EURC is a digital euro issued by Circle, backed 1:1 by real euros. Here's how it works, why it exists, and what Europeans should know before holding it.
EURC is a digital euro issued by Circle, the American fintech behind USDC. Every EURC in circulation is backed 1:1 by real euros held in regulated financial institutions. It moves across the internet in seconds, works 24/7, and is increasingly accepted as the European equivalent of holding dollars on-chain.
If you've read our plain-English guide to stablecoins, you'll already know the general idea: a stablecoin is a digital version of a currency, backed by real reserves, that moves on public blockchains at internet speed. This article zooms in on one specific stablecoin - EURC - because it's the euro stablecoin most relevant to Europeans today, and it's the one Defied is built around.
By the end of this article, you'll know what EURC is, who issues it, how it stays pegged to the euro, how it's regulated in Europe, and what the real risks are. No jargon. No marketing spin.
The 60-second answer
EURC is a digital token that represents one euro. Each EURC is backed by one euro (or one euro's worth of very short-term, extremely safe investments) held in regulated financial institutions.
It's issued by Circle Internet Financial - the same US-based company that issues USDC, the second-largest dollar stablecoin in the world. EURC launched in 2022, and by 2026 it had become the largest and most-used euro stablecoin on public blockchains.
You can hold EURC, send it, receive it, and convert it back to regular euros whenever you want - 24/7, globally, without the intermediaries that make traditional bank transfers slow and expensive.
Why EURC exists
By the time EURC launched, stablecoins had already proven themselves useful - but almost all the liquidity was in US dollars. USDC and USDT together represented over 95% of the stablecoin market. Europeans who wanted to move money on blockchain rails were forced to hold dollars, which exposed them to EUR/USD exchange rate fluctuations on every transaction.
Circle saw the gap and issued a euro-denominated equivalent. The logic was simple: a European holding euros should be able to have a digital version that tracks the euro, not the dollar. A European business paying a French supplier shouldn't have to convert through USD just because that's where the liquidity is.
EURC filled that gap. It's functionally identical to USDC - just denominated in euros instead of dollars, with reserves held in euro-denominated assets rather than dollar-denominated ones.
How EURC actually works
EURC is a fiat-backed stablecoin. Here's what that means in practice:
Step 1: A user wants to hold EURC. Either through an exchange or through a regulated partner, the user deposits euros. Circle mints new EURC tokens in an amount equal to the euros received, and those tokens arrive in the user's blockchain wallet.
Step 2: The euros go into reserves. The cash used to mint EURC is held by Circle in regulated financial institutions - either as cash in bank accounts or invested in very short-term, highly liquid instruments like European government treasury bills. The goal is that every EURC in existence has a matching euro sitting in reserve.
Step 3: EURC moves on blockchains. Once minted, EURC exists on public blockchains - currently Ethereum, Base, Avalanche, Solana, and Stellar. It can be sent between any two addresses on those networks, typically in seconds, for a small network fee (often cents or less on networks like Base).
Step 4: Redemption burns the tokens. When a user wants to convert EURC back to regular euros, they send the tokens to Circle (or a regulated partner), who burns them - removing them from circulation - and sends the equivalent euros to the user's bank account.
The total supply of EURC on-chain is always visible. The total reserves are attested to monthly. Anyone can verify that the two numbers match.
Who is Circle, and why does it matter?
EURC's credibility depends entirely on the company issuing it. So it's worth knowing who Circle is.
Circle Internet Financial is a US-based fintech company founded in 2013. Its headquarters are in Boston, Massachusetts. Circle issues several regulated digital currencies, most notably USDC (dollar) and EURC (euro), and operates under a combination of US money transmitter licenses, a New York BitLicense, and - relevant to European users - authorisation as an Electronic Money Institution under EU regulations.
This matters for two reasons:
Regulated issuer. Unlike some stablecoin issuers, Circle operates under clear financial regulation in multiple jurisdictions. Reserves are audited. The company can't simply disappear overnight without leaving a public regulatory trail.
