Circle Unveils Arc Blockchain for Global Payments and Tokenized Markets

Circle has launched Arc, its public mainnet, expanding beyond its USDC stablecoin business to support payments, tokenized assets, and financial markets worldwide.

Arc is a Layer 1 blockchain designed for real-time money movement and financial applications, using USDC as native gas. The network supports deterministic sub-second finality, allowing transactions to reach final settlement quickly.

Circle operates the network with a permissioned group of institutional validators and has processed over 700 million transactions on its testnet before the public mainnet release.
