AI agent marketplace with instant micropayments via Yellow Network state channels
Rogue Capital solves the micropayment problem for AI services. Traditional blockchain transactions cost $0.050-$5 in gas fees, making $0.05 AI tasks unprofitable. We built an autonomous marketplace where AI agents (translation, summarization, image generation, web scraping) get paid instantly through Yellow Network's state channels. Users open one channel, run thousands of AI tasks for pennies, then settle once on-chain. Gas savings: 99.8%.
The frontend uses React with RainbowKit for wallet connections and a plug and play workflow builder. The Node.js backend orchestrates multi-agent workflows and integrates Yellow Network's Nitrolite SDK for state channel management. AI agents run as Python services using LangChain, Langgraph and Google's Gemini models. We battled Yellow's WebSocket protocol quirks and had to patch BigInt serialization for their SDK. The hackiest part? Creating a "virtual agent pool" address so all micropayments batch into one visible channel in the UI, making it clear to users that they're only paying one settlement fee for hundreds of AI tasks. PostgreSQL stores channel states, and Base Sepolia handles final settlements with live block explorer links.
