# How it works

Off-ramp widget allows user to exchange their crypto currency to his country's local currency.

How it works for end users:

1. Customer selects off-ramp type and specifies the amount of crypto he wants to exchange. System displays how much local currency he will receive.
2. Customer verifies his email by entering a code sent to him.
3. Customer provides his account details such as bank account number, bank name, etc.
4. System returns a wallet address where customer should send his crypto.
5. Customer sends crypto to the provided address and provides a transaction hash to the system.
6. System checks if the transaction is received and sends local currency to the customer's account.

## 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.fonbnk.com/v1.5/off-ramp/how-it-works.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.
