OKX and Circle are enabling USDC transactions without network fees and integrating the OKX DEX aggregator with Circle’s Cross-Chain Transfer Protocol (CCTP). The 'USDC Zero Network Fee Campaign' enables OKX Wallet's Smart Account users to conduct USDC transactions without network fees from September 7 to October 5, 2023, with further details available here. OKX Wallet's Smart Account feature, powered by account abstraction technology and launched on August 2, 2023, enables seamless transactions across multiple blockchains using stablecoins like USDC. The integration of the OKX DEX aggregator with Circle’s CCTP, a permissionless on-chain utility that enables USDC to move natively between blockchains, provides a more streamlined experience for users trading USDC pairs. As new CCTP routes become available, the OKX DEX aggregator is expected to support additional blockchains for USDC cross-chain functionality.
