# Veilo Documentation > Official documentation for Veilo, a privacy layer on Solana, and the Cloak API for embedding private token transfers into partner products. Use the Veilo Documentation section for product concepts, user flows, privacy guarantees, and wallet behavior. Use the Cloak API section for partner onboarding, authentication, API endpoints, signing, fees, limits, and operational guidance. Cloak production endpoints use `https://api.veilo.network/cloak/v1`. Partner accounts, API keys, fee wallets, and metrics are managed at `https://partners.veilo.network`. ## Veilo Documentation - [Get started: Introduction](https://docs.veilo.network): What Veilo is: a privacy layer on Solana that breaks the link between your identity and how you move money. - [Get started: Quickstart](https://docs.veilo.network/quickstart): Create an account, fund it, and make your first private transfer. - [Get started: Apps & clients](https://docs.veilo.network/apps): The mobile wallet, browser extension and web app, plus usernames, multiple accounts and encrypted backup. -
