Chains
Coven bridges USDC between Arc and ten chains, in both directions, using Circle’s CCTP with the Forwarding Service.

Arc itself is domain 26.
coven.bridge.chains()// [{ chainId, name, domain, usdc, gasless }, ...]“Gasless deposits” means Circle Paymaster runs there, so a user with USDC and no native token can still pay for the transfer into Arc. See gasless deposits.
How long transfers take
Section titled “How long transfers take”Fast transfers settle in seconds to a few minutes and pay a small Circle fee. Standard transfers wait for full finality on the source chain, which is quick on most chains and around fifteen minutes on Ethereum, and pay no Circle transfer fee. Both pay the forwarding fee, roughly two cents, for delivery on the far side.
Swapping and bridging together
Section titled “Swapping and bridging together”Leaving Arc, a swap into USDC and the bridge happen in one transaction. Arriving, the USDC lands on Arc where it also pays for gas, so a swap right after costs nothing extra to set up.
