Increase Liquidity Within The Current Range

See Setting Up Your Contract for the base contract. This example assumes the contract already has custody of the NFT.
  • You cannot change the tick boundaries of a position — increaseLiquidity only adds liquidity to the existing range.
  • In production, amount0Min and amount1Min should be set for slippage protection.
    /// @notice Increases liquidity in the current range
    /// @dev Pool must be initialized already to add liquidity
    /// @param tokenId The id of the erc721 token
    /// @param amount0 The amount to add of token0
    /// @param amount1 The amount to add of token1
