I recently integrated the LI.FI Widget. Why do I see less routes on the widget as compared to Jumper.Exchange?
Can I simulate a call with the calldata returned from https://li.quest/v1/quote/contractCall e.g. in Tenderly? Should I suppose to use the Executor contract & where to get the exact parameters for swapAndExecute or swapAndCompleteBridgeTokens ?
Is there way to play (integrate) with swap widget on testnets (eg. Polygon Mumbai) ?
Is the difference between toAmount and toAmountMin purely based on the slippage and if this is the case which is the default slippage when calling /quote route?
