Circle’s EURC sees $77M deposited across 20 DeFi venues as Aave V3 dominates

Circle’s euro-pegged stablecoin EURC has quietly amassed $76.6 million in deposits spread across 20 DeFi protocols. That’s not a massive number by USDC standards, but for a euro stablecoin operating in a market historically dominated by dollar-denominated assets, it represents a meaningful foothold.

The lion’s share of those deposits, roughly 70.9%, sits in Aave V3. That concentration tells you something about where the euro-denominated DeFi action is actually happening, and which protocol has managed to build the infrastructure that euro stablecoin users trust.

Aave V3’s outsized role

Aave V3 holds approximately $42.5 million to $42.7 million in EURC supply based on visible protocol snapshots. That means a single lending protocol accounts for more than two-thirds of all EURC deployed in DeFi.

The remaining 29% of EURC deposits are distributed across 19 other venues, including liquidity provision and foreign exchange trading pairs across multiple protocols.

The bigger EURC picture

The total circulating supply of EURC stands at approximately €410.6 million as of August 17, 2026. That means the $76.6 million sitting in DeFi protocols represents roughly 18-19% of the overall EURC supply depending on exchange rates.

Circle has positioned EURC as a fully reserved, 1:1 euro-pegged stablecoin with cash-equivalent redemptions. EURC currently lives across multiple blockchain networks: Ethereum, Base, Avalanche, Solana, and Stellar.

MiCA and the regulatory tailwind

Europe’s Markets in Crypto-Assets regulation, commonly known as MiCA, has created a framework that specifically addresses stablecoin issuance in the EU. MiCA’s requirements around reserves, transparency, and licensing have raised the barrier to entry for anyone wanting to issue a euro stablecoin.

For the broader DeFi market, dollar stablecoins like USDC and USDT still dominate global DeFi activity by an enormous margin. But within the European market specifically, compliant euro stablecoins are carving out territory for users and businesses that need to denominate transactions in euros for tax, accounting, or operational reasons.

What this means for DeFi’s euro market

When 71% of a stablecoin’s DeFi deposits sit in one protocol, any disruption to that protocol, whether technical, regulatory, or governance-related, would ripple through the entire EURC DeFi ecosystem. With EURC and USDC both issued by Circle and available across the same blockchain networks, the infrastructure also exists for on-chain forex trading between euros and dollars without touching centralized exchanges.
