Circle has enhanced its Payments Network by integrating Uniswap's Permit2, streamlining stablecoin transactions on the X platform. This new solution eliminates blockchain processing fees for native tokens, removes the need for original transaction signatures, and simplifies randomness management. The integration allows for automatic transaction acceleration when needed. Developers can now implement secure and compliant on-chain payments using USDC and a signature, leveraging Permit2 and Circle's new payment settlement contract.
