Audit ResultsSummary

Function: setPositionWidth(int24 _width)

Allows owner to set the position width and readjust the positions.

Inputs

  • _width

    • Control: Fully controlled by the owner.

    • Constraints: No constraints.

    • Impact: The width of the position will be set to this value.

Branches and code coverage

Intended branches

  • Remove the current liquidity.

  • Set the positionWidth to the new value.

  • Update the ticks.

  • Add the previous liquidity back to the pool.

Negative behavior

  • Should not be callable in periods that are not calm, so that _removeLiquidity and _addLiquidity are not called or slippaged badly.

  • Should not be callable by anyone other than the owner.
