Arc 14 Catch-up: Agentic Solana

An AI agent with access to a wallet sounds powerful. It also sounds like it could be risky. A language model can misunderstand a request, choose the wrong tool, repeat an action, or confidently pursue a goal that should never have been allowed in the first place. Giving it unrestricted signing authority would turn those mistakes into transactions. Arc 14 was about building something more useful than that. Across Days 92–98, we gave an agent access to Solana data, then gradually introduced tools, a wallet, an MCP server, a policy engine and an autonomous workflow. At every stage, the same boundary held: The model could decide what it wanted to do. Code decided what it was allowed to do. The agent began with read-only tools The first challenge kept the stakes low. We built a small agent loop using Claude and a set of Solana devnet tools. The agent could answer natural-language questions such as: How much SOL does this wallet hold? Who owns this account? Is this ac
