## Read-Only Functions

**getPoolData**

```solidity
function getPoolData(address lp) public view returns (
        uint miningRate,
        uint rateDecimals,
        address token0,
        uint reserveA,
        address token1,
        uint reserveB,
        uint airdropCount,
        address[] memory airdropTokens,
        uint[] memory airdropSettings 
    )
```

* Details of the pool
* Airdrop only between startBlock and endBlock of blocks in the network
* Parameters
  * `miningRate` : MESH distribution ratio numerator value
  * `rateDecimals` : MESH distribution ratio denominator
    * 예) Daily MESH distribution ratio
      * miningRate - 130323276365080043, rateDecimals - 10000000000000000
      * 130323276365080043 / 10000000000000000 = 13.03...%
  * `token0` : LP token0
  * `reserveA` : Amount of token0 held by LP
  * `token1` : LP token1
  * `reserveB` : Amount of token1 held by LP
  * `airdropCount` : Number of airdrop plans in progress at LP
  * `airdropTokens` : Airdrop token address array
  * `airdropSettings` : Airdrop info array
    * \[0]: blockAmount, \[1]: startBlock, \[2]: endBlock
* `airdropSettings` Data format
  * 예) Token0, Token1 Airdrop   
    * airdropTokens = \[ Token0 address, Token1 address]
    * airdropSettings = \[ Token0 blockAmount, Token0 startBlock, Token0 endBlock, Token1 blockAmount, Token1 startBlock, Token1 endBlock ]

**getPendingReward**

```solidity
function getPendingReward(address lp, address user) public view returns ( 
    uint meshReward, 
    uint airdropCount, 
    address[] memory airdropTokens, 
    uint[] memory airdropRewards )
```

* User's claimable reward information
* Parameters
  * `meshReward` : Claimable MESH
  * `airdropCount` : Number of airdrop plans the LP has
  * `airdropTokens` : Airdrop token address array
  * `airdropRewards` : Arrangement of Airdrop token amount Information claimable
* `airdrop` data format
  * 예) Token0, Token1 Airdrop 
    * airdropTokens = \[ Token0 address, Token1 address]
    * airdropSettings = \[ Token0 reward, Token1 reward ]

**estimateSwap**

```solidity
function estimateSwap(
    uint amountIn, 
    address[] memory path
) public view returns (uint amountOut)
```

* MESHswap swap estimate lookup function
* Input Parameters
  * `amountIn` : Token amount to be exchanged
  * `path` : exchange token path
* example
  * WMATIC -> MESH
    * amountIn = 1000000000000000000 ( =1 WMATIC )
    * path = `["0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270",  "0x82362Ec182Db3Cf7829014Bc61E9BE8a2E82868a"]`
  * WMATIC -> USDC -> MESH
    * path = `["0x0d500B1d8E8eF31E21C99d1Db9A6444d3ADf1270",  "0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174", "0x82362Ec182Db3Cf7829014Bc61E9BE8a2E82868a"]`
