Token addresses will be different on xDai and Eth since they’re on completely different chains. For example, this is WETH on the Ethereum chain: $1,819.1000 | Wrapped Ether (WETH) Token Tracker | Etherscan and this is WETH on xDai: TokenProxy (0x6A023CCd1ff6F2045C3309768eAd9E68F978f6e1) - xDai Explorer
xDai is super easy to use. All you need to do is setup the xDai network on Metamask and switch to it when you’re interacting with xDai: Metamask Setup - xDai STAKE
I’m sure they’ll be a Bao specific tutorial in the future. Also, transactions on xDai is paid using xDai instead of something like Eth for gas. You’ll need to send some dai over first in order to transact on xDai. For reference, I paid less than 0.000334 xDai to delegate STAKE a few weeks ago so it’s super cheap.
Tokenomics should not be affected much since farming rewards on Ethereum will go from 1000 base Bao per block to 250 and farming rewards on xDai will go from 0 base Bao per block to 750. TheBaoMan did mention that the block times are different between the two chains but he will try to keep the halving phase not more than a week apart so there should be minimum effects.
