Interview with Quack AI CBO Rix: Introducing the Q402 Execution Layer — A New Standard for “Sign-to-Pay” On-Chain Transactions

In today’s blockchain ecosystem, every on-chain transaction still goes through a cumbersome process:Approve → Transfer → Pay Gas Fees.

This multi-step workflow not only limits large-scale adoption but also creates friction for enterprises and RWA platforms that require compliance, transparency, and operational efficiency.

To address this core pain point, on-chain governance AI protocol Quack AI has officially launched the Q402 Execution Layer — an infrastructure designed specifically for trustless, policy-aware on-chain payments. As a core component of Quack AI’s AI Autonomy Stack, Q402 is redefining how on-chain transactions are executed.

Being the first unified sign-to-pay execution and governance layer for the Agent Economy, Q402 is built on Quack AI’s strong ecosystem foundation. The project has already integrated with 40+ major blockchains, including BNB Chain, Linea, Polygon, and Base, and has issued over 7 million governance identities through its Governance Passport system, accumulating extensive real-world on-chain experience.

In July 2025, Quack AI raised $3.6 million in funding led by Animoca Brands, Kenetic Capital, and Merlin Chain. The funds are being used to accelerate Q402’s multi-chain expansion and improve developer tooling.

In this interview, Quack AI CBO Rix explains how Q402’s “Sign-to-Pay” model systematically addresses key challenges in compliance, auditability, and execution efficiency for on-chain transactions.

What Market Problems Does Q402 Solve?

Q: Can you introduce Quack AI and its role in the blockchain ecosystem?

Rix:
Quack AI is building the AI Autonomy Stack — an infrastructure layer that enables intelligent governance, compliance, and transactions across blockchains for agents, organizations, and protocols.

Our system is built on three core pillars:

1. Governance Intelligence – Bringing AI-driven decision-making and strategy automation to on-chain processes.
   
   

2. Q402 Execution Layer – Enabling trustless, policy-aware transactions across EVM networks.
   
   

3. RWA Infrastructure – Connecting verified real-world assets and institutions to compliant on-chain environments.
   
   

Together, these form the foundation of what we call Autonomous Governance where AI agents, users, and enterprises operate transparently and securely under predefined policy logic.
Q402 is the execution layer of this vision, turning governance and compliance rules into verifiable on-chain actions.

Q: What problem does Q402 address, and why did you build it?

Rix:
Today’s on-chain systems still rely on manual, multi-step transactions like “approve → transfer → pay gas.”

This limits scalability, creates user friction, and complicates compliance for institutions and RWA platforms that require transparency and auditability.

Q402 consolidates these fragmented steps into a single, verifiable workflow.
Users or agents sign once, gas is handled automatically, and every transaction follows programmable policy rules.

The result is a secure, policy-aware execution layer that makes autonomous payments practical across EVM networks.

Q: How does Q402 change things for enterprises and RWA platforms?

Rix:
Q402 provides a unified workflow for transactions that require traceability and compliance.

Teams can encode rules directly into the protocol instead of relying on manual approvals, backend scripts, or custodial sign-offs.

Each transaction becomes self-governing — it carries its own policy, executes autonomously, and is natively auditable.

This enables RWA operations, treasury management, and credit flows to be executed through a single, secure, traceable signature, without layered manual processes.

Q: How does Q402 solve compliance challenges in the RWA market?

Rix:
The RWA sector faces constant friction in verification, cross-jurisdiction compliance, and real-time reporting.

Q402 embeds verification and policy enforcement directly into the transaction flow.
Only compliant actions are executed, and audit data is permanently recorded on-chain.

This allows decentralized systems to meet institutional trust requirements without relying on external intermediaries.

How Does Q402 Work?

Q: What makes Q402 different from other payment protocols?

Rix:
Most systems focus on speed or wallet UX.
Q402 focuses on governed execution — every action must pass policy, verification, and traceability checks before settlement.

