The bridging process made me first "approve" a spending limit (50 DAI to xDai) and then pay separately to actually send the Dai to th the bridge contract thereby releasing the xDai on the Gnosis side. This may have been a mistake on my part.
Conversation
The instructions didn't say anything about a 2-step approve/transfer process, each with its own fees. So I paid about $14 and $9 in 2 transactions to do the bridge transaction. If you're keeping track, I've so far spent about $32... and I have $50 worth of xDai now on Gnosis.

The Gnosis chain uses the same address space as the Ethereum main chain, just on a different blockchain. So your tokens simply live at the same address in a different city sort of. See in the screenshots below the network name is different but the address (0x25...) is the same.

But now, having spent $32 to move $50, I am hopefully in the Land of Cheap Transactions and the 50 xDai will hopefully last me a long time.

The reason for me exploring Gnosis/xDai in particular is because operates on xDai, and they recently did their token sale, in which I got a bunch of their CLNY token for having done some consulting for them in 2017-18.

I got my wallet to recognize the xDai/Gnosis chain easily enough. You go to this page and follow the instructions to add the chain to your Metamask if it's not already there.

But you need xDai to do anything on Gnosis, including in my case claiming my CLNY and my profile on the "metacolony" that governs the Colony DAO software project. Fortunately the good folks at Colony sent me a few pennies worth of xDai, enough to cover my bootstrap needs.

Well, I signed up for Colony, got my CLNY, and made noble plans to set up a DAO there soon, but of course, first I wanted to do the base, degen thing and see what my CLNY was worth. Also my first plan to acquire some more xDai was to sell a bit of my newfound CLNY riches. BUT....

Turns out I didn't actually have enough xDai left after my bootstrapping to even pay for the trade... the Colony people had sent me 0.01 xDai (1c), and I'd spent about 0.0065 already, and I had 0.0035 xDai (~0.3c) left. Not enough xDai to sell CLNY to get more xDai 🤣

I should learn how to do this on the bitcoin side with lightning network stuff. Any easy way to start? Is there a standard browser extension type wallet for bitcoin to do lightning stuff?
i should know the answer to this. it used to be not sure what the answer is today tbh
