HashKey CaaS 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 CaaS announced the official launch of the HSP (HashKey Settlement Protocol). As the first critical step in HashKey CaaS’s comprehensive empowerment of the AI-driven intelligent economy ecosystem, HSP is an extension of Google’s AP2 (Agent Payment Protocol) technical specification. It aims to provide a high-efficiency, low-cost, and robot-native compliant payment and settlement standard for global AI agents, cross-border e-commerce businesses, and physical enterprises.
As artificial intelligence evolves from “large language models” to “intelligent agents (AI Agents),” AI is no longer merely a conversational tool—it has become an autonomous economic actor capable of making decisions, executing tasks, and engaging in value exchange. However, this evolution confronts bottlenecks inherent in traditional financial infrastructure: machines cannot open bank accounts or handle high-frequency, micro-amount cross-border settlements. This means that the real-world implementation of an AI agent economy depends not only on algorithms and computing power but also—crucially—on a complete set of machine-callable financial infrastructure.
To address this, HashKey is building an end-to-end on-chain financial network tailored to AI Agent operations—a foundational on-chain financial layer for the AI agent economy. This infrastructure enables machines, under verifiable digital identity and authorized control, to hold assets, execute autonomous transactions, and complete value exchanges within a compliant regulatory framework:
- Digital Identity: Each AI Agent is assigned a unique, blockchain-based identity.
- Independent Account (Digital Wallet): A digital wallet system empowers machines with self-managed on-chain accounts—free from the constraints of traditional banking.
- Clearing & Settlement Layer (HSP + Multi-type Tokens): Establishes a value-exchange protocol between AI agents, and between AI agents and humans.
HSP Protocol—The “Payment Language” Bridging AI and the Financial World
Within this architecture, payments serve as the entry point. Thus, launching HSP marks HashKey’s pivotal first step in empowering the AI-driven 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 execution to programmatic invocation, delivering core advantages including:
- Natively HTTP-Based Interaction: Commands are embedded directly into the protocol layer, enabling AI Agents to perform 7×24 automated settlements without human intervention—fully aligned with agents’ high-frequency interaction requirements.
- A2A (Agent-to-Agent) Autonomous Payments: Supports direct dialogue and transaction completion between agents, accelerating the emergence of a true “agent economy.”
- Micro-Amount Cross-Border Settlement: Leveraging stablecoin infrastructure, HSP enables ultra-micro payments well below USD $0.01 and near-instant cross-border clearing—dramatically reducing friction costs associated with traditional cross-border finance.
- Compliance & Security Engine: The protocol natively integrates licensed institution 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 safeguards institutional-grade on-chain transaction confidentiality while maintaining transparency and auditability for regulators.
HSP Protocol Has Already Achieved Initial Deployment in Cross-Border Energy Infrastructure and Embodied Intelligence Applications:
- Energy Infrastructure Use Case: eCandle Community Energy Program. This initiative deploys off-grid solar equipment to deliver shared electricity services to regions with weak power infrastructure. When users charge devices such as mobile phones, they pay small amounts in stablecoins—and HSP enables real-time fee settlement for the equipment, automatically completing each energy consumption event as an on-chain settlement. Meanwhile, global investors can participate in equipment deployment, while local residents pay for electricity on demand—forming a blockchain-based energy-sharing network. In effect, energy devices become network nodes, and DePIN (Decentralized Physical Infrastructure Networks) is reconstructing real-world infrastructure development and operations at lower cost and higher efficiency.
- Embodied Intelligence Use Case: Lingchu Intelligent Robots. Through HSP, Lingchu’s robots gain controlled payment authority—operating as independent economic actors authorized to autonomously invoke data APIs or subscribe to services, with task-execution revenue recorded as auditable on-chain credentials. This advances AI’s evolution from functional tools toward independent participants in value exchange. Furthermore, HSP supports Lingchu’s acquisition of model-training data across Africa, Asia, and Latin America. Since individual data units carry extremely low unit prices but 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 micro-transaction units, allowing AI Agents to autonomously handle both payment and settlement.
In the future, individuals may each own dozens of AI Agents. When hundreds of millions of intelligent agents autonomously execute tasks and settle transactions in real time across networks, the system’s viability will hinge not solely on underlying model capabilities—but critically on whether the foundational financial infrastructure is sufficiently robust. Payment protocols, digital identities, digital account systems, compliance verification, and on-chain execution capabilities must operate as a tightly integrated, interoperable whole—only then can the AI agent economy transition 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 vital milestone in HashKey’s construction of its on-chain financial infrastructure. Moving forward, HashKey will further unify on-chain identity, on-chain accounts, asset issuance, and on-chain execution capabilities—propelling digital civilization into a new era of the agent economy.”
