# Bootstrap Liquidity

To bootstrap liquidity, the protocol provides single-sided liquidity for outcome tokens (YES / NO)

In the code below, liquidity is provided for YES.

```solidity
// Solidity
// Assuming YES-USDC where YES is currency0 and USDC is currency1
int24 tickLower = 0;
int24 tickUpper = 600;
uint256 liquidity = 1e18;

PoolManager manager = new PoolManager(500000);
// Helpers for interacting with the pool
PoolModifyPositionTest modifyPositionRouter = new PoolModifyPositionTest(IPoolManager(address(manager)));

modifyPositionRouter.modifyPosition(
    poolKey,
    IPoolManager.ModifyPositionParams({
        tickLower: tickLower,
        tickUpper: tickUpper,
        liquidityDelta: int256(liquidity)
    }),
    ZERO_BYTES
);
```

Bootstrapping liquidity by crowd sourcing helps to reduce operational risk. It also allows users to speculate and realise their returns with guaranteed execution due to utilising the AMM model.
