# 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 (only bank transfer is supported now) 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.fonbnk.com/v1/off-ramp/how-it-works.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
