# Off-chain accounts

An off-chain account is the default account for users of tanX which is a platform powered by Starkware. These accounts' balances are stored and managed off-chain (except when moving the funds to/from an on-chain account). From the L1 perspective, the funds of these accounts are stored under the Starkware smart contract.

In this section, we describe the flows that update these accounts. Specifically, a deposit of funds to an L2 account, a transfer of funds to another L2 account, trading tokens from an L2 account, and a withdrawal of funds back to L1.

Moving forward we have described flows that tanX initiates and might affect these accounts on L2, namely minting off-chain assets for spot trading systems, and liquidation, deleverages and price changes in the perpetual trading systems.

## 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, and the optional `goal` query parameter:

```
GET https://docs.tanx.fi/tech/tech-docupaper/transactional-flow/off-chain-accounts.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
