Settled in under a second
Built on Arc, Circle's L1 for stablecoin finance. Deterministic finality means a payment is final the moment it lands - no confirmations, no reorgs, no reversals.
One asset for everything
USDC is Arc's native gas token. The balance you send from also pays the ~$0.01 fee. No ETH, no wrapping, no second token to manage - ever.
A complete payment toolkit
Send with on-chain memos, request with links and QR codes, batch-pay 100 people at once, run subscriptions, and issue refunds - plus an SDK to accept USDC on any website.
