Aser

Aser is an open source Python framework for building AI agents with native Web3 capabilities, developed by Ame Network. It lets developers assemble an agent in a few lines of code by combining a language model with modular components for knowledge retrieval, memory, tracing, reasoning, tools and social clients, and then connecting that agent to blockchain applications. It is intended for developers building agents for onchain ecosystems. Aser works with models from OpenAI, Anthropic, Grok, Gemini and DeepSeek, and integrates services such as Chroma, Exa, Deepgram and Supabase. Documented examples cover retrieval augmented knowledge, memory storage, built in toolkits, API servers, a command line interface, and clients for Discord, Telegram and Farcaster. More advanced patterns include chain of thought, Model Context Protocol tools, text to SQL, custom workflows, agent evaluation and router, sequential, parallel, reactive and hierarchical multi agent setups. It also supports the Google Agent2Agent protocol and Ame's Model Smart Contract Protocol, which lets language model applications interact with EVM compatible networks. Aser is free to install from PyPI or clone from GitHub. No paid plan is published; the Ame Network pricing page could not be read, and the framework itself carries no licence fee, though model and service providers bill separately. Aser sits within a wider Ame Network stack that includes an onchain component system, a JavaScript SDK, a component explorer called Ame Scan, a React UI library for agent interfaces, and two Ethereum improvement proposals authored by the team.
