 * The `minGasPrice` and `gasMultipler` parameters can be adjusted to enhance execution certainty of cross-chain transactions.
-* The response to the method gives a single value (in `wei`) of the total estimated gas required for the cross-chain call. In the GMPParams parameter, there is an option to show a full breakdown of fees instead by specifying `true` for `showDetailedFees`. If you do this, you will have to add the individual components of the fees yourself,
