91.5% of Euro Stablecoins Concentrated on Three Blockchains

91.5% of the euro stablecoin market is concentrated on three blockchains: Ethereum (ETH), Solana (SOL), and Base, according to Crypto Briefing's mid-August 2026 report. The market size expanded from approximately €50 million in early 2024 to $835 million by mid-August 2026.

Ethereum holds a 69.5% share, with an estimated supply of $579 million to $589 million (approximately ¥77.76 billion to ¥79.1 billion). Solana accounts for about 14.8%, while Base, Coinbase's Ethereum Layer-2 network, holds around 6.9%. The combined market share of these three networks totals 91.5%.

Other blockchains supporting euro stablecoins include Gnosis, XRP Ledger, BNB Chain, and Avalanche (AVAX), among approximately 17 networks, collectively holding less than 9% of the market.

Issuers also show concentration: EURC holds up to 63% of total supply, with EURCV from Societe Generale's SG Pay contributing significantly. Combined, these two issuers account for over 80% of the euro stablecoin supply.

Regulatory compliance affects market size calculations. MiCA-compliant euro stablecoins grew from $295.6 million in June 2025 to $673.9 million by June 2026, a 128% increase. However, Crypto Briefing's reported figure of $835 million includes all euro-stablecoin markets, not just MiCA-compliant ones.
