Select Destination

Hey, take care of this travel manual. We're going to launch

Now you will see the selector under your NFTs, select Polygon network or any other chain you want to go (Of course, at Stage 1 you can only travel between Arbitrum and Polygon, but we will set up portals for other chains soon! ) and click GO button:

Our Dapp will calculate the required fee of cross-chain, and pop up a dialog box to display it.

As shown in the figure, the traverse fee required by this cross-chain only needs 0.00001027 ETH, which is lower than the GAS fee of Arbitrum, amazing! You know L2 costs are already pretty low. If you are ready to cross chain, click the Traverse button:

You'll see the transaction details on Matamask: Traverse Fee 0.00001027 eth & Gas Fee 0.000383 eth. Then click Confirm button:

Like Gas Fee, Traverse Fee changes all the time. So when you calculate the Traverse Fee, please click the Traverse button as soon, otherwise the transaction may fail due to insufficient Traverse Fee. If there is no confirmation for a long time after calculating the Traverse Fee, please close the dialog box and click the GO button to recalculate
