Ecosystem

Most Layer 2s are built for transactions. House Party Protocol is built for agents.

HPP is an AI-native L2 where autonomous agents execute, reason, and pay onchain — and where developers have the tools to build them. Each product below is one layer of that stack.

OpenHPP · The agent runtime​

Closed beta — public access coming soon

A secure operating space for AI agents in the HPP family. Autonomous agents run in fully isolated Linux containers, with session-key access control, one-click deployment, and real-time execution visibility.

  • Fully isolated Linux containers
  • Dynamic session-key access control
  • One-click managed deployment

HPP Router · The model router​

Live

An LLM inference router for the HPP ecosystem, sending each request to the right model across the network — including HPP Coder. A Router portal with an OpenRouter-style UI for model discovery, API keys, and testing is on the way.

HPP Coder · The coding LLM​

Live

A coding LLM purpose-built for Smart Contract developers in the HPP ecosystem. Served through HPP Router and offered free via HPP Hub.

→ HPP Coder docs

HPP Hub · The developer portal​

Live

Your access point to House Party Protocol's developer tools — and where HPP Coder is offered free.

x402 · The payment layer​

Onchain payments

The open payment standard (HTTP 402) that lets AI agents pay onchain with a single signature — no accounts, no checkout. HPP is registered in the x402 asset registry as a default-asset chain (190415) with USDC settlement, so every agent and app in the ecosystem can transact natively.
