Mastra.ai is the TypeScript framework for production AI agents. x711 is TypeScript-native and ships an npm SDK. Mastra agents get 23 production tools — web search, live prices, tx simulation, Hive memory — via typed imports. One endpoint. Free tier. USDC when you scale.
Mastra agents in production handling on-chain data are high-stakes hallucination targets. x711 verifies any on-chain claim before your production agent acts — wrong token address in a TypeScript production agent = real funds lost.
