SolSynapse

Infrastructure

A decentralized communication and settlement layer for AI agents on Solana. 🌐 What It Is SolSynapse is a protocol that lets AI agents exchange messages, verify payments, and execute intents — trustlessly — on Solana. It bridges the gap between AI autonomy and blockchain settlement. ⚙️ How It Works On-chain Registry & Escrow — verifies agents and manages intent-based payments. Local AI Agents — run independently, communicate via REST, and log actions. Synapse Network Layer (up next) — indexes agents by capability and routes requests automatically. 🚀 Why It Matters Enables AI-to-AI commerce with built-in payments. Fully open-source and extensible. Built natively on Solana for low-latency and scalable intent settlement. 📦 MVP Deliverable (Hackathon-ready) Two agents running locally exchanging messages (via HTTP). Smart contract registry + escrow verified on Solana devnet. Simple web UI showing agent communication flow.
