VPAI

VPAI: The Framework for Building Personal AI Assistants VPAI (Virtual Personal Agentic Intelligence) is an innovative framework designed for building intelligent, personal AI assistants that act autonomously on behalf of users. Built on Coinbase’s Agent Kit, VPAI enables the creation of highly customisable, agentic AI systems that can execute tasks, make informed decisions, and seamlessly interact with Web3 and traditional digital environments.

Key Features Autonomous Task Execution – VPAI enables AI assistants to act independently based on user-defined parameters, reducing manual input while ensuring efficiency. Modular and Extensible – Developers can easily extend functionality by integrating additional modules for Web3 transactions, smart contract interactions, and on-chain identity management. Secure by Design – Built with best-in-class cryptographic standards and access control mechanisms to protect user data and transactions. Seamless Web3 Integration – Supports blockchain-native functionalities, such as account abstraction, self-custodial wallets, and token-gated access. Natural Language Processing (NLP) and Reasoning – Utilises advanced AI models to understand and execute complex user requests with human-like reasoning. Customisable Personalisation – Users can define preferences, routines, and decision-making rules to tailor their AI assistant’s behaviour to their needs. Use Cases Web3 AI Agents – Personal assistants that can manage crypto transactions, execute smart contract interactions, and automate DeFi strategies. Financial AI Advisors – Assistants that monitor portfolio performance, suggest optimal investment strategies, and alert users to key market movements. Automated Compliance & KYC Agents – AI systems that handle identity verification, transaction monitoring, and regulatory compliance for Web3 businesses. Gaming & Metaverse Companions – Intelligent NPCs and AI-driven player assistants that enhance gaming experiences by executing tasks and making strategic decisions. Enterprise Productivity – AI-driven task managers that automate workflows, schedule meetings, and interact with APIs for business automation.

VPAI operates as an autonomous, event-driven AI agent with an on-chain and off-chain hybrid architecture:

User Input & NLP Processing

The user inputs commands via the UI, voice, or a chat interface. The AI agent processes the command using LangChain or a fine-tuned local LLM. Decision-Making & Execution

The agent determines whether the action is Web2 (e.g., sending an email) or Web3 (e.g., executing a smart contract). It queries blockchain states (via Ethers.js/Viem) and off-chain APIs (via Node.js & FastAPI). If required, it requests user approval for transactions via Coinbase Wallet SDK or executes autonomously via Account Abstraction. On-Chain Transactions

If a transaction is required, the AI agent bundles the request, signs it with a smart contract wallet, and submits it to the chain. All transactions are either gasless (via sponsored transactions) or use a built-in staking mechanism for covering gas fees. Secure Data Storage & Messaging

Sensitive user data is encrypted using Lit Protocol and stored on IPFS. VPAI agents communicate securely via XMTP, enabling cross-platform interactions.
