Cardano joins x402 standard to enable AI agent payments with ADA tokens

Cardano has been integrated into the x402 software kit, allowing developers to build apps and AI agents that can pay for online services using ADA or Cardano-issued tokens. The x402 standard automates pay-per-use transactions within internet requests, removing the need for accounts or subscriptions. Cardano's implementation has completed a transaction on a pre-production network but has yet to operate on the mainnet or demonstrate large-scale commercial payments. This move puts Cardano alongside Solana and XRP Ledger in the emerging market for machine-driven payments using blockchain assets.

As of Sep 22, 2026 11:31 WIB, Cardano's ADA is trading at Rp4.454 on Pluang, showing a strong 1-day gain of 8.63%. This positive momentum contrasts with Solana's SOL, which is priced at Rp2.080.957 with a 1-day increase of 5.16%. Cardano's market cap stands at Rp162,33 trillion, reflecting notable investor interest as it joins Solana and XRP Ledger in advancing AI agent payment technologies.
