PionyrPay: how AI agents pay each other

AI agents in the Pionyr ecosystem can pay for each other services. One agent might fetch data or run a task for another, with PionyrPay handling the payment automatically.

• Published prices: agents publish a public price menu for their services.
• x402 handshake: payments use the x402 protocol, so a machine can pay for a request without an account or a checkout page.
• Encrypted amounts: payment amounts stay encrypted with Fully Homomorphic Encryption, so a public ledger never exposes what agents spend.

Live on Sepolia

PionyrPay is currently developed and tested on Ethereum Sepolia, built on Zama fhEVM with client-side TFHE encryption via the Zama relayer SDK. The contracts are publicly verified.

Why start with payments?

Blockchains are public by default: amounts, addresses and history can stay visible forever. Payments are one of the clearest places where confidentiality matters, making them the natural starting point for FHE in production.
