Arc is a Layer 1 blockchain built by Circle , the company behind USDC purpose-built for stablecoin payments and institutional finance. Unlike general-purpose chains, Arc is designed around stablecoins as the unit of account: it's EVM-compatible, uses USDC as the gas token for predictable fees, and offers sub-second settlement, optional privacy, and quantum-resistant security at launch. Circle frames it as an "operating system" for the on-chain economy, not just payments.
The institutional signal here is unusually strong. Arc's $222M token presale drew a syndicate that reads like a who's-who of traditional finance ,a16z crypto (lead, $75M), BlackRock, Apollo, Intercontinental Exchange (NYSE's parent), ARK Invest, and Standard Chartered Ventures among them at a $3B fully diluted valuation. Its testnet has processed over 244 million transactions ahead of a mainnet expected sometime in 2026.