Public transparency. Circle publishes its reserve composition monthly and reports regularly on the total supply of its stablecoins in circulation. This is a higher standard of transparency than many private crypto companies offer.
Circle is among the most regulated and scrutinised stablecoin issuers in the world today. That's not a guarantee of safety, but it meaningfully reduces certain categories of risk.
The reserves - how you know each EURC is backed
This is the question that matters most for trust: how do you actually know each EURC is backed by a real euro?
Circle publishes monthly attestation reports through an independent auditor (historically Deloitte). These reports verify:
- The total supply of EURC in circulation as of a specific date - The total value of reserves held to back that supply - The composition of those reserves - how much is cash, how much is government securities, and where they're held
The reports are published on Circle's transparency page and are free to read.
What you're actually getting in these reports is an attestation - an independent verification of specific facts at a specific moment - rather than a full financial audit. That's a meaningful distinction. An attestation confirms the reserves existed at the time of the snapshot. It doesn't provide the same depth of ongoing scrutiny as a full audit. For most users, monthly attestations by a major accountancy firm are sufficient assurance. For more cautious users, it's one piece of evidence among several.
EURC and European regulation
Under the EU's Markets in Crypto-Assets Regulation (MiCA), euro-denominated stablecoins are classified as E-Money Tokens (EMTs). The rules for EMTs became applicable on 30 June 2024 - six months before the broader MiCA rules took effect.
To issue an EMT in the EU, a stablecoin issuer must:
- Be authorised as an Electronic Money Institution (EMI) or credit institution in an EU member state - Hold reserves in highly liquid, low-risk assets - Publish a white paper describing the token and its backing - Grant holders a right of redemption at par value - Comply with specific marketing and disclosure rules
EURC is compliant with these requirements. Circle operates under EMI authorisation in France, granted by the ACPR (the French banking and insurance supervisor), which gives it the legal basis to issue EURC to European users.
This is significant. Not every stablecoin available in the EU is MiCA-compliant. Some have been delisted from European exchanges for failing to meet the new standards. EURC has not only remained available but has grown significantly because it was designed from the outset to fit European regulation.
For European users, this means EURC is among the most regulated stablecoins available. That doesn't make it risk-free - we'll cover that below - but it means the issuer is operating under clear rules with active oversight.
EURC vs other euro stablecoins
EURC isn't the only euro stablecoin. A few alternatives exist, each with different trade-offs.
EURe (Monerium) - Issued by Monerium, a licensed Electronic Money Institution in Iceland (EEA). Notably, EURe holders can redeem directly to a bank account via SEPA transfer - the token is treated as regulated electronic money. Smaller market cap than EURC, but with direct banking rail integration.
EURS (Stasis) - One of the first euro stablecoins, issued by Stasis. Backed by euro reserves, but smaller in circulation than EURC and less widely integrated across DeFi.
EURI (Eurite) - Issued by Banking Circle, a European payments bank. MiCA-compliant. Smaller market presence but growing.
EURA (Angle) - A decentralised euro stablecoin backed by crypto collateral rather than bank-held euros. Appeals to users who prefer decentralisation over regulatory integration, but has different risk characteristics than fiat-backed alternatives.
For most European users today, EURC is the default choice. It has the deepest liquidity, the widest exchange support, the clearest regulatory status, and the most recognisable issuer. That's why Defied is built around it.
That said, EURe (Monerium) deserves mention because it has one unique property: it's issued as regulated electronic money, not as a classical stablecoin. This means EURe holders have a direct legal claim to the underlying euros, redeemable via SEPA - a slightly stronger consumer protection framework than a pure fiat-backed stablecoin.
What you can actually do with EURC
Holding EURC in a wallet gives you several capabilities that holding euros in a bank doesn't:
Send globally in seconds. Transfer EURC to any wallet address, anywhere in the world, 24 hours a day. No SWIFT codes, no banking hours, no €25 wire fees. A typical transfer on Base costs a few cents in network fees and settles in under a minute.
