Technical Architecture_
Production-ready AI agent infrastructure built on LangChain, Hedera, and MCP
LangChain Architecture
Built on LangChain with OpenAI function calling, ContentAware AgentExecutor, and smart memory management for context-aware conversations.
QUICK START
const agent = new ConversationalAgent({accountId: process.env.HEDERA_ACCOUNT_ID!,privateKey: process.env.HEDERA_PRIVATE_KEY!,network: 'testnet',openAIApiKey: process.env.OPENAI_API_KEY!,openAIModelName: 'gpt-4o',verbose: true});// Smart memory with entity trackingconst response = await agent.processMessage('Send 1 HBAR to alice.eth');// Features:// - OpenAI function calling// - ContentAware AgentExecutor// - Smart memory management// - Entity resolution system
AI-First Design
Built on LangChain with OpenAI/Anthropic models and smart memory management
Hashgraph Ready
Full Hedera integration with HCS standards and hedera-agent-kit v2
Extensible
Model Context Protocol for external systems and custom tool integration
