HashKey Chain Fully Empowers the AI Agent Economy and Launches the HSP AI Settlement Protocol
The launch of HSP is HashKey’s critical first step in empowering the AI-powered intelligent economy.
Navigating Web3 tides with focused insightsHashKey Chain announced the official launch of the HSP (HashKey Settlement Protocol). As the first critical step in HashKey Chain’s comprehensive empowerment of the AI-powered intelligent economy ecosystem, HSP is an extension of the AP2 (Agent Payment Protocol) technical specification initiated by Google. It aims to deliver a high-efficiency, low-cost, and natively robot-friendly standard for compliant payments and settlements—serving global AI agents, cross-border e-commerce platforms, and physical enterprises alike.
As artificial intelligence evolves from “large language models” to “intelligent agents (AI Agents),” AI is no longer merely a conversational tool but rather an autonomous economic actor capable of making decisions, executing tasks, and engaging in value exchange. Yet this evolution confronts bottlenecks inherent in traditional financial infrastructure: machines cannot open bank accounts or efficiently handle high-frequency, micro-value cross-border clearing. Thus, the real-world implementation of an AI agent economy depends not only on algorithms and computing power—but crucially on a full suite of machine-callable financial infrastructure.
To address this, HashKey is building an end-to-end on-chain financial network tailored specifically for AI Agent operations—laying the foundational on-chain financial infrastructure for the AI agent economy. This infrastructure enables machines—under verifiable digital identity and proper authorization—to hold assets, execute autonomous transactions, and complete value exchanges within a compliant regulatory framework:
- Digital Identity: Assigns each AI Agent a unique, blockchain-based identity.
- Independent Account (Digital Wallet): Through a digital wallet system, machines gain independently managed on-chain accounts—free from the constraints of traditional banking.
- Clearing & Settlement Layer (HSP + Multiple Token Types): Establishes a value-exchange protocol between AI agents, and between AI agents and humans.
HSP Protocol—The “Payment Language” Bridging AI and Finance
In this architecture, payment serves as the entry point. Hence, launching HSP marks HashKey’s pivotal first step toward empowering the AI-powered intelligent economy. If stablecoins are the “money” of the AI era, then HSP is the “payment language” of the AI economy. Built upon Google’s AP2 technical specification, HSP upgrades payment capabilities from “manual operation” to “programmatic invocation,” delivering key advantages including:
- Natively HTTP-Based Interaction: Commands are embedded directly at the protocol layer, enabling AI Agents to perform 24/7 automated settlement without human intervention—fully aligned with AI agents’ high-frequency interaction requirements.
- A2A (Agent-to-Agent) Autonomous Payments: Supports direct dialogue and execution of orders and payments between agents—accelerating the emergence of a genuine “agent economy.”
- Micro-Value Cross-Border Settlement: Leveraging stablecoin infrastructure, HSP supports ultra-micro payments far below USD $0.01 and enables near-instant cross-border clearing—significantly reducing friction costs associated with traditional cross-border finance.
- Compliance & Security Engine: The protocol natively integrates licensed institutional verification nodes and on-chain AML (anti-money laundering) mechanisms—ensuring every machine-initiated transaction is auditable, verifiable, compliant, and secure. Privacy-preserving transaction functionality is also supported, safeguarding enterprise-grade on-chain transaction confidentiality while maintaining regulatory transparency and auditability.
HSP Protocol Has Already Achieved Initial Deployment in Cross-Border Energy Infrastructure and Embodied Intelligence:
- Energy Infrastructure Use Case: eCandle Community Energy Program. This initiative deploys off-grid solar equipment to provide shared electricity services to regions with underdeveloped power infrastructure. Users charging mobile devices, for example, can make micropayments using stablecoins—while HSP enables real-time fee settlement for the equipment, automatically completing on-chain settlement for every unit of electricity consumed. Simultaneously, global investors may participate in equipment deployment, while local residents pay for electricity on demand—creating a blockchain-based energy-sharing network. This means energy equipment becomes a network node, and DePIN (Decentralized Physical Infrastructure Networks) is reconstructing real-world infrastructure development and operations—more cost-effectively and efficiently than ever before.
- Embodied Intelligence Use Case: Lingchu Intelligent Robots. Through HSP, Lingchu’s intelligent robots have acquired controlled payment permissions—enabling them to autonomously invoke data APIs or subscribe to services as independent economic actors. Revenue generated from task execution is recorded as auditable on-chain credentials—advancing AI’s evolution from functional tools to independent participants in value exchange. Additionally, HSP supports Lingchu’s acquisition of model training data across Africa, Asia, and Latin America. Since individual data units carry extremely low value yet require extremely high transaction frequency, traditional financial systems struggle to support such micro, high-frequency payment scenarios. With HSP, data collection tasks can be decomposed into machine-executable microtransaction units—automatically paid for and settled by AI Agents.
In the future, individuals may each own dozens of AI Agents. When hundreds of millions of such agents autonomously execute tasks and settle payments in real time across networks, the viability of this entire system will hinge not solely on underlying model capabilities—but on whether the foundational financial infrastructure is sufficiently mature. Payment protocols, digital identities, digital account systems, compliance verification, and on-chain execution capabilities must function as a tightly integrated, interoperable whole—so that the AI agent economy can evolve from concept to large-scale application.
Li Chen, CEO of HashKey’s On-Chain Business Unit, stated: “Launching HSP is not merely the release of a single product—it represents a significant milestone in HashKey’s construction of its on-chain financial infrastructure. Going forward, HashKey will further integrate on-chain identity, on-chain accounts, asset issuance, and on-chain execution capabilities—propelling digital civilization into a new era of agent-driven economics.”