It doesn’t just process payments; it processes authorized intent backed by programmable governance.

This makes it suitable for both autonomous AI systems and regulated institutions that require built-in trust, transparency, and compliance.

Q: What does Q402’s architecture look like?

Rix:
Q402 connects authorization, execution, and verification into a unified framework with three layers:

1. Intent Layer – Captures structured transaction instructions from users, agents, or apps.
   
   

2. Execution Layer – A Facilitator executes the instruction, sponsors gas, and applies governance logic.
   
   

3. Verification Layer – Records results, policies, and audit data on-chain.
   
   

Q402 is live on BNB Chain.BNB Chain is the first network where Q402’s execution architecture is activated, demonstrating gasless, policy-aware execution in a high-throughput production environment.

Q402 is designed as a multichain execution layer, with BNB Chain serving as the initial live reference as the system expands to additional EVM networks.

Developers can integrate Q402 to enable single-signature payments, automated settlements, and agent-based interactions, all following the same verifiable standards.

Q: What technology enables secure, gasless execution?

Rix:Q402 is built on Ethereum standards, mainly EIP-7702 and EIP-712.

• EIP-7702 (Delegated Execution) allows users to authorize a Facilitator with a single signature to pay gas and execute complex transactions securely at the protocol level.
  
  

• EIP-712 (Structured Signatures) ensures users sign clearly defined intents and policy rules, not vague requests.

This guarantees trustless, policy-aware execution.

Q: What are the benefits for developers?

Rix:
Our BNB Chain deployment proves the advantages:

• Lower Development Cost: Q402 SDKs replace custom signing, gas sponsorship, and execution infrastructure.

• Universal ERC-20 Compatibility: Works with standard ERC-20 tokens without upgrades or new approval flows.

• Gasless Execution by Default: Transactions are executed through delegated, sponsored execution.

• Production-Grade Reliability: Live on BNB Chain with extremely low transaction failure rates.

• Faster Governance Settlement: Single sign-to-pay flows reduce governance settlement latency by over 70%.

• Agent-Ready Architecture: Q402 is designed for automated, policy-aware execution, making it suitable for agents and high-frequency systems.

Q: How does Q402 ensure security and compliance?

Rix:
Every transaction can be linked to verified identities through Governance Passports, with privacy protected by cryptography.

The Facilitator enforces transparent delegated execution, while optional compliance modules support KYC, jurisdiction filters, and policy-based restrictions.

Q402 works seamlessly in both permissionless ecosystems and regulated financial environments.

Q: What’s next on the roadmap?

Rix:

1. Standardize sign-to-pay execution with Q402
   Establish Q402 as the default execution layer on BNB Chain and expand support across additional EVM networks.
   
   

2. Strengthen agent intelligence and verification
   Introduce reasoning proofs, guarded execution, and agent-to-agent coordination to make autonomous actions explainable and enforceable.
   
   

3. Enable simulation before execution
   Launch simulation and sandbox environments so protocols can test governance, treasury, and market strategies before deploying capital on-chain.
   
   

4. Advance intelligent treasury operations
   Roll out autonomous, policy-aware treasury agents with real-time monitoring, analytics, and cooperative execution models.
   
   

5. Unify the Agent Economy
   Deploy Q402 Mainnet v2 with adaptive policy learning, cross-agent coordination, and a shared execution registry spanning multiple protocols and chains.

Q: What is the long-term vision?

Rix:

The long-term vision is to make Q402 the default execution layer for on-chain systems.

We’re moving toward a world where transactions, payments, and automated actions are authorized through one intelligent, policy-bound signature, regardless of chain, asset, or application.

Q402 will continue to evolve beyond basic execution into:

• Smarter, policy-aware sign-to-pay flows

• Agent-driven execution that adapts to real-time conditions

• Verifiable, auditable action at system scale
  
  

As agents, applications, and institutions operate on-chain, Q402 becomes the invisible execution infrastructure that turns intent into action.

Safely, automatically, and across networks.
