# Welcome

Official documentation for **Leviathan**, the privacy and programmability stack built on Neptune and Miden.

> **Status:** Public testnet. Testnet assets have **no real-world value**. This documentation describes the public experience on [leviathandev.neptune.io](https://leviathandev.neptune.io).

## What is Leviathan?

Leviathan combines a **privacy focused base layer** (Neptune, native asset XNT) with a **programmable layer** (Miden, wrapped asset WXNT) connected by a cryptographic bridge. Proofs, not trust, secure value movement between layers.

## Start here

1. [Install the Leviathan Chrome extension](/leviathan/wallets/chrome-extension.md) — download the zip on that page
2. [Request testnet funds](/leviathan/getting-started/request-funds.md)
3. [Send tokens](/leviathan/getting-started/send-tokens.md)
4. [Chat with Private AI](https://ai-tee-leviathan.up.railway.app/) — open-weight models inside attested TEEs

Hosted web wallet docs: [wallets/web-wallet.md](/leviathan/wallets/web-wallet.md). DEX: [NeptuneSwap](/leviathan/neptuneswap-dex/overview.md) at [testnet.zkswap.ai](https://testnet.zkswap.ai/).

## TEE proving (testnet)

Heavy STARK proving can be **delegated** to an attested enclave (Intel TDX on Phala) so builders do not need to run every proof locally. Start here:

* [TEE proving overview](/leviathan/tee-proving/overview.md)
* [Attestation and trust](/leviathan/tee-proving/attestation.md)
* [Set up delegated TEE proving](/leviathan/tee-proving/setup.md)
* [TEE proving FAQ](/leviathan/tee-proving/faq.md)

## Private AI (testnet)

Chat with open-weight models inside attested TEEs. Prompts are end-to-end encrypted. Log in with the Leviathan wallet or a browser account, then buy credits with the wallet or a Stripe sandbox card.
