AddLiquidityParams​

    struct AddLiquidityParams {
        address token0;
        address token1;
        uint24 fee;
        address recipient;
        int24 tickLower;
        int24 tickUpper;
        uint256 amount0Desired;

    }

Functions​

dragonswapV2MintCallback​

  function dragonswapV2MintCallback(
    uint256 amount0Owed,
    uint256 amount1Owed,
    bytes data
  ) external

Called to msg.sender after minting liquidity to a position from IDragonswapV2Pool#mint.

In the implementation you must pay the pool tokens owed for the minted liquidity. The caller of this method must be checked to be a DragonswapV2Pool deployed by the canonical DragonswapV2Factory.

Parameters:​

Name	Type	Description
amount0Owed	uint256	The amount of token0 due to the pool for the minted liquidity
amount1Owed	uint256	The amount of token1 due to the pool for the minted liquidity
data	bytes	Any data passed through by the caller via the IDragonswapV2PoolActions#mint call

addLiquidity​

  function addLiquidity(
    AddLiquidityParams memory params
  ) internal returns (uint128 liquidity, uint256 amount0, uint256 amount1, contract IDragonswapV2Pool pool)

Add liquidity to an initialized pool
