Circle has rolled out the Arc mainnet, where USDC is the native gas token for transaction fees. The project claims support for over 20 fiat-backed stablecoins and connectivity with more than 20 blockchains. The mainnet is already live, opening up new use cases for a stable settlement unit at the core infrastructure level.

USDC Gas Fees: Predictable Costs

Paying gas in USDC means users aren’t at the mercy of volatile native tokens for transaction fees. This makes it way easier to budget for operations and build financial models—devs and users can calculate costs in a stable unit, without having to hold extra volatile assets just to pay fees.

Stablecoin Support and Ecosystem Connectivity

With support for more than 20 fiat-backed stablecoins, Arc lets users settle in familiar currencies and smooths out friction for on-chain transactions. Connections to 20+ blockchains are all about cross-chain compatibility: apps and users get access to deeper liquidity and easier value transfers, no manual routing headaches required.

Real-World Impact for Devs and Businesses

Unified USDC fee calculations and cross-chain links streamline user flows, payment rails, and on-chain billing. For fintech and crypto services, this could mean lower operating costs and a simpler path to launching products across multiple chains, thanks to steady fees and broad stablecoin support.
