# How It Works

The staking contract is described as a pool-based mechanism where each pool has a lock duration and a reward percentage.

## Mechanics

* Users select a pool based on duration
* Tokens are deposited through `stake()`
* The contract tracks the stake and its maturity
* Rewards are added at withdrawal if the lock period is complete

## Example pools listed in the source

```solidity
pools[1] = Pool(30 days, 5%);
pools[3] = Pool(90 days, 20%);
pools[6] = Pool(180 days, 50%);
```

## Example stake structure

```solidity
struct Stake {
    uint256 poolId;
    uint256 amount;
    uint256 startTime;
}
```

The source describes the contract as non-custodial, open-source, and designed for transparent inspection.

## 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.tetreum.com/token-and-governance/staking-mechanism/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.
