Key takeaways
- EURC and USDC are both issued in the EU by Circle's French e-money institution, under MiCA. The difference is the currency: EURC is redeemable 1:1 for euros, USDC for dollars.
- Hold EURC when your income and costs are in euros, so you don't take a dollar exchange rate on every step. Hold USDC when your counterparties pay or want to be paid in dollars.
- USDC is far larger and more widely accepted: about $71 billion in circulation against about 434 million EURC. Euro stablecoins as a whole are around 0.3% of the stablecoin market.
- Neither pays interest: MiCA bans issuers and crypto-asset service providers from granting interest on e-money tokens.
The short answer
Choose by currency, not by issuer. EURC and USDC both come from Circle, and in the EU both are issued by the same French e-money institution under MiCA. EURC is redeemable 1:1 for euros, and USDC for dollars.
If your company earns and spends euros, holding EURC avoids converting to dollars and back each time, and the exchange rate risk that comes with it. If your customers pay you in dollars, or your suppliers want dollars, USDC is the better fit: it's well over 100 times larger, more liquid, and accepted almost everywhere stablecoins are.
How they compare
| EURC | USDC | |
|---|---|---|
| Currency | Euro | US dollar |
| Issuer in the EU | Circle Internet Financial Europe SAS, authorized by the ACPR in France | The same entity |
| Status under MiCA | E-money token | E-money token; classified as significant by the EBA in October 2026 |
| In circulation | About 434 million EURC (Circle, 29 October 2026) | About $71.4 billion (DefiLlama, 2 November 2026) |
| Networks | Circle lists 9, including Ethereum, Solana, Base, Avalanche and Stellar | Many more, including Ethereum, Solana, Base, Arbitrum, Polygon and Avalanche |
| Redemption | 1:1 for euros through Circle Mint, for institutional customers | 1:1 for dollars through Circle Mint, for institutional customers |
| Reserves | Euro-denominated, with monthly attestations | Dollar-denominated, with monthly attestations |
| Interest to holders | None | None |
The euro stablecoin market is small
On 2 November 2026, DefiLlama counted about 846 million euros of euro stablecoins in circulation, against about $299 billion of dollar stablecoins. At an exchange rate of about 1.12 dollars to the euro, euro tokens were around 0.3% of the market.
EURC leads that small market, with about 60% of it on DefiLlama's count, ahead of Société Générale-Forge's EURCV at about 23%, then Eurite (EURI) and Monerium's EURe. A bank consortium, Qivalis, plans to add another; see bank-issued stablecoins. DefiLlama's EURC figure, about 506 million, is higher than Circle's because it also counts tokens on more networks; Circle's own figure was about 434 million on 29 October 2026.
Size matters for a business in two ways:
- Liquidity. Converting a large amount of EURC to euros or dollars on the open market moves the price more than the same amount of USDC. Through Circle Mint, redemption is 1:1, but only for institutional customers.
- Acceptance. Fewer exchanges, wallets and payment providers support EURC, and on fewer networks. Before invoicing in EURC, check that your customers can send it.
The rules both tokens follow in the EU
Reserves. Under MiCA's Article 54, an e-money token issuer must keep at least 30% of the funds it receives in separate accounts at credit institutions, and invest the rest in highly liquid, low-risk instruments in the same currency. Circle says the requirement rises to 60% for significant tokens. On 14 October 2026, the European Banking Authority classified USDC as the first significant e-money token in the EU, out of 45 notified under MiCA. From 12 November 2026, the EBA supervises USDC's own funds, reserves, liquidity and recovery and redemption plans; the ACPR keeps the rest.
No interest. MiCA's Article 50 bans issuers of e-money tokens, and crypto-asset service providers, from granting interest on them. So neither EURC nor USDC pays you a return for holding it, in the EU.
Redemption at par. Under MiCA's Article 49, holders of an e-money token have the right to redeem it at any time, at par value. In practice, most businesses redeem through a provider or an exchange rather than with Circle directly.

When EURC fits
- Your revenue and costs are mostly in euros, for example an EU company paid in stablecoins by customers abroad, or a non-EU company with euro suppliers.
- You want to avoid exchange rate risk between receiving a payment and spending it. With USDC, a fall in the dollar against the euro reduces what your balance is worth in euros.
- Your counterparties already hold EURC, so neither side converts.
When USDC fits
- Your customers pay in dollars, or your prices are set in dollars.
- You pay suppliers in dollars, or in currencies that are usually quoted against the dollar.
- You need liquidity: large payments, many counterparties, or many networks.
- You hold USDT and want a regulated alternative in dollars. See USDT vs USDC for business.
Many companies hold both: USDC for dollar business, EURC for euro business, converting only when the currency of a payment changes. Each conversion between them carries an exchange rate, so convert in larger, planned amounts rather than payment by payment.
How this works with Align
Align supports EURC on Ethereum, Avalanche, Base and Solana, alongside USDC and USDT. You can receive EURC, convert it, and pay out euros over SEPA and SEPA Instant from a named EUR IBAN in your company's name, or dollars, pounds or dirhams from named USD, GBP and AED accounts. USDC to EUR explains the euro payout from USDC. Align is registered with FINTRAC in Canada as a money services business. It isn't authorized under MiCA, and this page is not an offer of crypto-asset services in the EU.

Common questions
- Is EURC MiCA compliant?
- Yes. EURC is issued by Circle Internet Financial Europe SAS, an electronic money institution authorized by France's ACPR, and qualifies as an e-money token under MiCA. USDC is issued in the EU by the same entity.
- Is EURC as safe as USDC?
- They have the same issuer, the same regulator and the same type of reserve rules, and Circle publishes monthly attestations for both. The practical differences are size and liquidity: USDC is far larger, so it's easier to convert in large amounts and accepted by more counterparties. In October 2026, the EBA classified USDC as a significant e-money token, which brings direct EBA supervision of its reserves from 12 November 2026.
- Which networks is EURC on?
- Circle lists EURC contracts on Arc, Avalanche, Base, Cronos, Ethereum, Plasma, Solana, Stellar and World Chain. Most EURC is on Ethereum, followed by Solana and Base. Always check which network your counterparty uses before sending.
- Can I earn interest on EURC or USDC?
- Not from the issuer, or from a crypto-asset service provider in the EU. MiCA's Article 50 bans issuers of e-money tokens, and crypto-asset service providers providing services related to them, from granting interest. Circle's white paper says the reserves can be held in interest-bearing instruments, but holders receive no interest.
