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 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

// Gauge.sol
function deposit(
    uint amount, 
    address to) external;

Parameters:

• amount : Amount of sGov token.

• to : Address that owns the amount of sGov token.

    uint amount = 100e18; // 100 $sDYSN
    address to = address(this);

    function boost() external {
        IERC20(sDYSON).approve(gauge, amount);
        IGauge(gauge).deposit(amount, to);
    }
}
