User can bypass entryFee by sending arbitrary calldata to ParaSwap operator. Any user can bypass the entryFee collection when using NestedFactory.create() by passing in arbitrary calldata to the ParaSwap router. The Paraswap operator returns the swap amounts back to Nested Factory, which deposits the 1,000,000 USDC to the vault for the user without charging any entryFee
