The issuer of the second-largest stablecoin USDC, with a market value of 77 billion USD, Circle, has announced the launch of its Layer-1 blockchain Arc. Arc is designed as a 'stablecoin blockchain' aimed at addressing commercial challenges such as transaction fee volatility and privacy by using USDC as gas fees, achieving sub-second finality, and providing optional privacy features. This EVM-compatible blockchain will have its own token, and Circle positions it as a significant opportunity in the cryptocurrency space by 2026, focusing on efficient and large-scale stablecoin transfers.
