Function: swapETHForToken()

The function is used to buy tokens. If the real ETH reserve reaches a certain threshold, the tokens and the ETH reserve are sent in a DEX pool through a router.

Inputs

• _amountIn

  • Validation: The amount is checked to be bigger than the message value in case ETH amount is used.

  • Impact: The amount of tokens to buy.

• _amountOutMin

  • Validation: The quoted amount is checked to be greater than or equal to _amountOutMin; otherwise, it reverts.

  • Impact: The minimum amount of tokens to buy.

• _address

  • Validation: Checked to be a valid token address by the tokenExists modifier.

  • Impact: The token address to buy.

• _isWETH
