Arc is an open Layer 1 blockchain from Circle, purpose-built for programmable money. USDC is the native gas token, so users never hold a separate asset to transact, and an EWMA-smoothed EIP-1559 fee market keeps costs near a cent. Malachite BFT consensus over a Proof-of-Authority validator set delivers deterministic finality in under a second, with no reorganizations to design around. The execution layer is Reth and targets the Osaka EVM baseline, so Solidity contracts and standard Ethereum tooling work unchanged.
