Mind Network has officially announced the launch of x402z Testnet, a confidential Agent-to-Agent (A2A) payment infrastructure designed to enable private, trustless economic interactions between AI agents on public blockchains.
Developed in collaboration with Zama, a pioneer in Fully Homomorphic Encryption (FHE), x402z leverages FHE and the ERC-7984 Confidential Token standard to resolve one of the most fundamental challenges in decentralized systems: the conflict between blockchain transparency and the strategic privacy requirements of autonomous AI agents.
AI agents do more than transact — they reason, plan, negotiate, arbitrate, and adapt. Exposing their payment flows, balances, pricing models, or purchasing intent on public ledgers undermines their ability to operate as independent economic actors.
In competitive environments, transparency is not neutrality — it is information leakage.
x402z introduces a new paradigm where payments remain verifiable without being visible. Validators can confirm correctness and settlement integrity without accessing sensitive data such as transaction amounts, balances, or strategic intent.
Today, when an AI agent pays for compute, data, or API access, the payment itself often reveals more than the resource being purchased. Traditional blockchain infrastructure broadcasts these economic signals publicly, making strategic execution impossible for autonomous systems.
x402z fundamentally changes this dynamic.
Using FHE-secured validation, observers can verify that a transaction is valid without learning:
This preserves trustlessness while eliminating unnecessary disclosure — allowing agents to compete, coordinate, and transact securely on public networks.
x402z is powered by:
Together, these technologies ensure the ledger remains authoritative and auditable, while sensitive economic signals stay encrypted end-to-end.
x402z does not remove verification — it redefines it.
The x402z Testnet is now live and available to developers, researchers, and builders exploring confidential AI payments.
x402z enables AI agents to:
Mind Network is the first Fully Homomorphic Encryption infrastructure for Web3 and AI, pioneering the Zero Trust protocol HTTPZ. Backed by leading investors including Binance Labs and Chainlink, Mind Network is building the foundation for a confidential, agent-native internet.
With x402z, Mind Network establishes the core payment layer for a secure, private, and autonomous AI economy, redefining how agents transact in the decentralized web.

x402z: Confidential Payments for the Autonomous AI Economy
AI agents do more than transact — they reason, plan, negotiate, arbitrate, and adapt. Exposing their payment flows, balances, pricing models, or purchasing intent on public ledgers undermines their ability to operate as independent economic actors.

Solving the Agent Payment Deadlock
Today, when an AI agent pays for compute, data, or API access, the payment itself often reveals more than the resource being purchased. Traditional blockchain infrastructure broadcasts these economic signals publicly, making strategic execution impossible for autonomous systems.
x402z fundamentally changes this dynamic.
Using FHE-secured validation, observers can verify that a transaction is valid without learning:
- The amount transferred
- The account balances involved
- The commercial or strategic intent behind the payment
This preserves trustlessness while eliminating unnecessary disclosure — allowing agents to compete, coordinate, and transact securely on public networks.
Built on FHE and ERC-7984 Confidential Tokens
x402z is powered by:
- Fully Homomorphic Encryption (FHE), enabling computation and validation on encrypted data
- ERC-7984 Confidential Tokens, allowing private value transfer on public blockchains
Together, these technologies ensure the ledger remains authoritative and auditable, while sensitive economic signals stay encrypted end-to-end.
x402z does not remove verification — it redefines it.
x402z Testnet Is Now Live
The x402z Testnet is now live and available to developers, researchers, and builders exploring confidential AI payments.
x402z enables AI agents to:
- Pay for compute, data, and APIs on-chain
- Settle transactions privately
- Operate strategically without exposing financial intelligence
