Built for Tokyo Dome City

The Infrastructure Layer

for the Agentic Era

Open-Dome is the plug-and-play, enterprise-grade infrastructure suite that powers next-generation Agentic workflows. Secure bridges for AI agents, multi-chain Web3, and real-time communication — reduced to a single SDK.

The Problem

Building Agentic infrastructure is expensive, slow, and insecure

Agentic workflows — autonomous AI agents interacting with modular apps on behalf of users — are the future. But every development team wastes months reinventing the same critical infrastructure.

Insecure Agent-to-App Auth

How do you securely authorize an AI agent to act on behalf of a user in a third-party app without exposing credentials? Every team rebuilds this from scratch — badly.

Multi-Blockchain Chaos

Supporting any EVM (Base, Monad, Ethereum, Arbitrum), Solana, and Starknet means three different SDKs, three codebases, and three potential points of failure. The fragmentation is expensive.

Invasive Device Permissions

Autonomous agents that request GPS, camera, or sensor access trigger alarming system prompts. Users abandon workflows that feel invasive, even when the intent is harmless.

Architecture

One bridge between AI Agents and every App

Open-Dome sits between autonomous agents and third-party modules, handling the complex security handshakes, blockchain routing, and real-time messaging so developers can focus on building experiences.

Host App

The Agent / Host

Injects user data, GPS & wallet addresses

Open-Dome Infrastructure

Zero-Trust Security

Unified Web3 Access

Real-Time Events

Location Privacy

Plug & Play SDK

Mini-App

Third-Party Module

Token verification happens exclusively on the server. The raw token list is never exposed to the client. JWTs are generated fresh per session with HS512 signing and 1-day expiry.

SDK Features

Enterprise-grade abstractions for modular apps

Everything your Mini-App needs to securely communicate with the Host, access blockchain networks, stream real-time data, and respect user privacy — through a single SDK.

Zero-Trust Security

Server-verified handshakes, never client-side

The Host app verifies all users server-side before injecting credentials into the Mini-App container. Tokens are validated via the /api/verify endpoint against a server-side allowlist.

example.js

const { isAuthorized, token, context } = useOpenDome(); // context: username, theme, lang, wsJwt

Multi-Chain Web3

One API across any EVM, Solana & Starknet

A unified blockchain interface that seamlessly routes across any EVM (Base, Monad, Ethereum, Arbitrum, etc), Solana, and Starknet. Fetch balances, sign transactions — zero chain-specific code required.

example.js

const balances = await blockchain .getBalances({ base: '0xA1b2...', solana: '3Kz...', starknet: '0x04a...' });

Real-Time Events

MQTT-powered pub/sub messaging

A dedicated, secure channel for instant messaging between apps and the host. Low-latency MQTT broker with JWT-authenticated connections for real-time data syncing.

example.js

Events.connect({ jwt: context.wsJwt }); Events.subscribe( 'opendome/public/events', (data) => handleEvent(data) );

Location Privacy

GPS without invasive permissions

The Host safely proxies GPS data to the Mini-App. No direct device permissions needed — no scary iOS/Android prompts that cause users to abandon your app.

example.js

// Automatically uses proxied location // when available inside the Host const { proxiedLocation } = useOpenDome(); const { latitude, longitude } = proxiedLocation;

Ecosystem

Three pillars. One complete development experience.

Open-Dome isn't just an SDK — it's a complete ecosystem for building, testing, and shipping modular applications for Agentic environments.

The Engine

The SDK

Months of infrastructure engineering, reduced to a single line of code. Developers drop our lightweight SDK into their Mini-App. Behind the scenes, it handles security handshakes, blockchain connections, and live event streaming automatically.

open-dome-lib

The Proving Ground

The Sandbox

A professional-grade testing laboratory. Load your Mini-App into the Sandbox to simulate exactly how it performs when interacting with an AI agent — test security injections, user profiles, themes, and real-time GPS tracking safely before deploying to production.

The Blueprint

Example Mini-App

A production-ready reference implementation featuring a multi-chain crypto wallet, live map using proxied GPS, and an interactive game powered by real-time MQTT. Fork this blueprint and have a working app by the afternoon.

Developer Experience

Months of infrastructure. One hook.

The entire Open-Dome SDK is consumed through a single React hook. Authentication, context injection, location proxying, and blockchain access — all available the moment your component mounts.
