• from, to, calldata: The calldata could be sent to the to address from the from address to execute the swap. from address should have enough allowance to NativeRouter (which is the to address)

• amountInOffset: The offset position (in bytes) of the param amountIn. For example in the sample response above the amountIn (uint256) is taking the bytes in 100-131. Useful when the user wants to adjust the amount in in calldata.

• amountOutMinimumOffset: The offset position (in bytes) of the param amountOutMinimum. For example in the sample response above the amountIn (uint256) is taking the bytes in 132-163. Useful when the user wants to adjust the amount out minimum (for slippage protection) in calldata.
