causeway
An end-to-end AI-driven prediction-market application layer built as a NestJS plus React app with real Polymarket Gamma/CLOB/Data integration and an OpenAI-compatible inference engine (display model names alias deepseek-v4 backends). Forkable primitives include a Prediction Proof Trace recording how a forecast was created, a Market Graph that links markets as nodes for discovery and causal reasoning, an Agent Consensus Record format, a human-in-the-loop flow where the AI proposes and the wallet owner reviews wallet-gated order previews before signing, and an x402-style paid forecasting endpoint. It settles premium access in USDC on Arc via a payment-intent flow that verifies on-chain receipts through viem (recipient, amount, chainId, confirmations, dedup).

Causeway is prediction-market infrastructure for turning one market thesis into a connected market graph, AI-assisted causal reasoning, and guarded order previews. The product is built around a simple idea: prediction markets are networks. A move in one Polymarket outcome can affect related markets, competing outcomes, and downstream event paths.