Earn yield through lending markets. By depositing EURC into open, on-chain lending markets like Aave, you can earn interest while borrowers take liquidity. Current rates on EURC typically run between 3% and 5% annually, depending on market conditions. This is directly accessible to anyone holding EURC.
Exchange for other stablecoins. Switch between EURC and USDC (or other stablecoins) instantly, at transparent rates, with small fees. Useful for anyone receiving payment in one currency and spending in another.
Spend with a card. Several providers - including Gnosis Pay - offer Visa debit cards that spend from stablecoin balances. The conversion happens at the point of sale.
Hold as savings without bank dependency. For Europeans concerned about account freezing or banking system fragility, holding EURC in a non-custodial wallet provides a parallel savings mechanism that doesn't depend on any single bank or fintech continuing to operate.
The real risks
No article about a financial product is complete without an honest discussion of risks. Here are the ones that actually matter.
Issuer risk. EURC is only as trustworthy as Circle. If Circle failed - through fraud, mismanagement, or insolvency - EURC could briefly lose its peg or become temporarily unredeemable. The probability of this is low (Circle is regulated, public, and audited), but it isn't zero. This is the main reason monthly attestations matter.
Reserve bank risk. Circle holds EURC reserves in regulated financial institutions. If one of those banks failed, a portion of reserves could be at risk. In practice, reserves are diversified across multiple institutions specifically to limit this exposure.
Regulatory risk. MiCA is still a young framework. New rules or interpretations could affect EURC's availability, features, or accessibility for certain users. The direction of European regulation is broadly supportive of regulated stablecoins like EURC, but changes are possible.
Smart contract risk. EURC is a smart contract on several blockchains. While Circle's smart contracts are audited, no audited contract is ever provably bug-free. This is a low-probability but real risk.
Depeg risk. In extreme market stress, EURC could briefly trade slightly above or below €1 on secondary markets. In 2023, USDC briefly depegged to around $0.87 during the Silicon Valley Bank crisis before recovering fully. EURC is exposed to similar market dynamics under similar circumstances.
No deposit guarantee scheme. Unlike euros held in a regulated European bank, EURC is not protected by the EU's €100,000 deposit guarantee scheme. It's a different product with different protections. Read our full risk disclosure before holding significant amounts.
Common questions
Is EURC legal tender? No. Only euros issued by the European Central Bank are legal tender. EURC is a digital representation of the euro, redeemable 1:1, but it's a private instrument.
Can anyone hold EURC? In principle, yes - anyone with a compatible wallet can hold EURC. To acquire it through regulated channels (exchanges, fintech apps), you'll typically need identity verification.
Is EURC the same as a digital euro? No. The European Central Bank is developing a "digital euro" - a central bank digital currency (CBDC) - as a separate project. The digital euro, if launched, would be issued by the ECB itself. EURC is issued by a private company (Circle) under regulatory authorisation. Both could coexist.
Can I lose my EURC? Yes, in specific circumstances: if you lose access to the wallet holding it, if someone gains access to your wallet, or in the extremely rare case of a protocol or issuer failure. Storing EURC in a non-custodial wallet means you're responsible for its security.
How is EURC taxed? Treatment varies by country. In most EU jurisdictions, EURC itself is not a taxable asset in the same way investments are - but yield earned on EURC, or gains from converting between EURC and other assets, may be taxable. Consult a tax advisor familiar with your jurisdiction.
Why Defied is built on EURC
We built Defied around EURC because it's the most practical euro stablecoin for European users today. It's issued by the most regulated, publicly listed stablecoin issuer. It has the deepest liquidity across major on-chain lending markets. It's compliant with MiCA. And it's native to Base, the Ethereum Layer 2 we use for speed and low fees.
For a European saver who wants a euro-denominated account that works across the internet - one that earns yield, moves in seconds, and can't be frozen - EURC is the natural building block. Defied is the interface that makes it practical.
