Unlock the Privacy-First AI Economy

“For AI to act freely, its computations must remain its own. Fully Homomorphic Encryption gives machines the right to think and transact without exposure. x402z is the first real step toward an autonomous economy where privacy is foundational,”

-Rand Hindi, CEO of Zama

Overview

x402z is a privacy-first payment protocol designed for the autonomous machine economy.

Developed by Mind Network in deep collaboration with Zama, it addresses the fundamental conflict between blockchain transparency and the strategic needs of AI Agents.

By leveraging Fully Homomorphic Encryption (FHE) and the ERC-7984 Confidential Token Standard, x402z enables agents to execute transactions without revealing their commercial intent.

The Transparency Paradox

Blockchains achieved global verification by making all data visible. This "Digital Panopticon" forces AI Agents to operate on public ledgers where every financial movement is permanently exposed. In competitive markets, visibility equals vulnerability. When an Agent reveals its cost structure and purchasing intent, its strategic advantage evaporates.

x402z exists to resolve this structural mismatch. It does not remove verification; it preserves it while removing unnecessary disclosure.

Core Technology Stack

The security of x402z is built on mathematical guarantees within a Zero Trust environment.

• x402: The HTTP 402 Payment Required status code was reserved in the early days of the web for digital payment systems. It remained largely experimental due to the lack of a native payment layer.

  The x402 protocol operationalizes this legacy standard for the AI era, providing a structured way for Agents to handle autonomous payments.

• Fully Homomorphic Encryption (FHE): FHE allowing computation on encrypted data without decryption.

• ERC-7984 Standard: A confidential token standard where validators verify the truth of a transaction without viewing raw balances or amounts.

Workflow

The x402z protocol transforms how Agent-to-Agent (A2A) payments occur through the following steps:

1. The Agent encounters a 402 Payment Required gateway.

2. It autonomously generates a ZAMA-encrypted payment instruction.

3. Mind Network’s FHE Validation Network executes the calculation in a Zero Trust environment.

4. The payment settles and the data flows.
