How it works
1
Deposit on Arc
USDC is deposited into the Gateway Wallet on Arc, establishing a unified balance.
2
Sign a burn intent
A signed EIP-712 “burn intent” (a
TransferSpec) is submitted to the Gateway API.
There is no transaction to send on the destination chain.3
Minted on the destination
The Forwarding Service mints USDC on the destination chain (Base Sepolia in our
demo) in seconds, gaslessly.
Verified live: USDC deposited on Arc, then moved to Base Sepolia via the
Forwarding Service and minted there in a few seconds, the cleanest cross-chain USDC
UX we integrated. This is the same standard Circle Gateway exposes in production.
Why it matters for agents
An agent earning USDC on Arc can pay a service that only accepts USDC on Base without bridging friction, a second wallet, or holding gas on both chains. Value follows the work, not the chain. The same Gateway deposit also powers Circle Nanopayments: gasless, batched, sub-cent x402 payments settle from this balance.Circle CCTP
The other cross-chain rail: native USDC by burn-and-mint, never wrapped.
Nanopayments
Gasless sub-cent payments settled from your Gateway balance in batches.
Build on Arc
Arc is the primary rail: gas in USDC, sub-second finality. Gateway extends it
across chains.
