The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending USDC ERC20, and that one goes to the blockchain, not to us.

What lands at your address	USDT in Arbitrum One	The same stablecoin; turning USDT into USDC is a separate step
Wallet and signatures	Not needed: the coins go to the address from the order	Needed: connect the wallet and sign contract transactions
A coin for fees in Arbitrum One	Not needed to receive	Often needed, or the funds cannot be claimed or moved on
Timing	After confirmations in Ethereum; the order page tracks it	Depends on the bridge and the load of both networks
