Guest: Rix, Quack AI CBO
Interview organized by: momo, ChainCatcher
In the current blockchain world, completing an on-chain transaction still feels like a series of hurdles: first authorization, then transfer, and finally, a separate payment of Gas fees. This fragmented operation not only slows down the pace of large-scale applications but also causes headaches for enterprises and real-world asset (RWA) platforms that prioritize compliance, transparency, and efficiency.
Targeting this core pain point, the AI protocol Quack AI, focused on on-chain governance, has officially launched the Q402 execution layer. This is an infrastructure born for "trustless, strategy-aware" on-chain payments and is a core component of Quack AI's "AI autonomous stack." The emergence of Q402 aims to reshape the execution logic of on-chain transactions.
Q402 claims to be the first execution and governance layer in the agent economy to achieve unified "signature equals payment." As of now, it has integrated over 40 mainstream public chains, including BNB Chain, Linea, Polygon, and Base, and has issued over 7 million on-chain identities through its innovative "governance passport" system, accumulating rich practical experience in real business scenarios.
In July 2025, Quack AI completed a $3.6 million financing round led by Animoca Brands, Kenetic Capital, and Merlin Chain. This funding has been fully invested in the multi-chain ecosystem expansion and developer tool enhancement of Q402.
In this interview, we spoke with Quack AI's Chief Business Officer Rix, who provided an in-depth interpretation of how Q402 systematically addresses the key challenges of compliance, auditability, and execution efficiency in on-chain transactions through the "signature equals payment" model.
What market pain points does Q402 target?
1. ChainCatcher: Could you introduce Quack AI and its role in the ecosystem?
Rix: Quack AI is building an "AI autonomous stack." In simple terms, it is a set of infrastructure that provides intelligent governance, compliance checks, and transactions across blockchains for agents, organizations, and protocols.
This system is supported by three core pillars:
Governance Intelligence: Bringing AI-driven decision-making and strategy automation on-chain.
Q402 Execution Layer: Achieving transactions that require no trust in third parties and can perceive strategies within EVM networks.
RWA Infrastructure: Securely and compliantly connecting verified real-world assets and institutions to the blockchain.
Together, these three components form the foundation of what we call "autonomous governance." Here, AI agents, users, and enterprises can operate transparently and securely under predefined strategic logic. Q402 is the "execution engine" that turns governance and compliance rules into verifiable on-chain actions.
2. ChainCatcher: Why create Q402? What problems does it solve?
Rix: To be frank, most on-chain systems today still use that old-fashioned, manual multi-step process of "authorization-transfer-pay Gas." This directly limits scalability, creates friction in user experience, and complicates compliance for institutions and RWA platforms that require transparency and auditability.
The idea behind Q402 is straightforward: to integrate these fragmented steps into a single, verifiable workflow. Users or agents only need to sign once, and the system automatically handles the Gas fees, ensuring that every transaction adheres to the established strategic rules. Ultimately, we have created a secure and strategy-aware execution layer that makes autonomous payments truly feasible within EVM networks.
3. ChainCatcher: What does this mean for enterprises and RWA platforms?
Rix: The change is significant. Q402 provides a unified workflow for transactions that require traceability and compliance. Teams can now write rules directly into the protocol without relying on cumbersome manual approvals, backend scripts, or custodial signatures.
Every transaction inherently possesses governance capabilities. It carries its own strategy, executes itself, and is inherently auditable. This means that whether it's RWA operations, fund management, or credit circulation, everything can be completed through a single secure, traceable signature, eliminating the layers of manual processes.
4. ChainCatcher: How does Q402 specifically address compliance challenges in the RWA market?
Rix: The RWA sector has long faced challenges with verification, cross-jurisdiction compliance, and real-time reporting. Q402 addresses this by embedding verification and strategy execution directly into the transaction flow. Only actions that comply with the strategy will be executed, and all audit data will be permanently recorded on-chain. This allows decentralized systems to meet institutional-level trust requirements without relying on external intermediaries.
How does Q402 work?
5. ChainCatcher: What makes Q402 unique compared to other payment protocols?
Rix: Many systems focus on speed or wallet experience. The core of Q402 is "governed execution"—every action must pass through strategy, verification, and traceability checks before finalization. We are not just handling payments; we are dealing with "authorization intent" backed by programmable governance. This makes it suitable for autonomous AI systems and perfectly fits regulated institutions that require built-in trust, transparency, and compliance.
6. ChainCatcher: Can you briefly explain the architecture of Q402?
Rix: Q402 unifies authorization, execution, and verification into a single framework:
Intent Layer: Captures structured transaction instructions from users, agents, or applications.
Execution Layer: Managed by an "execution coordinator" responsible for executing instructions, sponsoring Gas fees, and applying governance logic.
