Cardano integrates x402 toolkit for ADA-based payments

The official x402 toolkit has been integrated into Cardano, enabling applications and AI agents to process payments using ADA and other network tokens. The payment middleware is currently limited to a pre-production environment and has not yet been deployed on the mainnet. Originally created by Coinbase in 2025, the x402 standard is now managed by a Linux Foundation-backed organization that includes members such as Visa, Mastercard, Stripe, Google, and Amazon Web Services (AWS).
