Increase Liquidity

Increase Liquidity Within The Current Range

Make sure to go through the first guide before continuing to this section

This example assumes the contract already has custody of the NFT.
We cannot change the boundaries of a given liquidity position using the CenturionDEX v3 protocol; increaseLiquidity can only increase the liquidity of a position.
In production, amount0Min and amount1Min should be adjusted to create slippage protections.

    /// @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
    function increaseLiquidityCurrentRange(
        uint256 tokenId,
        uint256 amountAdd0,
        uint256 amountAdd1
    )
        external
        returns (
            uint128 liquidity,
            uint256 amount0,
            uint256 amount1
        )
    {
        INonfungiblePositionManager.IncreaseLiquidityParams memory params =
            INonfungiblePositionManager.IncreaseLiquidityParams({
                tokenId: tokenId,
                amount0Desired: amountAdd0,
                amount1Desired: amountAdd1,
                amount0Min: 0,
                amount1Min: 0,
                deadline: block.timestamp
            });
 
        (liquidity, amount0, amount1) = nonfungiblePositionManager.increaseLiquidity(params);
    }
