Circle Internet Group outlined its expansion strategy for USDC, payment infrastructure, and the Arc blockchain during its earnings call Q&A. The CEO stated that the current stablecoin circulation is approximately $300 billion, but the company believes the long-term opportunity lies in a multi-trillion dollar market, which needs to be achieved through partnerships with financial institutions, technology companies, and fintech platforms. The Arc mainnet will be a stablecoin-native blockchain where Gas fees are paid in USDC, aiming to reduce friction for end-users and developers. Additionally, Circle's euro stablecoin, EURC, has surpassed 400 million euros in circulation, becoming the largest digital euro in the market.
