Zen7 Payment Agent - An open-source decentralized payment agent from Zen7 Labs

What is Zen7 Payment Agent?

Zen7 Payment Agent, launched by Zen7 Labs, is the world's first decentralized payment agent (DePA). Based on a multi-agent collaborative architecture, it supports multi-chain, multi-currency, high-frequency, small-amount payments, using password-free authorization and gas payment mechanisms to improve payment efficiency and security. Zen7 Payment Agent enables automated payments between AI agents, supports A2A and MCP protocols, and is compatible with mainstream stablecoins and wallets. As a next-generation smart payment infrastructure, Zen7 Payment Agent provides an efficient and secure payment solution for the AI agent economy, promoting more convenient and intelligent business interactions between agents.

Main functions of Zen7 Payment Agent

• AI-powered autonomous paymentZen7 Payment Agent enables AI agents to initiate payments autonomously, just like humans, without human intervention. It supports high-frequency, small-amount payment scenarios and meets the needs of AI-to-AI collaboration.
• Multi-chain compatibility and cross-chain paymentsIt supports multi-chain deployment across the entire EVM ecosystem, is compatible with mainstream stablecoins and asset types, enables seamless cross-chain payments, and breaks down barriers between chains.
• Password-free authorization and smooth experienceUsing the "one-time authorization, multiple password-free" mechanism, the AI intelligent agent can automatically initiate payments within the authorized limit, providing a user experience close to Web2.
• Zero-management and security guaranteeBased on the EIP-712 signature standard, it enables on-chain verifiable amount and time control, eliminating the need for custodian assets and fundamentally ensuring fund security.
• Gas payment mechanismSettlement Agent handles gas fees, eliminating the technical barriers to crypto payments and making transactions smoother and more seamless.
• High-frequency small-amount payment adaptationIt natively supports AI-to-AI collaboration (A2A) and multi-agent collaboration protocol (MCP), perfectly meeting the needs of high-frequency, small-amount payment scenarios and applicable to various micro-payment needs in the AI economy.
• Open Collaborative EcosystemIt features an open-source core Agent module, MCP service, and command-line tools, encouraging global developers to collaborate on building a next-generation payment network.

The technical principles of Zen7 Payment Agent

• .Multi-Agent Collaborative ArchitectureZen7 Payment Agent employs a multi-agent collaborative architecture, automating the payment process through the division of labor and collaboration among different roles. The Host Agent, as the core coordinator, is responsible for understanding payment intentions, managing payment status, and coordinating the work of other agents; the Payer Agent is responsible for creating payment orders, generating EIP-712 signatures, and verifying wallet balances; the Settlement Agent is responsible for executing on-chain transactions, monitoring transaction status, and completing settlement; and the Payee Agent is responsible for receiving settlement notifications, confirming order creation, and notifying payment completion, ensuring the efficiency and security of the payment process.
• Password-free authorization mechanismThis is a passwordless authorization mechanism based on the EIP-712 signature standard. When authorizing, the user signs a signature containing a limit and time range; the smart agent does not need to repeat the signature when operating within the authorized limit. This mechanism not only simplifies the payment process and reduces the number of interactions between the user and the smart contract, but also reduces security risks and ensures the safety of user funds.
• Gas payment mechanismTo lower the technical barrier to crypto payments, the Zen7 Payment Agent introduces a Gas payment mechanism. The Settlement Agent handles the payment of gas fees for on-chain transactions, eliminating the need for users to directly manage gas costs. This makes the payment process smoother and more seamless, alleviating user concerns about gas fee fluctuations and improving the user experience.
• Protocol Adapter LayerProvides a protocol adaptation layer that supports multiple protocols. a2a_server implements Google's Agent-to-Agent protocol and supports collaborative communication between agents through the A2AStarletteApplication framework; mcp_server implements the Model Context Protocol (MCP), encapsulating payment functionality into a tool API and supporting SSE (Server-Sent Events) transmission.

Application Scenarios of Zen7 Payment Agent

• Content creation and copyright paymentThe intelligent content creation system can automatically purchase image materials and pay copyright fees without human intervention, thus improving creation efficiency.
• Data Analysis and Data Source SubscriptionThe data analysis intelligent agent can directly subscribe to data sources and complete the settlement, quickly obtain the required data, and assist in data analysis work.
• AI Collaboration and Revenue SharingAI-to-AI (A2A) collaboration enables automatic revenue sharing after projects are completed, simplifying the collaboration process and improving efficiency.
• Cross-border AI application paymentCross-border AI applications can complete payments instantly, eliminating the need to wait for cumbersome settlement processes and improving the payment efficiency of cross-border businesses.
• e-commerce scenariosIn e-commerce scenarios, shopping agents can automate the entire process of product browsing, ordering, and payment, thereby improving the user experience.
