+The `outputAmountPercent` field allows specifying the desired output amount as a percentage of the input amount, with two decimal places of precision. For example:
+- 8500 represents 85.00%
+- 9375 represents 93.75%
+- 10000 represents 100.00%
+
+When using `swapAndStartBridgeTokensViaAcrossV3`, the `outputAmount` will be automatically calculated using the specified percentage.

 ## Swap Data
 
 Some methods accept a `SwapData _swapData` parameter.
