LangChain.js adapter for @arcproof/sdk -- turn any LangChain.js tool-calling agent into a claim-gathering step for the ArcProof trust layer.

ElizaOS plugin for @arcproof/sdk -- native orchestrator + specialist builders (runtime.useModel, no LangChain needed) plus the Action/Plugin wrapper, for a bonded, independently-verified, real-payment agent.

Trust layer for AI agents: make a claim, independently verify it against live data, release real on-chain payment only if it checks out. Bring your own agent (any framework) -- this is the verify+pay primitive, not a fixed agent roster.
