LangGraph-Chatchat functions as a memory management plugin for the ChatChat conversational framework, utilizing LangGraph’s graph database model to store and retrieve conversation context. During runtime, user inputs and agent responses are converted into semantic nodes with relationships, forming a comprehensive knowledge graph. This structure allows efficient querying of past interactions based on similarity metrics, keywords, or custom filters. The plugin supports configuration of memory persistence, node merging, and TTL policies, ensuring relevant context retention without bloat. With built-in serializers and adapters, LangGraph-Chatchat seamlessly integrates into ChatChat deployments, providing developers a robust solution for building AI agents capable of maintaining long-term memory, improving response relevance, and handling complex dialog flows.

Solana AI Agent Eliza is a proof-of-concept AI agent that brings the classic Eliza chatbot onto the Solana blockchain. It comprises an Anchor-based Rust smart contract that implements the Eliza dialogue patterns and a lightweight web frontend. When a user submits a message, the frontend invokes the on-chain program, which generates an Eliza-style response and writes both the prompt and reply into a Solana account. This design demonstrates how to integrate simple AI logic directly on-chain, ensuring immutable, auditable conversation logs, and provides a template for developers to build more advanced AI agents on Solana.
