Arc as the default destination

Arc is Circle's stablecoin-native L1: sub-second finality and USDC as the native gas token. The Copilot defaults to consolidating idle USDC onto Arc, so your agent's "home base" never blocks on ETH gas.

Circle PaymasterUSDC-paid gas

Pay gas with USDC, not ETH

On Arc, USDC is the native gas token, so transactions never need ETH. On Arbitrum Sepolia, USDC Copilot routes execution through Circle's Paymaster (EIP-2612 permit + ERC-4337 bundler) so an agent's wallet only ever needs to hold USDC. No native-token funding loops, no gas surprises.
