According to CoinMeta, Kite and Circle are collaborating to explore service transactions based on the Arc mainnet, covering service discovery, quoting, transaction agreements, delivery and acceptance, as well as USDC payment and settlement. Kite constructs the transaction process through Kite Seller Console and Kite Agent Passport, responsible for service agreements and delivery, while Arc provides the payment and settlement network. The relevant processes have been verified on the Arc test network.
