Cardano Lands Native Support in Coinbase's x402 Payments Protocol

Cardano has made significant strides in its integration with Coinbase's x402 payments protocol. The Cardano Foundation engineers have contributed to the official x402 codebase, giving developers a standardized way to use the blockchain for internet-based payments.

The implementation brings Cardano directly into x402's reference tooling, allowing developers building applications around the open payments protocol to access Cardano using infrastructure similar to that available for other supported blockchain networks.

This integration provides client, server, and facilitator components alongside working examples. It supports Cardano mainnet as well as the preprod and preview environments, making it easier for developers to test applications before deploying them publicly.

Originally developed by Coinbase, x402 is an open payment protocol built around HTTP's '402 Payment Required' status code. It enables websites, applications, and autonomous AI agents to request and complete payments directly over the internet.
