With the rapid growth of Multi-Agent Systems and AI applications, "agent autonomous payment and settlement" is quickly transitioning from concept to reality. To truly scale this vision, developers need not only a high-performance payment network but also equally robust security infrastructure.
In this context, BitsLab officially announces its collaboration with Questflow:
BitsLab joins the Questflow ecosystem to build the underlying infrastructure for the multi-agent economy in collaboration with multiple partners; BitsLab provides secure APIs and a secure Agent (BitsLab Safe) for the x402 ecosystem, offering protection for on-chain payments and AI-Agent interactions.
Below, we will explain the model and practical value of this collaboration from two dimensions.
1. x402 + Questflow + BitsLab: A New Tech Stack for the Multi-Agent Economy
Since the launch of x402 by Coinbase, payments are being redefined:
Native Internet payment protocol: Based on HTTP/402, making "payment" as simple as returning a status code;
Designed for AI and APIs: Pay-per-use, low cost, and instant settlement—naturally suitable for model inference, API gateways, and automated processes;
Payments occur directly on-chain: Using stablecoins like USDC for settlement, eliminating intermediaries and cumbersome reconciliation processes.
At the same time, Questflow is building the "operating system" for the multi-agent economy: coordinating different AI Agents to work together through the Multi-Agent Orchestration Protocol (MAOP); covering decision-making, communication, action, and on-chain layers, enabling Agents to safely execute complex on-chain tasks; providing developers with a unified interface that integrates governance, execution, and payment into a complete workflow.
On top of this tech stack, BitsLab provides the security layer:
Through secure APIs and the BitsLab Safe Agent, it offers risk control and compliance capabilities for x402 payment paths and Questflow multi-agent tasks; BitsLab transforms its accumulated security rules from multiple blockchains, audits, and attack intelligence into callable security services.
A simple analogy can illustrate the relationship among the three:
x402 is responsible for "receiving and making payments";
Questflow is responsible for "orchestrating agents";
BitsLab ensures that "money can move safely."
2. Significance for Developers and the Ecosystem: Making Security a Default Capability
This collaboration brings at least three layers of value to developers and the multi-agent/payment ecosystem.
1. Security by Default
Developers using Questflow and x402 no longer need to build a complete security system from scratch; they can directly obtain:
Whitelist and blacklist capabilities
Rule engines and data validation mechanisms
Basic risk assessment and alert capabilities
Security thus becomes a built-in capability of the infrastructure—no additional development work is required.
2. Agents Can "Spend Money with Confidence"
When AI Agents use x402 to call third-party APIs, purchase computing power, or data services,
the BitsLab Security Agent can intervene in critical paths to:
Identify abnormal requests or responses;
Flag potential risk endpoints or counterparties;
Provide decision signals to the upper orchestration system: allow/deny/require manual review.
This means that Agents are not only able to make autonomous decisions and actions,
but will conduct "spending" operations within controlled, transparent, and secure boundaries.
3. Establishing Trust and Compliance Foundations at the Ecosystem Level
As the scale of multi-agent systems and on-chain payments continues to grow,
the demand for compliance and risk management will also rapidly increase.
Leveraging BitsLab's accumulated security data and experience in a multi-chain environment,
the x402 + Questflow ecosystem can more proactively:
Build security and compliance models suitable for enterprise and institutional users;
Maintain observability, measurability, and governability of risks—even during high-growth phases.
Building Scalable, Payable, and Secure Multi-Agent Infrastructure
The potential of the multi-agent economy is immense, but to transition from Demo to a true "multi-agent GDP,"
three layers of infrastructure need to mature in sync:
Payment layer → x402 transforms payments into a capability that can be completed with "one line of code";
Orchestration layer → Questflow enables Agents to work collaboratively, forming complete workflows;
Security layer → BitsLab is committed to being a long-term, stable security cornerstone of this system.
In the coming month, BitsLab and Questflow will advance the planned integration milestones. We also welcome developers who are already using x402 or Questflow to communicate their security needs with us— let's work together to build a safer and more user-friendly multi-agent ecosystem.
About BitsLab
BitsLab is an AI security company focused on digital asset security, dedicated to providing integrated solutions of "audit services + AI security engine + security tools" for the emerging Web3 ecosystem, helping project teams and end users build, trade, and use digital assets more securely on-chain.
In the overall security solution, BitsLab comprises a complete AI security system with BitsLab AI Scanner + BitsLab Safe: BitsLab Safe, as an AI-based Web3 security product, provides enterprise-level protection, simulating transactions in real-time, identifying scams and malicious contracts, and relying on BitsLab's agentic security stack to protect x402 payments and various AI Agent's on-chain operations; BitsLab AI Scanner executes intelligent audits and risk detection based on vulnerability and threat data engines, significantly improving efficiency and reducing false positives.
BitsLab has three sub-brands: MoveBit, ScaleBit, and TonBit, continuing to deepen its expertise in emerging ecosystems such as Sui, Aptos, TON, Solana, Linea, BNB Chain, Soneium, and Starknet, providing professional auditing and vulnerability discovery services to help projects maintain the security and controllability of core infrastructure during rapid iterations. The BitsLab team consists of several top vulnerability research experts, who have won multiple international CTF awards and have discovered and disclosed critical vulnerabilities in well-known projects such as TON, Aptos, Sui, Nervos, OKX, and Cosmos, promoting ecosystem security upgrades.
