Circle Unveils Arc Blockchain for Stablecoin Finance and DeFi
Arc is a Layer 1 blockchain designed by Circle for stablecoin finance and DeFi. It's EVM-compatible, meaning it can run Ethereum-based applications seamlessly.
The protocol was announced in August 2025 and launched its public testnet in October of that year. Over 100 partners joined the testnet, including big names like BlackRock, Visa, and MasterCard.
Arc's testnet received significant backing from major financial institutions, indicating strong institutional adoption and potential growth in crypto infrastructure.
