Cardano joins x402 toolkit for AI agent payments

The official x402 toolkit now includes Cardano tools, letting apps and AI agents pay with ADA and other network tokens. The integration places Cardano alongside Solana and the XRP Ledger in the race to standardize how autonomous agents settle automated payments.

• Tooling lets agents pay on-cardano with native network tokens.
• The facilitator has so far only been tested on pre-production, so broad production readiness is not yet confirmed.
