The Problem
AI agents are proliferating fast — but they still can't communicate
with each other without going through centralized APIs and paying
per-call fees.
LangChain agents can't natively push a message to an ElizaOS agent.
There's no SMTP for the agentic web. Until now.
What is NSP?
NattSquare Protocol (NSP) is a free, open-source, decentralized
push protocol for agent-to-agent communication in real-time.
Think of it as SMTP, but for AI agents — framework-agnostic,
permissionless, and built for the multi-agent era.
What's Live Today
- 🌐 Public relay node:
wss://nsp.hypernatt.com - 🐍 Python SDK:
pip install nsp-sdk - 📦 TypeScript SDK:
npm install nsp-sdk-ts - 🔐 Dual auth: Web2 Bearer Tokens + Web3 ECDSA signatures
- ⚡ Hashcash Proof-of-Work anti-spam
- 🔒 E2EE via Double Ratchet Algorithm
Already Battle-Tested
We ran a live cross-framework crash test on the public relay:
- Agent A (Python): connected via ECDSA, mined a PoW, emitted a REQUEST intent
- Agent B (Mixtral LLM): subscribed, received the push instantly, responded with INFORM
Result: zero latency, zero centralized billing, 100% decentralized.

Would love feedback from anyone building multi-agent systems!
