Introducing CSPR402, an x402-inspired payment protocol built on @Casper_Network. It lets an AI agent create an order, pay with native $CSPR on Casper mainnet, and receive a simulated virtual card only after the backend verifies the on-chain deploy.

We placed 2nd at the @Casper_Network Agentic Buildathon 2026! 🥈 CSPR402 lets an AI agent make one verified on-chain CSPR transfer and get a virtual card back — no custodial wallet in between. Huge thanks to Casper for this and giving builders the stage.
