal, the entire crypto card payment ecosystem could be disrupted. The 2% share for EURe might look pathetic, but it also means EURe is a hedge against USDC centralization. In a black swan event where USDC becomes temporarily unbacked—like the Silicon Valley Bank crisis that briefly depegged USDC in March 2023—EURe could become the only standing euro stablecoin for emergency payments.
Furthermore, the MiCA regulations are still being implemented. While USDC is actively seeking a European license, the process is not guaranteed. Circle has applied for a MiCA license but has not yet been approved. If the European Securities and Markets Authority (ESMA) decides that USDC's U.S. reserve structure doesn't meet the local custody requirements, EURe could gain a temporary regulatory monopoly. However, that's a long shot. The data shows that even with theoretical regulatory advantages, EURe hasn't converted them into market share.
Another blind spot: the 2% share might be a floor, not a ceiling. In crypto card programs, the stablecoin choice is often dictated by the card issuer's treasury management. If one major issuer drops EURe entirely, the share could drop to near zero. But if another issuer decides to add EURe for euro-denominated cards, the share could bounce back. The 2% figure is aggregate across all crypto card programs. Breaking it down by region could reveal pockets of strength. For example, EURe might have 20% share in German-issued crypto cards, but that's diluted by the dominance of U.S. card programs. The headline share masks granular dynamics.
Takeaway: What to Watch Next
The next six months will determine whether EURe survives as a niche euro stablecoin or fades into irrelevance. Watch for three signals: first, the onboarding of new card issuers. If Monerium announces partnerships with major European neobanks like N26 or Revolut, the share could recover. Second, the MiCA implementation timeline. If the European Banking Authority (EBA) issues final guidelines that require all stablecoin issuers to hold reserves in EU banks, USDC may temporarily lose access to the European market. Third, the on-chain velocity of EURe. If the number of active addresses holding EURe continues to decline, the token is in a death spiral.
We don't use the word 'reset' lightly, but for EURe, the reset button is already pressed. The question is whether Monerium can pivot to a different value proposition—perhaps as a regulated euro stablecoin for institutional DeFi or for cross-border B2B payments—before the card payment share becomes zero. The data is clear: the crypto card train has left the station, and USDC is the conductor. The euro stablecoin dream is not dead, but it's on life support. And the meter is running.
