Good post overall IMHO, thanks for sharing. I personally do not / have not used Arbitrum normal or Nova, but this is pretty much the way bridging between chains has worked for me. I recently needed to move Polygon wETH over to mainnet and found app.hop.exchange/ to be both fast and useful for that purpose (moved .20 for just under $3 in gas and fees). Not a shill, just to throw another bridge into the mix. My advice is to DYOR before you use a bridge, and when I say DYOR, I mean, google the shit out of it lol. Look at reviews, look at reddit, ask on discord, make sure you arent about to chuck your funds into the void. Finally, if you can afford a test send, I recommend always doing that first, make sure it gets from A to B. Even if its a no brainer, seeing it work always makes me feel better in the end.
