Functions

uniswapV3MintCallback

  function uniswapV3MintCallback(
    uint256 amount0Owed,
    uint256 amount1Owed,
    bytes data
  ) external

Called to msg.sender after minting liquidity to a position from IUniswapV3Pool#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 UniswapV3Pool deployed by the canonical UniswapV3Factory.

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 IUniswapV3PoolActions#mint call

addLiquidity

  function addLiquidity(
    AddLiquidityParams memory params
  ) internal returns (uint128 liquidity, uint256 amount0, uint256 amount1, contract IUniswapV3Pool pool)

Add liquidity to an initialized pool
