# Internal Address

**Internal Address** - blockchain-address in the [**Sputnik Network App-chain**](/glossary-of-terms-and-scheme/sputnik-network-app-chain.md), which [**Sputnik App**](/glossary-of-terms-and-scheme/sputnik-app.md) creates for the [**User**](/glossary-of-terms-and-scheme/user.md) when creating a [**Personal Account**](/glossary-of-terms-and-scheme/personal-account.md) 

[**Sputnik App**](/glossary-of-terms-and-scheme/sputnik-app.md) has access to the user's **Internal Address** 

When a [**User**](/glossary-of-terms-and-scheme/user.md) transfers funds from a **Internal Address**, it is not the [**User**](/glossary-of-terms-and-scheme/user.md) who signs the transaction, but [**Sputnik App**](/glossary-of-terms-and-scheme/sputnik-app.md) that signs the transaction from the user's **Internal Address** 

The [**User**](/glossary-of-terms-and-scheme/user.md) can link his Telegram, Twitter, Discord usernames and email to the **Internal Address** in the [**Personal Account**](/sputnik-app/personal-account.md)
