To maintain the existing user base, and improve the onboarding flow on the new chain, users must be able to seamlessly deposit ERC20 USDC to their dYdX account. By building the CCTP relayer for dYdX, dYdX will be accessible to both Cosmos and Ethereum based traders at no interruption of user experience. We expect this relayer to play a significant role in the launch of dYdX Chain.
