# Exchange Tier

These staking rates are obtained from exchanges. This tier exists due to the distinctive nature of staking reward rates offered by crypto exchanges, which sets them apart from other providers.

**Exchanges and Staking Methods**

Kraken sheds light on this issue by categorizing staking methods as "bounded" and "flexible." The flexible method allows for immediate receipt of rewards and assets, while the bounded method requires a waiting period before receiving rewards and assets.

Generally, exchanges offer the flexible method, resulting in a lower APY. However, the bounded method provides staking rates comparable to those other providers offer.

**Systematic Computation Method**

The distinction between bounded and flexible methods is not always clear, necessitating the creation of a specific tier for exchanges.

## 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.kaiko.com/formerly-vinter-indices/api/staking-yield-reference-rates/staking-tiers/exchange-tier.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.