Verification Layer: Records all results, strategies, and audit data on-chain.
Currently, Q402 is operational on the BNB Chain. BNB Chain is the first network to fully activate our execution architecture, perfectly demonstrating the "no Gas, strategy-aware" execution capability in a high-throughput production environment. Q402 is designed for multi-chain use, with BNB Chain serving as our starting point and model for expansion to other EVM networks. By integrating Q402, developers can easily achieve single-signature payments, automatic settlements, and agent interactions, all compliant with unified verifiable standards.
7. ChainCatcher: What technology ensures secure and Gas-free execution?
Rix: The core technology is based on two Ethereum standards: EIP-7702 and EIP-712.
EIP-7702 allows users to securely authorize an "execution coordinator" to pay Gas and execute complex transactions with a single signature at the protocol level.
EIP-712 ensures that users sign clearly defined intents and strategy rules, rather than vague requests.
The combination of these two standards enables execution that requires no trust and can perceive strategies.
8. ChainCatcher: What are the practical benefits for developers?
Rix: Our deployment on the BNB Chain has already validated several advantages:
Lower development costs: Our SDK can handle everything, eliminating the need to build the infrastructure for signing, Gas sponsorship, and execution from scratch.
General ERC-20 compatibility: Directly supports standard ERC-20 tokens without requiring token upgrades or new authorization processes.
Default no Gas fees: Transactions are executed through delegated sponsorship, so users don’t have to worry about it.
Production-grade reliability: Actual operation on the BNB Chain has resulted in a very low transaction failure rate.
Faster governance settlements: The "signature equals payment" process reduces governance settlement delays by over 70%.
Designed for agents: The architecture is specifically designed for automated, strategy-aware execution, making it particularly suitable for agents and high-frequency systems.
9. ChainCatcher: How is security and compliance ensured?
Rix: Each transaction can be linked to a verified identity through the "governance passport," while cryptographic techniques protect privacy. The operation of the "execution coordinator" is completely transparent, and we also provide optional compliance modules that support KYC, jurisdiction filtering, and strategy-based restrictions. Therefore, Q402 can seamlessly integrate into permissionless open ecosystems while also thriving in regulated financial environments.
How does the Quack AI ecosystem accelerate Q402?
10. ChainCatcher: What is the current adoption status of the Quack AI ecosystem?
Rix: We have laid a solid foundation, issuing over 7 million governance identities; integrating over 40 networks, verifying more than $3.5 million in on-chain revenue, and recording thousands of AI-driven governance actions. Q402 stands on this foundation, extending capabilities to all EVM-compatible networks.
11. ChainCatcher: Where did you primarily allocate the latest funding of $3.6 million from last year?
Rix: This $3.6 million was primarily invested in several areas: multi-chain expansion of the "execution coordinator"; SDK and API development for wallets and dApps; AI-driven strategy interpretation features; and pilot projects for RWA governance.
12. ChainCatcher: What role does the $Q token play in the system?
Rix: The $Q token is the connection point for participation, staking, and governance execution. Users can stake it to verified agents to earn execution fees and influence network strategies. The reward mechanism is based on constructive, transparent on-chain activities rather than speculation.
13. ChainCatcher: Can you share the upcoming development roadmap?
Rix: We plan to take several steps:
Promote the "signature equals payment" standard: solidify Q402's position as the default execution layer on BNB Chain and expand to more EVM networks.
Enhance agent capabilities: introduce reasoning proofs, protected execution, and inter-agent coordination mechanisms to make autonomous actions both explainable and executable.
Implement "pre-execution simulation": launch simulation and sandbox environments to allow project teams to thoroughly test governance, funding, and market strategies before going live with real assets.
Advance intelligent fund management: launch autonomous, strategy-aware fund management agents that can monitor, analyze, and coordinate execution in real-time.
Unify the agent economy: release Q402 mainnet v2, achieving adaptive strategy learning, cross-agent coordination, and establishing a shared execution registry across multiple protocols and chains.
14. ChainCatcher: Finally, please share your long-term vision.
Rix: Our long-term vision is to make Q402 the default execution layer for on-chain systems. We are moving towards a future where, regardless of the underlying chain, the assets used, or the applications involved, transactions, payments, and automated operations can all be authorized through a single intelligent, strategy-constrained signature.
Q402 will continue to evolve, going beyond basic execution to focus more on:
Smarter, more strategy-aware "signature equals payment" processes;
Agent-driven execution that can dynamically adjust based on real-time conditions;
Achieving verifiable, auditable actions at the system scale.
As agents, applications, and institutions fully transition to the blockchain, Q402 aspires to become the invisible underlying execution facility that securely, automatically, and cross-network translates intent into action.
