Branches and code coverage

Intended branches

• Assure that msg.value is greater than or equal to the native fee. Currently not implemented.

  Test coverage

• In case that user sends more than the native fee, the excess should be refunded. Currently not implemented, as the _refundAddress is set to address(this).

  Test coverage

• Estimate the native fee using lzEndpoint.estimateFees.

  Test coverage

• Call _lzSend with the estimated native fee.

  Test coverage

Negative behavior

• Should not be callable by anyone other than a trusted caller.
