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 Uniswap 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

/// @param amount0 The amount to add of token0
