**Inherits:** [IMaverickV2BoostedPositionFactory](/technical-reference/maverick-v2/v2-contracts/maverick-v2-supplemental-contracts/interfaces/imaverickv2boostedpositionfactory.md)

Factory contract that deploys Maverick V2 Boosted Positions.

### State Variables <a href="#state-variables" id="state-variables"></a>

#### NAME\_PREFIX <a href="#name_prefix" id="name_prefix"></a>

```solidity
string private constant NAME_PREFIX = "Maverick BP-";
```

#### SYMBOL\_PREFIX <a href="#symbol_prefix" id="symbol_prefix"></a>

```solidity
string private constant SYMBOL_PREFIX = "MBP-";
```

#### \_allBoostedPositions <a href="#allboostedpositions" id="allboostedpositions"></a>

```solidity
IMaverickV2BoostedPosition[] private _allBoostedPositions;
```

#### \_boostedPositionsByPool <a href="#boostedpositionsbypool" id="boostedpositionsbypool"></a>

```solidity
mapping(IMaverickV2Pool => IMaverickV2BoostedPosition[]) private _boostedPositionsByPool;
```

#### poolFactory <a href="#poolfactory" id="poolfactory"></a>

Pool factory that all BPs pool must be deployed from.

```solidity
IMaverickV2Factory public immutable poolFactory;
```

#### isFactoryBoostedPosition <a href="#isfactoryboostedposition" id="isfactoryboostedposition"></a>

Returns whether or not input BP was created by this factory.

```solidity
mapping(IMaverickV2BoostedPosition => bool) public isFactoryBoostedPosition;
```

### Functions <a href="#functions" id="functions"></a>

#### constructor <a href="#constructor" id="constructor"></a>

Factory will only deploy BPs from the specified pool factory.

```solidity
constructor(IMaverickV2Factory _poolFactory);
```

#### \_createParameterValidation <a href="#createparametervalidation" id="createparametervalidation"></a>

```solidity
function _createParameterValidation(IMaverickV2Pool pool, uint32[] memory binIds, uint128[] memory ratios, uint8 kind)
    internal
    view;
```

#### createBoostedPosition <a href="#createboostedposition" id="createboostedposition"></a>

Creates BP from the specified input parameters. Requirements:

* Pool must be from pool factory
* BP kind must be supported by the pool
* BinIds have to be sorted in ascending order
* ratios\[0] must be 1e18; ratios are specified in D18 scale
* ratio and binId arrays have to be the same length
* movement-mode BPs can only have one binId
* static-mode BPs can have at most 24 binIds

```solidity
function createBoostedPosition(IMaverickV2Pool pool, uint32[] memory binIds, uint128[] memory ratios, uint8 kind)
    external
    returns (IMaverickV2BoostedPosition boostedPosition);
```

#### lookup <a href="#lookup" id="lookup"></a>

Look up BPs by range of indexes.

```solidity
function lookup(uint256 startIndex, uint256 endIndex)
    external
    view
    returns (IMaverickV2BoostedPosition[] memory returnBoostedPositions);
```

#### lookup <a href="#lookup-1" id="lookup-1"></a>

Look up BPs by range of indexes.

```solidity
function lookup(IMaverickV2Pool pool, uint256 startIndex, uint256 endIndex)
    external
    view
    returns (IMaverickV2BoostedPosition[] memory returnBoostedPositions);
```

#### \_packBinIds <a href="#packbinids" id="packbinids"></a>

```solidity
function _packBinIds(uint32[] memory binIds) private pure returns (bytes32[3] memory binIdsBytes);
```

#### \_packRatios <a href="#packratios" id="packratios"></a>

```solidity
function _packRatios(uint128[] memory ratios) internal pure returns (bytes32[12] memory ratiosBytes);
```
