# Smart Engines V3 — Coming Soon

### The trustless multichain operating system.

Smart Engines is decentralized infrastructure that lets you build applications and autonomous agents across many blockchains through **one API and one SDK** — without ever holding private keys yourself.

> **🧠 In plain English**
>
> Normally, building on a blockchain means either running complex infrastructure or trusting a company with your keys. Smart Engines is a third way: a decentralized network does the heavy lifting, keys are split across many machines so no single one can act alone, and the rules that govern everything are enforced on-chain.

***

## What makes it different

* **Keys are never held whole.** Every key is created by a distributed ceremony across the network and used by threshold signing — no single machine ever holds a complete private key.
* **No single point of control.** On-chain actions are authorized by native multi-signature, so no lone operator can move anything alone.
* **Rules are enforced, not promised.** The policies that govern an entity are public and checked on every transaction.
* **Many chains, one interface.** A uniform API and SDK span every supported network, so you write your logic once.

```

### Smart Apps

Deployed, rule-governed applications with their own cryptographic identity and multi-chain wallets. You ship your logic; the network secures it and enforces its rules.

### Smart Agents

Autonomous actors — AI or automation — that get their own identity, their own multi-chain wallets, and a rulebook they **cannot** break, no matter what their code tries to do.

### Host Functions

Serverless-style building blocks for the things every app needs — account provisioning, wallet authentication, token operations, usage metering — all without you ever handling raw keys.

## Status

**The engine is built.** We've completed the core V3 implementation across the platform, and we're now heads-down on the part that matters for adoption: **the documentation**.

We're writing the full guides, tutorials, concept explainers, and the SDK + API reference so that any developer can go from zero to a live, multi-chain Smart App quickly. That work is happening right now.

**Full developer documentation is landing soon.** Thanks for your patience while we make it genuinely great.

*More coming shortly — what's here is a brief preview, not the full documentation.*

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.hsuite.network/readme.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
