Cardano founder Charles Hoskinson has acknowledged the integration of the x402 protocol into the Cardano blockchain. The confirmation came in response to a post highlighting the x402 deployment alongside Masumi, a decentralized AI protocol built on Cardano. The announcement follows previous x402 partnerships with major exchanges Coinbase and Binance.
Masumi co-founder Patrick Tobler shared a demonstration of the x402 integration. The demo showed how web payments could trigger smart contract actions, such as minting tokens. The feature uses a simple interface where users send two USDM, Cardano’s USD-pegged stablecoin, and a small amount of ADA for fees. Tobler emphasized that the memecoin involved in the demonstration has no investment purpose and is solely for technical illustration.
x402 Enables Direct, Verifiable Payments for AI Agents
The x402 protocol allows native micropayments on the web without requiring sign-ins, emails, or complex authorization. It revives the HTTP 402 status code to facilitate instant access to services or APIs via small transactions. Through its integration with Cardano and Masumi, the protocol enables seamless, trust-based payment flows for AI agents interacting on-chain.

Masumi strengthens the x402 framework by offering trust layers such as identity management, decision logging, and refund mechanisms. These features ensure that AI agents engaging in economic activities on Cardano can transact with accountability. Tobler explained that x402 will work closely with Masumi’s smart contracts to create a secure foundation for future use cases in the AI payment economy.
Before the Cardano update, Binance Wallet added an x402-compatible list in its Markets tab. This list features assets and tokens aligned with the protocol’s payment standards. The integration aims to make Cardano a key financial infrastructure supporting AI-based automation and decentralized services.
