What is base-agent?

BunnyOS is an open-source AI agent for the Base blockchain ecosystem. Base is a blockchain network built by Coinbase. The project describes itself as the first open-source agent built on top of Base MCP, which is a protocol that gives AI agents access to wallet and transaction tools on Base. The idea is that instead of using a proprietary service to interact with crypto on Base, users can run their own copy of the agent, inspect the code, and keep their private keys in their own hands. The agent has four main systems. The first handles chat and autonomous background scanners: users can have a conversation with the agent about their wallet and DeFi positions, and separately configure scheduled scanners that run automatically on intervals from one minute to twenty-four hours. Scanners generate either alerts (informational notices like a yield dropping) or recommendations (suggested actions with a button to execute them). The second system is a tab-based terminal interface where each tab has its own isolated context. The third is a memory system based on a markdown file that holds the user's preferences, risk tolerance, and other context, which is fed to the agent before each interaction. The fourth is a tool system built on MCP that connects to data providers including Moralis for on-chain history, CoinMarketCap for price data, DeFi Llama for protocol yield data, and Morpho for lending market data. The security model is explicit about one point: the agent never holds private keys. Any transaction it proposes requires the user to approve it separately in the Base mobile app. API keys stored in the database are encrypted at rest using AES-256-GCM. Self-hosting requires Node.js 24, pnpm, and PostgreSQL 18. Two processes run separately: an API server and a frontend interface. Configuration is done through an environment file with three required variables. The README was written by the two founders and explains at length why they chose open source: they argue that autonomous agents handling real money cannot be trusted if the code is closed and the operator has financial incentives tied to transaction volume.
