Cardano has integrated into the x402 software kit, enabling AI payments using ADA, competing with Solana and XRP Ledger.
Cardano's integration into the x402 software kit positions it to compete in AI payment solutions.
Cardano has been officially integrated into the x402 software kit, allowing developers to create applications and AI agents that can utilize ADA and other tokens from the Cardano network for online service payments. This move places Cardano in direct competition with Solana and the XRP Ledger in the rapidly evolving landscape of machine payments.
The x402 standard revolutionizes the rarely used "402 Payment Required" HTTP response into a streamlined checkout process via internet requests. This allows AI agents to sign transactions and acquire necessary data or computational resources without requiring users to create accounts or input credit card details.
For instance, an AI agent generating reports can promptly purchase specific datasets, simplifying the transaction process for users.
Originally developed by Coinbase in 2025, the x402 standard has since transitioned to an organization supported by the Linux Foundation, with participation from major players like Visa, Mastercard, Stripe, Google, and Amazon Web Services. It is already supported by multiple networks, including Solana and the XRP Ledger.
Cardano's engineers built their implementation of the x402 standard based on a specification approved in June, creating the necessary client and server software to facilitate these transactions. Currently, the software supports TypeScript, with plans for future compatibility with Python.
While successful transactions have been completed on Cardano's pre-production network, the technology has yet to be deployed on the mainnet for large-scale commercial use. Developers can begin integrating Cardano into their projects, but as of now, there are no examples of commercial transactions occurring at scale using ADA.
With this integration, Cardano aims to enhance its presence in the AI payments sector, vying for adoption alongside Solana and the XRP Ledger as developers explore machine payment solutions.
