Function: _multiSwap(address[] path, address[] pools, uint256[] iValues, uint256[] jValues, uint256 fromAmount, uint256 toAmountMin)

Delegates the swap logic for each swap/pair to _swapEth or _swap.

Inputs

• path

  • Constraints: No constraints.

  • Impact: An array of the tokens being swapped between.

• pools

  • Constraints: No constraints.

  • Impact: An array of Curve pools to swap with.

• iValues

  • Constraints: No constraints.

  • Impact: An array of indexes of the fromToken in each Curve pool.

• jValues

  • Constraints: No constraints.

  • Impact: An array of indexes of the toToken in each Curve pool.

• fromAmount

  • Constraints: No constraints.

  • Impact: The amount of fromToken to swap.

• toAmountMin

  • Constraints: No constraints.

  • Impact: The minimum amount of toToken to receive from the swap.

Branches and code coverage (including function calls)

Intended branches

• If any of the path is address(0), use _swapEth for swapping tokens; otherwise, use _swap.

  Test coverage

Negative behavior

• Revert if amountOut == 0.
