# Boost the Pool by depositing your $sDYSN

## Executing a Boost

As mentioned in previous section, holders can deposit their $sDYSN into the Gauge contract to enhance a corresponding pool's reward generation speed. Explore the [Gauge & Yield Boosting](https://docs.dyson.finance/mechanisms/gauge-and-yield-boosting) section in our white paper for further insights into boosting opportunities.

Two main methods initiate boosting: direct interaction with the Gauge contract or utilizing the Router contract. However, as the Router interaction is equivalent to the Gauge contract, boosting through Router is unnecessary unless you have a specific goal of consolidating multiple interactions into a single transaction. Here, we'll only introduce the boosting method within Gauge.

### Boost within Gauge Contract 

<pre class="language-solidity"><code class="lang-solidity"><strong>// Gauge.sol
</strong><strong>function deposit(
</strong><strong>    uint amount, 
</strong><strong>    address to) external;
</strong></code></pre>

Parameters:

* `amount` : Amount of sGov token.
* `to` : Address that owns the amount of sGov token.

#### Set Up your Contract
