Function: bridgeEtherToChia(byte[32] _receiver, uint256 _maxMessageToll)

This function is used to bridge native Ether to Chia by first wrapping it into milliETH (or WETH). This function wraps Ether into an ERC-20, sends the portal tip, and sends a message to mint tokens on Chia.

Inputs

• _receiver

  • Control: Arbitrary.

  • Constraints: None.

  • Impact: Receiver puzzle hash for the tokens.

• _maxMessageToll

  • Control: Arbitrary.

  • Constraints: None.

  • Impact: Value of the maximum message toll.

Branches and code coverage

Intended branches

• Call the deposit function of IWETH to wrap the Ether.

  Test coverage

• Call the decimals function of IWETH and update the factor.

  Test coverage

• Invoke the _handleBridging function.

  Test coverage

Negative behavior

• Check if the message toll is less than the maximum message toll.

  Negative test

• Check if the amount after toll is greater than wethToEthRatio and divisible by wethToEthRatio.
