For this vision to scale, developers need not only a high-performance payment network, but also a security infrastructure of equal strength.
Against this backdrop, BitsLab is officially partnering with Questflow:
- •BitsLab joins the Questflow ecosystem, working with multiple partners to build the foundation of the multi-agent economy;
- •BitsLab provides the x402 ecosystem with Security APIs and a Security Agent (BitsLab Safe), delivering protection for on-chain payments and AI-Agent interactions.
Below, we explain the collaboration model and its practical value through two dimensions.
x402 + Questflow + BitsLab: A New Stack for the Multi-Agent Economy
Beginning with Coinbase’s launch of x402, payments are being redefined:
- •Internet-native payment protocol: Built on HTTP/402, making “payments” as simple as returning a status code;
- •Born for AI and APIs: Pay-per-call, low-cost, second-level settlements—naturally suited for model inference, API gateways, and automated workflows;
- •Payments happen directly on-chain: Settled in stablecoins like USDC, eliminating intermediaries and lengthy reconciliation processes.
Meanwhile, Questflow is building the “operating system” of the multi-agent economy:
- •Through Multi-Agent Orchestration Protocol (MAOP), it coordinates different AI Agents to work together;
- •It covers the decision layer, communication layer, action layer, and on-chain layer, enabling agents to safely perform complex tasks on-chain;
- •It provides developers with unified interfaces, linking governance, execution, and payment in a single workflow.
On top of this stack, BitsLab provides the security layer:
- •Through Security APIs and the BitsLab Safe Agent, BitsLab brings risk control and compliance capabilities to x402 payment pathways and Questflow’s multi-agent tasks;
- •BitsLab converts its accumulated security rules—across multiple blockchains, audits, and attack intelligence—into callable security services.
A simple analogy:
- •x402 handles “sending and receiving money,”
- •Questflow handles “orchestrating the agents,”
- •BitsLab ensures “the money moves safely.”
What This Means for Developers and the Ecosystem: Making Security a Default Capability
This partnership brings at least three layers of value to developers and the broader multi-agent / payment ecosystem.
1. Security by Default
Developers using Questflow and x402 no longer need to build a full security stack from scratch; they instantly gain:
- •Blacklist / whitelist capabilities
- •Rule engines and data-validation mechanisms
- •Basic risk assessment and alerting abilities
Security becomes a default capability, delivered with the infrastructure itself—no extra work required.
2. Agents Can “Spend Money with Confidence”
When AI Agents use x402 to call third-party APIs, purchase compute, or buy data services,
the BitsLab Security Agent can intervene in critical paths to:
- •Identify abnormal requests or abnormal responses;
- •Flag potentially risky endpoints or counter-parties;
- •Provide decision signals—allow / deny / manual review—to upper-layer orchestration.
This means agents won’t just decide and act autonomously;
they will operate within controlled, transparent, and safe boundaries when spending money.
3. Establishing Trust and Compliance at the Ecosystem Level
As multi-agent systems and on-chain payments scale, the needs for compliance and risk management will grow rapidly.
Leveraging BitsLab’s experience across multiple chains and its extensive security datasets,
the x402 + Questflow ecosystem can more proactively:
- •Build security and compliance models acceptable to enterprise and institutional users;
- •Maintain observability, measurability, and governability of risks—even during aggressive growth.
Building Multi-Agent Infrastructure That Is Scalable, Payable, and Secure
The multi-agent economy holds massive potential, but moving from demos to real “multi-agent GDP” requires the simultaneous maturity of:
- •The payment layer → x402 turns payment into a “one-line-of-code” capability;
- •The orchestration layer → Questflow enables agents to work together and form complete workflows;
- •The security layer → BitsLab aims to be the long-term, stable security foundation of this system.
In the coming month, BitsLab and Questflow will continue moving forward with planned integration milestones.
Developers currently utilizing x402 or Questflow are encouraged to engage with the team to discuss security requirements, contributing to the development of a more secure and user-friendly ecosystem.
About BitsLab
BitsLab is an AI-driven security company focused on digital asset protection. It delivers an integrated solution of “audit services + AI security engine + security tools” for emerging Web3 ecosystems, helping developers and end users build, trade, and interact on-chain with greater safety.
Within its security framework, BitsLab combines BitsLab AI Scanner and BitsLab Safe to form a complete AI-powered protection system. BitsLab Safe, an AI-based Web3 security product, provides enterprise-grade defense by simulating transactions in real time, detecting scams and malicious contracts, and securing x402 payments and AI Agent operations through BitsLab’s agentic security stack. BitsLab AI Scanner, built on a vulnerability and threat intelligence engine, performs intelligent auditing and risk detection to improve efficiency and reduce false positives.
BitsLab operates three sub-brands—MoveBit, ScaleBit, and TonBit—serving ecosystems such as Sui, Aptos, TON, Solana, Linea, BNB Chain, Soneium, and Starknet. The team offers professional audits and vulnerability research to keep core infrastructure secure during rapid iteration. Its researchers have won multiple international CTF awards and discovered critical vulnerabilities in TON, Aptos, Sui, Nervos, OKX, Cosmos, and other major ecosystems, driving meaningful improvements in industry-wide security.
